Purpose: This study aims to evaluate the aspects of healing around the implants palced with sinus floor elevation without bone grafts
through crestal approach.
Materials and Methods: This study included 7 patients who received implant surgery and 9 implants (3 Osstem Implant IS III SA, 6
CA) with crestal approaching sinus elevation at the Seoul National University Bundang Hospital, South Korea, between May 2014 and
December 2014. We took a CBCT (Kodak 9500 Cone Beam 3D system, Carestream Health, France) and measured the Gray value in
right after surgery, 3 months after surgery, prosthesis loading. We measured the Gray value using the OnDemand’s softwares made by
Cybermed (Korea). We selected the implant which is the same size with the implant placed in implant library made by OnDemand,
overlapped both implants, and measured the Grey value around implant 2 mm.
Results: Among the 9 implants, 1 implant (CA) has failed. The implant’s success rate without bone grafts for 16 months follow-up period
was 89%. Although changing patterns are inconsistent, the same patient’s implants showed a similar Gray value changing pattern. We
confirmed a clear bone gain in 1 patient (CA). Mucosal thickness and haziness seen in the immediate postoperative period were mostly
reduced after 3 months.
Conclusions: Sinus membrane elevation and simultaneous implant placement without bone grafts through crestal approach technique
seem to be good results. (JOURNAL OF DENTAL IMPLANT RESEARCH 2017;36(1):6-13)
