[Clinical evaluation of the Biocomp-implant system. Results after 1,3 and 5 years in a general practice].

: A population of 107 consecutive patients was treated with a new HA-coated, screw-type dental implant (n = 384 implants), the Biocomp implant. Treatment was performed in a general dental practice by one and the same dentist. The implants were utilized for various types of prosthetic constructions, sometimes in challenging conditions with respect to patient selection, jaw bone quantity and quality. A clinical and radiographical evaluation was performed after 1, 3 and 5 years. After 5 years, the chance on implant survival was 87.1% (standard error 3.4%). Implant loss occurred predominantly within the first 1.5 year after implant placement. Particularly short implants, placed in the atrofic maxilla, frequently failed. Biocomp implants that served as abutments for an overdenture in the edentulous mandible or as a single tooth replacement in the upper anterior region had an excellent prognosis.
