The patients who choose all on four, do so for many reasons including, poor fitting existing dentures, terrible trauma causing tooth loss, decay or periodontal disease causing progressive tooth loss. The most common patients to choose all on four, are not denture wearers. They are patients who have been fighting an uphill battle for a while and know that they are losing their teeth. These individuals have been trying to hold on as long as possible because they do not want to have any time in their life without teeth, and the thought of a removable denture is not an option.
The All on 4 Dental Implants procedure was developed in the mid 1990′s. The all on 4 dental implants system has allowed for a variety of patients who, for various reasons, were not considered good candidates for traditional dental implants to now become candidates.
The All on 4 Dental Implants procedure uses four dental implants per arch (upper or lower). The dental implants in the back are placed on an angle to take maximum advantage of the existing bone structure. Special dental implants were developed that could support the immediate fitting of replacement teeth. This treatment is attractive to those with loose dentures or those in need of full upper and/or lower restorations. With the All-on-4 dental implants procedure, qualified patients receive just four dental implants and a full set of new upper or lower replacement teeth in just one appointment. This usually able to be done without dental bone grafts. The real attraction to the all on 4 dental implants procedure is how quickly permanent dental implants can be placed. This allows patients the ability to leave the same day with a denture that is fixed in place and stabilized by the dental implants.
Traditionally, the approach to restoring a full arch of teeth (either upper or lower) usually involved dental bone grafts, six or more dental implants, and as much as 18 months of treatment. In that time, the patient would be wearing an interim denture while the dental bone grafts and dental implants heal and integrate into the bone. This can be very expensive, time consuming, and uncomfortable for a patient to continuously go back for treatment.
