Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planning method for implanting a healing abutment for implant, a computer program for the same, and a recording medium for the implantable healing abutment,

The present invention relates to a planning method for mounting a healing abutment for an implant, and a computer program for the same, and more particularly to a computer program and a recording medium thereof for improving the convenience and accuracy of a procedure when a healing abutment is mounted on an alveolar bone in an implant procedure And a computer program and a recording medium therefor.

In the past, artificial crowns, bridges, interlocking partial dentures, or whole dentures were used to restore the teeth when they were removed. Recently, the use of implants has been spreading due to inconveniences in their use.

An implant is a dental prosthesis that fixes an artificial tooth by placing a fixture on or in the jawbone for the purpose of restoring a missing tooth.

An example of a conventional general implant procedure is as follows.

A fixture (artificial root) is placed through the surgical procedure to the alveolar bone of the patient, and the alveolar bone has an adhesion period of several weeks to several months to make the alveolar bone attach to the alveolar bone.

Thereafter, the gums are cut so that the abutment of the desired shape can be fitted to the oral environment of the patient, and a healing abutment for forming the gums according to the desired type of abutment is mounted, It has a gum recovery period of about two weeks.

Subsequently, an abutment to be used with the crown is prepared in a laboratory, or it is mounted in the mouth, or an abutment made of a ready-made article is mounted, and an upper prosthesis made in a laboratory is mounted on the abutment mounted.

In this process, the healing abutment provides the effect of stabilizing the gum and protecting the space inside the gum to prevent bacteria from penetrating into the gum or alveolar bone.

Conventionally, a conventional healing abutment has a slender cylindrical body shape. However, there is a problem that a gap is formed between the outer circumferential surface of the abutment and the gum line after being attached to the fixture, and bacteria are infiltrated through the gum . In particular, since the internal space of the extracted gums has various sizes and shapes depending on the shape of the extracted teeth, there is a problem in that the single space of the abutment which does not take this into consideration does not sufficiently protect the internal space of the gum.

As a conventional technique that takes this into consideration, Korean Registered Patent No. 10-1164444 (registered on July 04, 2012) has been proposed. In the conventional technique, the shape of the head portion of the abutment is formed corresponding to the internal space of the extracted gum, so that the gum can be covered, thereby protecting the internal space of the gum or jawbone and preventing the bacteria from penetrating into the internal space Implant assemblies are proposed.

However, even with the use of the above-described conventional techniques, there is a problem in that the fixture (primary procedure) and the adhesion period of several weeks to several months, the incision period of the gums, the healing abutment attachment (secondary procedure), and the period of gum restoration, The implant process is not significantly different from that of the previous one. Therefore, the patient experiences inconvenience due to various procedures and has suffered from pain due to incision of the gingiva several times.

For example, the functions of the data input unit 1150, the dental image data processing module 1102, and the fixture data processing module 1104 correspond to these functions. These known commercial products generally provide a fixture placement simulation function for the alveolar bone, and provide a fixture placement simulation function using a known surge guide.

3 is an exploded perspective view of a healing abutment model according to an embodiment of the present invention.

The healing abutment 100 applied to the present embodiment is integrally joined to the fixture 300 placed on the alveolar bone using the coupling screw 200. The model of the same shape and size as the real object is a healing abutment The input is set in the library.

The healing abutment 100 includes a head 106 having a main body shape of a temporary tooth, a coupling section 102 having a narrow cross section inserted into the coupling hole 304 of the fixture 300 to form a coupling state, An extension part 108 connecting the head 106 and the coupling part 102 and a coupling nut 200 formed in the fixture 300 through the coupling screw 200, The through hole 104 is provided.

The extension portion 108 has a sectional shape in the form of a superimposed light beam and is fixed to the inner surface of the extraction groove 25 formed in the gum 20 through the shape, 300 may be coupled to a healing abutment 100.

The head 106 has a rectangular planar shape and may be rounded to a portion of its edges and / or sides for ease of patient use.

The fixture 300 is inserted into the alveolar bone 10 through the screw portion 302.

The coupling screw 200 includes a screw head 206 having a driver hole 204 formed thereon and a fixture engaging screw portion 202 integrally formed under the screw head 206.

The planning method for mounting the healing abutment for the implant of the present embodiment will be described below. The planning method of this embodiment is implemented in the computing means 1000 described above.

