Description

Manufacturing method of guide plate and personalized titanium mesh installation method

Technical Field

The application relates to the field of oral implant bone increment technology, in particular to a guide plate manufacturing method and a personalized titanium mesh installation method.

Background

At present, personalized titanium mesh is commonly used in oral implant bone increment technology for accurately controlling bone increment. Among them, a collagen membrane (hereinafter collectively referred to as "barrier membrane") coated on a titanium mesh serves as a barrier such that a space for bone cell growth is formed between it and a bone defect area. Since the growth rate of epithelial cells and fibroblasts is faster than that of bone cells, the barrier membrane can also block the growth of epithelial cells and fibroblasts into the bone defect area.

In the related art, a doctor needs to make an adapted titanium mesh in a three-dimensional modeling manner according to the condition of a bone defect area of a patient before performing a bone augmentation operation on the patient. In order to mount the titanium mesh on the alveolar bone, a hole needs to be drilled on the alveolar bone of the patient to insert the fixture, and a fixture hole matching the titanium mesh needs to be designed when the titanium mesh is designed. The doctor needs to consider the positions of the nerves in the alveolar bone and the bone mass at each position in selecting the position where the fixture is driven.

However, it is difficult for a doctor to directly determine the position of a drilled hole in an alveolar bone during surgery, and since the titanium mesh is not completely fitted to a bone defect area, it is also difficult to directly determine the position of the titanium mesh, so that the drilled hole position deviates from an ideal position determined in a three-dimensional model, and especially when the drilled hole position touches a nerve, irreparable injury is caused to a patient.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In addition, the term "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In this context, unless otherwise specified, the term "/" generally indicates that the associated object is an "or" relationship.

Embodiments of the application are described in further detail below with reference to the drawings.

The embodiment of the application provides a manufacturing method of a guide plate, which is convenient for doctors to drill holes on alveolar bones of patients more accurately when performing bone incremental surgery, and the personalized titanium mesh is accurately arranged in a bone defect area in the oral cavity of the patients, so that deviation between the drilling position and an ideal position during drilling is avoided, and the surgery risk is reduced.

Specifically, the main flow of the method for manufacturing the guide plate provided by the embodiment of the application is described as follows.

As shown in fig. 1, 2 and 3:

Step S110: and obtaining an oral scanning model and an ideal jaw model.

Both the mouth scan model and the ideal jaw model are three-dimensional models. The oral cavity outline of the patient can be reflected by the oral cavity sweeping model, and the oral cavity outline can be obtained by scanning the oral cavity of the patient through the scanning equipment. The ideal jaw bone model is a model of the bone defect area of the patient after the alveolar bone is grown, and the establishment process is as follows:

step S210: CBCT data is acquired.

The CBCT data is CT data applied to the field of oral cavities, can reflect the width, thickness and height of alveolar bones of a patient, bone density, facial nerves, blood vessels, nasal sinus positions and the like, and can be obtained by scanning the oral cavity of the patient through CT scanning equipment.

Step S220: and matching the mouth scanning model with the CBCT data to obtain a matching model.

Because CBCT data can accurately reflect the oral cavity data of a patient, namely the width, thickness and height of the alveolar bone, bone density, facial nerves, blood vessels, sinus position, etc., the outline of the oral cavity structure is rather blurred. The mouth sweep model can just compensate for this deficiency. Therefore, the mouth scan model and the CBCT data can be matched, so that a matching model which can reflect the oral cavity structure of a patient more comprehensively is obtained.

In the application, the mouth scan model and the CBCT data are matched mainly by a three-point registration method. The three-point registration method realizes matching by determining key characteristic points such as adjacent tooth cusps, tooth sockets and the like in the mouth scanning model and CBCT data. The three-point registration method is a common technical means for those skilled in the relevant art, and thus, it is not described in detail herein.

Step S230: and determining tooth arrangement information according to the matching model.

