Method for planning a dental prosthesis implant arrangement and a reference arrangement

Abstract

The invention includes an apparatus and a method for planning a dental prosthesis implant arrangement. An oral reference arrangement (e.g., a dental tray) can include an alignment portion, configured for extra-oral placement, and having surfaces configured to receive and display an optical reference plane projected from an external reference system. The optical reference plane can provide a reference to align the oral reference arrangement and/or teeth and a jaw of a patient for imaging and subsequent planning of a dental prosthesis implant. A method of planning a dental prosthesis implant arrangement can include initial imaging of the teeth and the jaw of the patient, while the above-described oral reference arrangement is detachably mounted to the teeth and/or jaw of the patient. Three-dimensional information relating to the oral reference arrangement, the teeth, and/or the jaw can be used to generate a virtual model of the teeth and/or the jaw.
