title: Observations on the effects of two ceramics on the strength of bone subjected to cryosurgery.
abstract: Implants of dense hydroxyapatite and beta tricalcium phosphate were implanted over rat mandibular bone, or rat mandibular bone previously subjected to cryosurgery, which is known to produce a reduction in strength. After selected intervals, up to 6 months, the bone was stress-tested to assess fracture strength. Both materials demonstrated an effect in off-setting strength loss after cryosurgery and these findings are discussed.
