Successful Composite Resin Restorations - Part 2 of 2

Description:
Amalgam has been a durable successful dental restorative material; however this material has recently come under question due to its mercury content and disposal. Composite resin materials range from flowable to highly filled condensable type viscosities. There are many factors that influence the success of posterior composite resin restorations. This presentation will identify the factors that limit success (size, patient type, caries risk, shrinkage, curing light) and the materials that can be successfully used to restore posterior teeth. Beginning with flowable materials and their clinical application the presentation will discuss the open sandwich technique, use of flowable posterior restorations, sectional matrices and fluoride, calcium and phosphate releasing materials.

Gerald Benjamin - (9/10/2015 9:50 PM)

As a clinician who has placed all of my posterior restorations using rubber dam AND with a bulk cure technique since 1992, I feel confident in taking exception to the approach advocated in this video. 1. The prep should have all cavosurface margins beveled 2. The entire prep should be air abraded with a Danville Prep Star which is a high powered air abrasion unit 3. The prep should be bulk filled and completely carved to an ideal contour and occlusal height 4. A #2 sable brush should be used as the final carving tool to pull the resin over the cavosurface bevel (margin) so that in effect, there is no definite resin tooth margin. This means that there is no margin to stain or break down. 5. TWO high powered Ultradent curing lights should be used SIMULTANEOUSLY from the buccal and lingual to cure the resin for at least 20 seconds. Curing in this manner (bilateral transenamel illumination advocated by Paul Belvedere) controls polymerization shrinkage to the highest degree and uses shrinkage to our advantage instead of a disadvantage. The final 20 second cure is from the occlusal surface. We have 15 year restorations that show little to no marginal breakdown and no leakage down the walls. This technique results in a full and complete depth of cure.

The Cycle of Tooth Preservation Via Stress-Reduced Direct Composite Restorations Premium Member Content

The Cycle of Tooth Preservation Via Stress-Reduced Direct Composite Restorations
This lecture will provide clinicians with an overview of differing biomimetic protocols and techniques to predictably restore the anterior and posterior dentition using a minimally invasive approach. Increasing interest has been developed on “Life-like” restorations also known as biomimetic restorations. These are either porcelain or resin based restoration that can be performed on the anterior and posterior areas of the mouth. They may adopt both an indirect and a direct technique. The common characteristic is that they are low stressed and highly bonded restorations able to reproduce the functional and optical characteristic of the natural dentition.

Customize Your Composites For Your Patients Premium Member Content

Customize Your Composites For Your Patients
Today's composite resins have truly evolved to the point where you can several 'best' choice for any restorative situation. Using various case studies, this course will demonstrate the use of a family of low-shrinkage composites and proven techniques to provide many examples of the applications of different types of composites to provide excellent results. Additionally, we will discuss how to use the photography of these cases to create awareness to current, new, and potential patients through various marketing techniques.

Clinical Tips for Posterior Composites Premium Member Content

Clinical Tips for Posterior Composites
Despite the popularity of posterior composites, it is a topic that still creates questions and frustrations for many clinicians. Our goal is to place these restorations with ease and success to create long lasting results. We will discuss preparation design, material selection, matrices, and placement techniques. One of the most common questions I get is about predictably creating tight contacts, and we will look at several techniques to ensure this happens.

The Centripetal Build-Up for Composite Resin Posterior Restorations

The Centripetal Build-Up for Composite Resin Posterior Restorations
This paper introduces a new technique for creating Class II posterior composite restorations - the centripetal build-up. This technique replaces the lost tooth structure from the periphery towards the center of the cavity, thereby achieving better marginal adaptation to the gingival floor. Since overfilling is rare, rotary finishing is minimized. This method allows the creation of long-term aesthetic posterior composite restorations, while utilizing conventional auxiliary (ie, metal matrix bands…

Fatigue Resistance and Crack Propensity of Novel "Super-Closed" Sandwich Composite Resin Restorations in Large MOD Defects

Fatigue Resistance and Crack Propensity of Novel "Super-Closed" Sandwich Composite Resin Restorations in Large MOD Defects
To asses the influence of conventional glass ionomer cement (GIC) vs resin-modified GIC (RMGIC) as a base material for novel, super-closed sandwich restorations (SCSR) and its effect on shrinkage-induced crack propensity and in vitro accelerated fatigue resistance. A standard MOD slot-type tooth preparation was applied to 30 extracted maxillary molars. A modified sandwich restoration was used, in which the enamel/dentin bonding agent was applied first, followed by a Ketac Molar or Fuji II LC base, leaving 2mm for composite resin material. Shrinkage induced enamel cracks were tracked with photography and transillumination. Samples were loaded until fracture or to a maximum of 185,000 cycles under isometric chewing, starting with a load of 200 N and gradually up to a maximum of 30,000 each...
