A 60-year-old male patient had severe bone resorption at site 46 and 47. The plan was to extract #46 and place an implant at site 46. In addition, the GBR procedure using CTi-mem was planned due to bone defects at site 46 and mesial part of 47.

An implant was placed at #46 after 8 weeks of the extraction.

슬라이드4
CTi-mem was placed over the graft and fixed with sutures in the periosteum.

슬라이드5
Autogenous bone chips were harvested in the retromolar site using the ACM drill and a collagen membrane was placed over the CTi-mem.

슬라이드6
Tension-free primary closure of flap was achieved.

The soft tissue has healed without membrane exposures.

슬라이드8
It was verified that the volumetric stability of the bone graft was achieved.
