US 2010/0303316 A1 · Mehod of designing and fabricating patient-specific restorations from intra-oral scanning of a digital impression

Abstract

Taking a digital implant or abutment level digital impression by means of intra-oral, computed tomography or other imaging method provides the restorative doctor and laboratory accurate and effective data for determining the implant position, angulation and locking feature orientation without a physical impression. Such data is correlated with a digital library to produce an output which enables design and fabrication of an accurate restorative device such as a prosthetic tooth or crown. In this way the time-consuming, costly and error prone mechanical replication of the relevant dental anatomy is obviated.

Claims6

Dependent claims

A method for designing and fabricating a dental prosthetic restoration based upon the position and orientation of a dental implant previously placed in a patient;

the method comprising the steps of:
a) installing a digital impression coping which properly engages said dental implant;
b) creating an image of the patient's dental anatomy including at least said digital impression coping;
c) transmitting said image to a fabricator of restorative dental prosthetics;
d) using said image to derive a corresponding prosthetic restoration and its relevant position and orientation characteristics for the specific patient and installed implant;
and
e) generating said corresponding prosthetic restoration for installation in said patient.
