Bone grafting

Dental bone grafting is a regenerative surgery aimed at recreating the bone and so as the supporting soft tissues. Usually conducted for the treatment of periodontitis, this regenerative surgery recreates lost tissues when there is significant loss of gum coverage and supportive bone around the teeth.

Bone augmentation procedures are performed to build the bone for dental implant placement. It might involve placing bone compatible or bone like materials into the jaw. Patients own bone from to her areas also can be used.
Predominant causes of tooth loss:

  • Congenital defect during development
  • Dental cavities and infection
  • Trauma or injury to the area
  • Periodontal disease

How much bone is required?
Generally about 1 mm bone is required and if the implant is next to the tooth or another implant then 2 to 3 mm bone may be required respectively. Bone grafting addresses this insufficiency of bone space.
Dr. Sudhakar Reddy performs different types of dental grafting procedures such as
Alveolar ridge preservation/Socket preservation
A tooth extraction leaves space in the gums surrounded by the alveolar bone whose main function is to provide support to the tooth. There are times when it is not possible to place the implant immediately after extraction. In such a case, the ridge preservation/ socket preservation is performed which fills the void that has been left after removal of the tooth. Usually the ridge preservation graft is a xenograft made of healthy bones from a cow or bovine bone/ autogenous graft from patients own bone or allograft from synthetic bone material . This is applied to the empty space immediately after extraction.
Autogenous grafts
They are noting but bone harvested from patients own bone.they can be of Block grafts, Corticocancellous chips and Cancellous graftsA block of bone is harvested from the patient. These grafts are harvested from different area like lower jaw near the third molars (mandibular ramus) or chin or retromolar areas. Approximately 1 cm or more square of bone graft is obtained and secured with tiny screws. Corticocancellous chips taken with special instruments which can be used in grafting procedures. Cancellous bone is a soft bone obtained either surgically with hand instruments or special instruments.
The subantral graft Known also as the sinus lift procedure, the sinus lift procedure is specifically performed when there is a very small quantity of bone available between the oral cavity and the natural air space present in the maxillary sinus. Placing the implant in the back of the jaw is a lengthy and tedious process and has to be performed by an expert surgeon.
Dr. Sudhakar Reddy is an oral and maxillofacial surgeon who is extensively experienced and well-prepared to diagnose and assess any kind of situations require that dental implants and suggest the most appropriate solutions.
