Abstract

Purpose: Compare two different implant/ abutment internal taper (16� and 11.5�), of three different external design implants to verify the difference on stress values and implant/abutment integrity, after Finite Element Analyses (FEA) and Fatigue test.
Materials & Methods: Fifty-four Morse taper implants were divided into 6 groups (n=9), depending on abutment/implant connection design and implant external design. FEA and Fatigue test (N) were performed. All tested groups were modeled for FEA, simulating a polyacetal base with the installed implant was placed in an angled device of 40�. The Fatigue test was performed at the same conditions described above, and under cyclic loading tests, with a frequency of 15 Hz, according to the specifications of ISO 14801.
Results: FEA demonstrated more homogeneous stress distribution on 16� Morse taper implant. Statistically differences were observed, favoring 16� Morse taper implant, when comparing to 11.5� implant, independently of the external implant design.
Conclusion: According to this study, the implant/abutment internal taper influenced on stress values and implant/abutment integrity, favoring the 16� Morse taper implant.
