The objective of this study was find out the use of dental implants, bone grafts and membrane materials used in implant dentistry between 2005-2015 in Finland. The statutory implant registry was maintained by the National Institute for Health and Welfare. Variables from the implant registry included the patient's gender, age, medical history, indications for implantation, augmentation area, installed fixtures, bone grafts and membranes, complications, removed fixtures and removal indications. Variables were analyzed by using statistical analysis software IBM® SPSS® Statistics (v24). During the time period 166 842 implants were installed and 2351 were removed. The most frequently used bone graft materials were bovine bone graft and autograft, whereas collagen membrane was the most used membrane material. Biomaterials were often used with two-step procedure and mostly in the maxilla. Patients age, gender, biomaterial use, irradiation and smoking were considered risk factors for implant survial. Information data about dental implants and biomaterial use were collected based on voluntary reports from the clinics, therefore the registry is not complete and does not represent the overall statistics.
