Dental pulp cavity pressure reducing temporary sealing membrane for oral cavity clinics

Abstract

The invention discloses a dental pulp cavity pressure reducing temporary sealing membrane for oral cavity clinics. The dental pulp cavity pressure reducing temporary sealing membrane comprises a support fixed ring, wherein the lower end of a through hole of the support fixed ring is provided with a support frame; the upper surface of the support frame is provided with a filtering membrane; the lower surface of the support fixed ring is provided with a support ring; the support ring is positioned at one side near the through hole of the support fixed ring; the lower end of the support ring is provided with a gauze bag; an inner cavity of the gauze bag is provided with cotton balls; the lower surface of the support ring is provided with a photosensitive resin pasting ring; the photosensitive composite resin pasting ring is positioned at the outer side of the support ring; the support can be performed through the support fixed ring; the filtering membrane can be supported through the support frame, so that the filtering membrane is firmer; higher cleanness and better convenience can be realized during the cotton ball taking through the gauze bag. The dental pulp cavity pressure reducing temporary sealing membrane or oral cavity clinics has the advantages that the structure is simple; the operation is simple and convenient; the installation of the temporary sealing membrane is more convenient; higher cleanness is realized during the taking; the taking uncleanness of the cotton balls can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a temporary sealing film for dental pulp cavity decompression in oral cavity clinics. Background technique [0002] Acute pulpitis is a common disease in oral clinical medicine, and the patient suffers from severe pain when it occurs. The adult dental pulp is limited by its anatomical and physiological conditions, and it is difficult to preserve the living pulp. Clinically, the treatment principle is to remove the pulp tissue, seal the pulp cavity, and preserve the affected tooth. In this method, the pulp tissue with important physiological functions is removed, the resistance of the tooth is reduced, and the life span is reduced. A large number of studies have shown that because the pulp tissue is surrounded by hard dentin walls, once inflammation occurs, the inflammatory exudate in the pulp cavity cannot be drained, the local tissue pressure increases, the blood flow s...

This method removes the pulp tissue with important physiological functions, reduces the resistance of the tooth, and reduces the life span

A large number of studies have shown that because the pulp tissue is surrounded by hard dentin walls, once inflammation occurs, the inflammatory exudate in the pulp cavity cannot be drained, the local tissue pressure increases, the blood flow slows down, and thrombus forms. Unstoppable necrosis after pulp tissue lesions. In the past, some people tried to open the teeth directly for decompression, but a large number of microorganisms in the oral cavity can enter the pulp, leading to iatrogenic infection. Therefore, it is necessary to temporarily seal the pulp cavity. At that time, the existing temporary sealing film was inconvenient to fix, and the pulp cavity needed to be filled with cotton balls, but the existing method was to fill it directly, so it was not clean when it was taken out, so it was very inconvenient to use.
