Photographs of sinus floor elevation in case 1 (a) Gingiva and periosteums were ablated and an oval-shaped groove was formed in the lateral wall of the maxillary sinus. A space was created from the lateral sinus wall region (arrows). (b) There was no perforation of the sinus membrane. OCP/Col discs were implanted into the space. (c) Hard tissue was confirmed at the lateral sinus wall region at 6-months after OCP/Col implantation (arrows). There were no abnormalities or any inflammation at the time of the second dental implant surgery. (d) The final prosthesis was set.

Octacalcium Phosphate (OCP) and collagen composite (OCP/Col) was recognized as a highly osteoconductive bone substitute material based on in vitro and in vivo studies. In this study, OCP/ Col was applied for bone augmentation with sinus floor elevation as a clinical trial. This study evaluated the progress of bone formation via OCP/Col and dental i...

Context 1
... performed sinus floor elevation under local Anesthesia in case 1 and 3, and general anaesthesia in case 2. Gingiva and periosteum were ablated and an oval-shaped groove was formed in the lateral wall of the maxillary sinus. Sinus membrane was ablated from the sinus floor, and the membrane was lifted upward with the oval-shaped bone of the lateral wall region (Figure 3a). There was no perforation of the sinus membrane in any of the cases. ...
Context 2
... was no perforation of the sinus membrane in any of the cases. OCP/Col discs were placed in the space (Figure 3b), and then the gingiva and periosteum were repositioned and sutured. ...
Context 3
... wound healing was satisfactory, and there were no postoperative infections or allergic reactions at the operative site during the observation period. At the time of dental implant placement surgery, hard tissue was confirmed in the lateral window region (Figure 3c). There were no abnormalities or any inflammation at the time of the second dental implant surgery for the exchange of abutments approximately 6 months later. ...
Context 4
... were no abnormalities or any inflammation at the time of the second dental implant surgery for the exchange of abutments approximately 6 months later. After that, a final prosthesis was placed and occlusion was reconstructed (Figure 3d). Each patient had a different type of prosthesis fitted, and the three types were an implant bridge, an implant over denture and an implant crown. ...
