초록

In posterior maxilla, it is difficult to achieve primary stability of implants due to sinus pneumatization,
alveolar bone loss, and low bone quality. The accurate and objective primary stability assessment is important
for good prognosis of implants.
Purpose: The aim of this study was to assess the primary stability of the non- submerged, internal type
implants with maxillary sinus augmentation using deproteinized bovine bone mineral by a resonance frequency
analyzer, when residual alveolar bone height is under 8mm
Materials and methods: A total of 20 implants was placed into 5 grafted maxillary sinuses in 5
patients. Deproteinized bovine bone mineral (Bio-Oss) was used as graft material. SSⅡ implants (diameter
4.1mm, and length 11.5mm, SLA suface)) were placed. All of the patients received maxillary sinus
graft procedure by 1-step technique. Residual bone height was 1.3~7.8mm (mean 4.4mm) measured by
panorama radiography. After implant placement, RFA was measured at 4,8,12,20 weeks. The results were
divided into 2 groups; RFA value under 4mm and over 5mm of bone height. It was statistically analyzed.
Results:
1. The primary stability of implants was increased with time
2. The RFA value was above 65 ISQ at 12 weeks
3. There was no correlation between RFA and residual alveolar bone height
in maxillary sinus augmentation by 1-step technique
Conclusion: 1-step surgical procedure is a feasible option for patients with as little as 4mm residual
alveolar bone height , when utilizing non-submerged, internal type implants with xenografts
