The present invention provides an aesthetically pleasing, toothless diagnostic prosthesis that can be carried away by a single visit to a patient, while not interfering with the need for multiple adjustments of the bite relationship in sequential therapy. The patient can set requirements for aesthetic effect of front teeth and overall occlusion relation at any time, reduce the number of re-diagnosis, improve the communication efficiency of doctors and patients and reduce the expenditure of various medical materials.
Description
Technical Field
The present invention relates to a diagnostic prosthesis and a method for producing the same.
Background
Patients with severe dentition abrasion due to gastroesophageal reflux, acidic food or drink, night-time teeth or congenital enamel hypoplasia need full-mouth bite reconstruction to restore the patient's chewing, pronunciation, aesthetic appearance and relief of symptoms such as temporomandibular joint discomfort. The three stages of wearing the removable bite block, wearing the diagnostic prosthesis and wearing the final prosthesis are generally experienced during the full-mouth bite reconstruction/elevation treatment, and functional design and aesthetic requirements are continuously adjusted and verified in the first two stages to improve the success rate of the final prosthesis.
During sequential treatment of bite reconstruction/elevation, the process of removable bite pads and donning the diagnostic prosthesis is critical, which is typically over 3 months. Firstly, continuously adjusting newly established occlusion position relation by using the removable bite pad, changing the removable bite pad into a diagnostic prosthesis after a patient adapts to the new position relation, and verifying, fine-tuning and determining the beautiful requirements of the patient in the mouth of the patient. However, the conventional procedure described above has the following problems:
First), the occlusal plate in the traditional process has larger volume, no tooth appearance, poor aesthetic property, strong foreign body sensation of patients and low wearing willingness. At the same time, the bite plate needs to be worn for at least 12 hours every day, which brings great inconvenience to patients.
Second), the patient also needs to replace the diagnostic prosthesis after adapting to the bite site, communicate with the physician and then determine the anterior tooth profile. The need to replace the diagnostic prosthesis again if the aesthetic effect is not satisfactory increases the number of re-diagnoses of the patient, the working time of the oral technician and the oral physician, and increases the medical expenditure.
Third), in the traditional process, there are at least two transfer processes of the occlusion relationship, the patient goes through the transition from the occlusal pad to the diagnostic prosthesis and then from the diagnostic prosthesis to the final prosthesis, each time the record and transfer of the occlusion relationship are increased, the deviation of the position record of the final prosthesis is reduced, and the number of times of the re-diagnosis and the total time of the visit of the patient are increased.
Fourth), the traditional procedure is a semi-digitizing process, and transferring the already adapted bite plate relationship in the patient's mouth to the diagnostic prosthesis also increases the errors of the digitizing procedure, negatively affecting the accuracy of the final prosthesis.
Fifth), conventional diagnostic prostheses (temporary prostheses) require dental preparation procedures on patients, and many patients fear of grinding teeth, resulting in discontinuation of the bite reconstruction procedure before the diagnostic prostheses are worn after the bite plate treatment, requiring a simple, easy-to-wear, less damaging diagnostic prosthesis to give the patient sufficient confidence to enter the subsequent treatment session.

Detailed Description
The application will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present application and are not intended to limit the scope of the present application. Furthermore, it should be understood that various changes and modifications can be made by one skilled in the art after reading the teachings of the present application, and such equivalents are intended to fall within the scope of the application as defined in the appended claims.
Referring to fig. 1, the method for manufacturing a diagnostic prosthesis for full-process digital intelligent occlusion reconstruction disclosed in this embodiment specifically includes the following steps:
Step1, collecting intraoral and extraoral data of a patient, including but not limited to: facial scan data, upper and lower dentition, bite data, and bite relationship recorded by electronic facebow, CBCT data (including but not limited to patient alveolar bone and tooth data recorded by CBCT).
Step 2, designing and recording a new occlusion relationship by adopting various conventional medical means known to a person skilled in the art based on the intraoral data and the extraoral data of the patient acquired in the step 1.
Step 3, in digital software commonly used by those skilled in the art, teeth are arranged in the new occlusion relationship recorded in step2 by using a tooth database.
In this embodiment, the aforementioned digitizing software commonly used by those skilled in the art includes, but is not limited to, conventional oral digitizing software such as 3shape, exocad, planmeca.
When teeth are arranged in a new occlusion relationship, the static function requirement, the dynamic function requirement and the aesthetic requirement need to be met, and the specific logic is as follows:
1) Static functional requirements:
The need for diagnostic prostheses to meet functional requirements in the static state is primarily referred to as the correct in-plane slope. The abnormality of the occlusal inclination is related to occurrence of dentition abrasion and distribution of abrasion, and the occlusal inclination is designed in a targeted manner in order to achieve a state of functional and structural harmony, wherein: patients with excessive occlusal inclination are prone to posterior tooth wear, and the occlusal inclination needs to be reduced; patients with too small a occipital slope are prone to anterior tooth wear, requiring an increase in occipital slope.
After determining the treatment plan, the doctor and technician can design an occlusal slope at an angle of about 15 degrees to the orbital auricular occlusal plane (FH occlusal plane) based on the CBCT data of the patient, bisect the interocclusal distance and design a prosthesis to restore the patient's occlusal plane.
