ABSTRACT
The purpose of this case report is to demonstrate the use of orthodontic miniscrew implant in the intrusion of overerupted molar as a preprosthodontic therapy. A 37-year-old woman with an overerupted maxillary right first molar encroaching on the opposing mandibular edentulous space was successfully intruded using a single miniscrew implant and partial fixed orthodontic appliance. The prosthodontic clinician may adopt this conservative and cost-effective strategy in their routine practice and avoid clinical crown reduction.
ABSTRACT
Composite buttons are a valuable adjunct in orthodontic treatment mechanics and provide an esthetic alternative to metal buttons. In particular, their use warrants application in lingual orthodontic therapy or in any minor tooth movement situations. This paper describes the step by step technique for the fabrication of a mushroom shaped composite button for clinical use.

Temporary pontics are a popular strategy to hide tooth extraction sites ('black holes') during course of the orthodontic treatment, especially with lingual appliances. Here, we describe a technique for using the patient's extracted premolar as a temporary pontic.

What are the orthodontic treatment possibilities, limitations and risks inherent in patients with periodontal disorders, particularly active periodontal disease? This case report describes the interface between orthodontics, periodontics and restorative dentistry in the management of a 25-year-old young man with generalized aggressive periodontitis.

The Nickel Titanium (NiTi) closed coil springs serve as an efficient force delivery system in orthodontic space closure mechanics. The closed coil springs with the eyelets come in various lengths to broaden its force characteristics for an expedient space closure. However, at a certain point of time of progressive space closure, the coil spring can be expanded no further for an adequate force delivery. In such situations, the clinician prefers to replace the existing spring with another short length spring. The present article describes a simple conservative technique for progressively re-activating the same NiTi closed coil spring for complete space closure.

INTRODUCTION: There is disagreement concerning the effect of premolar extractions on the dentofacial vertical dimension. It has been suggested that orthodontic forward movement of the posterior teeth after first premolar extraction leads to reduction in vertical dimension. The purpose of this study was to examine cephalometrically the dentofacial vertical changes in Class I Indian subjects treated with and without extractions. METHODS: The extraction group included 31 normodivergent patients (26 female, 5 male; pretreatment age, 17.19 +/- 3.89 years) with maxillary and mandibular first premolar extractions. The nonextraction group included 29 patients (18 female, 11 male; pretreatment age, 18.48 +/- 3.61 years). A coordinate system with the Frankfort horizontal plane and a mandibular fiduciary line was used for the cephalometric calibration. To determine vertical dimension changes due to treatment and to compare differences between the 2 groups, paired and unpaired t tests were performed, respectively. RESULTS: Both groups had increases in linear vertical dimensions (P <0.05), but the change was comparatively greater in the extraction group (P <0.05). Mesial movement of the maxillary and mandibular posterior teeth was coincidental with the extrusion to such an extent that it increased the vertical dimension, although the mandibular plane angle remained unchanged during treatment. CONCLUSIONS: Extraction of teeth only to increase the overbite or decrease the mandibular plane angle might not be justified.
