Description

Ultrasonic periodontal device, system and using method

Technical field

[0001] the present invention relates generally to the periodontal medicine field, and relate in particular to ultrasonic technique is applied to periodontal medicine and common dentistry.

Background technology

[0002] the periodontal gingival are the severe infections in oral cavity, if do not add treatment, then can cause absence of tooth and relevant issues, and suspect that the periodontal gingival are with cardiac trigger onste, apoplexy, diabetes, respiratory disorder, premature labor/underweight baby even death.

[0003] periodontal disease can influence perhaps many teeth of a tooth.During beginning, the antibacterial in the bacterial plaque (often being formed on the stickiness on everyone tooth, colourless thin film) causes gingival infection and inflammation.

[0004] in the slight form (gingivitis) of this disease, gingiva reddens, enlargement, hemorrhage easily.Usually seldom or do not have a discomfort.Gingivitis particularly lacks and uses dental floss to cause often by unsuitable oral hygiene.Gingivitis is reversible under specialty treatment and good oral cavity home care.

[0005] gingivitis that does not add treatment can develop into periodontitis.As time goes on, bacterial plaque can hardening become calculus, and spreads below the gum line and grow, and here, calculus can become the breeding ground of the following antibacterial of gum line.The toxin that antibacterial produced in bacterial plaque and the calculus continues to make gingiva and surrounding tissue pain and inflammation.Along with infection becomes more serious, toxin evokes chronic inflammatory reaction, and wherein health is being attacked self in essence, and the tissue of supports tooth (ligament) and bone are damaged and damage.

[0006] periodontal soft tissue (gingiva or gums and periodontal ligament) separates with tooth, forms the periodontal pocket (space between tooth and the periodontal tissue) that is infected.Along with the development of this disease, produce increasing destructive toxin, the result, periodontal pocket is deepened, and more polydonita week tissue and bone be damaged and damage.At first, this destructive process can not have symptom.At last, it is loosening that tooth can become, and may lack or have to and pull out.Dissimilar antibacterials can be individually or jointly be present in human oral cavity more than 300 kinds.Because the periodontal disease doctor will attempt various antibiotic and therapeutic modality up to developing effective treatment plan, therefore make to the treatment difficulty of periodontal disease, time-consuming and expensive.As any other severe infections, if in time treat without the antibiotic of right type and dosage, periodontitis can cause serious systemic infection (it can cause many other serious diseases, even threat to life) so.Because patient's immune system will be fought with this chronic and perhaps serious infection, so this can create the chance of other serious disease of infection such as heart disease, apoplexy and diabetes.

[0007] odontologist and toothwash teacher (dental hygienists) detection and the employed existing operational approach of measurement depth of pocket are a kind of primary operational approach, comprise sharp metal probe, be used to insert between tooth and the gingiva, and manually, run into the resistance of ligament up to it toward pressing down.The degree of depth that arrives ligament obtains measuring thus, and indicates the clinical damaged numerical value (ligament damaged) that adheres to, and it can indicate the quantity of the periodontal disease that may exist.This method is normally painful concerning the patient, wound is arranged, bleed, inaccurate and subjective.Owing to be difficult in the power that applies same amount in each measurement, cause that very High variation is arranged between examiner self and the examiner in measurement, so this be especially inaccurate and subjective.Because the examiner does not know that the type of existing tissue under the gum line and probe touch or pierce through this tissue, so increased difficulty.In addition, dentist has increased risk to the exposure of hepatitis, HIV and other infectious disease to the exposure of blood samples of patients.

[0008] in addition, therefore existing operational approach has limited it as the effectiveness of diagnosing the instrument of periodontal disease in early days owing to being retrospective analysis and can only measuring the tissue that has lost significant quantity.In addition, this method typically needs to carry out this test with two people, actual examiner who does measurement and the recorder that measures of hand-kept usually.The examiner is normally such as odontologist, toothwash teacher or periodontal disease doctor's Dental Hygienist expert.The recorder also can be the Dental Hygienist expert, but also can be the individual with less technical ability such as the clinic assistant.Another problem that odontologist faces is the long-term trend that are difficult to determine status of patient, because all information are included in a large amount of (that is simulation) made of paper records of crossing over many years usually.As a result, only examine one or two nearest record usually, be used for and current test result relatively, but this may be not enough to the periodontal situation that reflects that accurately the patient is running down.

