Abstract
Background: The type of implant material for bone ingrowth with appropriate biomechanical properties has long been sought as the ideal bone implant interface. This study aimed to assess the influence of max phase alloy (Ti2AlC) implant on the new bone in growth and biomechanical (push out bond strength test). And this was in comparison with Ti6Al7Nb and cpTi.
Materials and methods: A cylindrical implant was prepared from MaxphaseTi2AlC, Ti6Al7Nb and cpTi with these dimensions (8 × 3) mm height and diameter respectively. In this study, white, male New Zealand rabbits, weighing (2-2.5 kg), aged (10-12 months) were used for implantation of implant cylinder in femur. Then biomechanical (push out bond strength test) and Histomorphometric analysis was performed after 2 and 6weeks of post-surgical implantation. Statistical analysis was performed for data using SPSS version 24.
Results: In this research, Ti2AlC implants achieved the highest push out bond strength. and the recorded mean value for Ti2AlC (10.425+1.155) Mpa as compared with the Ti6Al7NB (7.7630+0.800) Mpa and cpTi implants (3.1440+0.779) Mpa after 2 week implantation in rabbit. Similarly, differences was observed after 6 week implantation. For the histomorphometric analysis, TI2AlC implant recorded a statistically highly significant diferancesis in the mean values of bone and bone implant contact as compared with TI6Al7NB and cpTi.
Conclusion: With in limitation of the present study it can be concluded that, the bone implant interface strength of max phase alloyTi2AlC implant was higher than that of Ti6Al7Nb and cpTi after 2 and 6 weeks implantation in femur of rabbit. And this was coincide with the higher amount of bone and bone implant contact associated with the same material.
