2012 Annual Session - Controversies in Surgery: Three Ways to Improve Treatment Planning / Diagnosis and Treatment Planning of Orthognathic Surgery Patients

Controversies in Surgery: Three Ways to Improve Treatment Planning

Treatment of complex orthodontic cases should be based on information from 3D diagnosis, surgical simulation and assessment of treatment outcomes, from clinical trials if possible, but always from a series of consecutively treated patients. Diagnosis of facial asymmetry with quantification of right and left differences, as well as planning of possible surgical procedures in 3D, are particularly challenging. Superimposition of CBCTs on stable structures of reference now allows assessment of 3D dental, skeletal and soft-tissue changes for both growing and non-growing patients. 3D findings reveal more variability in post-surgical stability than previously reported in 2D studies.

Learning Objectives:

The results of studies on controversial aspects in orthognathic surgery:

• Diagnostic quantification of facial asymmetry
• Whether surgical simulation improves treatment outcomes

Diagnosis and Treatment Planning of Orthognathic Surgery Patients

This session will show how to diagnose and plan orthognathic surgery patients using time-tested analyses and methods. The presentation will include analyses used to treatment plan an orthognathic surgery patient, determining if extractions are necessary, and several case reports.