2) Dynamic functional requirements:
The need for a diagnostic prosthesis to meet the functional requirements under dynamic conditions mainly means that the prosthesis is able to function correctly during dynamic occlusion, including correct lateral and anterior movements. The lateral movement is designed into double-sided group tooth function or cuspid guiding combination: refers to the uniform contact (group tooth function fit) of upper and lower teeth of the working side and the contact (cuspid guide fit) of upper and lower teeth of the working side when the mandible is engaged laterally, and the non-working side upper and lower rear teeth are not contacted. The physician can simulate the patient's bite with computer aided design software using the above-described acquired digitized information. During simulation, doctors and technicians can achieve the desired dental occlusion by observing the prosthesis in the dynamic occlusion and virtual occlusion frames, adjusting the prosthesis shape, slope, contact points.
The reasonable forward extension movement means that when the mandible is in forward extension movement, the functions of the upper front teeth and part of the cuspids play a role in guiding the lower front teeth, and the rear teeth are separated from occlusion contact, so that occlusion interference of the rear teeth is avoided, and protection of the mandible is realized. If the posterior teeth are contacted when the mandible is extended forwards, the posterior teeth are subjected to lateral force, periodontal damage occurs, and related injuries of temporomandibular joints, such as excessive contraction of masticatory muscles, abrasion of condyles and the like, are caused. Therefore, in the process of designing the prosthesis, the rear teeth have stable contact at multiple points when the tooth tips are staggered, and coordinate with the condyloid slope after the cutting slope and the tooth tip slope are determined, so that the tooth tip height is ensured, and the rear teeth are separated from occlusion contact when the front teeth are engaged. In order to achieve the aim, the personalized occlusion parameters of a patient are obtained through the electronic facial arch, and the mandibular function movement track of the patient is digitally reproduced by utilizing the virtual combination frame in software, so that the tooth morphology and occlusion are adjusted, and complications possibly occurring in occlusion reconstruction are avoided.
3) Aesthetic requirements:
Bite reconstruction includes aesthetic reconstruction in addition to functional reconstruction. Tooth morphology, size, location and arrangement designed to meet aesthetic criteria are targets for aesthetic reconstruction. Analysis of a patient's face, i.e. "face guidance", is critical to personalized aesthetic repair. The 4 important factors affecting anterior tooth aesthetics are incisor edge position in the upper jaw, clinical crown length ratio, gingival margin position and upper anterior tooth width ratio. It is worth noting that in addition to the coordination of gums and teeth, the profile of the anterior teeth needs to be adapted to the contours of the patient's face, lips, etc. In the traditional method, doctors carry out aesthetic reconstruction design after obtaining data through the ways of observing the face of a patient, taking out-of-mouth pictures, preparing research models and the like. In the invention, the face of a patient is scanned to obtain a maxillofacial digitized model, and simultaneously, the intraoral scanning is performed to obtain a dentition digitized model. And combining the CBCT data of the jaw of the patient, and registering in software to reproduce the three-dimensional structure of the jaw face of the patient. Therefore, the front tooth aesthetics can be more intuitively and comprehensively designed, and communication with a patient in terms of final aesthetic restoration effect is facilitated.
Step4, designing a segmented diagnostic prosthesis in digital software according to the occlusion relation determined in the step 3, and further comprising the following steps:
And step 401, setting the positioning direction of the diagnostic prosthesis and drawing outline high-point lines on the residual teeth by following the design principle of the removable partial denture and forming a certain included angle with the dislocation force direction, utilizing a tooth database to arrange 17, 16, 15 and 14 teeth under the occlusion relation determined in the step 3, determining new model data, performing spatial subtraction on the new model data and the original tooth data by using Boolean operation, generating new empty shell tooth socket data, comparing the new empty shell tooth socket data with the outline high-point lines after generating the new empty shell tooth socket data, if the edge of the new empty shell tooth socket data is in the outline high-point line crown direction, not processing the new empty shell tooth socket data, and if the edge of the new empty shell tooth socket data is in the outline high-point line gingiva direction, taking the outline high-point line as the edge, and selecting the edge thickness to be 0.5-1mm, thereby obtaining the 17, 16, 15 and 14 tooth position diagnostic prosthesis digital model.
Step 402, the method described in step 401 is repeated 5 times to prepare 13, 12, 11, 21, 22, 23 dental diagnostic prosthesis digital models, 24, 25, 26, 27 dental diagnostic prosthesis digital models, 34, 35, 36, 37 dental diagnostic prosthesis digital models, 33, 32, 31, 41, 42, 43 dental diagnostic prosthesis digital models and 44, 45, 46, 47 dental diagnostic prosthesis digital models, respectively, and finally obtain six-segment diagnostic prosthesis digital models as shown in fig. 2.
And 5, directly manufacturing the six-section diagnostic prosthesis according to the six-section diagnostic prosthesis digital model obtained in the step 5, or printing the six-section diagnostic prosthesis digital model obtained in the step 5, and manufacturing the six-section diagnostic prosthesis by using manufacturing methods well known to those skilled in the art such as silicone rubber turnover mould and the like by adopting an additive adding or material subtracting method, as shown in fig. 3.
And 6, fitting and fine blending in the mouth, and cementing the diagnostic prosthesis, wherein the wearing effect is shown in figure 4.
The invention divides the diagnostic prosthesis into six sections, and determines the edge of the prosthesis according to the contour of the dented dentition, has the advantages of ensuring that the interior of the prosthesis has no undercut, being capable of being positioned in the straight joint, simultaneously having retention force in the direction of disengaging from the occlusal position, and improving the retention rate of the prosthesis in the mouth.
