Abstract

We evaluated the microscopical changes that occurred when bone and dental tissue were exposed to such a foreign environment as the ocular surface and anterior chamber in 17 osteo-odonto-keratoprostheses removed from the recipient's eye after 1 to 20 years. Histochemical methods were performed to demonstrate elastic and precursor fibers, while immunohistochemical procedures were used to study the distribution of collagen types I to VI. Islands of heterotopic, newly formed bone were observed in the dentin and the periodontal space, leading to focal dentoalveolar ankylosis. Remodelling and disappearance of the periodontal ligament was never diffuse.
