The Inverted Coronoid-Ramus Graft for Condylar Reconstruction.

The purpose of this article is to describe a creative, versatile technique for condylar reconstruction using autogenous mandibular bone. The technique has been used for reconstruction of small condyle and/or ramus defects (approximately 35 to 40 mm in length) typically associated with condylar hyperplasia, condylar tumors, idiopathic condylar resorption, and failed reconstruction attempts. The technique involves excision of the ipsilateral coronoid process-mandibular ramus, inverting it and rotating the segment 180° along its horizontal axis to replace the excised condyle.

Vector control in transportation osteogenesis.

Purpose: To evaluate the ability to control vectors in the technique of transportation osteogenesis using 4 principles.

Patients And Methods: Sixteen defects measuring approximately 30-180 mm were retrospectively evaluated. Vector control was attempted using a single or combination of the following principles: multiple linear vectors, exaggerated linear distraction ("sausage effect"), braced guided distraction, and reorientation osteotomies.
