Dental implants have been long advocated to replace missing teeth but a more recent dental implant technique can help even more people in a cost effective way. For those patients with no teeth or failing teeth, the traditional treatment has been placement of a full removable denture. These removable dentures came with many compromises like poor fit, denture sores, and inability to enjoy the foods we know and love. A newer technique has been developed using only 4 dental implants strategically placed to give support and stability to a traditional removable denture. This procedure is known as all on 4 dental implants.

What Is The All On 4 Dental Implant Procedure?

The All on 4 Dental Implants procedure was developed in the 1990′s by Nobel Biocare. 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 technique uses 4 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. Specially designed dental implants were created 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 the need for 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.

Benefits Of All On 4 Dental Implants

We don’t often give much regard to the importance of the bone our teeth sit in until there is a problem. The bone not only serves as the foundation for our teeth but it also plays a big part in our visual aesthetic appearance. Bone can be lost by tooth removal or periodontal disease. If a tooth is missing or removed, the bone may collapse into the empty socket and cause a sunken appearance to our cheeks or jawbone. A bone graft can restore these problems caused by dental disease or those that result from an accident. One of the main reasons for bone grafts in modern dentistry is to form a good foundation for dental implants.

What is a Bone Graft?

A bone graft is the replacement or augmentation of the bone around the teeth. Bone grafting is a term used to describe a variety of procedures used to add or build bone so that dental implants can be placed.
Dental Bone Grafting
A bone graft typically involves adding bone or bone like materials to the jaw. The bone graft can be your own bone (also called Autologous  bone), synthetic bone, be processed bone obtained from a cadaver (also called Allograft), or can even come from bovine/cow sources (these types are also called Xenografts). After grafting, you generally have to wait several months for the grafted material to fuse or become one with the existing bone structure.  Processed bone grafted materials either cause surrounding bone to grow into the graft or cause cells around the graft to change into bone. Autologous bone transplants bone cells or a block of bone that fuses to the jaw.

Implant Dentistry

It is often used to augment bone to allow for a more successful implant placement. A few reasons for bone grafting in implant dentistry include:
1) Augmenting bone in the sinus area to allow for implant placement.
2) Augmenting bone to enhance the fit and comfort of removable prostheses (dentures)
3) To enhance aesthetics of a missing tooth site in the smile or aesthetic zone. This zone is generally defined as the visible area seen upon full smile, including the teeth, gingiva, and lips.
For a dental implants to be a success, the patient must have sufficient bone in the jaw to place the implant into.
Assumptions were once made that if a patient did not have sufficient quality or quantity of bone in their jaw they would not be suitable candidates for dental implants. Today, thanks to the exponential advances in dental techniques, materials, and technology, patients with insufficient bone in their jaws can have the bone rebuilt using bone grafting.

Bone Grafting Procedure

The actual bone grafting procedure is quite straightforward. A dentist will assess the quantity and quality of your bone during the treatment planning stages. It will be at this time that he/she will determine if there is a need for bone grafting. Then your dentist will review the different types of bone grafts with you and decide which will be the most suitable for your individual case.

Once this has been decided the bone graft procedure can be performed. The actual procedure requires the dentist to place bone under the gum tissue at the site where the bone graft is needed. The dentist will then be able to place the bone to be grafted onto the site and then cover it with a membrane for protection. Membranes are often used to help stabilize the bone graft as well as keep the gum tissue from invading the healing bone graft. The gum tissue will grow at a much faster rate than bone, therefore, membranes are used to prevent gum tissue from growing in and displacing the bone graft before it fully matures.This membrane is also used to protect the boneDental Bone Grafting from any germs found in the oral cavity and ensure that the area is perfectly clean to allow the healing process to take place. Finally, the area is closed and the tissue is stitched into place. Bone graft healing time is usually right around 4-6 months. But this can vary from patient to patient. Patients are given a prescription for antibiotics to take following their bone graft. Antibiotic mouthwashes can also be prescribed to preserve the health of the gum covering the bone graft.

On follow up visits the dentist will check on the success of the bone graft by taking x-rays to determine the height and width of the new bone. Once this has been verified as satisfactory, and the site of the bone graft is completely healed, the next stage of the dental implant process can begin.

Dental bone grafts for the purpose of dental implants has a very high success rate. But there is always a possibility that the bone graft will not work as planned, even if your own bone was used. Bone grafts are not rejected by the body like organ transplants. There is still some mystery as to why some bone grafts fail. We do know that certain people (for example, smokers, diabetics, patients with poor dental hygiene) have higher risks of graft failure.

A failed graft will need to be removed. Once healed properly, you and your dentist may choose to place a second graft.

A bone graft gives the implant dentist and patient one more tool to achieve a successful outcome to just about any implant treatment.
