OBJECTIVES This study aims at analyzing the changes in gingival crevicular fluid (GCF) lactate dehydrogenase (LDH) activity during orthodontic movement. METHODS Twenty patients all requiring first premolar extractions were selected and treated with conventional straight wire mechanotherapy. Canine retraction was done using 125 g Nitinol closed coil springs. The maxillary canine on one side se...
AIM The aim of this study is to evaluate the efficiency of canine distraction and also to evaluate the position of canine in the arch after distraction. MATERIALS AND METHODS The study sample consisted of five patients, (4 males and 1 female), in the age group of 14 to 25 years who needed canine retraction (ten maxillary canines including both left and right) and first premolar extraction as ...
BACKGROUND The purpose of this systematic review is to identify and review the orthodontic literature with regards to assessing possible differences in canine retraction rate and the amount of antero-posterior anchorage (AP) loss during maxillary canine retraction, using conventional brackets (CBs) and self-ligating brackets (SLBs). METHODS An electronic search without time or language restri...
Normal 0 false false false EN-US X-NONE AR-SA Canine retraction was done for 19 patients. Movement , Tipping and rotation of canine and molar movements was done by two approaches of sliding hook and sliding mechanics using 16% wire and 18% twin edgewise brackets and were compared. 350 g force via elastic chin was applied and measurements were done ...
Background and Aims: Lasers with different characteristics have been used to stimulate orthodontic tooth movements and to inhibit the pain during tooth movements. Considering the contradictory finding in this respect, the effect of low level laser therapy (LLLT) was evaluated on the pain during orthodontic tooth movement. Materials and Methods: In this randomized clinical trial study, 12 patie...
Background and purpose: Low level lasers have been used in dentistry to stimulate orthodontic tooth movement and to inhibit the pain during tooth movements. Contradictory findings exist on this issue, therefore, this study evaluated the effect of laser therapy on pain during orthodontic tooth movement. Material and methods: In this clinical trial, 17 patients with extracted upper first premola...
INTRODUCTION The purpose of this study was to compare and measure the amount of anchorage loss with titanium microimplants and conventional molar anchorage during canine retraction. METHODS Subjects for this study comprised 10 orthodontic patients (7 women, 3 men) with a mean age of 19.6 years (range, 18 to 25 years), who had therapeutic extraction of all first premolars. After leveling and a...
OBJECTIVE To determine optimal loading conditions such as height of retraction force on the power arm and its position on the archwire in sliding mechanics. MATERIALS AND METHODS A 3D finite element method (FEM) was used to simulate en masse anterior teeth retraction in sliding mechanics. The degree of labiolingual tipping of the maxillary central incisor was calculated when the retraction fo...
The purpose of the present study was to verify the effect of exogenous app li cation of Prostaglandi n E, (PGE I) in small dosage on Orthodontic tooth movement in routine orthodontic patients. Fifteen patients were se lected after explaining the experimenta l procedure and obtai ning the wr itten consent. All these patients requi red extract ion of first premolars for the correction of malocclu...
