Bone and Tissue Regeneration

Bone regeneration/grafting via Socket preservation, Sinus augmentation and Ridge augmentation for Implant site preparation

A dental implant works as an artificial tooth root that is placed in the bone and holds a replacement tooth or bridge. At Andover Periodontics, your periodontist rebuilds the resorbed bone creating a solid implant foundation and places the implant into your jaw to replace a missing tooth. Dental implants are an ideal option for people in good general oral health who have lost a tooth or teeth due to periodontitis, a traumatic injury, or otherwise.

By replacing missing teeth with dental implants, patients effectively save more teeth and tooth structure than by replacing teeth using traditional bridgework, since implants do not rely on the neighboring teeth for support. They function just as your natural teeth do by distributing the biting forces over your jaw bone naturally.

Socket preservation

The best time to start rebuilding the bone for future implant placement is at the time of tooth extraction in order to preserve the existing bone and begin the bone regeneration process. Therefore, at Andover Periodontics your periodontist will often perform a bone regeneration procedure by adding a bone grafting material combined with a biologic material or growth factor, such as Platelet Derived Growth Factor, into the fresh extraction site. The area is then covered by a resorbable membrane over which the gum tissue flap is closed, to begin the process of bone regeneration.

Sinus Augmentation

A key to implant success is the quantity and quality of the bone where the implant is to be placed. The posterior part of the upper jaw has traditionally been one of the most difficult areas to successfully place dental implants due to inadequate bone quantity and quality and the close proximity to the maxillary sinus. A sinus augmentation procedure can help correct this problem by raising the sinus floor and creating bone height to provide a good bony foundation for the placement of dental implants.

Ridge Augmentation

Ridge deformities in the upper or lower jaw due to prior tooth extraction, gum disease or traumatic injuries can leave you with inadequate bone in which to place dental implants. To correct the problem, the gum is lifted away from the ridge to expose the bony defect that is then filled with a bone substitute (graft) to build up the ridge. This ridge augmentation procedure has been shown to significantly improve your chances for successful implants that can last for years to come.

After several months of bone healing, a Cone Beam CT scan of your jaw will be used to provide a detailed radiographic evaluation of the existing bone architecture prior to the implant placement surgery.
