Brief Summary:
This study is aiming to evaluate primary stability and bone gain in trans-crestal osseodencification technique using Regular concaved osteotomes at different height elevations.
Detailed Description:
For those patient who need up to 2-6 mm of vertical height, the 1-stage transcrestal osteotome technique shown to be stable over long term.
The most important negative factor that can be inferred from the results is that BAOSFE becomes less predictable when there is 4 mm or less of preexisting alveolar bone height beneath the sinus. Moreover, more challenging situation is the magnitude of tapping force, which may accidently perforate the antral membrane causing a lot of complication in the naso-antral apparatus by excessive taping force. The expansion of the osteotomy sites is performed with a number of Concave tipped tapered osteotomes with increasing diameters that are applied through the edentulous alveolar crest at the inferior border of the maxillary sinus floor. With each insertion of a larger osteotome, bone is compressed, pushed laterally and apically while pushing the garnered bone apically beneath the tented membrane.
