Abstract Objective The unavoidable extraction of teeth in the esthetic area can be overcome through different treatment modalities. Recently, immediate implants appeared as a minimally invasive approach to resolving these cases; however, implant loading is not always possible or indicated. In cases, an innovative customized healing abutments could used preserve soft tissue contour, eliminating need for reopening surgery and use provisional restorations condition mucosal contour. Clinical...
Question: What is the best surface conditioning protocol for durable adhesion of resin-based materials to glassy matrix ceramics? Answer: Glassy ceramics, also known as silicabased are typically reinforced with feldspar, leucite, fluormica glass or lithium disilicate. Glass ceramics acid sensitive when etched hydrofluoric gel and they respond well adhesive bonding techniques where silanization resin applications performed. In such more pronounced roughness can be obtained increase in amount...
This study evaluated the influence of different aging times on color stability zirconia that is either veneered or not by ceramic.Fifteen disks (3Y-TZP) were produced (12.0 mm in diameter and 1.0 mm-thick). Five (G1) did receive veneering ceramic layer; 5 (G2) with a layer other (G3) 1.5 mm. The L*a*b* coordinates (T1) measured spectrophotometer. subjected to an accelerated protocol for 1 hour (T2), 2 hours (T3) 4 (T4). Measurements made after each time. Differences (ΔE00), lightness (ΔL'),...
Abstract Objective Evaluate the adhesive behavior of conventional and high‐translucent zirconia after surface conditioning hydrothermal aging. Materials Methods Conventional (ZrC) (ZrT) specimens were divided into six groups: without treatment (ZrC ZrT), air‐borne particle abrasion with 50‐μm Al 2 O 3 sized particles (ZrC‐AO ZrT‐AO), tribochemical 30‐μm silica modified (ZrC‐T ZrT‐T). Zirconia treated using an MDP‐containing universal bonded to two resins blocks luting cement. Microbar...
Preventive and regenerative techniques have been suggested to minimize the aesthetic functional effects caused by intraoral bone defects, enabling installation of dental implants. Among them, porous three-dimensional structures (scaffolds) composed mainly bioabsorbable ceramics, such as hydroxyapatite (HAp) β-tricalcium phosphate (β-TCP) stand out for reducing use autogenous, homogeneous, xenogenous grafts their unwanted effects. In order stimulate formation, biodegradable polymers...
ABSTRACT Objective To evaluate the color of a bis‐acryl resin after polishing, aging, and colorants. Materials Methods From 140 disks obtained, 35 were not polished (NP), with 3‐μm (3P), 3‐ 1‐μm (1P), 3‐, 1‐, 0.5‐μm sized particles (05P). Five each group thermocycled for 20, 100, 200 cycles. Sixty kept in beverages (tea, wine, coffee) four immersed 24 hours, week, month. The coordinates L*a*b* measured differences analyzed by ANOVA. lightness, chroma, hue evaluated repeated measures...
Abstract Background Since color measurements are relative, the discrepancy among different instruments is alarmingly high. This multicenter study evaluated effectiveness of instrument calibration and inter-instrument harmonization spectrophotometers with same optical geometry using tooth-colored, translucent dental materials. Methods The coordinating center (CC) spectrophotometer was calibrated NPL Ceram Series II set. Two sets 10 specimens, labeled 1 to I X (10 mm in diameter thick), were...
Evaluate the color and translucency of a nanoceramic resin subjected to hygiene practices immersion in coffee over time.
This study investigated the effect of porcelain firing on misfit implant-supported frameworks and analyzed influence preheat treatment dimensional alterations.Four external-hex cylindrical implants were placed in polyurethane block. Ten screw-retained prostheses cast Pd-Ag using 2 procedures: (1) control group (CG, n = 5): segments laser welded; test (TG, segments, preheated, welded. All samples subjected to simulate veneering firing. Strain gauges bonded around implants, microstrain values...
This study evaluated the impact of tooth shade on differences in color (∆E), lightness (∆L), chromaticity coordinates a*/b* (∆a and ∆b), transmittance degree fluorescence CAD/CAM leucite based ceramic (LBC). Ten disks were fabricated LBC; Empress CAD, A2, thickness 1.5 mm eight resin-nano-ceramic (RNC; Lava Ultimate) different colors to simulate variations substrate shade. The associations LBC with substrates analyzed a spectrophotometer; ∆E, ∆L*, ∆a*, ∆b*, measured calculated. Fluorescence...
Currently, minimally invasive restorations could be made in dentistry applying adhesive materials and adhesion principles to the dental structures. Following this philosophy, endodontic interventions have been avoided largely, preserving hard tissues, maintaining vitality. Advances biologically favorable bioactive enabled clinicans induce repair regeneration of tissues. Such are primarily used for pulp protection cementation indirect restorations. This review highlights current available,...
The aesthetics of a dental restoration depends on the chosen material, anatomical form, surface texture, translucency and color. This means that, to accurately reproduce appearance natural tooth, considering patterns reflection absorption light is not an easy task (Knispel, 1991; Chu et al., 2004). Ceramics have been widely used in dentistry because their ability provide excellent cosmetic results that mimic teeth. They are biocompatible, allow adequate transmission light, they exhibit good...
