Description

Tooth planting body base station remove device that breaks

Technical Field

The utility model relates to the field of medical instruments, in particular to a device for taking out a broken abutment of a dental implant.

Background

With the continuous improvement of implant surface treatment technology, the success rate of dental implants has gradually increased. At present, the retention rate in the mouth after 10 years of dental implant restoration can reach more than 95%. However, as the age of the dental implant increases, some mechanical complications also increase. Fracture of the implant abutment is one of the most common mechanical complications.

The oral implant tooth in the prior art comprises an intraosseous implant body, a connecting abutment and an artificial tooth in an oral cavity, wherein the artificial tooth needs to be connected with the implant body through the abutment. Once the implant abutment is broken, the dental crown of the implant can be loosened and even fall off, so that the dental implant cannot perform functions. The broken abutment needs to be taken out and repaired again. If the broken abutment cannot be taken out successfully, the restoration cannot be carried out again, and only the implant can be taken out and is implanted again after the bone is healed.

The base station taking-out method commonly used in clinic is a method of using a high-speed mobile phone to match with diamond turning and needle drilling and grinding or by ultrasonic vibration and the like, but the methods have poor effect and easily damage the inner wall of the implant body, thereby influencing the later repair of the implant body. At present, only individual implant brands are provided with special base station taking-out tools, but the problems of inconvenient operation and the like exist in clinical use.
