Method: Nineteen abutments (NobelBiocare, RP Multi-unit), were identified. ISQ bucco-lingual (BL) and mesio-distal (MD) measurements were obtained at abutment level and recorded at one-year post placement. The sample was divided into three groups based on abutment height: Group 1 = 1mm (n=7); Group 2 = 2mm (n=7) Group 3= ≥3 mm (n=5). T-test and ANOVA were performed to compare the data set.
Result: Mean ISQ on all abutments in MD direction was 78.63 ± 8.96 and BL was 51.95 ± 10.75. The mean between MD and BL was significantly different (p≤0.05). Group 1 and Group 3, and Group 2 and Group 3 were significantly different in both MD and BL directions (p≤0.05), while the difference between Group 1 and Group 2 in both directions was not significant (p>0.05). ANOVA was performed to compare the three groups and a significant difference was found in ISQ values in MD among the groups (p≤0.05), but no significant difference in BL (p>0.05).
Conclusion: The ISQ measurements were significantly lower in BL direction compared to MD direction. There is a significant difference in ISQ values at abutment level among different abutment heights especially in those of 3mm or greater.
