RESUMEN
PURPOSE: The aim of this study was to evaluate the effect of oral rehabilitation using immediately loaded fixed implant-supported mandibular prostheses, considering chewing, swallowing, speech and voice aspects. MATERIAL AND METHODS: Fourteen patients subjected to this treatment were evaluated by a clinical examination of the stomatognathic system and perceptual evaluation of voice quality before oral rehabilitation, as well as after 1 and 4 months. RESULTS: After oral rehabilitation, the results showed that there were no significant modifications in the aspects investigated. CONCLUSION: Thus, implant-supported prosthetic rehabilitation, despite providing a more satisfactory occlusal standard, did not yield changes in the functional patterns of individuals in this study.
