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

Embodiment 1

[0022] A visual quantitative model observer, comprising a support 13, an analysis rod 12 and a base; the support 13 is vertically fixed on the base; the analysis rod 12 and the support 13 are arranged in parallel by bolts; the base includes a base shell 7 and The base inner shell 6 is provided with the base inner shell 6 in the base shell 7, the transparent rotating bead 3 is arranged in the base inner shell 6, and the supporting rod 11 is fixedly arranged between the transparent rotating bead 3 and the observation platform 1, and the supporting rod 11 runs through the upper circular opening 5 of the inner shell of the base and the outer shell of the base. The front and side faces of the inner shell 6 of the base are respectively provided with transparent dials 8; the front and side faces of the base shell 7 are respectively provided with horizontal visible windows 9 and the vertical visible window 10; the transparent dial 8 is opposite to the horizontal visible window 9 and th...

Embodiment 2

[0041] The visual quantitative model observer as described in Embodiment 1 differs in that a convex lens is arranged in the base shell 7 and between the transparent dial 8 and the lateral viewing window 9 . The convex lens is used to enlarge the reading of the dial, which is convenient for the operator to read.

[0042] A convex lens is arranged in the base shell 7 and between the transparent dial 8 and the longitudinal viewing window 10 .

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...
