Special oral mirror for restoration of oral cavity

Abstract

A special mouth mirror for oral repair, comprising two lenses, two mirror frames and a mouth mirror handle, the two lenses are respectively installed in the two mirror frames, the end of the mouth mirror handle is connected with the back of one of the mirror frames through a rotating structure, and the mouth mirror The handle can be rotated around the vertical line of the center point of the lens; the angle between the two lenses is adjusted through the hinge structure. 1. By adjusting the angle between the two lenses, the images of the two abutment preparations at different distances can be brought closer to a close enough distance to observe the common seating path of the two abutment preparations; 2. The two lenses are connected by a hinge with the function of adjusting the tightness of the hinge. After the angle between the two lenses is adjusted, it will be fixed and will not be easily changed; 3. Adjust the positional relationship between the handle and the lens, which can adapt to the oral cavity. Observation of teeth at different positions; 4. The special mouth mirror for oral restoration has the advantages of simple structure, convenient use and low production cost.

Description

technical field [0001] The invention relates to a medical device, in particular to a special mouth mirror for oral restoration. Background technique [0002] Crowns and fixed bridges are common restoration methods in oral restorative treatment. The completed crowns and fixed bridges are composed of multiple restorations as a whole. When two or more abutments are in place, they can only Wearing in a specific direction is called a common seating path. If the common seating path is poorly prepared, the stress of the restoration will be concentrated, resulting in damage to the abutment tooth and fracture of the restoration, and in severe cases, the restoration cannot be inserted at all; A large degree of axial-surface polymerization of the abutment will lead to a decrease in the retention force and cause the restoration to fall off. Clinically, it is necessary to prepare a common channel for restorations in place for multiple abutment teeth during tooth preparation, that is, t...