[0009] the another one problem about existing manual probe operational approach is that it typically can destroy agglutination.Trial and error method can be torn the tissue of new healing, and can make recovery from illness prolong several weeks or several months.In addition, it can allow antibacterial enter wound and patient's blood flow, and this can cause infecting (that is bacteremia).In fact, dissimilar antibacterials can be individually or be present in people's oral cavity in combination more than 300 kinds.Because the periodontal disease doctor will attempt various antibiotics and therapeutic modality up to making effective treatment plan, so this makes treatment periodontal disease difficulty, time-consuming and expensive.

[0010] Fig. 1 suffers from the sketch map that the tooth 106 of periodontal disease compares to left side healthy tooth 100 and the right.Healthy tooth 100 has the bone height 104 of complete health, healthy periodontal ligament 103 and healthy gingiva/gums 102.Ill tooth 106 presents the absorption that gingiva/gums disappearance 116, periodontal ligament are adhered to damaged (clinical adhere to damaged) 115 and phatnoma bone height 114, and it causes the formation of periodontal pocket 112.Ill tooth 106 also presents the growth of bacterial plaque 108 and tartar/calculus 110.If the periodontal situation does not obtain diagnosis and corrects, so ill tooth may lack or have to and pull out.

[0011] Fig. 2 is the more detailed sketch map about tooth shown in Fig. 1 100,106.Tooth 100,106 has enamel part 118 and root of the tooth part 120.Root of the tooth part 120 is connected to gingiva 122 by periodontal ligament 126.The top of gingiva 122 is called gum line 124.As shown in Figure 2, gingiva 124 has been shunk back.Yet, in some cases, gingiva 122 possibility inflammation, and owing to edema causes 124 risings of gum line.

[0012] are coboundaries 130 of periodontal ligament 126 at the top of periodontal ligament 126.Between the coboundary 130 of periodontal ligament 126 and enamel part 118 is junctional epithelium 128.In Jiankang tooth 100, the coboundary 130 of periodontal ligament 126, the bottom of junctional epithelium 128 and enamel part 120 are met at glaze-cementum circle 132 places.In ill tooth 106, tartar or calculus 110 and neutrophilic granulocyte 138 spread the periodontal ligament 126 that enters junctional epithelium 128 and opening periodontal pocket 112.If periodontal pocket 112 is between gum line 124 and glaze-cementum circle 132, patient's situation is called gingivitis so.If periodontal pocket 112 extends to glaze-cementum circle below 132, patient's situation is called periodontitis so.In addition, the growth of periodontal pocket 112 may be irregular and be caused intermediate features 136.

[0013] frequent, do the measurement of the output degree of depth in advance with respect to gum line 124.Yet as mentioned above, gum line 124 can be owing to shrinking back or edema changes.Therefore, in measuring the bag degree of depth, use gum line (the perhaps free margin of gums) 124 can cause the measurement inaccuracy and the wide variation of bag degree of depth.Opposite with gum line 124, the position of glaze-cementum circle 132 remains unchanged.Therefore, in measuring the bag degree of depth, use glaze-cementum circle 132 that better and more consistent method about measuring in time is provided, and it is preferred.Manually survey also in order to determine whether there is calculus below the gum line, at which tooth and accurate location.This method can be coarse.

[0014] therefore, want to obtain be a kind of can use gum line and glaze-cementum circle 132 the two as reference, periodontal is adhered to damaged painless, the noinvasive, accurately and have a method that repeatability is measured of carrying out.What also want to obtain is a kind of being used for to determine whether have calculus and the accurate method on which tooth below the gum line.

The specific embodiment

[0061] and detect and measure periodontal to adhere to damaged conventional method opposite, system and a method according to the invention has merged ultrasonic technique.This system and method gives that odontologist and patient thereof provide painless, noinvasive, do not bleed, very accurate, objective, automatic, quick, digitized and inexpensive method, be used for diagnosing effectively, detecting and to assess adhering to of relevant periodontal disease damaged, create digital dentistry record, and come monitor therapy via successive measurement.This system adopts analogue measurement, and will simulate ultrasonic measurement and convert numerical data to, and calculating depth of pocket (preferably, from gum line and glaze-cementum circle both to the distance of pericemental coboundary).The method according to this invention makes the odontologist can be in the earliest stages of periodontal disease (treatment at this moment not only easily but also cheap), and detects periodontal disease in the weakened immune system of health before being easy to infect other disease.By providing, also allow odontologist easier and clean its patient's tooth effectively about before cleaning and be present in the gum line afterwards with the qualitative information that the calculus on the dedendum flank (that is, hardened bacterial plaque) exists.In addition, owing to eliminated between the examiner in essence and examiner's self variation, so this method is independent of the examiner in essence.

