A Review on Soft Tissue Prediction Techniques in Orthodontics and Orthognathic Surgery―Evolution of Three Dimensional Techniques

The criteria for a successful treatment outcome is not only the correction of skeletal and dental abnormalities but also an aesthetic improvement as judged by both patients and practitioners. The objective of treatment simulation is to allow the clinician to visualize and manipulate the soft tissue structures, so to compare different treatment alternatives.The purpose of this study is to provide a overview on how various three dimensional soft tissue prediction techniques evolved and improved through years.
