ABSTRACT Objective: To evaluate the marginal gap (MG) and absolute marginal discrepancy (MD) of full ceramic crowns with two finish line designs, shoulder and chamfer, using microcomputed tomography (micro-CT) before and after cementation. Materials and Methods: Sixty extracted human maxillary premolar teeth were divided into two groups based on the finish line design: Group I: 90° shoulder and Group II: 135° chamfer. The specimens were further grouped based on the type of full ceramic crown they received: Group A: Feldspathic Cerec inLab ceramic system, Group B: Cerec inLab aluminum oxide cer

Abstract:

Different high-strength, all-ceramic restorative systems are available for the restoration of endodontically treated roots. To date, many studies on fracture strength and fracture pattern have been conducted. Most of these studies focused on investigating stress distribution in the root dentin of abutment teeth restored with a post and core system. The objective of this study was to evaluate, by means of the finite element analysis, stresses induced in an endodontically treated maxillary central incisor that was restored with different all-ceramic systems during contacts with the antagonists.

All studies agree that glazing can produce a smooth porcelain surface, but although the glaze is an important factor in esthetics, with respect to light reflection, it can frequently change the color value of the restorations, reflecting more light than the natural teeth, thus creating an artificial effect on these restorations. A number of more recent studies have suggested that a polished surface may be as acceptable as a glazed surface. Many ceramists prefer polishing instead of glazing to control the surface luster.

Crowns were cemented using a universal dual-curing cement (G-Cem One, GC) with two polymerization protocols: (G1) microbrush excess

Abstract:

Fiber reinforcement was introduced to clinical dentistry for the first time in the 1960s when investigators attempted to reinforce polymethyl-methacrylate dentures with glass or carbon fibers. It has recently been shown that crowns, bridges and posts made of FRC can be used successfully in dental practice and on the basis of marginal adaptation they are more acceptable than conventional metal ceramic crown. A prospective comparative cross-sectional study was performed involving 60 patients who attended in the out patients department of Prosthodontics, Faculty of Dentistry, BSMMU during the per

INTRODUCTION: No studies on the marginal gap or internal fit of crowns have reported the effect of non-axial seating which may often occur inadvertently clinically. AIM: Therefore this in vitro study sought to investigate the off-axis seating of CAD/CAM crowns and its effect on the marginal gap and internal fit. METHOD: A standardised crown preparation on a typodont tooth was used to design and mill 30 crowns with a flat occlusal surface. Ten Zirconia (Dentsply Sirona, Germany), 10 Enamic (Vita, Austria), and 10 Brilliant Crios (Coltene, Switzerland) crowns were milled, Ave of each milled with

Background and Objectives: The report describes a technique using a diagnostic mock-up as a crown-lengthening surgical guide to improve the gingival architecture. Materials and Methods: The patient’s primary concern was improving her smile due to her “gummy smile” and short clinical crowns. After clinical evaluation, surgical crown lengthening accompanied by maxillary central full-coverage single-unit prostheses and lateral incisor veneers was recommended. The diagnostic mock-up was placed in the patient’s maxillary anterior region and used as a soft tissue reduction guide for the gingivectomy

Abstract:

Amelogenesis imperfecta refers to a group of rare, inherited disorders characterized by abnormal enamel formation. Patients mainly seek solution for unesthetic appearance caused by the condition. As prosthetic rehabilitation is essential for esthetics and function an interdisciplinary approach is often needed for restoration of health and its long-term maintenance. A multidisciplinary approach was mandatory for the management of this case. Short clinical crowns were present in all quadrant which made it difficult to achieve adequate retention and resistance forms for tooth replacement. In all

Post endodontic treatment, it is necessary for coverage of the treated teeth, and full crowns are considered to be the best option for the same. Preformed crowns for primary molars are available in many sizes and materials to be placed over decayed or developmentally defective teeth. They can be made completely of stainless steel, stainless steel with a white veneer cover or made wholly of a white ceramic material when aesthetics is concerned.

Measurements were made of the fit of gold-alloy full-crown castings produced with dry ceramic ring liners. When used with vacuum investing, these liners absorb relatively large amounts of water from the investment mix (thereby reducing its original W/P ratio) and then function as wet liners, thus increasing the investment's potential expansion and giving castings which are consistently larger than when air investing is used. With four of the five liners tested, investing in air produced many castings which were unacceptably undersized (inaccuracy worse than -0.2%). The fifth liner, an industri

Abstract:

Attrition of natural teeth is a continuous process and can occur in any natural dentition. As the cusps of natural teeth are worn, masticatory efficiency and the biological stomatognathic stability are affected. Nature compensates the wear of teeth by supra eruption of the teeth, which, when further worn initiates a chain reaction. As time progresses, the teeth expose roots while the gingiva recedes. In such patients, the choice of fixed partial denture becomes tricky because when tooth preparation is done on the roots, the probability of over reduction is more. An elderly male reported for tr

A ceramic onlay restoration is a more conservative treatment than full-coverage crowns for endodontically treated teeth (ETT); thus, it helps preserve the tooth structure. Deep margin elevation (DME) is a method to relocate subgingival margins into a more coronal position with resin-modified glass ionomer (RMGI) or direct composite resin before the cementation of the indirect restoration. A 33-year-old male was referred to restore two ETT (teeth N. 46 and 47) with extensive coronal defects extending subgingivally between two teeth.
