Extreme Dental Compensation in an Adult Skeletal Class III Malocclusion: 3-Year Follow-up of a Successfully Compromised Treatment.

Nonsurgical orthodontic treatment of a patient with severe skeletal Class III malocclusion, negative overjet, increased overbite and maxillary crowding is described Although the treatment options included an orthodontic-surgical approach, high cost of the surgical procedure was the main reason for extreme dental compensation to have been performed. Four-premolar extraction protocol associated with intermaxillary Class III elastics were used to correct the malocclusion at the expense of increasing the initial dental compensation without producing any noticeable skeletal change. Satisfactory and stable occlusion was achieved with dental and smile esthetics improvement, but the amount of facial changes was limited by the nonsurgical protocol.

Stability of class II subdivision malocclusion treatment with 3 and 4 premolar extractions.

Background: The purpose of this study was to compare the occlusal stability of class II subdivision malocclusion treatment with 3 and 4 first premolar extractions. A sample of 156 dental casts from 52 patients with class II subdivision malocclusion was divided into two groups according to the extraction protocol. Group 1 comprised 24 patients treated with 3 premolar extractions and group 2 included 28 patients treated with 4 premolar extractions.

Effect of recycling protocol on mechanical strength of used mini-implants.

Purpose. This study evaluated the influence of recycling process on the torsional strength of mini-implants. Materials and Methods.

Selective use of hand and forearm muscles during mini-implant insertion: a natural torquimeter.

Objective: To compare maximum torque produced by different muscular groups and its influence on mini-implant insertion torque and fracture prevention.

Design: A prospective study involving in vivo and in vitro laboratory experiments.

Materials And Methods: Eighty-seven professionals were evaluated for maximum torque produced using a screwdriver with combined action between thumb and index fingers [maximum digital torque (MDT)] and by forearm supination movement [maximum brachial torque (MBT)].

Versatility and benefits of mini-implants for vertical and sagittal anchorage in a growing open bite class II patient.

This case report presents the details of a growing patient with a class II malocclusion, anterior open bite, and posterior crossbite, where the side effects of treatment mechanics were significantly reduced by the use of mini-implants for anchorage.

Predictable drill-free screw positioning with a graduated 3-dimensional radiographic-surgical guide: a preliminary report.

Introduction: Mini-implants are placed in restricted sites, requiring an accurate surgical technique. However, no systematic study has quantified technique accuracy to reliably predict the surgical risks. Therefore, a graduated 3-dimensional radiographic-surgical guide (G-RSG) was proposed, and its inaccuracy and risk index (RI) were estimated.
