Abstract
The primary stability of implants is an important factor to predict the osseointegration.
Recently, the resonance frequency analysis has been used to measure the primary stability. It
is an objective method to monitor the stability of implants during healing phase. This study is
to validate the differences in the effect of the osteotome method according to the bone quality
as well the thickness of cortical bone.
Two hundred seventy implants of 3.75mm in diameter(Neoplant, Neobiotech, Korea) were
placed in 135 bovine ribs. The bone quality is classified into 3 classes according to the number
of bone marrow spaces which implants would be placed, and then classified into 9 subclasses
after the ribs were trimmed. Two implants were placed in 15 specimens of each class.
The conclusion were as follows:
1. In case of less dense cancellous bone, the oseotome method is more effective in primary
stability rather than the drilling method(p〈0.05).
2. If there was cortical bone, it is more advantagous to get stronger primary stability.
3. If cancellous bone is more dense or if cortical bone exists, there is no statistical significance between drilling and osteotome method(p〈0.05).2)
