title: Comparison of Rehabilitating Missing Mandibular First Molars with Implant- or Tooth-Supported Prostheses Using Masticatory Efficiency and Patient Satisfaction Outcomes.
abstract: OBJECTIVE
  To determine whether a fixed partial denture (FPD) or an implant replacement of a single missing tooth leads to better masticatory efficiency and patient satisfaction.
  
  
  METHODS
  One-hundred and twenty participants with missing mandibular right first molars were selected on the basis of predefined inclusion and exclusion criteria. After obtaining informed consent, 60 participants were randomized to the teeth-supported (FPD) group and 60 to the implant placement group (IMP). The study was divided into the following parts: (i) Completion of a Likert scale satisfaction questionnaire (postrehabilitation) by the participants. (ii) Evaluation of masticatory efficiency and performance 3 months after rehabilitation. Data were evaluated by applying t-test and z-test using statistical analysis (α ˂ 0.05).
  
  
  RESULTS
  Masticatory efficiency of participants in the IMP and FPD groups was 74.95 ± 0.90% and 74.41 ± 3.35%, respectively (p = 0.607). Total satisfaction questionnaire scores for the two groups were also not significantly different; however, the mean scores of overall satisfaction and function categories in this questionnaire were significantly higher for the IMP group, while the mean score for the duration of treatment question was higher for the FPD group (p < 0.05).
  
  
  CONCLUSIONS
  The results of this study suggested that although masticatory performance and efficiency were not statistically different for single teeth replaced with implants or FPDs, patients perceived higher satisfaction with implant restorations; they also preferred the shorter treatment times for rehabilitation in the FPD group.
