A two-year multicentre prospective study was performed from 1992 to 1995 in order to evaluate the real value of various kinds of coral blocks as bone substitute in maxillofacial surgery. This study was supported by the French National Agency for Research Valorization (GBM/TEP procedure). Ten Maxillofacial Surgery Units were included. During this time, 28 coral blocks (23 patients) of two different shapes were used as malar implants for correction of congenital or acquired zygomatic hypoplasia. The mean follow-up was 1.8 year (min: 1.5; max: 2). The tolerance was perfect for 89% of cases. The radiologic opacity never decreased more than 30% and the volume augmentation was always stable at the end of the follow-up period. Three implants were removed because of septic complications. Rigid fixation between the implant and the zygomatic bone appears to be the most important factor of success. On the other hand, the surgical approach (endo- or exo-buccal) does not seem to influence the success rate. The aesthetic improvement was always evaluated as satisfactory and stable by the patients and the surgeons. The authors discuss the real value of the various kinds of biomaterials and especially coral, comparing their personal data with those of the literature. Coral blocks clearly constitute a safe and reliable bone substitute, but further investigations are required to determine its long-term behavior.