[0062] opposite with the art methods of diagnosis periodontal disease, periodontal of the present invention system allows the digitized ground stack patient's of odontologist the Pretesting of work as, and easily with apace with it and be included in some in patient's the electronic medical record, many or whole tests formerly compares.The attendant advantages of periodontal of the present invention system comprises that this test can only be undertaken by a people (opposite with two people), and its typically only need four minutes (with about ten minutes opposite) finish.

[0063] a preferred embodiment of the present invention is shown in Figure 3.In this embodiment, periodontal system 200 comprises mobile phone 202 and display/controller unit 204 (Fig. 4).Display/controller unit 204 comprises and is used to control, circuit board (not shown) and software, the data storage (not shown) of collection and processing signals, be used to preserve liquid reservoir 236, at least one liquid stream adapter 240, electric connector 238 and software and data storage as the liquid of signal coupler.Display/controller unit 204 is preferably compact, but comprises big touch screen 205.Because display/controller unit 204 comprises the liquid reservoir 236 of himself, so it can be used for not having the place of water supply.In addition, liquid reservoir 236 does not need to be positioned at that side of display/controller unit 204 as shown in FIG..For example, it can be positioned at the bottom or the rear portion of display/controller unit 204.In addition, for the purpose of this disclosure, word " liquid " comprises gel.

[0064] described software comprises advanced Discrimination Analysis Algorithm.Randomly, it can also comprise the diagnostic medical imaging ability.Periodontal system 200 uses ultrasonic signal (promptly, the sonar ripple), begin (promptly from glaze-cementum circle 132 to detect, to quantize and to describe to the coboundary 130 of the periodontal ligament 126 of gum line below 124, the degree of depth of the periodontal pocket 112 of every tooth), also provide simultaneously about at the gum line more than 124 or the qualitative information of the existence of following calculus and bacterial plaque 110,108.Periodontal system 200 will simulate ultrasonic signal and convert digital signal to, and the bag degree of depth 112 of every tooth 106 of digitized storage and over time.This has greatly helped the diagnosis of odontologist, and this will as the degree of periodontal disease and severity with and the index of the effect of treatment plan.Preferably, the whole complete computerizing that tests, and carry out the people of this test can digitized ground all patient informations of record.Preferably, odontologist once imports the master data (for example, the position of disappearance tooth or bridge) about every tooth, and it will appear on all screens subsequently.

Algorithm

[0065] Discrimination Analysis Algorithm of periodontal system 200 is used mapping algorithm, will convert a bag degree of depth reading from the ultrasonic waveform that transducer receives to.This algorithm uses signal processing technology, and it is generally used for telecommunication, to detect low level signal and it is separated from background noise.

[0066] this algorithm divides three steps to carry out: waveform processing, peak value detect and peak value is differentiated.

Wavelet transformation

[0067] in one embodiment, use sombrero (Mexican Hat small echo is carried out continuous wavelet transform (CWT) on primary signal, Ψ s (x):

Ψ(x)＝2πw ^-1/2[1-2π(x/w) ²]e ^{-π(x/w)^2}

And

Ψ _s(x)＝s ^-1/2Ψ _s(x/s)

Wherein:

The width w of small echo is set at 1.2 in one aspect of the invention, and

The yardstick s of small echo is set at down train value: 3.5,4.21,5.26,6.58 and 7.89.The width of small echo and the selection of yardstick should be target with the frequency range of 10MHz transducer.Then, the wavelet transformation of function f equals:

W(s，t)＝∑f(x)Ψ _s(x-t)

Small echo is selected

[0068] select mexican hat wavelet (referring to Figure 36) to be because,, provide better temporal resolution than such as more manying the small echo of vibration comprising of Morlet small echo (Figure 37) with only 1.5 " vibration (oscillation) " in the small echo.Compromise place is to have reduced frequency resolution.For present embodiment of the present invention, temporal resolution is typically more important than frequency, and the scope of frequency is to be determined by the natural frequency of transducer crystal.

