dc.description.abstractObjective: The aim of the study is to compare the effect of monolithic translucent zirconia ceramic (TZI) and monolithic lithium disilicate glass ceramic (LDS) restorative materials on stress distributions in implant components and surrounding bone tissues in implant-supported conometric single crown restorations with a conical connection system by using 3D finite element analysis. Methods: Restorations produced with two different all-ceramic materials using a conometric abutment and a conometric cap on the implant with a conical connection system were placed in the maxillary right second premolar region. 3D finite element analysis was used to examine the amount and distribution of stresses in implant components, in cortical and cancellous bone tissues surrounding the implant and in crowns under vertical and oblique loading. For the statistical analysis one-way ANOVA and independent samples t-test were used (p<.05). Results: In oblique 100N simulation, maximum stress distribution in implant and its components occurred at the implant abutment contact as 475.63 MPa for the LDS. The screw’s peak stress values were determined to be 239.09 MPa in the transition zone and 280.061 MPa in the thread. On the bone surface, maximum and minimum cortical principal stress values were 61.25 MPa and – 62.028 MPa. During oblique loading, LDS exhibited the greatest surface stress on the cap as 441.33 MPa. Generally, tapping phase showed the lowest stress (p<.05). There was no significant difference regarding the materials (p> .05). Conclusion: von Misess and principal stresses are not very high in any location therefore conical connections are more promising in terms of future success.en_US
