Observations on the effects of two ceramics on the strength of bone subjected to cryosurgery

Implants of dense hydroxyapatite and β 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...

Zusammenfassung:	Implants of dense hydroxyapatite and β 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. cryosurgery and these findings are discussed.
