Opening type and opening degree auxiliary detecting and dentition movement track indicating device

Abstract

The invention provides an opening type and opening degree auxiliary detecting and dentition movement track indicating device which comprises a bottom plate, a metal ring, an extension bracket and an indicator member. The outside of the bottom plate is provided with the metal ring, and the inside of the bottom plate is provided with an adhesive surface. The extension bracket includes a bending portion and an extension portion. The bending portion is connected to one end of the extension portion, and the other end of the extension portion is connected with the indicator member. The bending portion hooks the metal ring, and a bonding member is bonded to the bottom plate. The opening type and opening degree auxiliary detecting and dentition movement track indicating device can accurately observe the true movement condition of the dentition of a patient, is convenient to install and operate, can be recycled, and has greater versatility. Moreover, the bottom plate is only installed on the lip surface of the teeth, has no influence on the occlusion relationship and can avoid errors caused by the occlusion, so that the purpose of reducing the errors can be achieved.

Description

technical field [0001] The invention relates to an opening-type auxiliary detection of opening degree and an indication device for dentition movement track. Background technique [0002] In recent years, with the development of image technology and the continuous update of clinical auxiliary diagnostic equipment, the emergence, innovation and promotion of optical technology-based equipment have provided strong conditions for the development of clinical medicine, especially oral and maxillofacial medicine. [0003] However, at this stage, the analysis of the state of the dentition is still mainly based on the physician's clinical examination, the collection of photos of the resting state of the dentition, and the taking of plaster models. However, the movement of the dentition is often a complex dynamic process. It is often difficult to observe the lip and palate (lingual) side of the teeth through the clinical examination of the doctor. Still image analysis also has limitati...

Problems solved by technology

[0003] However, at this stage, the analysis of the state of the dentition is still mainly based on the doctor's clinical examination, the collection of photos of the resting state of the dentition, and the taking of plaster models.

However, the movement of the dentition is often a complex dynamic process. It is often difficult to observe the lip and palate (lingual) side of the teeth through the clinical examination of the doctor. Still image analysis also has limitations such as angle deviation. Taking a plaster model can only reproduce the teeth. Anatomy, adjacency and resting state of maxillary and maxillary occlusion

[0004] In addition, Chinese patent application CN201710139518.7 discloses a method and system for temporomandibular joint motion reconstruction. The teeth are worn with retainers, and the retainers are adapted to the individual dentition, personalized and non-recyclable.

And the polished retainer is used to fix the round wire. The contact area between the two is limited and it is easy to fall off.

In addition, the subject wearing a retainer will affect the occlusal relationship, and the final movement trajectory may produce errors

[0005] To sum up, clinical analysis of the movement state of the dentition is still not intuitive. Doctors often need to rely on clinical experience and repeated multi-angle inspections of the occlusal state to infer the real movement state of the dentition, and the accuracy of the guess is often unavoidable. to guaranteed