The tooth arrangement information is the number and positions of the tooth bodies to be planted. The oral cavity structure of the patient can be displayed in the matching model, and a doctor can determine the bone defect area of the patient in the matching model, determine where to implant the dental implant, and further determine the number and the positions of the implanted dental implant.

It will be appreciated that the number, size and placement of the implants can be further determined only after the tooth placement information is determined.

Step S240: and determining the implant size, the implant position and the bone increment according to the matching model, the tooth arrangement information and the position relation between the bone increment and the implant.

It will be appreciated that a doctor implants a dental implant in a patient's bone defect area, first requiring the alveolar bone of the bone defect area to be intact, so that when the implant is fixed in the alveolar bone, the alveolar bone can provide sufficient bone mass to support the implant, and generally requires the bone augmentation to be able to encapsulate the implant. Therefore, it is important for a physician to determine the proper implant size and bone augmentation when performing a surgical planning. Generally, the larger the implant size, the better the implant size, and the larger the contact surface between the implant and the tooth body, so that the tooth body can be fixed more firmly. However, the larger the size of the implant, the more the bone augmentation is required, otherwise insufficient bone mass is provided. Of course, bone augmentation to a certain extent can also cause inconvenience to the patient's eating behavior.

Further, after the tooth arrangement information is determined, the planting range of each implant can be determined according to the tooth arrangement information, and the planting position is preferably located on the symmetry axis of the tooth body. When determining the implant size and the bone increment, the maximum amount of the bone increment can be determined preferentially, and then the implant size is determined according to the maximum amount of the bone increment and the position relation between the bone increment and the implant. Specifically, the positional relationship between the bone increment and the implant is 2-3mm for buccal bone mass, 1-2mm for lingual bone mass, and 1-4mm for alveolar ridge parietal bone mass. Wherein, the buccal bone mass is the bone mass of the implant facing the cheek side, and the lingual bone mass is the bone mass of the implant facing the tongue side.

Step S250: and adding a bone increment model into the matched model to obtain an ideal jaw model.

And adding a bone increment model to the bone defect area in the matched model, so that the alveolar bone in the bone defect area is also the complete alveolar bone in the presented model, namely the ideal jaw bone model. The bone increment model is the part which is matched with the bone defect area and can form the complete alveolar bone.

Step S120: a first coverage is determined in the ideal jaw model.

The first coverage surface is a titanium mesh model coverage surface, and the surface of the bone increment can be selected from the ideal jaw model as the first coverage surface.

Step S130: and performing first treatment on the first coverage surface to obtain a titanium mesh model.

In making a titanium mesh model, it is necessary to fill the first coverage surface with titanium mesh cells. And 3D printing is carried out on the titanium mesh model, and the titanium mesh can be obtained.

It will be appreciated that in designing a titanium mesh model, it is necessary to provide retention holes in the titanium mesh model for securing the titanium mesh. In determining the retention holes, it is necessary to avoid important locations in the alveolar bone such as nerves, facial nerves, sinuses, etc., and there is also a requirement for bone mass at the selected locations. Thus, the physician needs to empirically determine the appropriate retention hole location in the three-dimensional model. Since CBCT data can reflect information of the width, thickness and height of the patient's alveolar bone, bone density, facial nerves, blood vessels, sinus position, etc., a doctor can determine an appropriate location to install the fixture. After the doctor determines the position of the alveolar bone for inserting the retention pin in the three-dimensional model, the first cover surface and the titanium mesh model can determine the position of the retention hole corresponding thereto.

Step S140: a second coverage is determined in the mouth scan model.

The second covering surface is an adjacent tooth covering surface. The second cover surface includes a first side cover surface and a second side cover surface. The first side covering surface is the covering surface of adjacent teeth on one side of the bone defect area, and the second side covering surface is the covering surface of adjacent teeth on the other side of the bone defect area. When the first side cover surface and the second side cover surface are selected from the three-dimensional model, the first side cover surface and the second side cover surface need to be made into shapes which are fit with teeth, so that the manufactured guide plate can accurately determine the positions of the fixture nails. The thickness of the first side covering surface and the second side covering surface is 0.1 mm-0.5 mm. It should be noted that, because the mouth scan model can reflect the mouth contours more clearly, the second coverage obtained using the mouth scan model is also more accurate.

