      Planning: Comparison between Conventional and Digital Diagnostic Wax-Ups.

AB  - OBJECTIVE: The aim of this study was to evaluate the impact of different 
      prosthodontic planning methods on the morphological symmetry of maxillary 
      anterior teeth. MATERIALS AND METHODS: In 13 patients receiving fixed 
      prosthodontic treatment, dental models were obtained from the Oral Health Centre 
      of Western Australia. Two forms of diagnostic prosthodontic planning were 
      executed: conventional wax-up and digital wax-up. The asymmetry was evaluated at 
      two levels: tooth morphological asymmetry (TMA) and anterior segment 
      morphological asymmetry (ASMA). For the TMA, the labial surface of each anterior 
      tooth was superimposed on a mirror image of the contralateral tooth. The ASMA 
      involved superimposition of the combined labial surface of all the anterior teeth 
      on one side on the mirror image of the combined labial surface of the 
      contralateral side. For each asymmetry, the discrepancies in the form of 3D 
      Euclidean distances were calculated and statistically evaluated by the 
      Kruskal-Wallis test (p = 0.05). RESULTS: At the TMA level, the digital wax-up 
      models had significantly less asymmetry (p < 0.00) than the pre-treatment and 
      conventional wax-up models. The pre-treatment and conventional wax-up models had 
      similar asymmetry (p = 0.35). However, at the ASMA level, the difference between 
      the models was insignificant (p > 0.05). CONCLUSION: In this study, the single 
      tooth symmetry had improved after the digital wax-up. However, the conventional 
      wax-up had a minimal impact on single tooth symmetry. ASMA was minimally affected 
      by the two wax-ups.
