Ridge modification is an effective procedure for treating deformities in the upper and lower jaws. These deformities can occur as a result of periodontal disease, trauma, injury, wearing dentures, excessive occlusion, or developmental problems. Some defects can leave insufficient bone for the placement of dental implants and an additional unattractive indentation in the jaw line adjacent to the missing teeth, while others result in excessive bone formation and difficulty in appliance fabrication.
During the ridge modification procedure, the gum is lifted away from the ridge to fully expose the defect in the bone. The bony defect can be filled with bone graft material which can help regenerate lost bone, or excessive bone can be reduced and re-contoured. Finally, the incision is closed and several months of healing will be required. Depending on the case and type of implant and procedure, a dental implant may be placed during the ridge modification procedure or when healing is complete; much depends on the precise condition of the bone. Ridge modification can improve the cosmetic appearance and functionality of the mouth, and can improve the prognosis for many restorations, including dental implants.
