Evaluation of hydroxylapatite particles in repair of alveolar clefts in dogs.
Twelve adult mongrel dogs were used to evaluate the use of hydroxylapatite (HA) in the closure of alveolar clefts. Bilateral alveolar clefts were surgically created in each animal. After healing, they were implanted randomly with either HA or particulate cancellous bone and marrow (PCBM). The results were evaluated clinically, radiographically, and histologically for healing, acceptance of the implant, closure of the fistula, and bony ingrowth. The results show that HA was as successful in closure of the fistulas and re-establishing an intact maxilla as PCBM. Minimal osteoid and bone was interspersed in the HA implant sites. No complications resulted from the HA graft.
