The biologic principle of guided bone regeneration(GBR) has been studied extensively in hopes of regenerating alveolar bone. Various materials have been utilized as regenerative membranes and grafting materials in implant surgery. To improve the ability of membranes, several types of membrane have been developed. Various materials have been utilized as regenerative membranes; however, all materials have disadvantages, and the ideal membrane material is yet to be identified. In these cases, a homologous gelatinized bone matrix(GBM) were used as a regenerative material in conjunction with the placement of endosseous root implants. 22 patients participated in this study, and 42 implants were inserted. The result of 1st operative surgery was uneventful, inflammatory reaction and dehiscences were not observed except for only one case. After the final protheses, all implants were functioning successfully. The major advantages in the use of GBMs for guided bone regeneration are of very wide application such as membrane and graft material, and that a second procedure to remove the material is not necessary, and the GBMs are accepted by the surrounding tissues without complications. The purpose of this study was to observe the usefulness of GBMs in dental implant surgery.
