Abstract: Insufficient bone volume of alveolar ridge remains a major clinical challenge in dental implant surgery. The bone ring technique has emerged as a one-stage and fixation-free approach for ridge augmentation，in which a ring-shaped bone graft is stabilized with a simultaneously inserted dental implant. Bone ring technique doesn′t require additional device to stabilize the grafting bone，and the implantation and stabilization are achieved by preparation of bone ring center. This review summarizes the current progress on the clinical application of bone ring technique and simultaneous implant placement for ridge augmentation.

Key words: bone ring technique, dental implant, ridge augmentation
