Application of hydroxyapatite implant and bone-hydroxyapatite implant into hydroxyapatite block reconstructed mandibula.

Japanese Journal of Oral & Maxillofacial Surgery, 1991
Applying apatite implants into apatite blocks reconstructed mandibulae was performed in dogs. Apatite implants (A.I.). 5mm in diameter and 9mm in length, and implant for bone-apatite implants (B.A.T.) 4mm in diameter and 9mm in length were used in this experiment.

Thermoluminescence in hydroxyapatite

Medical Physics, 1979
A thermoluminescent (TL) glow peak has been shown to exist at 80°C in synthetic hydroxyapatite, in amorphous calcium phosphate, and in deproteinated rat bone mineral. This TL glow peak is excited by a thermal pretreatment at elevated temperature, followed by exposure to ultraviolet (UV) light. When measured on a cylic TL‐readout UV‐exposure basis after
