Abstract

Mini screws represent a new treatment modality in orthodontic biomechanics. They provide absolute anchorage, no secondary movements and reduced orthodontic treatment time. Futhermore, the surgical procedure for mini implants placement is quite simple and this type of treatment requires no patient compliance. We selected a clinical case in order to emphasize one of the most important indications of the mini implants: retrusion of the upper incisors for a incresed overjet case in a young patient. Two mini implants were placed in order to obtain the correction of the overjet and the retrusion of the anterior teeth. The retrusion was obtained in a reduced period of time using retraction devices on crimpable hooks.

Highlights

Mini implants were widely used for different orthodontic situations
Treatment planning must include a good evaluation of the case in order to establish the type of anchorage that needs to be used regarding mini implants: direct or indirect
In order to obtain a good overjet and a better incisor display, mini implants or mini plates can be used for the retrusion of the upper anterior teeth [6]

Summary

Introduction

Mini implants were widely used for different orthodontic situations (uprighting, retrusion of anterior teeth in extraction cases, molar intrusion in anterior open bites, molar protraction, palatal expansion, etc.).The orthodontic (mini)implants simplify the biomechanics in multiple situations and, in terms of anchorage, they eliminate the need for auxiliary appliances [1, 2, 3].