FIG. 1 is a perspective view showing a state in which an implant fixture is placed at a missing tooth site, FIGS. 2a and 2b are a plan view schematically showing an extraction groove in a missing tooth region, and FIG. 5 is another cross-sectional view of a head portion of a healing abutment model according to an embodiment of the present invention, and Fig. 6 is another cross-sectional view of a head portion of a healing abutment model according to an embodiment of the present invention .

In step S1, dental image data representing the structure of the teeth and the gums 20 is obtained. The dental image data includes the shape data of the alveolar bone 10, the shape data of the gum 20, and the missing tooth state data to which the fixture 300 is to be placed. 9 is an exemplary view of a screen displaying dental image data of a patient, showing the structure of a tooth and a gum 20 of a patient in need of an implant procedure.

The missing tooth state data can be obtained by obtaining the data of the missing tooth shape data (including the root portion) and the portion of the missing tooth contacting the gum (corresponding to the extraction groove) in the state where the missing tooth has not yet been extracted, The shape data of the groove may be obtained.

In the step S2, among the models of the healing abutment 100 included in the library of the healing abutment 100 previously entered and set based on the dental image data and the position and orientation data of the fixture 300, A mounting review model having a head 106 of a size close to the size of the region 30 is selected.

More specifically, the selection of the mounting review model is based on whether the size of the head 106 of the model of the healing abutment 100 is included in a predetermined proximity condition compared to the size of the defect region 30 .

For example, when the size of the defect region 30 is 5 mm, the close range condition may be set to 4.8 to 5.2 mm, and the healing abutment 100 model included in the healing abutment 100 library A model in which the size of the head 106 is included in the close range condition may be selected as the mounting review model.

For example, the proximity condition may be set to 4.8 to 5.0 mm, which is smaller than the size of the defect region 30, but is not necessarily limited to a size smaller than the defect region 30 because the patient's tooth condition differs from person to person .

The healing abutment library of the present embodiment includes two or more healing abutment models having the same shape and size as the actual healing abutment, and each healing abutment model includes a head size, a head height, The hearing abutment library is set to have different values for at least one of the elements.

Figures 4 to 6 illustrate these various shapes and sizes of healing abutments. Figs. 4 to 6 correspond to sectional views taken along the line S-S 'of Fig.

4 illustrates two or more models in which the eccentricity (difference between d1 and d2) of the engaging screw hole 104 is different from each other. The model is configured so that the eccentricity becomes larger as the position of the head 106 moves from (a) to (c) with respect to the center line C of the engaging screw hole 104. For example, when the fixture 300 is placed at a slightly eccentric position rather than at the center of the defect region 30 according to the alveolar bone condition, the case where the model (b) or (c) .

Figure 5 illustrates two or more models with different head heights h. The model is configured such that the height of the head 106 decreases from (a) to (c) with respect to the upper end (the portion where the extension portion and the head meet) of the extension portion 108. [ For example, the model (b) or (c) may be mounted instead of the model (a) so that the top of the healing abutment does not become higher than the adjacent value depending on the height of the adjacent teeth (2,4) .

Figure 6 illustrates two or more models with different head sizes (D1). The model is configured such that the width of the head 106 becomes smaller from (a) to (c). For example, the model (b) or (c) may be mounted instead of the model (a) so that the head of the healing abutment is matched to an appropriate size depending on the size of the missing or defective area 30.

The implant practitioner using the planning of the present embodiment selects a suitable model among the plurality of models in advance as a placement review model through a simulation process in consideration of various states of missing teeth of the patient, It can be determined as a mounting model and applied to an actual operation.

That is, according to the planning of the present embodiment, the conventional implantation process that involves fixture placement (primary procedure) and adhesion period of several weeks to several months, incision of the gums, attachment of healing abutment (secondary procedure) , The simulation of the planning process is used to select and determine the healing abutment with the shape and size closest to the patient's extraction groove in advance, and the combination of the fixture placement and the healing abutment together with the extraction of the missing tooth There is an advantage to be done.

On the other hand, the placement position and orientation data of the fixture 300 are determined based on the dental image data. 10 is an exemplary view showing a process of setting a position and orientation data of a fixture based on dental image data of a patient.

