En masse retraction and two-step retraction of maxillary anterior teeth in adult Class I women. A comparison of anchorage loss.
OBJECTIVE To compare the amount of anchorage loss of the maxillary posterior teeth and amount of retraction of the maxillary anterior teeth between en masse retraction and two-step retraction of the anterior teeth. MATERIALS AND METHODS The sample consisted of 30 female adult patients with Class I malocclusion and lip protrusion who needed maximum posterior anchorage. The sample was subdivide...
متن کاملEffectiveness of en masse versus two-step retraction: a systematic review and meta-analysis
BACKGROUND This review aims to compare the effectiveness of en masse and two-step retraction methods during orthodontic space closure regarding anchorage preservation and anterior segment retraction and to assess their effect on the duration of treatment and root resorption. METHODS An electronic search for potentially eligible randomized controlled trials and prospective controlled trials wa...
متن کاملMini-implant anchorage for en-masse retraction of maxillary anterior teeth: a clinical cephalometric study.
INTRODUCTION This study was conducted to determine the efficiency of mini-implants as intraoral anchorage units for en-masse retraction of the 6 maxillary anterior teeth when the first premolars are extracted compared with conventional methods of anchorage reinforcement. METHODS Thirty patients requiring high anchorage after extraction of the maxillary first premolars were selected for this s...
متن کاملOptimizing Anterior En Masse Retraction with Miniscrew Anchorage
In severely protrusive patients, skeletal anchorage from miniscrew is often used to avoid anchorage loss with preferred miniscrew location near centre of resistance (Cres) of posterior teeth. Biomechanical requirement for directing retraction force towards Cres of posterior teeth demands the insertion of miniscrew in loose mucosa, where risk of infection and failure increases. In addition, unde...
متن کاملRapid Maxillary Anterior Teeth Retraction En Masse by Bone Compression: A Canine Model
OBJECTIVE The present study sought to establish an animal model to study the feasibility and safety of rapid retraction of maxillary anterior teeth en masse aided by alveolar surgery in order to reduce orthodontic treatment time. METHOD Extraction of the maxillary canine and alveolar surgery were performed on twelve adult beagle dogs. After that, the custom-made tooth-borne distraction device...
