Boltons ratio has shown statistically significance differences between plaster and digital casts in mesiodistal measurements of both maxillary and mandibular arches. Results: Correlations showed very high intrarater reliability for measurements made on both plaster and digital casts. Results were statistically analyzed for correlation coefficients and student t –test was performed. Measurements were repeated no less than two weeks later. Overall and anterior Bolton analyses were performed for all models. Measurements of mesiodistal tooth width were made using digital calipers or Nemoceph software.
MAXILLARY ALGINATE IMPRESSION RATIO SOFTWARE
For digital casts, obtained plaster casts were Scanned and imported into software to perform digital cast’s analysis. Thus without damaging dual pour procedure were performed. Casts were removed after cleaning second plaster poured. Impressions were poured in plaster allowed to set for 8-10 minutes. Materials and Methods: Maxillary and mandibular alginate impressions were made for a sample of thirty-six patients with permanent dentitions from first molar to first molar. Sunil Kumar, Shweta RK, Deepti Rajput, Heeralal ChokotiyaĪim : The purpose of this study was to compare the values of Bolton ratio for plaster dental casts versus software -based dental models made from a dual pour alginate impression. Reliability of bolton teeth ratio in dual pour alginate impression with plaster and digital modelsĪuthor Details: Siddharth Sonwane, B.
