Description

Implant positioning device for dental aligners

technical field

The invention relates to a leveling device for determining the implantation position of a dental implant, in particular to a positioning device for an orthodontic implant installed on a patient with a tooth corrector.

Background technique

Orthodontics is a popular trend in the current society. Generally speaking, the process of orthodontics is first diagnosed to collect the patient's growth records, make plaster models, X-ray examinations inside and outside the mouth, and take pictures of the face and dentition in the mouth, etc. , and then a better treatment plan can be drawn up. Therefore, the quality of the treatment plan is one of the key factors to determine the effect of orthodontic correction, and X-ray examination is an indispensable role in the formulation of the treatment plan, and after the correction, it is necessary to wear the aligner for a period of time It is used to calibrate the teeth to the proper occlusal position, and then carry out mobile orthodontic treatment and retentive orthodontic treatment in sequence according to the treatment plan. At this time, the doctor will also use X-rays to understand the state of the teeth in the orthodontic treatment to determine whether it is necessary to adjust the implant body position and placement of the rest of the implants.

Orthodontic implants can provide a lot of extra strength. When the orthodontist finds any deviation, deep occlusion, insufficient space, etc. during the orthodontic process, the orthodontic implant can be used to make further adjustments to make the teeth move more precisely and more subtle , more efficient, shorten the correction time, and achieve better treatment results. When the implant is to be implanted, the intraoral camera system will be used to take pictures of the oral condition. However, the conventional oral lighting system can only take X-ray images of the teeth for preliminary oral condition judgments, and it does not have any ability to assist the dentist in accurately assessing the condition of the oral cavity. There is a risk of damage to the root of the tooth if you want to implant a corrective implant positioning device. Without any auxiliary tools on the X-ray image, it is really difficult to confirm the effectiveness of the corrective implant. In addition, if the patient's teeth have been fitted with orthodontic appliances, since the orthodontic appliances have been fixed on the top of the teeth, it will inevitably cause a lot of difficulties for the dentist to confirm the state of the orthodontic teeth.
