Abstract

Primary stability is a fundamental criteria of implant success. There has been various trials to
increase initial stability and bone to implant contact. The objective of osteotome technique is to
preserve all the existing bone by minimizing or even eliminating the drilling sequence of the
surgical protocol. The bone layer adjacent to the osteotomy site is progressively compacted with
various bone condensers(osteotomes) this will result in a denser bone to implant contact. This
improved bone density helps to optimize primary implant stability in low density bone. The use
of wide implant is one of methods to increse primary stability. They can be used in special
situations in which they can increase the surface area available for implant anchorage and
improve their primary stability
The aim of this study was to evaluate the influence of the osteotome technique and implant
width on primary stability. Osteotome technique was compared with conventional drilling
method by resonance frequency measurments according to the implant fixtures diameter.
The results were as follows:
1. The average of ISQ value was sightly higher in osteotome technique, but there was not
statistically significant in regular and narrow implant(p〈0.05).
2. Either osteotome technique or conventional technique, ISQ value was significantly higer as
increasing of implant diameter(p〈0.05).
3. ISQ value of drilling technique was higer than those of osteotome technique in wide
implant. It was assumed to be caused by difference in final preparation diameter.2)
