Background and Aim: Implant abutment plays an important role in overall implant success and longevity. Different abutment materials have been experimented to see associated crestal bone losses around implants. Since crestal bone loss is directly related to the implant stability, it is highly significant to explore these clinical factors. Therefore this (one year observational) in vivo study was conducted to assess the effect of three different abutment materials on the crestal bone levels. Materials & Methods: Total three different and popular implant abutment materials were selected for this study. PEEK (Polyether Ether Ketone), surgical grade stainless steel and Titanium have been studied in total 24 patients in which maxillary central incisor was restored by implant. Both male and female patients were included in the study in the age range of 28 to 42 years. Group 1 included 8 patients in which PEEK (Polyether Ether Ketone) based abutment was used. In group 2 total 8 patients were studied in which abutment of Surgical grade stainless steel was used. In group 3 total 8 patients were studied in which Titanium abutment was used. Patients were recalled after 6 months and 12 months periods and means of all four surfaces were taken in to account (for assessing crestal bone levels). P value less than 0.05 was considered significant (p< 0.05). Statistical Analysis and Results: Out of 24 patients, males were 15 and females were 9. For group 1; assessments were made after 6 months and 12 months post operative periods. In 6 months post operative period the mean bone level was 0.29 and in 12 months post operative period the mean bone level was 0.34. The p value was highly significant for 6 months post operative period. For group 2: assessments were made after 6 months and 12 months post operative periods. In 6 months post operative period the mean bone level was 0.32 and in 12 months post operative period the mean bone level was 0.42. The p value was highly significant for 6 months post operative period. Comparison among the 3 study groups was attempted by using one-way ANOVA [for group I, II, III]. Here the estimated p value was highly significant (0.001). Conclusion: Authors concluded that among the all three studied abutment materials, PEEK (Polyether Ether Ketone) and Titanium showed almost similar bone heights in their post operative phases. Moreover, Surgical Grade Stainless Steel showed maximum heights of crestal bone in 6 and 12 months post operative phase therefore stated best among all three. Furthermore, other long term studied are also expected to be performed to validate these outcomes and results.
