Background and Aim: Several methods are available for intraoral repair of chipped porcelain restorations by composite resin. Also, there is still controversy regarding the best method of porcelain repair in terms of bond strength and cost effectiveness. This study aimed to compare three methods of porcelain surface treatment on shear bond strength (SBS) of composite to porcelain. Materials a...
The oxidation and porcelain fusion characteristics of noble alloys containing a variety of minor oxidizable elements, including Cu, Sn, In, Ga, Mn, and Fe were investigated. Four porcelain alloys systems: a Pd-base alloy (Naturelle}, two Pd-Ag-based alloys (Jelstar and Acclaim}, and a high Au-alloy (SMG-3) were examined by scanning electron microscopy and energy dispersive spectroscopy after be...
AIM The present case report described the use of contact lens of thin porcelain veneers as a restorative therapy to solve anterior teeth disharmony. BACKGROUND Fragments of thin veneers are minimally invasive restorations with little or no dental preparation and present thickness ranging from 0.2 to 0.5 mm. They are used in case of diastema closure, small changes of teeth, color and restorati...
Metal-ceramic restorations are widely used in dentistry with a high degree of general success. However, fracture of these restorations does occur and usually frustrates both the dentist and the patient. Objective: This literature review discusses the factors that may lead to the fracture of these restorations whether they are tooth-supported or implant-supported with the aim of making dentists ...
In order to ensure a functional, aesthetic, and long-lasting porcelain result, clinicians need to anticipate the strengths and limits of the restorative material, as well as the specific requisites of the presented case. As flaws in preparation design can have significant and detrimental effects on the final result, clinical comprehension of the dimensions and limitations during this step is of...
OBJECTIVE This study aims to determine whether bruxism and the use of occlusal splints affect the survival of porcelain laminate veneers in patients treated with this technique. MATERIAL AND METHODS Restorations were made in 70 patients, including 30 patients with some type of parafunctional habit. A total of 323 veneers were placed, 170 in patients with bruxism activity, and the remaining 15...
STATEMENT OF PROBLEM Production of a ceramic dental restoration that matches a target shade is dependent on porcelain thickness. Even when adequate porcelain thickness exists, clinical shade matches are difficult to achieve. PURPOSE This study predicted the thickness of dentin porcelain required to obtain a clinical shade match (</=3 DeltaE units) for a variety of dental porcelain systems and...
Porcelain aorta is a harbinger of widespread atherosclerotic process and its identification may be associated with higher cardiovascular and surgical mortality. Patients with porcelain aorta requiring cardiac surgery need specific alterations in approach to the surgery especially with regard to aortic cross – clamping. However, its association with systemic inflammatory bone and joint disease i...
Porcelain gallbladder or calcified gallbladder is a rare entity and is considered as the end stage of chronic cholecystitis. This disease is rarely diagnosed preoperatively and usually mimics carcinoma gallbladder. Hereby, we present a rare and interesting case of porcelain gallbladder that was diagnosed preoperatively and managed by cholecystectomy. How to cite this article: Goel A, Agarwal A,...
