Filter by:The aims of this clinical study are: To evaluate the clinical performance between indirect composite and ceramic laminate veneers: Main interests are: - colour stability of the restoration (digital measurement in follow up) - failure mode of the restoration - wear of the restoration and antagonist Hypothesis: - The colour stability of indirect composite restorations will not be different from the ceramic restorations. - The indirect composite restorations will not be more prone to failure than the ceramic restorations. - Antagonist wear and restorative material wear will be similar for both ceramic and composite. Material and Methods The laminates will be fabricated according to a specified protocol. In order to avoid possible noticeable differences in case of distinct levels of possible discoloration, a modified split mouth design is employed where the central incisors and the symmetric other teeth receive the same type of restoration. Randomization is based on the paired teeth and it is performed using the flip of a coin for the choice of material. Evaluation will be performed at baseline and at follow-up visits annually up to 2 years.
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.
The most frequent reason for failure of laminate veneers made of glass ceramics (feldspathic, leucite based and lithium silicate based ceramics) was fracture of the ceramic, Therefore, ceramic materials that have higher fracture resistance, especially for patients suffering from abnormal occlusion, are needed.
This investigation will be a clinical trial to study the performance of a newly developed high strength ceramic material for crowns. The ceramic has been approved by the FDA for patient treatment. A computer technique will be used to fabricate the crowns in a single appointment without the need for a temporary crown or second appointment. Two adhesive resin cement techniques will be used to hold the crown to the tooth and they will be evaluated for creating sensitivity to the tooth. The purpose of the study is to measure how well the high strength crowns function over an extended period of time.
This study is intended to provide statistically robust evidence that Symbios Demineralized Cortical-cancellous granule mix, Symbios OsteoGraf LD-300, and OsteoGraf/N-300 combined with Symbios OsteoShield Collagen Resorbable Membrane can adequately support the alveolus during ridge augmentation procedures, reducing the dimensional changes of both the alveolus and the overlying soft tissues. Additionally, a comparison between each material will be made, providing further evidence of each materials' ability to preserve the alveolus. It is intended to define in objective terms the response of the hard and soft tissues to ridge augmentation.
Dental restorations (crowns, inlays or onlays) can be made conventionally or by CAD/CAM. The current literature is weak and does not separate the medical results of these two techniques. However, the efficiencies enabled by CAD/CAM could, for the price of an initial investment, improve service to the patient by reducing the time required for these restorations, and possibly lower care costs. The aim of the study is to compare immediate medical results and short-term prosthetic restorations made conventionally or by CAD/CAM in randomized patients, and evaluate economic impacts and organizational aspects.
A randomized parallel-group clinical pilot study was designed to evaluate the impact of glass fiber reinforced composite posts compared to prefabricated titanium posts on long term survival of adhesively restored endodontically treated abutment teeth.