For example, the orientation and position of the fixture are determined such that the computing means three-dimensionally computes a range in which drilling is possible based on the inputted dental image data, and a user who executes the planning method using the computing means, (The center line of the fixture model in Fig. 10) in the fixture setting direction line. The drillable range can be calculated by taking into consideration spatially the interference with the adjacent teeth of the missing tooth, the risk of nerve damage, and the like. It is also possible that the optimum fixture placement direction and position are automatically set by the computing means. Further, the orientation and position of the fixture may be set together with a simulation of a known surge guide.

The data of the present embodiment including dental image data is basically provided in the form of three-dimensional spatial data, and can be displayed as a two-dimensional sectional image if necessary.

The size of the missing area 30 of the missing tooth may be defined as the area of the rectangular inner area surrounding the outermost point of the extracted tooth 25 of the missing tooth. The rectangular shape can be understood as a rectangle enclosing the extraction groove 25 while inscribing the extraction groove 25 in a state where the extraction groove 25 is viewed from above.

Preferably, the head 106 of the healing abutment used in this embodiment has a rectangular planar shape. In view of ease of use, the actual healing abutment head 106 may have a rectangular planar shape with rounded corners and / or sides. However, in the planning method of the present embodiment, when the size information of the head 106 is used, it is possible to calculate or define the size, area, and side length by considering it as a rectangle in which the rounding process is not performed.

The head 106 of the healing abutment of the present embodiment should have a shape covering the extraction groove 25 when mounted on the fixture 300. [

In consideration of this point, the defect region 30 of the present embodiment has a rectangular shape having a rectangular area having a flat surface area covering the extraction groove 25, and has a healing aberration suitable for the extraction groove 25 into which the implant is to be placed. Reference information for selecting the user < RTI ID = 0.0 > 100 < / RTI > In view of this point, the defect region 30 of the present embodiment is defined as a rectangular inner region surrounding the outermost point of the extraction groove 25 of the missing tooth.

Such a defective area 30 is illustrated in Figs. 2A and 2B. 2A shows a rectangular shape, and FIG. 2B shows a rectangular shape obtained by rounding.

Whether or not the model of the healing abutment 100 covers the extraction groove 25 and whether or not the model of the healing abutment 100 is in conflict with the adjacent teeth 2,4 of the extraction groove 25 The defect region 30 is not necessarily defined as a rectangle. For example, the size of the missing area 30 of the missing tooth is defined as the area of the inner area of the drawn shape surrounding the outermost point of the extraction groove 25 of the missing tooth, An elliptical shape, or the like) is set in advance, it can be used as a figure of the present embodiment.

As another example, the size of the defect region 30 of the missing tooth does not necessarily surround the outermost point of the extraction groove 25 of the missing tooth, but surrounds the outermost point of the extraction groove 25 of the missing tooth, for example May be defined as the area of the internal area of the figure corresponding to the equal range (for example, 95%) preset for the rectangle. Since the shape of the extraction groove 25 is irregular for each patient, when the extraction groove 25 is excessively eccentric or protruded in one direction, it is possible to set the size of the defect region 30 in this manner.

As another example, the size of the defect area 30 of the missing tooth may be defined as the length w of the rectangular defect direction side surrounding the outermost point of the extraction groove 25 of the missing tooth. Referring to FIG. 2, the length w of the side of the defect direction can be understood as the length of the side of the side of the defect region 30 in the direction of connecting between the adjacent sides.

The size of the head 106 is defined as either the area or width seen in the planar direction of the head 106. The width of the head 106 (D1 in Fig. 6) is set to be shorter than the width of the head 106 in the fixture 300 in the sides of the rectangular head 106 seen in the planar direction It can be understood as the length of the side in the direction in which the two side adjacent teeth are connected in the installed state.

For example, in the step S2, the selection of the mounting review model may be performed by selecting a model of the healing abutment 100 mounted on the fixture 300, RTI ID = 0.0 > 106, < / RTI >

For example, when there are two or more models of the healing abutment 100 having the head 106 having a size close to the size of the missing area 30 of the missing tooth, A model of the healing abutment 100 having the head 106 lower than the height of the adjacent teeth 2,4 is selected as the mounting review model.

As described above, the model of the healing abutment 100 is provided so as to have different values with respect to at least any one of the head size, the head height, and the engaging screw hole eccentricity. For example, two or more healing abutment 100 models with the same head size but different head height or coupling screw hole eccentricity may be included in the library.

For planning, it is necessary to further determine which model should be selected as the mounting review model when there are two or more models of the healing abutment 100 having the head 106 of a size close to the size of the defect lacking region 30 . Further, when the healing abutment 100 is projected higher than the adjacent tooth in the fixture mounting state, the patient can feel a foreign body feeling.