Step S150: and performing second treatment on the first coverage surface and the second coverage surface to obtain a guide plate model.

It will be appreciated that a guide plate made from a guide plate model can help a physician better locate the fixture on the alveolar bone. The guide plate model comprises a first covering surface, a second covering surface and a position relation between the first covering surface and the second covering surface.

The manufacturing process of the guide plate model is as follows: first, the first coverage area and the second coverage area are combined. And then, connecting the first coverage surface with the second coverage surface by using a plurality of connecting rod models.

Because the first covering surface and the second covering surface are two independent covering surfaces, in order to determine the position of the fixing nail according to the adjacent tooth position of the patient, the position relation between the first covering surface and the second covering surface which conform to the oral cavity structure of the patient needs to be established. Thus, it is necessary to combine the first cover surface with the second cover surface and determine the positional relationship of the first cover surface and the second cover surface. Because the first coverage is the coverage of the titanium mesh model, the design model is derived from CBCT data; the second coverage is an adjacent tooth coverage, the design model is derived from the mouth sweeping model, and the matching of the CBCT data and the mouth sweeping data is completed in step S220, so that the positional relationship between the first coverage and the second coverage and between the first coverage and the second coverage obtained according to the matching model is the positional relationship between the first coverage and the second coverage which conform to the oral cavity structure of the patient.

Further, in order to enable the positional relationship between the first cover surface and the second cover surface to be maintained, it is also necessary to connect the first cover surface and the second cover surface by a plurality of connection bars. In the application, six connecting rod models are arranged, and the connecting rod models can be cylindrical or other geometric shapes. In the implementation of the present application, in order to distinguish six connecting rod models, they are named as a first connecting rod model, a second connecting rod model, a third connecting rod model, a fourth connecting rod model, a fifth connecting rod model and a sixth connecting rod model in order.

One end of the first connecting rod model is connected with the first side covering surface, and the other end of the first connecting rod model is connected with the second side covering surface, so that the position relation between the first side covering surface and the second side covering surface is fixed. And then, one end of the second connecting rod model is connected with the circumference of the first connecting rod model, and the other end of the second connecting rod model is connected with the first covering surface so as to preliminarily fix the position relationship among the first covering surface, the first side covering surface and the second side covering surface. And one end of the third connecting rod model and one end of the fourth connecting rod model are respectively connected with the first side coverage surface, and the other end of the third connecting rod model and the other end of the fourth connecting rod model are respectively connected with the first side coverage surface. And similarly, one end of the fifth connecting rod model and one end of the sixth connecting rod model are respectively connected with the second side coverage surface, and the other end of the fifth connecting rod model and the other end of the sixth connecting rod model are respectively connected with the first coverage surface so as to further strengthen the position relationship among the first coverage surface, the first side coverage surface and the second side coverage surface.

It is worth to say that, in the guide plate model, the observation holes are formed in the positions, corresponding to each tooth, on the surface of the second covering surface, so that when the guide plate is installed in the oral cavity of a patient, a doctor can observe the guide plate through the observation holes to confirm the fitting degree of the guide plate with the teeth of the patient, and confirm whether the guide plate is installed in place. In the application, the observation hole is a square hole or a rectangular hole, and the observation hole is positioned at the crown high point of the adjacent tooth.

Step S160: and processing the titanium mesh model and the guide plate model according to Boolean operation to obtain a guide plate model, and performing 3D printing.

The boolean operation can remove unwanted portions of the three-dimensional model. Boolean operation is a common technical means for those skilled in the relevant arts, and will not be described in detail herein.

In order to better judge the fit and the in-place condition of the manufactured guide plate and the teeth, a transparent resin material is required to be used when the guide plate is manufactured by 3D printing.

