For appropriate production of the morphology and the occlusal relationship in prostheses, the Guided Bone Regeneration method (GBR method) has long been used in defective areas where the amount of bone is inadequate for insertion of implants into the optimal position. The success rate of this method is high in cases such as wounds after tooth extraction in which four walls are surrounded by bone. However, in cases such as dehiscence and fenestration in which a space for bone regeneration is necessary, bone regeneration as expected does not sometimes occur because of subsidence of the membrane due to pressure by external soft tissue or incomplete fitness and fixation of the membrane.
Therefore, we improved the following procedures and observed good postoperative courses : 1) design of the incision line, 2) space making using an autogenous bone trabecula, 3) the state of fixation of the membrane using a Thread Mate System (TMS), and 4) the suturing method.
