Stability of a locking plate and self-drilling screws as orthodontic skeletal anchorage in the maxilla: a retrospective study.

Purpose: The aim of this retrospective study was to determine the success rate of an orthodontic skeletal anchorage system consisting of a locking plate and 2 self-drilling screws to intrude the upper molars and detect factors that contribute to its stability.

Patients And Methods: The subjects were 32 orthodontic and generally healthy patients who had skeletal anchorage plates placed supraperiosteally and unilaterally or bilaterally. The anchorage plate was considered successful if the plate remained stable throughout the period of intrusion of the upper molar without any movement, persistent pain, or infection and was then retrieved without difficulty.

Effects of cortical bone perforation on periosteal distraction: an experimental study in the rabbit mandible.

Purpose: To investigate tissue reactions using periosteal distraction with decorticating holes in a rabbit model.

Materials And Methods: Twenty-five Japanese white rabbits weighing 3.2 to 3.

Horizontal alveolar distraction of the narrow maxillary ridge for implant placement.

Purpose: The purpose of this report was to describe a surgical technique for performing horizontal alveolar distraction of the knife-edge maxillary ridge.

Patient And Methods: The patient was a 17-year-old woman with atrophy of the alveolar rim in the anterior upper jaw, which had inadequate width for implant placement. The transport segment was constructed by the osteotomy of the labial cortex of the alveolus.
