The maxilla (or upper jaw) contains hollow spaces called 'Maxillary Sinus'. The sinuses are located on both sides of the back portion of the maxilla. Bone rapidly becomes resorbed following tooth loss and the sinuses expand through a process called 'Pneumatisation' resulting in further internal bone resorption. There is a limit to the width of cortical bone that can be grafted to a resorbed maxilla. In such cases, it is possible to raise the floor of the sinus and graft a bone substitute into the void created. After this grafted has matured, we can then place dental implants to restore your missing teeth in a normal manner.
Guided Bone Regeneration
Guided bone regeneration (GBR) is dental surgical procedure that use barrier membranes to direct the growth of new bone at sites with insufficient volumes or dimensions of bone for proper Osseo integration ,function, esthetics & longevity of dental implants. It may involve harvesting some innate bone of the patient from another site to be used along with other synthetic bone graft materials and a barrier membrane to cover the graft which in turn stimulates bone regeneration. GBR may be an adunct to your implant placement procedure which would be usually anticipated and informed beforehand by our implant surgeon.
Ridge Split Procedure
Ridge splitting with bone expansion is a technique of manipulation of bone to form receptor site for implant without removing any bone from the implant site. Maxillary bone has inherent quality of flexibility which can molded to desired location by using series of specially designed instruments. This is one of the minimally invasive bone regeneration procedures carried out by our expert implant dentist Dr. Hatkar & can avoid more complex surgeries and/or use of more biomaterials for successful implant osseointegration.
Bone Block Grafting
The block bone graft is necessary when there are large defects in the jawbone. To perform the block bone graft, we harvest a small block of bone from the back of the jaw. We place the block into the defect, then hold it in place with small titanium screws.
