Evaluation of transpalatal distraction in cleft palate patients.

Purpose: The aim of this study was to evaluate the effect of combining a bone-borne palatal expander (distractor) with a maxillary osteotomy in the treatment of narrowed maxillae in treated cleft palate patients. Few articles in the literature isolated the effects of transpalatal distraction in cleft patients and most either excluded cleft patients or grouped them with non-cleft patients. The hypothesis is that the use of a bone-borne palatal expander in conjunction with a maxillary osteotomy would improve the amount of maxillary expansion at the anterior segment with less tipping of the segments and provide a harmonious arch form.

Comparison of corticotomy-facilitated vs standard tooth-movement techniques in dogs with miniscrews as anchor units.

Introduction: One method used to accelerate orthodontic tooth movement is the corticotomy-facilitated (CF) technique. The purposes of this study were to (1) identify the effect of the CF technique on orthodontic tooth movement compared with the standard technique, and (2) explore the histologic basis of the difference between the 2 techniques.

Methods: Six dogs, aged 6 to 9 months, were used in this study.

Immediately loaded mini screws: histological study of the effect of two different orthodontic tooth movement techniques.

Unlabelled: The aim of this study was to assess histologically the bone changes around immediately loaded mini screws and whether there is a difference in those changes upon using corticotomy facilitated (CF) orthodontic tooth movement technique, in comparison to standard (S) orthodontic tooth movement technique.

Materials And Methods: Six dogs, aged 6-9 months, were used in this study. Extraction of the maxillary second premolar and mini screw placement were done bilaterally in the maxilla.
