All-On-4 Dental Implants Create a Lasting Smile

If you are missing multiple or all of your teeth or if they are damaged or diseased, Dr. Robert Harrell and his exceptional team at Harrell Dental Implant Center can give you the brilliant, strong and permanent smile you deserve with an All-on-4 implant. At HDIC, state-of-the-art dental technology combines with an outstanding patient experience to provide you with the highest level of care. As a full-service implant office, we ensure that every aspect of your dental implant procedure can be easily and conveniently handled under our roof.

Often used to replace dentures or missing teeth, the branded procedure All-on-4 uses four titanium dental implants to anchor the upper and lower jaw. This provides a strong foundation for prosthetic teeth, which are added afterwards to complete this permanent procedure. See more at Real Self

All-on-4: Your Best Implant Solution

Imagine a radiant smile free from bone loss or the sunken appearance that commonly accompanies traditional dentures. Dr. Harrell can provide you a comfortable and lasting solution thanks to the All-on-4 dental implant option. Four titanium screws are surgically inserted into your jawbone to support a complete arch of prosthetic teeth. This efficient dental implant solution minimizes the invasive procedure and enables patients to eat and drink normally once the healing process is complete.

The term All-on-4 refers to “all” teeth being supported “on four” dental implants, a prosthodontics procedure for total rehabilitation of the edentulous patient or for patients with badly broken down teeth, decayed teeth or compromised teeth due to gum disease. It consists of the rehabilitation of either edentulous or dentate maxilla and/or mandible with fixed prosthesis by placing four implants in the anterior maxilla, where bone density is higher. The four implants support a fixed prosthesis with 10 to 14 teeth and it is placed immediately, typically within 24 hours of surgery.

Implant manufacturer Nobel Biocare were among the first to identify the evolution of All-on-4 technique as a potential valid and cost-effective alternative to conventional implant techniques, and funded studies by Portuguese dentist Paulo Maló to determine the efficacy of this approach. During this time this technique was also used by various other clinicians around the world.


Description of the procedure

The All-on-4 treatment concept is a prosthodontic procedure (i.e replacement of missing teeth) that provides a permanent, screw-retained, same-day replacement for the entire upper and / or lower set of teeth with a bridge or denture. The procedure is best for patients with significant tooth loss or decay and for people whose bone loss in the jaw area prevents them from getting conventionally oriented (vertical) dental implants. Often, tooth loss is accompanied by loss of the jaw bone which poses the problem of reconstruction of the jaw bone requiring bone grafting. The All-on-4 protocol is considered to be a graftless solution thereby avoiding the long and costly road of rebuilding bone when conventionally oriented implants are used. For the implementation to be successful a careful analysis of the bone structure needs to be made. The most ideal way to evaluate the bone is by a CBCT scan. The All-on-4 protocol is for at least 4 implants to be placed in a jaw. The back implants are typically angled approximately 30 to 45 degrees from the biting plane. The implant is placed in front of the maxillary sinus in the upper jaw (maxilla) and in front of the mental nerve in the lower jaw (mandible). The head of the implant emerges in approximately the second premolar position. This will allow a molar tooth to be cantilevered posterior resulting in a denture or bridge with approximately 12 teeth.

The All-on-4 treatment concept owes its name to the very nature of the method, which consists of applying a dental prosthesis with at least 12 teeth (bridge) fixed in the jaw, based only on four titanium implants. Continue reading at Wikipedia
