Appl. No.:

12/151862

Inventors:

Kenneth Guthrie - Ocala FL, US

International Classification:

A61C 13/093

US Classification:

433197

Abstract:

The generation of restorations is easily and effectively achieved by utilizing specific functional considerations that account for typical movement of a patient's mouth. With these movements in mind, the initial starting point for restoration design is the identification of functional occlusal cusps (FOCs) and centric landing pads (CLPs). Based upon the identification and anticipation of these structures, restoration can be designed which will be effectively avoid any interference or undesired interaction between teeth (either existing or restoration). The process of restoration design further considers and designs escape routes for use in configuring the restoration. These escape routes identify those areas anticipated to be occupied by cusps or other components of existing teeth, during natural functional or movement. Consequently, the identification of escape routes helps to place grooves or tracks within the restoration, thus naturally providing clearance. Based upon the consideration of these elements, the resulting restoration is efficient and effective without requiring considerable adjustment by the dentist at the time of fitting.
