Quantified diagnostic work-up casts: applications for interdisciplinary treatment planning.

Diagnostic casts that accurately replicate a patient's occlusion are essential for planning comprehensive care and interdisciplinary treatment. These casts can reveal the actual problem in the spatial relationship between the maxilla and the mandible, which may not be apparent on intraoral examination. Duplicate casts can be altered and measured to quantify the extent of the correction necessary for a predictable result. Treatment planning for interdisciplinary cases requires thorough evaluation of the entire problem and solution set as well as coordination of all procedures. Severe problems and invasive treatments require precise treatment planning. This case report illustrates these principles through multiple applications of quantified diagnostic work-up casts for a patient requiring orthognathic surgery, orthodontics, and occlusal adjustment after a mandibular subcondylar fracture.
