Mechanical behavior of implant-supported full-arch prostheses in different locations in the maxilla: 3D-FEA and strain gauge analysis

The maxillary bone restriction can limit the implants position to support a full-arch prosthesis. Objective: Therefore, this study evaluated biomechanical behavior of prosthesis supported by six in different configurations: group A (implants inserted region canines, first premolars and second molars), B premolar, molar molar) C premolar molar). Material Methods: models were analyzed finite element method validated strain gauge. Three types loads applied: central incisors, molars, obtaining results von-Mises stress peaks microstrain. All registered reported higher concentration all groups, with presenting values structures when compared groups. highest mean microstrain was also observed (288.8 ± 225.2 microstrain), however, there no statistically significant difference between In both regardless magnitude direction load, maximum stresses recorded for displacements lower A. Conclusion: It concluded that an equidistant distribution favors prostheses implants; placement posterior seems be viable alternative rehabilitate totally edentulous individuals.
