Fractured Miniscrew Retrieval through Flapless Vibration Technique: A Mini Review and Case Report

Abstract

Nowadays, miniscrew anchorage system is encouraged to obtain better results in orthodontic treatment. This system also brings emergency complications like fractures during insertion of these miniscrews. According to protocol flap-raising technique, a periodontist should be consulted during retrieval of the fractured miniscrew. Here, we propose a new technique that can retrieve the fractured implant with uneventful healing by the vibration of micromotor blunt burs or ultrasonic scaler tips with reinsertion in 7 days.

A novel approach to retrieve fractured mini implants

“…Various factors are responsible for the fracture of mini screws like the insertion torque, insertion methodology, thread design, bone quality, osseointegration, pilot hole size etc. 2 Majority of mini screw fractures during their insertion are caused by high insertion torque and can be prevented by attending to their insertion torque which ranges from 3 to 10Ncm. 5 Whenever there is a fracture of implant screws the decision to retrieve or not is the main issue as the implant is of a biocompatible material and can be retained in the jaw without any surgical intervention.…”

“…5 Whenever there is a fracture of implant screws the decision to retrieve or not is the main issue as the implant is of a biocompatible material and can be retained in the jaw without any surgical intervention. 2,3 If the decision is made to retain the fractured screw than periodic examinations, both clinical and radiological needs to be done. The decision to retrieve the mini screw depends on the location of the fracture, implant fracture site and the patient's consent.…”

“…1 Later the term Temporary anchorage device (TAD) was introduced by Mah and Bergstrand in 2005 which encompasse those devices that are temporarily fixed to bone to serve as anchorage for the tooth movement and later removed after its use. 2 Mini screw implants are available in various diameter and length. Though the diameter is small and the length is short, mini screws provide stable anchorage for different types of tooth movements.…”
