Abstract

The invention discloses a prosthesis for repairing a maxillary bone defect and a preparation method thereof, a silicone rubber outer layer adapted to the maxillary bone defect area, and a columnar skin soft tissue expansion is arranged inside the silicone rubber outer layer The inner layer of the cylindrical soft tissue expander is connected with an inflation device extending outside the outer layer of silicone rubber, and the outer layer of silicone rubber is connected to the inner layer of the cylindrical soft tissue expander. Or the inflatable device is provided with a corresponding magnetic retainer. The invention is a prosthetic body for repairing maxillary defects with better repair and retention and convenient removal and wear, and establishes a preparation method for the prosthetic body.

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 ...
