Pre-Prosthetic Surgery

Pre-prosthetic surgery

Sometimes surgical modifications of the jaw bone and soft tissues are required to enable the placement of a well-fitting, comfortable and aesthetic dental prosthesis such as dentures or dental implants. This preparation is referred to as pre-prosthetic surgery.

It is important that the bony ridge and soft tissues be of proper size and shape before placing the prosthesis. To achieve this, one or more of the following procedures might be needed

  • Bone smoothing and reshaping (alveoloplasty)- irregular or sharp bone ridges are smoothened off
  • Bone grafting – this is required to “fill in” the bony defects. When there is missing teeth, jaw bone tends to shrink over time. There may not be sufficient bone to place dental implants or prosthesis. Or bone defects may occur due to gum disease. Bone grafting is a procedure to rebuild bone in the bone deficient areas of the jaw. For this, bone may be harvested from other parts of the jaw, patient’s rib or bone substitutes may be used.
  • Removal of excess bone (exostoses)- large and irregular chunks of excess bone may need to be removed to allow denture to fit properly.
  • Adding, removing or reshaping the soft tissues- the soft tissues inside the mouth may require to be surgically corrected to have a well-fitting, stable denture. Excess soft tissue may require to be removed or some tissues may need to be repositioned to ensure a successful prosthesis. Soft tissue grafting may sometimes be required.