[0069] unlike employed many other small echos among the CWT, mexican hat wavelet does not have imaginary component.Therefore, in order to determine there is out-phase frequency (out of phase frequency) in the primary signal, also to carry out wavelet transformation with Hilbert (Hilbert) conversion of mexican hat wavelet.

[0070] carrying out Hilbert transform produces pi/2 in this signal phase shift on the time-based signal.Putative signal g (t), then the Hilbert transform of this signal is defined as:

$\hat{g}\left(t\right)=\frac{1}{\mathrm{\π}}\underset{-\∞}{\overset{+\∞}{\∫}}\frac{g\left(\mathrm{\τ}\right)}{t-\mathrm{\τ}}\mathrm{d\τ}$

[0071] the another kind of ways of writing of this definition thinks that Hilbert transform also is the convolution of function 1/ π t and signal g (t).The convolution of two functions is inverse fourier transforms of product of Fourier (Fourier) conversion of these two functions:

[0072] thus we above-mentioned equation can be write as:

$\hat{g}\left(t\right)=\frac{1}{\mathrm{\πt}}*g\left(t\right)$

The Fourier transform of [0073] 1/ π t is:

$F\left(\frac{1}{\mathrm{\πt}}\right)=-\mathrm{jsgn}\left(f\right)$

Wherein:

$\mathrm{sgn}\left(f\right)=\left\{\begin{array}{cc}1& f>0\\ 0& f=0\\ -1& f<0\end{array}\right.$

[0074] therefore, in order to calculate the Hilbert transform of Mexico's small echo, at first calculate the Fourier transform of small echo.Secondly, DC component and Nyquist (Nyquist) frequency component are set at zero.Positive then harmonic function (positive harmonics) multiply by-j, and negative harmonic function multiply by+j.On this result, carry out inverse fourier transform at last, with the Hilbert transform (referring to Figure 36) that obtains this Mexico's small echo.

[0075], calculated the wavelet coefficient after wavelet coefficient and the conversion, and preferably it has been enrolled this algorithm as constant in order to increase the processing speed in when operation.

Yardstick is selected

[0076] in order to determine the relation between wavelet scale and the signal frequency, the sine wave with given frequency is analyzed, to determine to produce the yardstick of higher primary school wave-amplitude.Best scale and frequency be inversely proportional to (Figure 38).Select the range scale in the intrinsic frequency band of transducer, and determine corresponding yardstick (referring to table 1).

Table 1

Frequency (MHz)	The sombrero yardstick
		6.66	3.5
8	4.21
		10	5.26
12.5	6.58
		15	7.89

[0077] periodontal system 200 (Fig. 3) can comprise digital image and diagnostic tool, is used for detecting effectively, surveys and draws, characterizes and assesses described existence the (presence), and the treatment of monitoring periodontal disease.Preferably, it also provide about be present in gum line 124 with the important of the calculus on the dedendum flank (that is, hardened bacterial plaque) 110 (Fig. 2) Useful Information, described calculus is held antibacterial and is hindered oral hygiene.

[0078] use, mobile phone 202 (Fig. 9) guide the water to continue to drip or drip to the gingiva between periodontal tissue and the tooth 100,106.In one embodiment, then, odontologist uses on the pedal each burst (burst) that comes activation signal in three buttons.This allows odontologist to carry out three standards probes (probe) on the face side of every tooth and tongue (tongue) side.A button advances to next position, a button activation signal, and where necessary, a button allows odontologist to return and test last speckle.If correctly picked up signal is then notified odontologist with audible sound, perhaps then do not use different sound notification odontologist if correctly receive signal (software is thought unusual reading).Transducer 227 in mobile phone 202 tips (referring to Figure 10,34), use is applied to the antibiotic or sterilization gel of gingiva, perhaps drop onto water on the gingiva (perhaps such as other liquid of the solution that comprises antibacterial or antibacterial) as signal coupler, with ultrasonic signal (promptly, the sonar ripple) is transferred to the gum line and (, and enters periodontal pocket 112) below 124 along the surface of every tooth 100,106.Described signal can also use the following saliva of gum line as signal coupler.Transducer 227 is caught the corresponding echo that produces with the normal and/or abnormal anatomies feature collision below 124 of gum line.Each signal is come and gone the used time to be measured.Measure according to this, can determine that this signal propagates into the distance of the feature that causes reflection.Use this information, the advanced Discrimination Analysis Algorithm of system 200 can to medical personnel provide painless, noinvasive, very accurately and fast, automatically, digitized and user-friendly method, so that the real conditions of dissecting about patient's periodontal and the important information of gum line every dental surface below 124 to be provided.

