In this paper the success rate of implant therapy in various bone regions is discussed.
The objective is to determine whether differences existed in success rates of cylinder implants
placed in different areas in the both maxilla and mandible. Forty four patients
have been treated and reviewed five years after the placement of the fixed prosthetic restoration.
The patients were provided with a total of 92 implants. Results from this study
show very low survival rate for implants placed in anterior region of maxilla (55.6%) after
five years. It is concluded that simple cumulative follow up studies do not entirely
correspond to actual situations, positioning the implants has an important role in the
planning of the implant therapy and that important factor for force compensation is not
only the surrounding bone density, but also the region of the jaw where the implants are
