Relevance of 3D virtual planning in predicting bony interferences between distal and proximal fragments after sagittal split osteotomy.

After sagittal split osteotomy, the mandibular distal and proximal fragments do not always align themselves passively to one another, resulting in bony interferences and subsequent anomalous settlement of the condyles. Predicting these interferences could be an important ancillary procedure for avoiding intra- and postoperative surgical complications, rendering orthognathic surgery more effective and safer. This study evaluated the relevance of virtual surgical planning in assessing the displacement of the proximal segments after virtual distal segment repositioning, for predicting bony interferences between the segments and thus avoiding related intra- and postoperative surgical complications.

Local Ketamine Improves Postoperative Analgesia After Third Molar Surgery.

Purpose: Evidence exists to support the peripheral analgesic effect of local administration of ketamine (LAK) after third molar surgery. The aim of the present systematic review and meta-analysis was to determine the efficacy of LAK in the control of pain, swelling, and trismus after third molar surgery.

Materials And Methods: The study design was a systematic review with a meta-analysis of the effect of LAK after third molar surgery.