[0079] in other embodiment of the present invention, display/controller unit 204 (Fig. 3) can be directly connected to existing water supply.Randomly, circuit board can become this conversion of signals a series of user-friendly images.In one aspect of the invention, display/controller unit 204 comprises keyboard and mouse rather than touch screen.In another embodiment of the present invention, system 300 (Fig. 4) comprises controller unit 304.Be similar to display/controller unit 204, controller unit 304 comprise data storage (not shown), cistern 236, current connector 240, electric connector 238 and be used to control, the circuit board (not shown) of collection and processing signals.Opposite with display/controller unit 204, controller unit 304 does not comprise display.In this embodiment of the present invention, controller unit 304 is connected to the existing computer monitor of medical personnel.This connection can be by connecting such as the hardwired by USB port or realizing such as the wireless of bluetooth.

[0080] embedded software in the computer converts this signal from analog to number format, and use algorithm to explain and (for example convert size to corresponding to the echo of the degree of depth of periodontal ligament external boundary, with the millimeter is the bag degree of depth of unit), and detect the gum line 124 or more or calculus 110, feasible can being removed more easily and effectively to exist on the dedendum flank.

[0081] display chamber system device unit 204 receives the analog information that mobile phone 202 is produced, and this data transaction is become number format, and the operational analysis algorithm is handled to it.Preferably, periodontal system 200 also comprises dental imaging software, is used for creating the user friendly image (as Fig. 5-7 as shown on screen) of applicable tooth 100,106.These images can be presented on the big color touch screen of display/controller unit 204.If the test result on another screen in its dental treatment chamber (operatory) will be checked by odontologist, display/controller unit 204 will be based on the screen that these images is sent to this odontologist wireless or wiredly so.Odontologist can use big, the user friendly touch screen of display/controller unit 204 or keypad to import all patient informations.In another aspect of this invention, odontologist can use speech recognition software to import all patient informations.In addition, this system uses its fast water fittings of connection/disconnection and electric fittings and move apace easily between a plurality of dental treatments chamber.

[0082] software that is preferably incorporated in the system 200 (Fig. 3) preferably allows display/controller unit 204 to show the result 208 (Fig. 6) and the case control 210 (Fig. 7) of periodontal measured value 206 (Fig. 5), pictorialization.In one embodiment, around this software can generate the image of the tooth of periodontal tissue is arranged, and on this dental imaging, data are shown.Like this, medical personnel and patient can monitor the process and/or the treatment of periodontal disease intuitively, and/or the removal of the following calculus of gum line.

[0083] preferably, calibration periodontal system 200 before every patient is checked.Calibration can comprise testing software, calibration head, testing transducer and/or test acoustic lens.For example, calibration can realize by the degree of depth measurement to the known nest hole (known cavity) of structure in the unit 204.If periodontal system 200 breaks down, so that can not in the clinic of health care provider, recalibrate, system 200 can randomly have automatic message sending and receiving (automatic messaging) so, and it can be by supplier to new system 200 or the transmission of a part wherein request.

[0084] in one embodiment of the invention, all tests will be connected to the third party website via the Internet odontologist or toothwash teacher and carry out later on.This will allow this third party affirmation periodontal system 200 before each test correctly to be calibrated and work capitally, and the account of odontologist has correctly been collected test fee.Patient information can be stored in the centralized backup database of being kept in its website by the third party that meets HIPAA safely.In this embodiment, odontologist will controllably visit this website, and can:

Examine their patient's record;

Examine and upgrade their accounts information;

Examination is also upgraded their disposable stock and sequence information; And

Examine the state of (or a plurality of) system in their clinic.

