Description
Technical Field
The invention relates to the technical field of false teeth, in particular to a removable false tooth abutment tooth preparation and implant implantation combined guide plate and a manufacturing method thereof.
Background
The tooth free end loss is one of the common dentition loss types in clinical medicine, namely the retention of front teeth and the loss of back teeth, and because of the particularity of the tooth loss part, Removable Partial Dentures (RPD) are traditionally adopted for repair, and because the tail end of the tooth is lack of natural teeth or bone support structures for supporting or retaining the removable partial dentures in the repair process, the alveolar ridge and mucosa in the tooth loss area are greatly stressed and are obviously absorbed quickly.
After the conventional removable partial denture is repaired, a support of the removable partial denture is put on the natural teeth to play a part of supporting role for the removable partial denture, and a snap ring on the removable partial denture is clamped on the natural teeth to prevent the denture from falling off, which is called as retention. Meanwhile, the removable partial denture can be prevented from falling off, which is called retention. Meanwhile, the denture fixing device also plays a role in preventing the denture from shaking, and is called as stabilization. However, the partial denture with the removable free end inevitably sinks and swings unstably, and certain damage can be caused to the abutment through the clamping ring.
In order to improve the situation, an implant is implanted at the free end, implant assistance is added for the traditional RPD, the implant is connected with the RPD by using an attachment, and the free end is converted into a non-free end. According to the difference of the design position of the implant, the unattractive snap ring can be eliminated, the bad dental arch form can be improved, compared with the pure implantation fixation repair, the number of the implant is reduced, and the economic burden of the patient is greatly relieved.
However, at present, the implantation auxiliary removable partial denture repairs the free end dentition defect, and the preoperative unified planning of the RPD design and the implant implantation is lacked, so that the problems of the removable denture in-place way, the position-fixing undercut and the like are not fully considered in the implantation, so that the RPD design and the implant implantation have larger problems, and firstly, when the RPD is brought in and taken out along the abutment in-place way direction, the operation of different angles is presented between the male and female parts of the implant attachment, and the transitional abrasion of the male and female parts is caused; secondly, the RPD can not be smoothly and passively put in and taken out due to the influence of the angle of the implant, and overlarge lateral force can be caused to the abutment in the two processes; the third problem is that an angle exists between the axial direction of the implant and the direction of the occlusal force, so that the implant is subjected to larger lateral force, and the peripheral alveolar ridge is easy to absorb, even to loosen and fall off prematurely and the like.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a removable denture abutment tooth preparation and implant implantation combined guide plate and a manufacturing method thereof, which can uniformly plan the related information of the removable denture natural teeth and the implant information and effectively and accurately solve the contradiction caused by the completely separated traditional removable denture design and abutment tooth preparation and implant operation.

and 4, step 4: the removable denture abutment preparation and implant combined guide plate three-dimensional model is generated by a computer and is printed by 3D resin, and the removable denture abutment preparation and implant combined guide plate can be obtained.
Compared with the prior art, the invention has the beneficial effects that:
1) the removable denture abutment preparation and the implant implantation are planned in a unified way by the combined guide plate manufactured by the manufacturing method and embodied in the same guide plate form, firstly, when the RPD is put in and taken out along the abutment in-place way, the male and female parts of the implant attachment can move mutually without a cross angle, and the abrasion among the parts is reduced to the maximum extent; secondly, the false tooth and the implant attachment can be in the same dislocation direction, the RPD can be in place and taken out smoothly and passively, the abutment cannot be subjected to large lateral force in the two processes, finally the axial direction and the occlusal force direction of the implant can be coordinated as much as possible, the degree of the implant subjected to the lateral force is reduced, the absorption of the marginal alveolar ridge is slowed to the greatest extent, and the service life of the implant is ensured. Effectively and accurately solves the problems caused by the complete separation of the traditional removable denture design and the abutment preparation and implantation operations.
