Problems solved by technology

To sum up, the problems existing in the existing technology are: the existing devices for oral implant restoration and widening of the attached gingiva cannot accurately simulate the deformation of the gingiva, which affects the restoration effect; at the same time, the restoration of the gingiva is only based on the doctor's clinical experience. There are problems such as large repair error and unsatisfactory repair effect when repairing the gingiva

Abstract

The invention belongs to the technical field of oral medical equipment, and discloses apparatus and method for attached gingiva widening in oral implantation and repair. The apparatus for attached gingiva widening in oral implantation and repair comprises a gingiva image collection module, a main control module, a gingiva image analysis module, a gingiva state evaluation module, a gingiva deformation simulation module, a gingiva repair module, an anti-inflammatory module, and a display module. The simulation efficiency is improved through the gingiva deformation simulation module, so that thedeformed gingiva curved surface is smoother, a fine shape of the gingiva is retained, and thereby the simulation accuracy is improved; and at the same time, a marked gingiva area to be cut is mapped to a gingiva repair guide plate model to obtain an overlapping part through the gingiva repair module, and then a part, overlapping the gingiva area to be cut, of the gingiva repair guide plate model is removed to obtain a repair guide plate model with a repair hole model, so that an error introduced by subjective experiences can be avoided, and the repair accuracy is relatively well ensured.

Description

technical field [0001] The invention belongs to the technical field of oral medical devices, and in particular relates to a device and method for widening the attached gingiva of oral implant restoration. Background technique [0002] Gingiva refers to the reddish structure attached to the neck of the tooth and the adjacent alveolar bone, composed of stratified squamous epithelium and lamina propria. It is a part of the oral mucosa, rich in blood vessels, pale red in color, tough and elastic. Due to the lack of submucosa, it is directly connected with the periosteum, so the gums cannot move. The gums of the elderly often shrink and the necks of the teeth are exposed. The gum is the part of the oral mucosa that surrounds the neck of the tooth and the alveolar process. It is light pink and is the chewing mucosa. There is a clear boundary between it and the red alveolar mucosa, but no obvious boundary with the hard jaw mucosa. The gingiva can be divided into three parts: fre...
