Abstract
BACKGROUND: Complex implant treatments have steadily increased within implant prosthodontics. Based on the lower implant mobility, implant impressions need high accuracy in the model transfer to receive a high passive fit within the final prosthodontic restoration. To analyze the accurate 3-dimensional (3D) inter-implant-positions, a reference point is indispensable. However, there is no reference in the patients mouth, so the aim of the present study was to develop a new method based on a custom-made-measuring-aid (CMA) to assess the inter implant dimensions (InID) in patients. MATERIAL AND METHODS: < .05). All data were subjected to univariate ANOVA. RESULTS: evaluation ranged from 42.3μm to 376.7μm(digital) and from 58.3μm to 274.0μm(conventional). There were partially significant differences between the techniques. CONCLUSIONS: Dental Implants, Dimensional Measurement Accuracy, Dental Impression Technique, Intraoral Scanner.
