Problems solved by technology

[0004] Clinically, pontics can be divided into contact pontics and non-contact pontics according to whether they are in contact with the alveolar ridge mucosa. Contact pontics are widely used, and their advantage is that the pontics will move along with the physiological movement of the abutment teeth on the alveolar ridge. The mucous membrane acts as a massage and slows down the absorption of the alveolar ridge. In addition, it also helps to restore the shape of the neck and pronunciation. In order to make the gingival surface of the bridge body closely contact with the alveolar mucosa tissue, the technician will scrape off part of the defect on the model. The alveolar ridge in the dental area, but now does not scrape different thicknesses according to the patient's gum condition, but generally scrapes 0.5mm, which will cause some patients to have too much scraping on the alveolar ridge Too much pressure, which leads to inflammation of the alveolar ridge mucosa
[0005] At present, in the process of oral clinical operation, some key technologies related to the close contact between the fixed denture pontic and the alveolar ridge mucosa are only estimated by the experience of doctors and technicians, and there is a lack of scientific testing methods, so it is difficult to guarantee the quality of the fixed denture.

Embodiment 1

[0018] 1. Routine clinical preparation of fixed bridges;

[0019] A fixed bridge 2 (refer to figure 1 );

[0020] 2. Set a displacement measuring device (LVDT) 3 on the fixed bridge 2. The center of the displacement sensor 3 contains a vertically movable sliding rod 4, which is perpendicular to the alveolar ridge (equivalent to the simulated alveolar ridge 9); the top of the sliding rod 4 is set There is a push button 5, and the bottom end of the slide bar 4 is provided with a top block 6 which is in contact with the alveolar crest;

[0021] 3. The displacement sensor 3 is electrically connected to the digital display screen 10. By pressing the button 5 on the top of the slide bar 4, the slide bar 4 in the center drives the top block 6 to move downward, so that the top block 6 and the mucous membrane of the alveolar ridge Close contact does not make the mucous membrane pale and anemic, and the small displacement value displayed at this time is the amount that should be scra...

Embodiment 2

[0023] according to figure 1 Shown is the analog detection device of the present invention, comprising a fixed bridge 2, a base column 1, a base 8 and a displacement sensor 3, the base 8 is a simulated alveolar ridge 9, and a base column 1 is respectively provided at both ends of the base 8 , the fixed bridge 2 straddles the two base columns 1; the displacement sensor 3 is installed on the bridge body of the fixed bridge 2; the sliding rod 4 in the center of the displacement sensor 3 is perpendicular to the simulated alveolar crest 9 of the base 8; the sliding rod 4 The top is provided with a push button 5, and the bottom end of the slide bar 4 is a top block 6, and the top block 6 is in contact with the simulated alveolar ridge 9 on the base 8; the displacement sensor 3 is electrically connected with the digital display screen 10, and by pressing the slide bar 4 The top button 5 moves the slide bar 4 downwards so that the top block 5 is in close contact with the simulated al...

Abstract

The invention provides a method of detecting mucosal deformation of alveolar ridge mucosa under action of a pontic. A displacement sensor detects and simulates contact tightness degree of the fixed denture pontic and the alveolar ridge mucosa, displacement is accurately measured, thickness of removal is determined, and medical staff is guided to perform correct medical operations. According to the contact tightness degree of the fixed denture pontic and the alveolar ridge mucosa, the displacement is accurately measured, and the thickness of removal is determined; the thickness of removal in scraping removal is detectable; the method is available for simulating the thickness of required removal and checking the thickness of removal.

Description

technical field [0001] The invention discloses a method for detecting the deformation of the mucous membrane produced by a pontic acting on the alveolar ridge mucous membrane, and belongs to the technical field of dental restorative medicine. Background technique [0002] In dental medicine, for patients with missing teeth, fixed dentures are a common restoration method, and the quality of their production is directly related to the quality of life of these people. [0003] Fixed dentures have the advantages of stability, comfort, durability, high chewing efficiency, and no need for patients to take and wear them by themselves. However, in clinical treatment of patients, there will be many complications caused by improper design and manufacture of fixed dentures, and even lead to repair. Cases of failure, such as chronic inflammation of the mucosal tissue in the area where the bridge body is located after denture repair, manifest as local redness, hyperplasia, ulceration, an...
