Abstract

The invention provides a laser-based three-dimensional positioning and guiding device for a root canal therapy dental pulp opening passage. The device comprises a tooth surface positioning assembly and a dental pulp opening guiding assembly, wherein the tooth surface positioning assembly is arranged on a dentition; the dental pulp opening guiding assembly is arranged on the tooth surface positioning assembly; the tooth surface positioning assembly comprises a positioning shell, an inner clamping ring piece and an outer clamping ring piece; a positioning guide hole is formed in the positioningshell; the outer clamping ring piece is arranged at the positioning guide hole of the positioning shell; the inner clamping ring piece is movably connected with the outer clamping ring piece; and thedental pulp opening guiding assembly comprises an X-direction support frame, a Y-direction support frame, an X-direction laser emitter and a Y-direction laser emitter. The device indicates the dentalpulp opening passage through laser, and the effect is intuitive and visual, so that the operation is controllable, and the device is simple and convenient to operate and easy to master. The device canguide more accurate dental pulp opening, the hard tissues of teeth are less removed, and the resistance and functionality of the affected teeth are preserved to the greatest extent, so that the service life of the teeth in the oral cavity is prolonged.

Description

technical field [0001] The invention relates to a laser-based three-dimensional positioning and guiding device for pulp opening access for root canal treatment. Background technique [0002] Periapical pulp disease is a common and frequently occurring oral disease. At present, the most commonly used and effective method in clinical practice is perfect root canal treatment, mainly through thorough root canal preparation, effective root canal disinfection and strict root canal filling to control infection, prevent the occurrence of periapical disease or promote root canal treatment. Healing of periapical disease. [0003] The first step in root canal treatment is to establish a straight line of access to the canal so that instruments can enter the canal and remove the infection. Clinically, this process is mainly completed by doctors based on image-assisted examination. This method of pulp opening relies more on the experience of the doctor, but when encountering variations...
