Full Arch ImplantsDr. Tupac has successfully used the All-on-4 technique to provide full arch prostheses for patients without any teeth in either the upper or lower jaw. A recent study again substantiates the success of the technique. An analysis of 800 implants placed following the All-on-4 protocol, from May 2005 until December 2011, at the PI Dental Center, was done. The results of 152 patients showed the CSR (cumulative survival rate) of the implants was 97.3%, 96% in the upper jaw and 97.8% in the lower jaw, 98.1% in males and 96.9% in females and identical success rates (97.3%) for tilted and axial implants. Prosthesis survival was 99%, whether opposing a complete denture or an arch of natural teeth. These are the same success rates of Dr. Tupac's patients.
The advantage of the All-on-4 technique is that tilted implants are used to take advantage of the bone in front of the maxillary sinus and in front of the mandibular foramen, negating the necessity for complicated and expensive bone grafting procedures.
