title: Comparison of the acceptability of a new scoring system with Misch's classification for dental implant success determination.
abstract: OBJECTIVE
  The present study aimed at evaluating the acceptability of the Implant Success Index (ISI) in comparison with the conventional classification system.
  
  
  METHODS
  A comparative questionnaire was designed to evaluate 10 criteria that were reported to be important for acceptance of a new classification system. We asked 20 experts who had at least 5 years of clinical experience in implant dentistry to complete a questionnaire based on a visual analog scale. Data were analyzed by a blinded statistician using a Wilcoxon non-parametric rank test.
  
  
  RESULTS
  Measuring all 10 criteria, the acceptability level of ISI was significantly higher than that of the Misch classification (70.90 and 54.90, respectively; P < 0.05). The most significant differences were found in the system's ability to detect early lesions, its lack of overestimation, its quantitative base, and its comprehensiveness. The simplicity and compatibility of the two understudy classification systems were not significantly different.
  
  
  CONCLUSIONS
  ISI seems to be a proper scoring system with a high level of acceptability for determining the success rate of dental implants and for selection of procedures used for improving the status of peri-implant tissue.
