20100105009 | System, Method And Apparatus For Tooth Implants - A systematic approach to planning and selection of a dental implant. Models of the patient's dentition, including the gingival and supporting bone structure are analyzed in relation to a model of the dentition that will be replaced by the implant. Based on information collected from a missing tooth (or teeth) model, greater insight can be gained into the functional and aesthetic attributes of the implant best suited for the patient. And from this realization a more informed decision can be made for planning the procedure for installation of the implant for the patient, and selection of the implant, e.g., size, type and orientation of supporting fixture and abutment. | 04-29-2010 |