In view of this, in the present embodiment, a model of the healing abutment 100 having the head 106 lower in height than the adjacent tooth 2, 4 of the missing tooth in a state of being mounted on the fixture 300, It is selected as a mounting review model.

7, a portion of the head 106 is exposed above the gum 20, with the healing abutment 100 mounted on the fixture 300. As shown in FIG. If a model of the healing abutment 100 having the height of the head 106 of a height close to the tooth is lower than the tooth height of the adjacent teeth 2,4 exposed on the gum 20 as the model of the fixture 300, A good temporary tooth usage state can be provided without feeling a foreign body feeling.

As another example, in the step S2, the selection of the mounting review model may be made based on whether or not the interference with the adjacent teeth 2,4 is generated in a state where the model of the healing abutment 100 is mounted on the fixture 300 Can be achieved.

For example, when there are two or more models of the healing abutment 100 having the head 106 having a size close to the size of the defect lacking region 30, 2 < 4 >) region and the hearing abutment 100 model in which interference does not occur is selected as the mounting review model. Whether or not the interference occurs is determined by whether the head 106 of the healing abutment 100 is overlapped with the adjacent tooth 2, 4 and the respective planar area (or side area) in the planar direction (or lateral direction) It can be judged by a method of confirming whether or not it conflicts. Preferably, the determination of whether or not the tooth is in contact is not limited to the tooth root, but is determined in consideration of the maximum wing portion.

Meanwhile, in step S2, the proximity range condition of step S2 may be calculated by applying a predetermined proximity range weight to the size of the defect area 30. [

For example, if the proximity weight is ± 1.1 and the size of the defect region 30 is 5 mm, then the proximity condition can be calculated to be 4.5 to 5.5 mm (= ± 1.1 * 5). As another example, if the near range weight is -1.05 and the size of the defect region 30 is 6 mm, the near range condition can be calculated to be 5.7 to 6.0 mm (= -0.05 * 1.05).

The above-described mounting review model selection process in step S2 may be accompanied by providing a display for the user.

In step S3, when the selected mounting review model is determined as the fixture 300 mounting model, the determined fixture 300 mounting model is displayed together with the dental image data.

The determination of the mounting model of the fixture 300 can be made by a method in which the user determines one final model for the mounting review model selected in step S2. Such an input determination may be an identification input for one selected model or a selection input for any one of two or more selected models.

For example, the determination of the fixture 300 mounting model in step S3 may include a step S31 of displaying the mounting review model selected in step S2, a step S32 of receiving a determination input on the display-provided mounting review model ). ≪ / RTI > This determination input can be made through a normal user GUI.

As another example, the determination of the fixture 300 mounting model in step S3 may include a step S301 of displaying the mounting review model selected in step S2 and a step S302 of determining whether the mounting review model is mounted on the fixture 300 A step (S302) of displaying an image in which the height and the height of the adjacent tooth (2,4) of the missing tooth can be compared with each other, and the step (S303) of receiving the determination input for the display provided mounting review model. This embodiment means that a decision can be made in consideration of the height comparison between the selected model and the adjacent value in the fixture mounting model determination process of step S3, apart from the above-described mounting review model selection of step S2.

As another example, the determination of the mounting model of the fixture 300 in the step S3 may include a step S3001 of displaying the mounting review model selected in the step S2 and a step S3001 of setting the mounting review model in the state where the mounting review model is mounted on the fixture 300 A step S3002 of displaying an image of whether or not interference with the adjacent teeth 2,4 is observed in the step S3003, and a step S3003 of receiving a decision input on the display-provided mounting review model S3003. This embodiment means that a determination can be made in consideration of the interference with the adjacent tooth in the fixture mounting model determination process in step S3, apart from the above-described mounting review model selection in step S2.

Meanwhile, in step S3, the determination model of the fixture 300 may be determined by automatically selecting the model as a fixture mounting model if the model is selected as the mounting review model in step S2.

As another example, the determination of the fixture 300 mounting model in step S3 may be performed by determining one model closest to the size of the defect area 30 as the fixture (30) when the mounting review model selected in step S2 is two or more 300) mounting model.

FIG. 7 is an exemplary view showing a state of a healing abutment model determined by a fixture mounting model together with dental image data according to an embodiment of the present invention, and illustrates such a display providing state.
