BACKGROUND Although composite restorations are really valuable for esthetic zones, they have shown less longevity rather than amalgam restorations. Since it may be related to the method used for curing the composite, postcuring could increase the degree of conversion and result in more long-lasting composite restorations. This study was planned to evaluate the effect of two different postcuring...

The purpose of this study was to evaluate the flexural strength of a direct composite, for indirect application, that received heat treatment, with or without investment. One indirect composite was used for comparison. For determination of the heat treatment temperature, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were performed, considering the initial weight l...

Provisional restorations are fabricated to protect the prepared tooth structure during the period between tooth preparation and insertion of the definitive restoration. These restorations are also referred to in the literature as interim, temporary, or provisional restorations (prostheses). Such restorations should be uncomplicated and inexpensive to fabricate in a short period of time. Several...

Submit Manuscript | http://medcraveonline.com Teeth presenting diastema and misalignment are a common finding in the anterior maxillary dentition, and this fact can strongly affect the appearance of a smile, besides being displeasing for the patients.1 The current literature suggests several approaches for the correction of diastemas and misaligned teeth, such as orthodontic intervention, direc...

UNLABELLED Although the literature has provided clinicians with some awareness of restorative material alternatives, such as laboratory-processed composite resin, these systems are not yet fully understood and implemented in daily practice, despite their benefits to dental patients. Whereas part I highlights treatment planning, preparation design, and impression making for an indirect resin onl...

OBJECTIVE This experimental in vitro study compared marginal adaptation of indirect composite, glass-ceramic inlays and direct composite. MATERIALS AND METHODS Seventy-five recently extracted human molars were randomly divided into three groups (n=25) and mesio-occluso-distal cavities with the same dimensions were prepared in the teeth. Indirect composite and glass-ceramic inlays were fabrica...

introduction: before placing or cementing a restoration into a cavity preparation, the clinician must decide whether a cavity base, liner or a protective cavity sealer should be placed. while this seems simple, the decision is complicated by an ever-increasing number of products available. in addition, the clinical success of an indirect restorative procedure depends, to a great extent, on the ...

Finite element analysis (FEA) was first used in Dentistry in the 70’s to replace photoelasticity tests. Since then, many researches have been developed by association of dentists and engineers, using 2D models. Because of the development of new image acquisition techniques and the development of technical design program the use of 3D models has increased. It is difficult to analyze the mechanic...
