The present invention relates to a hand held interproximal dental tool for detaching unwanted materials from a patient's teeth and to methods of manufacturing such tools. The interproximal dental tool includes a compact, ergonomically designed housing which is gripped by a dental practitioner during use and a blade extending from and structurally supported by the housing which includes serrations for cutting or abrasive materials for sanding unwanted material.

The present invention actually relates to the field of medical technology, and in particular to a dental preparation surgery simulation method and device. The dental preparation simulation method and device are both applied to electronic equipment, and the electronic equipment is connected to a force feedback instrument. The dental preparation surgery simulation method includes controlling the movement of the surgical instrument model in response to the user's operation on the movement of the force feedback instrument, detecting whether the tooth model collides with the surgical instrument model, and if the tooth model collides with the surgical instrument model collision, in response to the user’s operation, cut the part of the tooth model where the collision occurs, and at the same time, calculate the force generated by the collision according to the preset parameters, and send the calculated force generated by the collision to the force feedback instrument so that the force The feedback instrument restores the force generated by the collision so that the user can perceive it in real time. Through the implementation of this solution, it provides surgery simulation training for dentists, so as to improve the energy saving of actual operation operations, and at the same time save the cost of usual training for dentists.

The present invention proposes an automatic gum line extraction method based on a digital tooth model, including: S1: loading the digital tooth model and performing data preprocessing to obtain the point cloud of the dental model; S2: segmenting the point cloud of the dental model at an equal angle to obtain Multiple dental mold point cloud slices; S3: use gingival line feature screening in each point cloud slice to extract feature point cloud; S4: integrate feature point clouds in all slices, and fit to obtain the extracted gingiva line. The invention does not require user interactive auxiliary input during the detection and extraction process, and the automatic detection of the gum line can be realized after loading the model. The whole processing process makes digital dentistry have better automation and intelligence, and is more accurate and convenient. The patient saves a lot of time and improves the efficiency of diagnosis and treatment.

The invention discloses a dental mirror, which comprises a circular mirror device, a swing arm device and a sliding main rod device; wherein, the circular mirror device is installed on the swing arm device, and the swing arm device is connected with the sliding main Rod device connection; the present invention improves the structure of the oral mirror, adopts a articulated swing arm, cooperates with an adjustment device composed of a slideway, a push block and a connecting rope, and can adjust the lens of the oral mirror at multiple angles, and solves the problem caused by frequent use of the wrist by dentists. Occupational diseases such as tenosynovitis and tendonitis are of great significance to protect the health of doctors' hands.
