【 摘 要 】

Aim The present study was aimed at quantifying implant´s stability and elemental composition by Periotest® and evaluating bone to implant contact (BIC) and crestal bone loss of modified by femtosecond laser zirconia and titanium implants. Materials and methods Forty-eight implants were divided into 2 groups: titanium (control) and modified by femtosecond laser zirconia (test) and then inserted in 6 American Foxhound dogs. Primary stability and secondary stability were measured by Periotest, BIC was evaluated by histomorphometry at 1 and 3 months, elemental composition of the surrounding bone in both groups after 1 and 3 months was assessed. Results Differences between groups regarding primary stability and secondary stability were not significant (p>0.05). The Carbon ratio at zirconia (12.529%) was significantly lower (p0.05) regarding BIC for titanium vs modified zirconia were observed. Crestal bone loss at 3 months was significantly (p<0.05) lower (0.07 ±0.34 mm) in titanium group than in zirconia (1.25 ± 1.73 mm). Conclusion Surface treatment by using femtosecond laser equalizes osseointegration of zirconia implants.
