Bone Apposition under functional loading

Astra Tech Implantas have been placed at the University of Heidelberg since 1992. The patients have been reexamined clinically and radiologically on a regular basis. In the present clinical study the survival rate of enossal ASTRA TECH Implants as well as the bone situation after functional loading have been examined. The reexamined implants were inserted between 1992 and 2002 at the Clinic and Policlinic of Oral and Maxillofacial Surgery at the University of Heidelberg. Although the thickness of the soft tissue has not been measured in many cases there is no marginal bone loss on the Astra Tech Implants in the sense of an establishment of the 'biological width'.
