Influence of Abutment Color and Mucosal Thickness on Soft Tissue Color.
Int J Oral Maxillofac Implants
August 2016
Purpose: Zirconia (ZrO₂) and titanium nitride (TiN) implant abutments were introduced mainly for esthetic purposes, as titanium's gray color can be visible through mucosal tissues. This study was aimed at assessing whether ZrO₂ and TiN abutments could achieve better esthetics in comparison with titanium (Ti) abutments, regarding the appearance of soft tissues.
Materials And Methods: Ninety patients were included in the study.
Background: Zirconia abutments were introduced to restore esthetic regions and showed sufficient stability to support implant restorations. Nonetheless, to date the observation periods are shorter than those of titanium abutments.
Purpose: To assess the survival of implant crowns supported by computer aided design-computer aided manufacturing (CAD-CAM) abutments after 3 years.
Purpose: This randomized clinical trial assessed the effect of three different prosthetic abutments (titanium, gold-hue titanium and zirconia) on peri-implant soft tissue 2 years after treatment in partially edentulous subjects.
Methods: Baseline data concerning (1) thickness of the buccal peri-implant soft tissue, (2) soft tissue thickness above the bone crest, (3) depth/length of transmucosal pathway, and (4) periodontal biotype at adjacent teeth were collected. The final sample consisted of 47 subjects (21 males, 26 females) with a total of 97 implants.
The study aimed at assessing and estimating the fatigue resistance of different fiber posts and to observe their ultrastructures through SEM. Six types of fiber posts were used: GC Fiber Post (Group 1), ParaPost Fiber White (Group 2), FibreKor (Group 3), DT Light-Post radiopaque (Group 4), FRC Postec (Group 5), and Luscent Anchors (Group 6). Ten out of 15 posts within each group were used for the fatigue test, and the other five were processed for SEM evaluation.
View Article and Find Full Text PDFPurpose: This literature review aimed to find answers to relevant questions regarding the clinical outcome of endontically treated teeth restored with fiber posts.
Materials And Methods: All clinical studies published since 1990 in journals indexed in MEDLINE were retrieved by searching PubMed with the query terms "fiber posts and clinical studies." The reference list of the collected articles was also screened for further relevant citations.
Purpose: To assess whether the amount of residual coronal dentin and the placement of a prefabricated (DT Light Post) (LP) or a customized fiber post (Ever Stick Post) (ES) have a significant influence on the 3-year survival of endodontically treated premolars.
Methods: A sample of 345 patients provided six groups of 60 premolars in need of endodontic treatment. Groups were defined based on the amount of dentin left at the coronal level after endodontic treatment and before abutment build-up.
Purpose: The aim of this in vivo study was to clarify how blistering formation occurs along intraradicular dentin bonded interfaces.
Materials And Methods: Patients were selected and post space was prepared in vivo in endodontically treated teeth. Post space was etched, dried with ethanol, and bonded with one of the following adhesive systems: All Bond 2, XP-Bond, Clearfil SE Bond, Xeno III.
Purpose: The aim of this clinical study was to evaluate the postoperative hypersensitivity of Empress II inlays/onlays luted under clinical conditions with XP BOND in combination with SCA and Calibra cured in self-curing mode.
Materials And Methods: Fifty-three restorations were placed in 38 patients in March and April 2006. No patient received more than two restorations.
Purpose: To assess the bond strength to dentin of an experimental adhesive and the proprietary resin cement used in different curing modes to lute ceramic disks of different thicknesses.
Materials And Methods: Empress II disks (Ivoclar-Vivadent) were luted to dentin using XP BOND (Dentsply [XP]) in combination with the proprietary self-curing activator (SCA) and cement Calibra (Dentsply [C]). Curing of the adhesive was induced either by mixing with the activator (activator, groups 3 to 6) or by light irradiation for 20 s (group 2).
Purpose: To retrospectively evaluate the long-term clinical performance of three types of fiber posts after a service period of 7-11 years.
Methods: 985 posts were included in the study: 615 Composiposts, 160 AEstethic Posts and 210 AEsthetic Plus Posts were placed into endodontically treated teeth. Four combinations of dentin adhesives/luting materials were used.
Purpose: To compare the clinical response of 6% hydrogen peroxide whitening strips and a 10% carbamide peroxide custom tray system under common daytime usage conditions, in an Italian dental research center.
Methods: Informed consent and baseline measurements were collected, and 43 healthy adults were randomly assigned to 6% hydrogen peroxide whitening strips (Crest Whitestrips) or the 10% carbamide peroxide custom tray (Opalescence 10%). The maxillary arch was treated twice daily for 30 minutes at-home.
Purpose: This study evaluated the 2-year outcome of post-and-core restorative procedures in endodontically treated teeth. The effect of baseline factors (tooth type, number of residual coronal walls, and type of definitive restoration) on restoration failure was assessed.
Materials And Methods: The consecutive sample design included 150 patients.
Purpose: The research evaluated the peroxide concentration whitening response following self-directed use of whitening strips over a 28-day period.
Methods: A randomized, double-blind, parallel group clinical study was conducted. 37 healthy adult volunteers were randomly assigned to one of three groups based on tooth color at screening: 1.
