Notes:
This study was carried out to investigate the effect of acid-alkali treatment and alkaliheattreatment on the push-out strength and tissue response of the porous titanium in vivo. Poroustitanium with different treatment was implanted in dog bony site for 2 months and 5 months and thepush-out strength was tested. At 2 months, the mean push-out strengths of the acid-alkali treatedand alkali-heat treated porous titanium were 11.3 and 15 MPa, respectively. At 5 months, the valuesreached 29.8 and 35 MPa, respectively. Histological observation showed a close contact betweenimplants and bone, and more bone tissue filled inside the pores of porous titanium increasing withimplantation time. The results indicated higher bonding strength between bone and porous titaniumin alkali-heat treated samples. Therefore, alkali-heat treatment can provide porous titanium implantswith better fixation as a bone substitute for clinical use under load-bearing conditions
