Mini-implants in the anchorage armamentarium: new paradigms in the orthodontics
International journal of biomaterials, 2012
Paradigms have started to shift in the orthodontic world since the introduction of mini-implants in the anchorage armamentarium. Various forms of skeletal anchorage, including miniscrews and miniplates, have been reported in the literature. Recently, great emphasis has been placed on the miniscrew type of temporary anchorage device (TAD). These devices are small, are implanted with a relatively simple surgical procedure, and increase the potential for better orthodontic results. Therefore, miniscrews not only free orthodontists from anchorage-demanding cases, but they also enable clinicians to have good control over tooth movement in 3 dimensions. The miniplate type also produces significant improvements in treatment outcomes and has widened the spectrum of orthodontics. The purpose of this paper is to update clinicians on the current concepts and versatile uses and clinical applications of skeletal anchorage in orthodontics.
Mini Implants in Orthodontics â An Overview
Research & Reviews: Journal of Dental Sciences, 2017
Anchorage control is a key factor in the success of orthodontic treatment. Recent developments in implantology now allows stationary anchorage without the use of extraoral appliances or complex biomechanical procedures. Miniimplants– enhanced anchorage has become a popular concept in orthodontics. Use of skeletal anchorage devices such as osseous dental implants, miniplates, miniscrews or microscrews offers clinicians’ reliable anchorage without patient compliance. Among these anchorage devices, miniscrew implants have increasingly been used for orthodontic anchorage because of their absolute anchorage, easy placement and removal, and cost effectiveness. Therefore, the skeletal anchorage system offers a nonsurgical orthodontic treatment option for skeletal (surgical) malocclusions, as well as a nonextraction treatment for malocclusions characterized by severe maxillary or mandibular protrusion, and/or anterior crowding. The purpose of the present article is to compare the mini- impl...

Interdisciplinary Approach Using Mini-Implants Anchorage - A Case Report
2015
Implants and mini-implants have been used in orthodontics as an important method of anchorage. This method allows the treatment with minimal patients’ cooperation, and also serves as a support for various types of orthodontic movement. The anchorage control is fundamental to the success of orthodontic treatment because of its rigid fixation in the bone. Mini-implants are easily installed, especially using computerized surgical guides. As an additional advantage, they enable the use of various accessories. This paper aims to describe the steps of a detailed preoperative planning for mini-implants through a case study report in order to improve treatment success. Specific software was used for planning and production of a surgical guide with a highly accurate and minimally invasive protocol, through CT and prototypes, increasing accuracy and assertiveness procedures. The success of the treatment was achieved, and the miniimplant remained in function throughout the active orthodontic t...
Use of temporary anchorage devices in orthodontics: A review of the literature
2013
Introduction: In the recent years, it is observed that there is increase in usage of Mini-screws in Orthodontic therapy as a temporary anchorage device, because of their absolute anchorage, easy positioning, easy removal, finally for their low cost. This study consists of a review of the articles published in the literature about these devices. Objectives: They were chosen from "PubMed" several publications from 2006 to 2012 about mini-plates , mini-screws , palatal implants and dental implants as orthodontic anchorage . This review was carried out to evaluate utility and clinical efficacy of the skeletal anchorage devices to determine the most effective system of bone anchorage for orthodontic tooth movement . Discussion: To obtain total control of the anchor during teeth movement, mini-screws represents an efficient in the terms of absolute anchorage compared with the traditional methods used. When a doctor decide to use this devices, it requires the maintenance of healt...
Temporary anchorage devices -Mini-implants
National Journal of Maxillofacial Surgery, 2010
Orthodontists are accustomed to using teeth and auxiliary appliances, both intraoral and extraoral, to control anchorage. These methods are limited in that it is often difficult to achieve results commensurate with our idealistic goals. Recently, a number of case reports have appeared in the orthodontic literature documenting the possibility of overcoming anchorage limitations via the use of temporary anchorage devices-biocompatible devices fixed to bone for the purpose of moving teeth, with the devices being subsequently removed after treatment. Although skeletal anchorage is here to stay in orthodontics, there are still many unanswered questions. This article describes the development of skeletal anchorage and provides an overview of the use of implants for orthodontic anchorage.

Mini-implant Usage in Orthodontic Practice
Turkish Journal of Orthodontics, 2015
Ates x; 3 and Nazan Kü çü kkeles x 4 ABSTRACT Objective: The present study was designed to investigate the general anchorage protocols and especially the tendencies during mini-implant usage among Turkish orthodontists. The main aim of the survey is to reveal if mini-implants are being used more than once and in different patients. Materials and Method: This is a cross-sectional study conducted with orthodontists who are members of the Turkish Orthodontic Society. The orthodontists were asked to click on a link to complete an automated questionnaire of 27 multiple-choice questions. Results: It was found that mini-implants are used by a great majority of the participants and in various cases. General tendencies during mini-implant usage show compatibility with the literature. Conclusion: This survey displays the preferences of Turkish orthodontists regarding mini-implant usage in their clinical practice. Moreover, it is especially important for documenting the fact that mini-implants are being used more than once and also in different patients.
Comparative analysis of anchorage systems for micro implant orthodontics
Progress in Orthodontics, 2010
The study analysed twelve anchorage systems based on micro implants in terms of their bio-mechanical properties and appraised their actual clinical effectiveness. Materials and methods: The analysed micro implants had data provided by the manufacturers or extracted from articles published in specialised journals. The parameters taken into account were: material, surface treatment, head type, length, diameter, neck length, filleted self drilling or self tapping surface, applicable orthodontic forces, possibility of immediate loading, and device removal. Results: Material Grade 5 titanium, titanium alloy (TiAl6V4), surgical steel; surfaces: smooth, sand-blasted and acid etched; head type: bracket, conic with button, round, hexagonal, button with cross cuts, double melted sphere; lengths: between 8.0 to14 mm; diameters: between 1.2 to 2.0 mms; neck lengths: inferior to 1.5 mm and superior to 2.0 mm; filleted portion: self tapping and/or self drilling; applicable orthodontic forces: up to 500 g, possibility of immediate loading, device removal, possibility to use in growing patients. Discussion: The most widely used material was TiAl6V4; most of the surfaces were smooth; the most commonly used head type was the bracket; the most often produced length was the "short" one (8.0-9.9 mm), the most demanded diameter the "smaller" one (1.2-1.4 mms); six systems out of eleven had micro implants with "extra" and "standard" necks; only 3 systems out of eleven produced "non self drilling"devices; all the micro implants analysed were able to withstand orthodontic forces between 150 g and 350 g; all devices were suitable for "immediate loading"; all micro implants had to be removed; all micro implants could be used in growing patients. Conclusions: The comparative analysis showed that micro implants could be used as valid anchorage systems, if dental anchorage was insufficient either in qualitative terms (i.e. parodontal problems) or in quantitative terms (i.e. few dental elements remaining), and in all those situations of limited patient compliance.
