Jawbone Augmentation: Ridge Splitting ProcedureBone graft surgery is commonly used in implant dentistry for the purpose of either fortifying a particular implant site (extractions sometimes cause tiny amounts of bone loss) or for larger scale jawbone rehabilitation when loss is more significant.Difficult extractions, gum disease, resorption, congenital defects (missing incisors) and untreated tooth extractions commonly signal the need for bone augmentation when dental implants are desired for replacing a tooth or creating a fixed bridge. Visit our Bone and Tissue Grafting page for additional details on the different types of graft materials and applicatons of the procedure. No Bone for Implants?
When the width of the jawbone is too narrow, as shown in our first two adjacent photos, manual packing of bone graft material on both sides of the exposed jawbone may heal well and provide a "perceived" healthier width of bone. Being able to withstand the physical forces of biting and chewing, however, may remain in question.
Candidate or Not a Candidate?Patients who have this condition, whether it affects one tooth or several, are often told they are not a candidate for implants.Unfortunately, the number of dentists and specialists who have the access to advanced technologies that are designed to overcome unique bone health problems such as this are relatively few. Using a standard set of dental implant drills cannot be used in this instance. The remaining bone surrounding a standard implant for this patient would be nearly paper thin, practically inviting an implant failure. Creating Candidacy for Dental ImplantsThe task of creating a rock solid environment wherein an implant is fully surrounded by dense natural bone is to physically separate the two walls of the boney ridge and insert the implant with solid packing of hybrid pulverized bone graft material.
The adjacent picture of Dr. Nazarian using a model represents the basic procedure of tapping on the ridge splitter. The walls of the boney ridge are separated to a precise width that accommodates a specific type and size of implant. Osteotome PhysicsThe next picture in this treatment series shows how Dr. Nazarian has completed the successful seating of the osteotome. The large collar is preset to create an implant depth and width that is calibrated with the diagnostic data and the type of implant used.
As with the special drill bits used in common implant dentistry, the osteotome has different "bit sizes" that start from small diameter and progress to the larger, specific diameter that matches the specifications of the implant device. The graduated sizing of bits assures the least invasive movement of bone. The size needed is created slowly in an incremental fashion to promote maintenance of overall hard and soft tissue health.
Depth and width are measured a last time to assure a precision match. Bone Graft ProcedureOnce the implant device is seated, pulverized bone matrix product is manually packed into the surgery site by Dr. Nazarian to create a tight fit for the implant and to add density to the bone, matching dimensions of the ridge along the entire maxilla.
The entire implant and attached healing cap is sutured in, under the repositioned Perio Flap that was created when first exposing the jawbone. Final Crown RestorationApproximately three months later, minor gum surgery is performed to expose the healing cap and resuture the gums to create a snug fit around the implant.
