Retrospective study of the survival rates of a surfacetreatedexternal connection implant system

Since the concept of osseointegration wasintroduced by Brånemark in the 1960s, implant shave been widely recommended in the arena ofdental treatment with high success rates being reported (Brånemark et al, 1969; Rosenberg etal, 2004; Hämmerle et al, 2002; Bahat, 2000).

Many authors claim one prerequisite for successful osseointegration is initial stability(Martinez et al, 2001) after implant placement,which depends on the surface characteristics and morphology of the implant and the bonedensityof the surgical site (Meredith, 1998; Barewal,2003). At any given time, a number of surfacetreatment methods are being researched tofacilitate rapid, strong osseointegration.

Many studies have been performed onimplant success rates and a number of different factors are known to be involved in the longterm success of implants. The height of the marginal bone in particular has been found to be a very important factor in determining the functional and aesthetic success of implants, meaning maintaining appropriate height of marginal bone is a prerequisite for a satisfactory long term result
