Intraoral insertion path observation instrument

Abstract

The invention discloses an intraoral insertion path observation instrument. The observation instrument comprises a main body; pressing plates are arranged on the two sides of the main body; a first elastic band and a second elastic band are arranged on the inner side faces of the two pressing plates respectively; a hook-and-loop fastener loop face is arranged on the outer side of the first elastic band; a hook-and-loop fastener hook face is arranged on the inner side of the second elastic band; a silica gel pad is arranged on the rear end face of the main body; a pasting plate is arranged on the rear end face of the silica gel pad; a saliva tissue is arranged on the rear end face of the pasting plate; and a moving cavity is formed in the inner side face of a sliding block. The observation instrument has the advantages that by arranging the first elastic band, the second elastic band, the hook-and-loop fastener loop face and the hook-and-loop fastener hook face, the pasting position can be adjusted according to the head circumference of a patient, so that the observation instrument is better suitable for more people; the silica gel pad is arranged, so that the patient is prevented from being injured by a relatively hard observation device; and by arranging the saliva tissue, saliva flowing out of the patient is sucked away by the saliva tissue, so that the judgment of a doctor is prevented from being affected by the saliva.

Description

technical field [0001] The invention relates to the technical field of in-position tract observation, in particular to an in-position tract observer in the oral cavity. Background technique [0002] The path of insertion is the common direction and angle of the components of the removable partial denture when worn in the mouth. Since partial dentures generally have more than two abutment teeth, the retainers on the denture must be worn in the same direction so that the denture can be in place. The position, shape, inclination, undercut and periodontal health of each abutment are different, and the number and position of missing teeth are also different. Therefore, it is necessary to use the average undercut and adjust the undercut according to certain principles with the help of an observer. The method to determine the position of the denture, the existing scope can not adjust the tightness of the fixation according to the size of the head circumference of different people,...