[0085] in one embodiment of the invention, as shown in figure 12, realize being connected with third-party with enterprise portal software 500.In this embodiment, for backup purpose, the dentistry record can be stored in third party's website.In addition, dentistry record (comprising its digital picture) can transfer to the periodontal disease expert, is used for the online consultation of doctors.Periodontal disease expert can assess patient situation, and its assessment and suggestion sent to the third party or directly send to odontologist or toothwash teacher that the patient is going to a doctor.In addition, this enterprise software can be monitored the activity of odontologist.This system can be used in and determines that slight periodontal problem is successfully treated by which odontologist and which can not.In addition, it can be used in the identification patient that treating of odontologist because the severity of this status of patient and should being treated by the periodontal disease doctor.In addition, via the user according to upgrading available announcement request, perhaps supplier's (if service agreement is ready) simple download automatically, can easily upgrade is used for the software of periodontal system 200.In yet another embodiment, the dentistry record can be encrypted.

[0086] this system allows odontologist to go up at its computer screen (rather than from for many years paper record) and to its patient test result is shown, and the printout of test also is provided to the patient.This allows the patient to confirm that its odontologist tells their content, and the effect of monitoring odontologist treatment plan.The expectation that this active patient participates in causes more patients to observe the indication of its odontologist, because the periodontal disease therapeutic scheme that they can see them just in action.It is returned patient (and their requestee) objective evidence that has periodontal disease and be necessary to treat is provided.This expectation reduces the quantity of " patient that rings off (walkaways) " (that is, not believing the patient of the order of severity of their odontologist or their periodontal situation).

[0087] do not suffer from periodontal disease if the patient is current, so by baseline digital picture and image through back acquisition are after a while compared, odontologist and patient can both see and not have periodontal disease.

[0088] according to one embodiment of present invention, the periodontal examiner sets up the baseline (Fig. 2) of its patient's depth of pocket 112 during trial inspection.After they check first, whenever the patient accepts new inspection, can digitized ground and automatically compare from the data of formerly checking with current data, and illustrate with the dentistry software for display of periodontal system 200.This allow odontologist and patient thereof to identify to use existing manual probe method in addition can't detected depth of pocket 112 in quite slight change.This slight change can illustrate with colored Trendline, with improvement, deterioration or the not change of reaction bag situation.In one aspect of the invention, can detect the change of about 0.2-0.5mm.In another aspect of the present invention, can detect the change of about 0.1-0.2mm.This allows to be in its commitment and can be easily and begin treatment when treating at an easy rate in periodontal disease.

[0089] periodontal system 200 provides following considerable interests to patient, dentistry medical personnel and requestee:

For the patient, this test be objective, noinvasive, painless, do not bleed and cheap.

For odontologist, this test is quick, accurate, objective and digitized.Odontologist provide the papery of test result or the copy of electronics can be immediately for patient and requestee, and expectation substantial extra traffic of generation from additional periodontal test and early stage periodontal disease therapeutic takes is taken in.Treatment is that necessary evidence can be shown to the patient and send to the requestee by Email on screen.Backup copy about every patient's digital record can be stored in long-range website in the mode that meets HIPAA.

For the requestee, comprise third party requestee, the existence and the degree of periodontal disease confirmed on accurate, the objective and digitized ground of this test.Increasing dentistry insurance company and other requestee require the digital evidence about status of patient from odontologist, to confirm that treatment is necessary.

[0090] if there is periodontal disease, the type and the degree of the periodontal disease that is in the initial period can be detected and diagnose in odontologist quickly and accurately, provide preventative-therapeutic doctor's advice and execution and carry out the management of middle periodontal disease, with prevent that it from spreading, the disappearance of ill tooth 106 and the outbreak of other serious disease, and reduce health care costs.By using during treating every the digitized data of some months acquisition and the image of generation, odontologist and patient can both promptly confirm the effect of treatment plan.

[0091] result of such preventive dentistry scheme produces better dental care to the patient.In fact, the expectation execution of most of odontologist is more checked and is treated the patient that those suffer from slight periodontal disease, otherwise this slight periodontal disease will develop into more serious periodontal disease, and gives the periodontal disease doctor then and treat.Those current patients that suffer from more serious periodontal disease will still give the periodontal disease doctor.

