Mini- Implant Materials: An Overview

Purpose: The aim of the present investigation was to review and evaluate the current literature on the mini-implants in orthodontics with regard to their materials properties. The ultimate aim of biomaterials as applied to mini-implants is to serve as efficient temporary anchorage devices. The attainment of this objective is dependent upon a complex interplay of material properties, device design, and physiologic requirements. It is the orthodontist’s responsibility to understand both the materials and structural limitations of these devices and the principles of application to minimize performance failure. Manufacturers use six different titanium-based biomaterials to fabricate mini implants. Each of these materials, including four grade of commercially pure titanium and two titanium alloys and 316L Stainless steel used as a mini implant materials each has distinct mechanical and physical properties. Clinician should recognize these differences for to minimize performance failure and patient care.
