Visual quantized model observer

Abstract

The invention relates to a visual quantized model observer, which is characterized in that a connecting rod is arranged between an upper pole and a lower pole of a transparent rotating bead of the observer in a penetrating way; when an observing platform is inclined forwards, backwards, leftwards and rightwards, the connecting rod positioned in the transparent rotating bead indicates the degrees on a transparent dial scale, the degrees are read through a horizontal visual window and a vertical visual window, and the inclined angle of the observing platform can be determined. Guiding lines aredrawn on each dental model by analyzing the lifting and rotation of the rod, so as to distinguish the undercut areas and non-undercut areas of the soft and hard tissues for guiding the design of a snap ring and determining the common insertion path of false teeth. By adopting the visual quantized model observer, the inclined angle of a tooth body can be quantized, so that the design of the false teeth is more standard, the tooth wearing time of a patient is shortened, and good communication is built between doctors and patients finally.

Description

technical field [0001] The invention relates to a visual quantitative model observer, which belongs to the technical field of oral medical instruments. Background technique [0002] In the process of prosthodontic treatment, when designing removable partial dentures for patients, it is necessary to apply the model observer commonly used in the Department of Prosthodontics to determine the common positioning path of the dentures. However, the various observers used clinically can only rely on doctors to describe the inclination direction of the model subjectively, rely on the doctor's experience to determine the inclination direction when the denture is in place, and cannot accurately record the inclination angle of the model, leading to clinical problems. The communication between doctors and technicians is complicated, which not only increases the patient's chair time, but also cannot quickly position the finished dentures when they are put into the patient's mouth, which l...

Problems solved by technology

However, the various observers used clinically can only rely on doctors to describe the inclination direction of the model subjectively, rely on the doctor's experience to determine the inclination direction when the denture is in place, and cannot accurately record the inclination angle of the model, leading to clinical problems. The communication between doctors and technicians is complicated, which not only increases the patient's chair time, but also cannot quickly position the finished dentures when they are put into the patient's mouth, which leads to low work efficiency for clinicians and makes patients deeply feeling dissatisfied
