Description

Oral implant guide plate fixing device

Technical Field

The utility model belongs to the technical field of oral planting equipment, in particular to baffle fixing device is planted in oral cavity.

Background

In the traditional oral implantation operation, the implantation position of an implanted tooth root is determined by manual visual inspection. The dentist is lack of accurate assistance of high-tech equipment, cannot know the oral condition of the patient in detail, only depends on experience and feeling, and is easy to have deviation or even fail in operation.

Digital planting is the most advanced technology of oral planting at present. It depends on CT scan to measure the height, width and compactness of alveolar bone at the tooth missing part and calculate out relevant data. The doctor determines the optimum position of the implant, including the angle, the depth and the like, by analyzing the three-dimensional data, thereby realizing the stable retention of the implant, and simultaneously, the doctor can be helped to avoid important nerves and blood vessels during the operation, thereby greatly improving the safety of the implant operation.

However, it is a difficult problem in practical operation to precisely return the precisely designed guide plate to the designed position.

Most complex guide procedures can only use the most error-prone mucosa-supported guide because of missing or loose teeth. The positioning of the radiation guide plate and the reduction position of the operation guide plate are affected by the elastic deformation of the mucous membrane, so that operation deviation and even failure are easily caused.
