Familial tooth bone graft for ridge and sinus augmentation: a report of two cases
A 45-year-old male patient was transferred from another dental clinic for maxillary anterior horizontal ridge augmentation. The dentist planned to insert a 6-unit fixed prosthesis after implant placement in the #13 and #23 areas. The condition of the #13 and #23 areas involved an alveolar ridge of insufficient width.() The decision was made to extract the lower right 3rd molar (#48) of the patient and to treat this tissue as autogenous tooth bone graft material. The dentist planned to extract two impacted 3rd molars from the patient's daughter, prepare them as blocks and powder, and use them as graft materials.(, ) On April 10th, 2010, the lower right 3rd molar of the patient was extracted and prepared as powder-type graft material. On the same day, the impacted 3rd molars of the daughter were extracted, prepared as block and powder graft materials, and stored. On April 26th, 2010, in the maxillary anterior edentulous area (#13-#23), a flap was elevated by crestal incision. Block graft materials were grafted to the labial side of the maxillary canine area (#13 and #23 labial area), and additionally, powder graft materials were grafted to the vicinity with tissue adhesive (Greenplast; Green Cross Corp., Yongin, Korea).(-) The area was covered with an absorbable collagen membrane (Ossix Plus; OraPharma Inc., Louis Drive Warminster, PA, USA), and the wound was sutured. Good bone healing without special complications was observed, and the patient was returned to the referred dental clinic for implant placement.() Eight months after the surgery, implantation was performed at a local clinic. The condition of horizontal ridge augmentation was good, and thus 4 implants were placed in the #13, #12, #22, and #23 areas. After 1 week, a temporary prosthesis was installed.(, ) The final prosthesis was carried out in local clinic successfully, further follow up was not performed.
