Positioning and measurement device for oral cavity implant correction operation

Abstract

The invention relates to a positioning and measurement device for an oral cavity implant correction operation. The positioning and measurement device comprises a base, modeling plastic, a positioning piece and a clamping and fixing piece. A fixing part is arranged at the top of the base, and the base has the first end and the second end; the modeling plastic is installed on the fixing part, and a stress face is arranged at the top of the modeling plastic and bitten by teeth for positioning; the positioning piece is installed at the top of the base and provided with measurement scales made of X-ray impermeable materials; and the clamping and fixing piece is installed at the first end of the base and provided with clamping space for clamping and fixing X-ray sheets. According to the positioning and measurement device, the measurement scales of the positioning piece are parallel to the X-ray sheets; the stress face arranged at the top of the modeling plastic and bitten by the teeth for positioning is used in a matched mode; the relative relation between the teeth and a measurement standard piece can be displayed through the X-ray sheets obtained through irradiation; and a dentist can rapidly know the tooth root position relation between two teeth.

Description

technical field [0001] The invention relates to a positioning device used in implant surgery, in particular to a positioning device for corrective implants that provides quick interpretation and has accurate measurement references in predicting diagnosis, and is convenient for determining the implantation point of corrective implants. Background technique [0002] With the improvement of the quality of life, people pay more attention to the image of appearance. Having healthy, beautiful and functional teeth, dentition and face can help expand social circles, expand job opportunities and increase self-confidence. Therefore, teeth Orthodontics, orthodontics, and orthodontics are very popular. They can not only promote dental health, but also create a beautiful smile that can be shared with others at any time. [0003] Before corrective surgery in the dentist's office, the patient must undergo a full-mouth examination and evaluation, so that the dentist can understand the relat...

Problems solved by technology

[0004] Although such a detection and evaluation method is simple and trouble-free, it is easy to cause the position of the X-ray film in the patient's mouth to be incorrect due to improper human operation or errors during the X-ray irradiation process, and thus cannot clearly express the gap between the teeth. relative position, therefore, additional time and material costs are often required for re-irradiation

In addition, although the relative position between the teeth can be clearly expressed on the X-ray film, allowing the dentist to know where the implantation position is, it is still impossible to accurately place the implant in the implantation position. May injure the root of the tooth, causing unnecessary damage

[0005] Another detection method is to use computerized tomography to emit an X-ray on the teeth, and then use the computer's three-dimensional technology to reconstruct a three-dimensional image. Therefore, some dentists have gradually begun to use computerized tomography for pre-orthodontic evaluation. , to make it easier for the dentist to judge whether there is an appropriate implant space. Although the use of computerized tomography allows the dentist to accurately place the implant into the preset implant space, the cost of evaluating operations using computer tomography is too high, and Medical expenses that are not affordable by ordinary patients
