Abstract
HA, a highly biocompatible, osteoconductive calcium phosphate material provides a permanent support matrix for deposition of fibrous tissue and bone by direct chemical bonding mechanisms. In 1978 our institution initiated prospective clinical trials for ridge reconstruction with dense particulate HA. Atrophic maxillary and mandibular ridges were classified according to the degree of deficiency and were augmented with approximately 4-16 gms of 18-40 mesh irregular shaped particles (1978-81) or 20-40 mesh rounded particles (1981-83). In some of the class III and IV ridge deficiency patients 12-20 grams of HA mixed with finely crushed autogenous cancellous iliac bone (1 gm. to 1 cc) was used to provide increased strength and stability. Surgical technique involved subperiosteal pocket tunneling injection of HA with modified plastic syringes. Maxillary and mandibular splints used infrequently from 1978 to 1981 were more commonly used thereafter.
