There are many issues involved about subperiosteal implant. One of such issues will be the problem of initial fixation. We have developed a method of penetrating screw fixation with metal framework into jaw bone to solve this problem. By penetrating screw, metal framework is fixed to jaw bone with both labial or buccal and palatal or lingual cortical bones. We enrolled 12 patients (12 maxillas and 1 mandible) who were not able to receive endosseous implant due to severe alveolar bone resorption. The median length of follow-up period of the 12 patients was 11 months. If we define a clinically functioning patient who is symptom-free as a successful case, the 11 months success rate is 100%. All patients could ingest normal diet. Subperiosteal implant of penetrating screw fixation with metal framework into jaw bone has advanced its safety by stable fixation.
