Abstract

Mini-screws have brought new perspectives on the prognosis of the orthodontic treatment due to their ability to provide maximum anchorage and minimum compliance from the patient. Biomaterials used for mini-implant manufacturing are stainless steel, chrome-cobalt alloy, commercially pure titanium and grade 5 titanium alloy. These materials influence the type of cellular response in the host tissue, the stability of the device and, finally, the clinical success. Recent research has met the need for clinicians to enhance the stability of these devices through a series of changes to the surface which is in direct contact with bone. This paper aims to analyze the methods used as a surface treatment for orthodontic mini-implants and to evaluate their influence on the stability of these devices. This paper is a synthesis of existing data in the literature, based on inclusion in the analysis of full-text scientific articles relevant for the chosen topic.

Summary

Introduction

Mini-screws have brought new perspectives on the prognosis of the orthodontic treatment due to their ability to provide maximum anchorage and minimum compliance from the patient. Aliajul de crom-cobalt este rar utilizat pentru fabricarea mini-implanturilor din cauza faptului că prezintă o biocompatibilitate mai mică decât aliajul de titan, iar stabilitatea pe termen lung nu este sigură [6,8].
