Oral cavity examination ruler for edentulous jaw

Abstract

The invention relates to an oral cavity examination ruler for edentulous jaw, in particular to an inspection ruler for measuring mandibular lingual posterior fossa, sublingual spongy tissue, lingual receding and dental arch width. The inspection ruler is composed of a mandibular lingual fossa measuring end, a sublingual sponge-like tissue measuring end, a caliper and a handle part, the mandibularlingual fossa measuring end is assembled and disassembled at one end of the handle part, and the mandibular lingual fossa measuring ends with different diameters can be assembled and disassembled according to needs. The lower jaw lingual bone posterior fossa measuring end rod part is made of resin, and deforms when the probing strength is larger than 100 g. The sublingual sponge-like tissue measuring head is a small metal ball with the diameter of 7 mm, and a transverse line is arranged in the middle of the sublingual sponge-like tissue measuring head to provide a measuring tool for sublingualsponge-like tissue. A measuring jaw of the caliper can perform 60-degree hinge motion, and a distance between the tail end of the measuring jaw and the sublingual sponge-like tissue measuring head isindicated on a dial by a pointer, namely the width of the dental arch. The scales are marked on the measuring jaw through black and white grids, each grid represents 1cm, and the retreating amount ofthe tongue can be indicated. The ruler integrates multiple measurement functions, and is convenient for clinicians to use.

Description

technical field [0001] The invention relates to an edentulous oral cavity inspection ruler, in particular to an inspection ruler for measuring the mandibular hyoid fossa, sublingual spongy tissue, tongue retreat and dental arch width. Background technique [0002] At present, the restoration methods for edentulous patients include traditional complete dentures, biofunctional dentures, and implant dentures. Among them, biofunctional dentures have less trauma, better effects, and lower costs. Factors such as mandibular hyoid fossa, sublingual spongy tissue, tongue recession, and dental arch width need to be considered in the production of biofunctional dentures. When there is enough space in the posterior fossa of the mandibular bone, the denture base extends to the posterior fossa of the mandibular bone, and the side edge of the tongue contacts with the polished lingual surface of the base to obtain a compensatory closure. In patients with abundant sublingual spongy tissue, ...

AI Technical Summary

Problems solved by technology

At present, the inspection of the posterior fossa of the mandibular bone is mainly based on whether the mouth mirror can be inserted into the posterior fossa of the mandibular hyoid bone with a force of 100g. This force is not easy for doctors to grasp; the inspection of sublingual spongy tissue is mainly based on doctor's observation and subjective judg
