Computed tomography (CT) was introduced into dentistry in 1987 to add another dimension to dental implant treatment planning. This technology allowed clinicians for the first time to evaluate anatomic structures with a higher level of accuracy.

In 1999 dental implant planning applications were developed, allowing interactive planning of virtual implants in 2-D and 3-D. The use of radiopaque templates/scanning appliances at the time of the CT scan made it possible for the prosthetic outcome to be incorporated into interactive presurgical planning. This advancement paved the way for an association between radiographic anatomic interpretation, prosthetic treatment planning, and precise surgical execution. Through the use of stereolithography and CAD/CAM technology, surgical templates could be fabricated to help clinicians place implants in a well-planned preoperative/prosthetic manner, rather than intraoperative planning, which is often surgical-driven.

The use of surgical templates can benefit the patient as well as the dental team (restorative dentist, surgical specialist, and laboratory technician). The work performed can be more accurate and less invasive than in traditional cases. The ability to transfer the desired three-dimensional position of implants from the virtual model to the mouth has made this a more efficient outcome.

The surgical template essentially has two functions: one for the surgical phase and one for the laboratory phase. It is used as a laboratory template to fabricate a master model, which is used to create the premanufactured implant-supported prosthesis.

Computer Guided Dental Implant Surgery

The implant was placed using a computer generated surgical guide, fabricated by Anatomage from our pre-surgical treatment planning using In vivo 5 software. Implant was placed virtually in patient's cone beam CT scan. This information was sent to Anatomage, who fabricated surgical guide.
As you can see, everything is treatment planned and placed prior to surgery, eliminating all possible complications that could arise from free-handed implant placement.
This procedure took 45 minutes, start to finish; with no discomfort to patient during and after surgery.
A healing abutment was placed and final restoration will be fabricated in 8 weeks.

Dental Implant Surgery - Computer Guided

This is the first installment in the guided surgery video series featuring Invivo5 and Anatomage Guide. This first video is unique in that it is a live stream from San Francisco to the Anatomage Users Group Meeting held in Napa on April 5th, 2013. Attendees observed the case live followed by question and answer (this video does not include the question and answer session). Dr. Michael Sodeifi performed the surgery at San Francisco Surgical Arts.
