Oxidized cellulose mesh. II. Using hydroxy-apatite bone grafting material in the treatment of infrabony defects.

Biodegradable oxidized cellulose mesh has been used in conjunction with hydroxyapatite synthetic bone grafting material to enhance retention of the graft material and to improve post-operative healing of infrabony defects treated surgically. Initially a good healing response was achieved, but there was a tendency for the sites to relapse in the 8 wk following surgery. A tendency to relapse in reconstructive dentistry is well known, and the possible factors which limit the amount of regeneration of tissues are considered. Although there appear to be limitations on the regeneration possible in tissues, the factors that determine these limitations are poorly understood at present.
