Comparison of strain energy density (SED) around short implants in the athrophic mandible

Short implants have become an alternative treatment in this posterior region with anatomic limitations. The aim of this study was to compare the biomechanical performance of splinted and non-splinted four short dental implants, in the posterior region of the mandible, by using finite element analysis.

Materials and Methods: By using Rhinoceros software V15, we created four different Three-dimensional models of short implants that had been divided into two different dimensional groups were placed at the site of the mandibular first and second premolar as well as first and second molars. ScanIP was used to simulate the model of an edentulous lower jaw by the CBCT slices. A 75 Pascal compress forces axial load was applied to the occlusal surface of each crown. Stress and strain values were analyzed in specific nodes in cortical and cancellous surrounded bone using Abaqus software.

Results: The maximum stress values under axial load were found in the splinted first molar model. Under an axial load, the first splinted premolar model showed maximum strain values.

Conclusion: Splinting adjacent short implants may provide less bone strain and stress, which can be useful for the parafunctional patients. There is no statistically significant difference between the two different diameter implants in this study.
