Clinical evaluation of Durapatite submerged-root implants for alveolar bone preservation.

A study was undertaken to evaluate the safety and efficacy of Durapatite cones as an immediate submerged-root implant in the mandibular symphysis region. The study involved 30 patients of which 15 received 96 implants and the other 15 served as controls. The clinical and radiographic results revealed the implants to be well-accepted by alveolar bone. No evidence of rejection or major complications were observed. The principal problem which occurred was dehiscence of mucosa over some implants. This problem was attributed to operative technique. There was significantly less vertical bone loss and contour change in the anterior part of mandible in the implant group than in the control group.
