Use Of Bone Rings For Vertical Augmentation Of The Distal Part Of The Lower Jaw
Initial situation:As a result of an incorrect and outdated approach to prosthetics, bone tissue resorption occurred in the implant area, bone loss in the 4.6 area was 50%, in the 4.7 area – was 30%. Scan shows bone loss. Surgical procedure:Removing the implants and placing the Zenoss ring with new implants inside of it. Following by Zenoss bone graft and membrane placement. After opening the flap and removing the implant 4.7, a bed for the bone ring was formed. With the help of the DSI implant positioner, the place for implant 4.6 was determined. Bone Rings were measured in height and placed in prepared beds, fixed with appropriate implants. The rings were covered with bovine xenograft. The collagen membrane was fixed buccally with a bone pin and covered the site. The flap is sutured with DSI PTFE Sutures. After 4 months...
