The guided bone regeneration technique (GBR) is used to facilitate bone regeneration when the thickness of the bone in the jaw is insufficient for the placement of a dental implant.
After placement of the implant, the area of bone deficiency is coated with autogenous bone (the patient's own bone) and/or with an artificial bone replacement material and then covered with a special membrane. In cases when a large amount of bone is required, the GBR is performed before implant placement.
- A dental implant is placed in the area of tooth loss. In cases of excessive bone loss, the implant body is exposed.
- The area of bone loss is filled with crushed autogenous bone or an artificial bone replacement material and covered with an artificial membrane.
- Although each patient has different regeneration times, the alveolar bone is regenerated and the implant can be stabilized in an average period of 4 to 6 months.
It should be noted that it is perfectly feasible to place an implant at the same time bone and lost tissue is regenerated.