Fig. 4 is a diagram illustrating a personalized titanium mesh installation method according to an embodiment of the present application.

The guide plate manufactured according to the manufacturing method of the previous embodiment can assist doctors in determining the drilling position of the alveolar bone during the bone augmentation operation, so that the personalized titanium mesh can be installed.

The main flow of the personalized titanium network using method provided by the embodiment of the application is described as follows.

As shown in fig. 4:

Step S310: after bone powder is filled into the bone defect area, the guide plate provided with the reference hole is fixed in the oral cavity through the residual natural teeth, so that the surface of the guide plate where the reference hole is positioned is attached to the alveolar bone.

It can be appreciated that when a patient suffers from a car accident or other accident, a plurality of dental sites are continuously or intermittently missing and various types of large-area jawbones are missing, the alveolar bone is gradually degraded due to the fact that the alveolar bone in the bone defect area loses the force with the teeth. However, in order to implant a dental implant into a patient, it is first necessary to allow the alveolar bone of the bone defect area to continue to grow so that the bone mass reaches a certain level to support the implant. After filling bone powder into the bone defect area, the alveolar bone of the bone defect area can realize continuous growth.

Since the growth rate of epithelial cells and fibroblasts in the oral cavity is faster than that of bone cells, it is necessary to provide a barrier membrane on the bone defect area to block the growth of epithelial cells and fibroblasts to the bone defect area. The barrier membrane comprises a personalized titanium mesh and a collagen membrane coated on the titanium mesh. Wherein, the titanium mesh is used for forming a space for bone cell growth between the titanium mesh and the bone defect area, and the collagen membrane is used for blocking epithelial cells and fibroblasts. In summary, it is necessary to provide a titanium mesh.

The doctor is fixed to the alveolar bone through the retention holes of the titanium mesh when the titanium mesh is mounted on the alveolar bone. The guide plate is used to locate the retention holes on the alveolar bone prior to installation of the titanium mesh. The guide plate is provided with a reference hole in advance. When the guide plate is fixed in the oral cavity, the doctor can determine the position of the retention hole on the alveolar bone by referring to the position of the hole. Wherein, the guide plate is also provided with a structure for wearing the guide plate in the oral cavity. Because the position relation between the structure for wearing on the guide plate and the reference hole corresponds to the position relation between the position where the guide plate can be worn in the oral cavity of the patient and the bone defect area, when the guide plate is fixed in the oral cavity of the patient, the position of the reference hole on the guide plate on the alveolar bone is the position for fixing the retention nail. When the surface of the reference hole on the guide plate is attached to the alveolar bone, the position for fixing the fixture is determined more accurately.

Step S320: drilling holes in the alveolar bone according to the positions of the reference holes.

Because the same three-dimensional model is used when the guide plate and the titanium mesh are manufactured, when a doctor accurately determines the position of the retention hole in the three-dimensional model, the doctor can accurately drill the alveolar bone according to the position of the reference hole, the drilling position is accurate, deviation between the drilling position and an ideal position can be avoided, nerves on the alveolar bone are avoided, and therefore the operation risk is reduced.

Step S330: and removing the guide plate.

Step S340: the titanium mesh is placed over the alveolar bone and the retention holes are aligned with the holes in the alveolar bone.

Step S350: the retention pin is inserted through the retention hole and is locked into the hole in the alveolar bone.

Compared with the method that a doctor directly drills holes on the alveolar bone according to the titanium mesh, the method has higher accuracy and can reduce the risk of operation.

The above description is only illustrative of the preferred embodiments of the present application and of the principles of the technology employed. It will be appreciated by persons skilled in the art that the scope of the application is not limited to the specific combinations of the features described above, but also covers other embodiments which may be formed by any combination of the features described above or their equivalents without departing from the spirit of the application. Such as the above-mentioned features and the technical features having similar functions (but not limited to) applied for in the present application are replaced with each other.
