Method for manufacturing sequence occlusion induction occlusal plate by adopting digitization and prepared occlusal plate

Abstract

The invention discloses a method for digitally manufacturing a sequence occlusion induction occlusal plate and the prepared occlusal plate. The method comprises the following steps: firstly, recording upper and lower dentition forms through three-dimensional scanning; a proper occlusal relationship and movement tracks of a mandibular movement hinge shaft, protraction and lateral movement are recorded, relative positions of upper and lower jaw dentitions are positioned by utilizing the occlusal relationship when clinical symptoms are eliminated, and after interference is removed by utilizing the movement tracks, a first occlusal plate is made by applying computer-aided material increase or material decrease. Selecting a stable position after wearing, and recording upper and lower dentition forms again; the occlusal relationship and the mandible motion trail are determined, a germination space is accurately designed at a target tooth position, and a plurality of occlusal plates are established through gradual guiding and occlusal.

Description

technical field [0001] The invention relates to the field of computer posture capture and computer-aided manufacturing technology in the treatment of oral temporomandibular joint diseases and combined orthodontic treatment, in particular to an occlusal plate capable of precise occlusal guidance and a preparation method thereof. Background technique [0002] Temporomandibular joint disease (TMD) is a common oral disease, and its incidence is relatively high in patients with malocclusion. Studies have shown that about 70% of patients with malocclusion have structural abnormalities of temporomandibular joints. Symptoms of TMD include mouth snapping, pain, and even severe limitation of mouth opening. Seriously affect the patient's eating and speaking, thereby endangering the patient's physical and mental health. [0003] The treatment of temporomandibular joint disease is classified according to the etiology, and different treatment options are often used. Including painkiller...

AI Technical Summary

Problems solved by technology

[0006] 1. Unable to establish a correct and stable occlusion at the same time as the occlusal plate is removed: the proper occlusal position obtained after wearing the occlusal plate cannot exist stably after removing the occlusal plate guide

[0007] 2. Cannot effectively provide the starting point and reference position of orthodontic treatment: the orthodontist needs to remove the occlusal plate during orthodontics, and the occlusal position has changed at this time, so the orthodontist cannot get a better orthodontic design origin and destination

The difficulty in solving the above technical problems lies in: how to form a new occlusal stop by contacting some teeth at the position determined by the occlusal plate, so that the occlusion can still be stable at the above position after the occlusal plate is removed
