Abstract

The success of mini implants depends on primary stability followed by secondary stabilization. Resonance frequency analysis has been used to assess the primary stability of implants used in dentistry. There is a paucity in the literature regarding its use in orthodontics. This review attempts to showcase the efficiency and reliability of resonance frequency analysis for assessing stability of orthodontic implants.

Keywords

Abstract

Introduction: This case report describes the treatment of a skeletal Class II malocclusion with an orthognathic maxilla and retrognathic mandible with severely proclined maxillary incisors, imbricated mandibular incisors, deep bite, convex profile and horizontal mandibular growth pattern treated with the Herbst appliance.

Method: Visual treatment objective was initially done to confirm the effectiveness of the use of a functional appliance. Treatment involved the use of a fixedfunctional appliance namely, Herbst appliance to advance the mandible forwards. The case was assessed at T1 and T2 of the initial orthopedic phase of treatment.

Results: At T2, the retrognathism of the mandible was adequately addressed and the facial convexity reduced dramatically. The molars attained a Class I relation and the facial soft tissue profile improved drastically with elimination of lower lip trap.

Conclusion: Functional retrusion of the mandible can be effectively treated in the pubertal period of growth spurt with the judicious use of a fixed functional bite jumping appliance such as the Herbst.

Abstract

A malocclusion created due to a vertical discrepancy is of great interest in the field of orthodontics, because of its etiology, treatment planning and tendency to relapse in the post treatment period. It is important for an orthodontist to recognize its numerous components and understand their interrelationships. This article reviews some of the relevant literature and also some diagnostic and treatment planning suggestions to the orthodontist

Keywords

Abstract

Mandibular symphyseal distraction osteogenesis (MSDO) is nothing but regular distraction osteogenesis (DO)performed at the symphysis wherein, the new bone formation occurs between bone segments that are gradually separated by incremental traction”.Treatment planning decisions in the transverse dimension are based on the mandibular arch width and form. Mandibular symphyseal distraction osteogenesis supplements orthodontic treatment to resolve mandibular anterior width deficiencies or dental crowding.This article focuses on indications, orthodontic preparation, surgical procedures, complications, long term effects and stability of mandibular symphyseal distraction osteogenesis.
