To evaluate the marginal discrepancy of monolithic and veneered all-ceramic crown systems cemented on titanium (Ti) zirconia implant abutments.Sixty customized abutments for a maxillary right central incisor were fabricated Ti (n = 30 each) an internal-connection system. All-ceramic crowns using following 10 per group): with computer-aided design/computer-assisted manufacture (CAD/CAM) lithium disilicate (MLD), pressed (PLD), or CAD yttrium-stabilized tetragonal polycrystal (Y-TZP). The...

Abstract Objectives To assess the internal accuracy, mechanical behaviour under static load and screw loosening before after cyclic loading of implant‐supported crowns restored with original components or two compatible non‐original brands. Materials Methods Sixty‐three dental implants were divided into three groups ( n = 21 each): Group 1 used components, 2 3 components. Internal accuracy was measured throughout a cross section sample 8) using scanning electron microscopy SEM ) to evaluate...

To evaluate the effectiveness of intraoral scanning with identical multiple implant scan bodies (ISB) using customized over body rings (COR) as an auxiliary system.Six printed different diameters and shapes were attached at levels to each ISB edentulous mandibular master model. The model was scanned scanner (Primescan CEREC) until valid digital models for COR group (n=10) unmodified (UN) obtained. total times number rescans required registered. assess differences between efficiency Student...

The aim of this study was to evaluate the marginal accuracy and mechanical behavior implant-supported crowns restored with original stock abutments nonoriginal computer-aided design/computer-assisted manufacture laser-sintered abutments.A total 26 implants were divided in two groups (n = 13 each) as follows: connected (OS) (LS). Of these, 10 samples cross-sectioned measure under a scanning electron microscope. In addition, 16 used behavior. Two tests performed: (1) static load (2) dynamic...

The aim of this study was to evaluate the survival and compare appearance different mechanical biological complications, in screw-retained cemented-retained single-tooth implant-supported restorations localized molar mandibular region, over a period 1 4 years.A retrospective carried out with total eighty restorations, which were placed patients for prosthetic rehabilitation molar. Forty rehabilitated restoration other forty restoration. presence following complications recorded both types...

The complex anatomy of dens invaginatus makes access cavity to root canal system difficult, which has an impact on the prognosis these teeth. A novel technique, based new technologies, is proposed make conservative and guided with minimal dental structure lost.This case report shows retreatment endodontic surgery a type II in left lateral upper incisor previously treated was affected by chronic apical abscess fracture. Cone Beam Computed Tomography performed better diagnosis anatomy. An...

This report describes the case of an edentulous patient with atrophic maxilla and severe class III malocclusion. Prosthetic rehabilitation was performed using CAD/CAM techniques for manufacturing implant-supported overdenture horizontal insertion. A vestibulo-lingual insertion is a precision prosthesis fixation system affording good fit between primary secondary structure. Both structures exhibit passive adjustment. treatment option requires same number implants as fixed dentures. The...

The gingival thickness seems to have an important role in different dental treatments. There are methods of quantifying this thickness, but it is not known which them can be the most effective. objective assess accuracy two for measurement: transgingival needle probing (TGNP) and tension-free caliper (TFC) vitro model, by comparing with direct physical measurements (reference standard).Gingival (GT) was evaluated 27 female pigs four implant sites 1, 2 3mm from margin three methods: 1) 2) 3)...

This clinical case report describes the rehabilitation of central incisors with veneers in a patient gingival asymmetry. The teeth were prepared without finish line, applying BOPT concepts to correct asymmetry, and obtained harmoniously integrated restoration optimal periodontal health.Biologically oriented preparation technique (vertical or "feather edge" preparation) was used obtain symmetry. Teeth horizontal line achieve emergence, soft tissue adaptation stabilization, while maintaining...

To compare the effectiveness of different methods fractured screw fragment retrieval from dental implants, comparing a conventional method (use an exploration probe and ultrasonic tips) with two mechanical kits.One hundred thirty-five screws in implant internal connections were to test three methods: use explorer tips (group CE), extraction kit guide cylinder MK1), without MK2). Extraction success times for each method, as well relation fracture depth-coronal, middle, or apical-were analyzed...

Early restoration of the masticatory function, phonatory and aesthetics is some current goals therapy based on endosseous implants.Facing classic protocols implant insertion, which recommend a period several months between extraction placement, alternatives have been developed that demonstrate immediate placement after tooth permits adequate osseointegration, even in those cases where there periapical disease.The implants possibility aesthetic requirements are high.This article presents case...

An intraoral digital scanner in combination with specialized three-dimensional surface analysis software monitors volumetric changes to soft tissues or dental restorations.This technology can evaluate the success of a specific technique medium-or long-term clinical outcomes both and research situations.This article describes how this was used provide immediate chair-side data without help laboratory support.
