Clinical significanceSuccessful osseointegration requires careful characterization of the thin hydroxyapatite (HA)layer formed on commercially pure titanium during anodization and hydrothermal treatment. This study indicates that the thin HA layer appears to stabilize during the process of bone matrix mineralization in vitro.

Patient:A patient is a 49-year-old female who underwent a total glossectomy, mandibular segmentectomy and immediate reconstructive surgery due to a floor of the mouth carcinoma and a dento-maxillary prosthesis was placed to compensate the jaw defect.Discussion: During three years and five months postoperatively, the dento-maxillary prosthesis condition was good and the patient was very satisfied with the dento-maxillary prosthesis which restored lip-support and improved articulatory and swallowing functions. Frequent recalls were considered necessary to ensure maintenance of good oral care and of the dento-maxillary prosthesis.Conclusion: This is case involved the placement of a dento-maxillary prosthesis following total glossectomy. The prosthesis improved esthetics and function as well as the QOL of the patient.