[0092] compare with the standard manual probe analogy method (its needs repeatedly, often are sorely with sharp metal probe insertion tooth and the slit between the gingiva) that odontologist and toothwash teacher are used for the existing use of periodontal test institute, periodontal system 200 provides more accurate and detailed information.This manual probe analogy method is inaccuracy and can estimating more than the 1mm patient's real conditions is high or low very.As a result, to be in the periodontal disease in stage very early be unusual difficulty to the diagnosis of existing manual probe method.Even if same odontologist, perhaps different odontologist carry out the periodontal inspection to same patient, can both draw the measurement of significant difference.The reason that this situation takes place has a lot, comprises that probe always is not positioned at the amount of accurate same position, the power that applies, has granulation tissue, odontologist or toothwash's teacher technology and experience, patient's motion etc. owing to infection.

[0093] by contrast, the dental imaging technology of periodontal system 200 provide a kind of obviously more accurate, consistent for periodontal disease, repeatably measure and diagnose, and therefore early stage disease treatment chance, since its error span only is+/-0.1 to 0.5mm, and can discern and treat minimum change easily apace.Preferably, error span is 0.1-0.3mm.More preferably, error span approximately is 0.1 to 0.2mm.

[0094] except diagnosis, periodontal system 200 can be used for the progress of monitoring healing during treating.The progress of monitoring healing is possible during treating, because system and method for the present invention is noninvasive, and does not tear or destroy soft tissue in the healing during use.This is opposite with the conventional method of measuring periodontal disease, and conventional method need be inserted sharp probe between tooth 106 and gingiva 102, and this can tear the tissue in the healing.

[0095] in another embodiment of the present invention, periodontal system 200 can be used for the treatment of auxiliary periodontal disease.In this embodiment, medicine is added to unitary liquid reservoir 236 or to the liquid of mobile phone 202.In yet another embodiment, system can detect the calculus 110 of gum line 124 to exist on lower teeth 106 surfaces, therefore can remove calculus effectively easilier.In addition, can monitor the integrity that the calculus 110 of calculus 110 is removed by using system 200 subsequently.

[0096] an alternative embodiment of the invention allows odontologist or toothwash teacher to determine that they want to obtain how many times and measure on every tooth.This embodiment comprises software, and it allows a large amount of numerical datas collected and storage are handled.This software will make odontologist can obtain and store its patient's data on its office computer.In one aspect of the invention, odontologist or toothwash teacher can be with continuous-mode operation periodontal systems 200.In this pattern, in case trigger, mobile phone 202 is repeat its transmission pulse automatically regularly.The surface that the dental examination person makes probe tip cross over tooth scans adjacent diastema from a diastema.Preferably, the dental examination person carries out first continuous sweep along the facial surface of tooth, and carries out second scanning along the lingual surface of tooth.By this way, can produce the profile of the bottom of bag, and be not only to collect data from several representative points.The sum of fetched data point depends on that the frequency of transducer and dental examination person drag the speed that mobile phone 202 is crossed over tooth 100,106 in this embodiment.Can obtain tens, hundreds of even several thousand data points.By this way, the focal disease in the periodontal pocket 112 can obtain detecting.In aspect of this embodiment, so odontologist or toothwash teacher can be scanned ground tooth 100,106.In aspect another of this embodiment, only to those teeth 106 that before had been defined as showing periodontal disease with continuous mode scanning, the trigger impulse that remaining tooth 100 usefulness disperses scans.In aspect another of this embodiment of the present invention, geo-location (geopositional) technology can be used in combination the fixed reference in the oral cavity, with the position and the profile of auxiliary definition periodontal pocket 112.

[0097] an alternative embodiment of the invention can obtain accurate reading of complete sum height and the 3-D image about all teeth of patient, and may no longer need odontologist to obtain the dental x mating plate.

