<Abstract><AbstractText Label="PURPOSE" NlmCategory="OBJECTIVE">To compare biomechanical outcomes of immediately and conventionally loaded bar-retained implant-supported maxillary overdentures using finite element stress analysis.</AbstractText>
<AbstractText Label="MATERIALS AND METHODS" NlmCategory="METHODS">Finite element models were created to replicate the spatial positioning of four 4.1 × 12-mm implants in the completely edentulous maxillae of four cadavers to support bar-retained overdentures with 7-mm distal extension cantilevers. To simulate the bone-implant interface of immediately loaded implants, a contact situation was defined at the interface; conventional loading was simulated by "bonding" the implants to the surrounding bone. The prostheses were loaded with 100 N in the projected molar regions bilaterally, and strain magnitudes were measured at the buccal aspect of bone.</AbstractText>
<AbstractText Label="RESULTS" NlmCategory="RESULTS">The amplitude of axial and lateral strains, the overall strain magnitudes, and the strain magnitudes around anterior and posterior implants in the immediate loading group were comparable to those seen in the conventional loading group, suggesting that the loading regimens created similar stress/strain fields (P > .05).</AbstractText>
<AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">Conventional and immediate loading of maxillary implants supporting bar-retained overdentures resulted in similar bone strains.</AbstractText>
