Abstract

Aim: This study uses the finite element analysis method to compare the effects of different abutments and prosthetic materials on stress distribution in the rehabilitation of maxillary anterior tooth deficiencies with fixed implanted prostheses.


Methodology: In our study, two titanium implant models with a diameter of 4.1 mm and a length of 10 mm were designed for the maxillary central and canine teeth regions. 3D models of the prosthetic restorations were created with PEEK and fiber-reinforced composite and two different abutment materials (titanium and zirconia). After meshing the materials used with cortical and cancellous bone, Poisson ratio and young module values were loaded into the program. Maxillary central and canine to the palatal surface of the tooth, 2 mm below the incisal edge; a 178 N force was applied in both the vertical and 45° oblique directions, and analysis was performed. The distributions of the highest compression and tensile stress values in peri-implant cortical and cancellous bone were examined, and the results were compared.


Results: Material with low elastic modulus caused higher stress accumulation in the cortical and cancellous bone tissue around the implant during oblique force application.


In all study groups, the maximum stress values ​​observed in the cancellous and cortical bone during oblique force application were significantly higher than those observed during vertical force application. Thus, different prosthetic materials had different effects on stress distribution in peri-implant cortical and cancellous bone tissue, and the highest stress accumulations were in the peri-implant cortical bone.


Conclusion: Different prosthetic materials had different effects on stress distribution in peri-implant cortical and cancellous bone tissue.
