Dermautlocation of the centers of resistance for anterior teeth during retraction using the laser reflection technique.

Center of resistance of anterior teeth. Hyoung jun jang won jong roh bo hoon joo ki ho park su jung kim and young guk park 2010 locating the center of resistance of maxillary anterior teeth retracted by double j retractor with palatal miniscrewsthe angle orthodontist. The aim of this investigation was to define the location of the center of resistance of various consolidated units of the maxillary anterior dentition using a dry human skull when subject to intrusive forces. When horizontal forces were applied the cr for the two and six tooth units was located.

The aim of this study was to investigate the three dimensional 3d position of the center of resistance of 4 mandibular anterior teeth 6 mandibular anterior teeth and the complete mandibular dentition by using 3d finite element analysis. The units studied consisted of two central incisors four incisors and six anterior teeth. The results of study showed that the center of resistance of the 4 maxillary anterior teeth group the 6 maxillary anterior teeth group and the full maxillary dentition group were at 135 mm apical and 120 mm posterior 135 mm apical and 140 mm posterior and 110 mm apical and 265 mm posterior to the incisal edge of the upper central.

Am j orthod dentofacial orthop 91 1987 pp. Lapatkilocating the center of resistance in individual teeth via two and three dimensional radiographic data. Results the center of resistance of the 4 mandibular anterior teeth group was 130 mm apical and 60 mm posterior that of the 6 mandibular anterior teeth group was 135 mm apical and 85 mm.

Finite element analysis of the center of resistance of the mandibular dentition objective. Summary the location of the centre of resistance cr of various consolidated units of maxillary anterior teeth was determined in this study using human autopsy material. The center of resistance of anterior teeth during intrusion using the laser reflection technique and holographic interferometry.

During anterior tooth retraction with sliding mechanics controlled crown lingual tipping bodily translation movement and controlled crown labial movement could be achieved by attaching a power arm length that was lower equivalent or higher than the level of the center of resistance respectively.
