Implant is currently one of the most frequently applied treatments for missing teeth restoration cases throughout the world. However, it is not usual for dentists to find the proper bony support for implants. Guided bone regeneration(GBR) is a method for bone regeneration and it is performed with or without bone graft. The purpose of this study is to consider the efficacy of GBR and that of the treatment of the early membrane exposure. In first case, ridge expansion and autogenous bone graft were simultaneously performed with implant. Non-absorbable membrane was used for this GBR technique. In second case, immediate implantation following extraction of root rests was performed. Non-absorbable membrane was used here as well. The grafting material was allograft. There was a pin-point membrane exposure in both cases two months after the first surgery. Dressing with chlorhexidine and medication has been done for two weeks before membrane removal. Even thought the quantity of regenerated bone was not enough as expected, it was sufficient for implant supports. In conclusion, GBR is an effective treatment option. The proper treatment for complications is expected to lead to successful implantations.
