Abstract: This article illustrates a successful case for reconstructing severely resorbed maxilla. Tent-pole technique in combination with concentrate growth factor were selected as a modification to general guided bone regeneration procedure. Delayed implant placement was performed in order to avoid the fearing of autogenous bone grafting and the risk factors in lateral window for sinus floor elevation. One-year follow-up visit showed that all implants were stable and prosthesis were satisfactory. It is expected that this case will provide new ideas to the bone regeneration protocol for severe alveolar ridge defects.

Key words: tent-pole technique, alveolar ridge augmentation, concentrate growth factor
