Description
Technical Field
The utility model belongs to the technical field of oral cavity digitization, and particularly relates to a preparation guide plate and a removable partial denture support.
Background
In the field of oral medicine, dentition defects are one of the most common oral diseases. Repair is usually performed using a fixed bridge, removable partial dentures, or implant dentures. Fixed bridge dentures have low patient acceptance due to the need to abrade a large amount of healthy dental tissue. The removable partial denture has the advantages of low cost, micro-wound, wide adaptation, and the like, and is widely applied. However, due to the structural characteristics, it is necessary to design a snap ring, a bracket, etc. on the remaining teeth to improve the overall retention and stabilization effects. Therefore, the remaining teeth are subject to great stress during use, which affects their health. Secondly, in the patient population with more missing teeth, the removable partial denture can not be well retained and stabilized due to poor conditions of the remained teeth, and the using effect is greatly reduced.
In view of the above, for a patient with a lot of missing teeth, it is considered that a small number of implants (1-2) are implanted in the missing tooth area, then a metal bracket type removable partial denture (composed of a removable denture bracket and a defective area artificial tooth) is manufactured, and then the removable partial denture is fixed on the upper part of the implant by stably combining the anode structure of the upper abutment (mainly including a magnet, a locator, a ball cap, etc.) of the implant with the cathode structure of the abutment in the reserved space of the removable partial denture base area. Thus, the partial false tooth can be removed, and good stability and retention can be obtained through the abutment structure, and the effective function of the false tooth is ensured; meanwhile, the implant also provides good support, and the absorption of alveolar bone is slowed down. The implant has the advantages of good retention effect of the implant and moderate price of the removable partial denture, and is also called as an implant support type removable partial denture clinically.
At present, use clinically to prepare the baffle and carry out the implantation of implant, ensure when carrying out the implant nest hole and prepare, can go on according to predesign to avoid important blood vessel and nerve in the alveolar bone, prevent the damage. Common fabrication methods are manual simple guides and digitally designed/fabricated guides.
However, in practical use, it is also found that, when the bracket type removable partial denture is manufactured, a guide plane is prepared on the residual natural teeth; due to the lack of practical reference, the doctor can only complete the grinding of the pilot plane or the implantation of the implant by means of two-dimensional image photographs or approximate impressions, and as a result, the orientation of the stented removable partial denture in the implant path differs from the implant implantation orientation. After the removable denture is used for a period of time, the parts connected with the abutment of the base plate of the removable denture are seriously worn, the retention effect of the removable partial denture is seriously influenced, and meanwhile, the implant can be subjected to larger lateral force due to the fact that the picking direction (the in-place direction) of the denture is not consistent with the implantation direction of the implant in the long-term removing and wearing process of the removable partial denture, so that the bone absorption around the implant is caused.
