Abstract
This study investigated clinical results after autogenous bone grafting to clarify the usefulness of the maneuver. The subjects were 27 males and 32 females, of ages from 14 to 65 years, averaging 31.4 years, at the bone graft. They had undergone repair of cleft palate, augmentation of the alveolar ridge, or elevation of the maxillary sinus floor. The donor sites were the ilium and/or jaws.
The following results were obtained
1. There were no major complications, although some patients had experienced wound dehiscence, infection, or paresthesia around the donor or recipient sites postoperatively.
2. The planned treatment could be performed in 93.2% of the patients.
The investigation of the patients that received implant placement after bone grafting revealed:
1. Greater gain of bone height was possible with the ilium compared with the jaws.
2. The increase of bone height was the maximum in cleft patients and the minimum in augmented patients.
3. The length of the implants installed at the grafted sites was longer than 13 mm in almost all of the patients.
4. A long interval after bone grafting was associated with greater difficulty in implant surgery.
These results reconfirmed the safety and certainty of the technique. An adequate time interval from bone grafting to implant placement is essential for easy placement of the implant.
