Directly-implanted personalized alveolar bone-repairing prosthesis and preparation method thereof

Abstract

The invention discloses a directly-implanted personalized alveolar bone-repairing prosthesis. The directly-implanted personalized alveolar bone-repairing prosthesis includes a filling body, a left wing part and a right wing part, wherein a retention plate which extends to the left is arranged on the left wing part, a retention plate which extends to the right is arranged on the right wing part, and the filling body is a 3D-printed metal porous body; and an implant mounting end surface is arranged on the upper end of the filling body, and at least one implant abutment is arranged on the mounting end surface. The initial stability of the repairing prosthesis is ensured in a mode which combines the implant abutment with the filling body, and at the same time a mode which combines a dental implant and bones is replaced by a mechanically binding fixing mode of the filling body and the implant abutment, so that the stability of the effect of dental implantation is ensured; and since the filling body has porous structure design, autogenous bone and osteoinductive factors of a patient can be packed inside the prosthesis, and the bones are induced to grow into pores, so that good biocompatibility and binding stability are obtained.

Description

technical field [0001] The invention relates to the technical field of dental implants, in particular to a directly implanted individualized alveolar bone restoration prosthesis and a method for preparing the alveolar bone restoration prosthesis. Background technique [0002] Dental implant surgery is currently the best way to repair missing dentition. Its principle is to drill an implant hole on the alveolar bone in advance, and then screw the implant into the implant hole to osseointegrate with the alveolar bone. If the patient’s alveolar bone is lost due to tumor or mechanical damage, the patient needs to be repaired by bone grafting or bone powder filling, and then a second dental implant operation is performed for the patient who needs dental implantation. For patients with large alveolar bone defects, when the autogenous bone cannot be completely repaired, a prosthetic prosthesis is required for repair. A prosthetic prosthesis generally mimics the shape of the patient...

AI Technical Summary

Problems solved by technology

[0003] Traditional dental implant technology requires bone grafting or bone powder filling in advance, which is complicated and expensive

Especially for a large range of alveolar bone defect cases, a large piece of autogenous bone is required for repair, and the damage is relatively large.

At the same time, patients need a lot of time to recover, and continuing dental implant surgery also requires a lot of time to recover

The whole implant surgery is difficult and requires multiple operations, and the process is cumbersome

At the same time, the initial stability and osseointegration performance of dental implants need to be considered, so the success rate of dental implants in patients with large bone defects is not high