[0098] among Fig. 8 and 9 one embodiment of the present of invention has been shown.This embodiment provides the mobile phone 202 with straight hand lever 214.An end of handle 214 comprises cavity 216, and it is suitable for holding the transducer (not shown).What be close to cavity 216 is alignment slot 218.Outthrust in alignment slot 218 and the disposable cover (removable cover) 212 closely cooperates.The combination of alignment slot 218 and outthrust has improved aligned reliability when placing new disposable cover 212 on handle 214 widely.What be positioned at handle 214 middle bodies is first circumferential slot 220.In one embodiment of the invention, first circumferential slot 220 has the helical spring (not shown).When the appropriate location disposable cover 212 shifted onto on the handle 214, the groove in this helical spring and disposable cover 212 inside closely cooperates, and it provides snap-fitted.What be positioned at handle 214 middle bodies equally is second circumferential slot 222.Preferably, O type ring is inserted in second circumferential slot 222, so that sealing to be provided.Disposable cover 212 comprises the head part 224 that covers transducer and launches hyperacoustic probe tip 226.In one aspect of the invention, disposable cover 212 can have security feature, and it makes disposablely can not reuse after covering on first use.In another aspect, disposable cover 212 comprises the recognition feature such as serial number.Periodontal system 200 can have pick off, to read this recognition feature and to determine whether this disposable cover 212 is used.If this disposable cover 212 has been used, then further inspection can be refused to allow by periodontal system 200, up to new disposable cover 212 is provided.

[0099] in one embodiment of the invention, the size of probe tip 226 is suitable for cosily including in interdental diastema.Because the position in this gap does not change, so it is provided for obtaining the permanent datum of periodontal measured value.This mobile phone 202 has superiority especially, because probe tip 226 can be positioned at the mastoid process back.In this configuration, mobile phone 202 can be used in measures the periodontal tissue's (burr (specula) of gingiva 102, periodontal ligament 103,126 and interdental bone) that worsens owing to periodontal disease.

[00100] in optional embodiment of the present invention, periodontal system 200 comprises mobile phone 402, as shown in Figure 13 and 14.The inventor recognizes, if transducer 227 is positioned at next-door neighbour's probe tip 426, then significantly strengthens the efficient of ultrasonic probe.On the other hand, owing to pay close attention to the infection of disease, therefore be necessary the part that probe enters in patient's mouth is sterilized.The inventor determines that unfortunately all the existing sterilizing methods such as autoclaving and Chemical cleaning can both damage transducer 227, and As time goes on service life and the degree of accuracy thereof to mobile phone causes harmful effect.

[00101] inventor finds, the mobile phone 402 of present embodiment can be equipped with detachable cover 412 at an easy rate.Use this layout, transducer 227 can be arranged in the head 424 of mobile phone 202 contiguous probe tips 426.In one embodiment of the invention, after the periodontal inspection, can remove and throw away detachable cover 412, and new detachable cover 412 is put on the head 424.In another embodiment of the present invention, detachable cover 412 can be reused after sterilization.That is, detachable cover 412 can be removed from mobile phone 202, sterilization respectively, and reconnect to handle 414.In another aspect of this invention, use the electric connector 238 and the liquid stream adapter 240 of connection/disconnection fast, mobile phone 202 is connected to display/controller unit 204 (Fig. 3), this feasible this system of fast moving between the dental operation chamber easily.

[00102] Figure 10 illustrates an alternative embodiment of the invention.In this embodiment, mobile phone 202 comprises acoustic lens 228.The inventor finds, by the sound wave of concentrating from transducer 227 with acoustic lens 228, can significantly strengthen the efficient of mobile phone 202.Typically, the area of transducer 227 substantially exceeds the outlet opening area of the probe tip 226 of mobile phone 202.Under the situation that does not have acoustic lens 228,, therefore rebound in a large number from the sound waves of transducer 227 from the inwall of probe head 224 because probe head 224 narrows down towards most advanced and sophisticated 226.Yet under the situation that acoustic lens 228 is arranged, sound can be concentrated the size into the outlet opening of probe tip 226.

[00103] in another embodiment of the present invention, the transducer 227 of mobile phone 202 is operated with intermediate frequency.As everyone knows, high frequency sound wave produces higher resolution, and low-frequency sound wave has higher penetrating power.Typically, the Vltrasonic device of prior art is designed to when needing high penetrating power the frequencies operations with 2-5MHz, and when needing high-resolution with the frequencies operations of 15-20MHz.In one aspect of the invention, the inventor finds that the transducer 227 of frequency of utilization between 5 to 15MHz can not only produce high-resolution but also produce high penetrating power.In a preferred embodiment of the invention, the frequency of transducer approximately is 10MHz.
