Active clinical trials for "Diastema"

Descriptive observational cross sectional study Outpatient at faculty of dentistry Cairo university pediatric dentistry department clinic with midline diastema and fully erupted canines will be examined and assess type of frenal attachment to see if correlation present or not

The aim of this study was to evaluate the survival of laminate veneers constructed using a recent polymer-infiltrated ceramic network material following the aesthetic pre-evaluative temporary (APT) technique of tooth preparation in comparison to traditional technique.

The aim of this study was to evaluate the clinical performances of nano-hybrid resin composite systems used for anterior diastema closure and tooth reshaping at 4 years in service using FDI Criteria. Twenty-three patients with diastema problem were enrolled. Nano-hybrid resin composites to be used on each patient were randomly selected. Thirty-seven teeth (10 patients) were restored with Filtek-Z550 (3M/ESPE) in combination with Adper™ Single Bond 2 (3M/ESPE) in Group 1; whereas 39 teeth (13 patients) were restored with Charisma-Diamond (Heraeus Kulzer) in combination with Gluma2 Bond (Heraeus Kulzer) in Group 2, by two operators. Esthetic, functional and biological properties of the restorations were evaluated at baseline, 1-4 years using FDI Criteria establishing a score-range of 1-5. The data were evaluated using the Fisher's Chi-Square (p=0.05).

When restoring teeth with IPS Empress laminate veneers, fracture of restorations may occur. So, material with higher mechanical properties is required. Celtra Duo is a new material with glass ceramics infiltrated by 10% zirconia particles which increase the fracture resistance of the material.
