Abstract
This case is about a male patient of 55 years old, born in November 1924. At time of his first visit, he still had 20 teeth. Blade Vent Implants were placed to the free end missing in the lower right molar and the intermediate missing of the left molar. After 10 to 14 years due to the worsened prognosis, it became inevitable to remove them. To secure life-prolonging of the two anterior teeth of the mandible, Stabilizer Pin Implant was performed. Thereafter teeth difficult to conserve were extracted to be replaced by partial prosthesis, however due to the periodontal disease which is characteristic of aged patients and the dental neck caries, tooth extraction was inevitable. Since it came to a total loss of teeth both in maxilla and mandible, full denture was placed. While the maxilla was stable, there was a severe bone absorption in the mandible and as it was unstable, four Root Form Implants were placed to secure stability of the denture. Occlusion and aesthetic improved.
