골유도재생술을 이용한 수직적 치조제 증강술 : 증례보고

Abstract

In most cases, insufficient alveolar ridge sites often require bone augmentation procedures to restore an adequate bone volume for implant placement. Guided bone regeneration(GBR) is one of the augmentation procedures and well-documented therapeutic method. In the present case, severe vertical bone deficiency was noted on maxillary posterior region. Prior to implant placement, Guided bone regeneration(GBR) procedure with non-absorbable membrane and autogenous/allogenic bone was performed. Trephine biopsy was performed and implants were installed 8 month post-operatively. The biopsy specimens showed newly formed bone with active bone formation. Four month later, healing abutments were connected and the patient was consulted to department of prosthodontics for implant crown restoration. Within the limitation of this case, Guided bone regeneration(GBR) is an effective treatment method for vertical augmentation prior to implant placement in severe vertical bone deficient site.
