Diagnostic Models
Study models made from impressions of the arches are invaluable for diagnosis and treatment planning. The model must be mounted on an adjustable or semi adjustable articulator to reproduce correct hinge occlusion and eccentric relation. Models can help detect the following conditions:
Faulty crown contours
Malalignment of teeth in the arches
Abraded occlusal and axial surface
Degree of overbite and overjet
Edentulous area relation of the gingival tissue to the clinical crown
Functional relationship of the teeth
Assessment of resorption and interarch space
Prewaxing of models to produce cosmetic results and functional relationships
Prefabrication of surgical stent
Prefabrication of acrylic temporaries
