Abstract

The invention discloses a prosthesis for repairing the maxillary defects and the preparation method thereof, which includes a silicone rubber outer layer which is in line with the maxillary defect region, a cylindrical skin soft tissue expander inner layer is arranged in the silicone rubber outer layer, the cylindrical skin soft tissue expander inner layer is connected with an inflation device which extends to the outside of the silicone rubber outer layer, and corresponding magnetic retainers are arranged on the silicone rubber outer layer and the cylindrical skin soft tissue expander inner layer or the inflation device. The invention is the prosthesis which has better repair retention, convenient wear and is used for repairing the maxillary defects, and the invention is further establishes the preparation method of the prosthesis.

Description

technical field [0001] The invention relates to a prosthesis for repairing maxillary defects, and also relates to a preparation method of the prosthesis. Background technique [0002] Surgical resection of maxillary tumors and severe maxillary trauma are the main causes of maxillary defects, and tissue defects seriously impair the patient's facial morphology and functions of language, swallowing, and chewing. Due to the lack of elasticity of the lip and buccal tissue after surgery, scar tissue contracture, decreased mobility of the temporomandibular joint, and postoperative radiotherapy, the patient's mouth opening is limited or the cleft of the mouth is narrowed, and the defect is wide and deep. Accurate impression of the defect area can be obtained. It is difficult to take and wear the prosthesis; on the other hand, the retention of the prosthesis is poor, and the use effect is not ideal. In order to avoid the above-mentioned complications, some scholars advocate the use ...
