Geriatric problem solving with adhesive dentistry, using the Contour Strip and direct composite placement.

The ability to create periodontally sound gingival and non-staining or plaque retaining interproximal margins on spacious carious lesions is a daunting challenge in many situations. The case as presented will illustrate the use of a unique matrix system, The Contour Strip from Vivadent, which will encompass the entire outline margins of the upper right lateral incisor of an elderly patient. The age of the patient has no bearing on the use of the technique, but merely reenforces the value of the system in all other situations mimicking a similar restorative obstacle. The use of this custom shaped matrix band, eliminate the free-hand placement and then the laborious creation and finishing of the restoration. LEARNING OBJECTIVES: After reading this paper the reader will understand the manipulation and use of a new labial matrix band which can totally surround the gingival and proximal margins of any anterior and pre-molar teeth. TECHNIQUE CONSIDERATIONS: There are four rules to follow when using adhesive dentistry: Proper preparation of tooth surfaces, both dentin and enamel through mechanical and/or chemical means. Creation of matrix formed molds. Injecting all resins, from the lowest to the highest viscosity. Polymerizing thoroughly through trans-enamel polymerization thus controlling shrinkage.

Contemporary posterior direct composites using state-of-the-art techniques.

The dental team that wishes to increase the use of posterior composite restorations will benefit greatly by the information and step-by-step techniques found in this article (Fig. 7A and B). Starting with a clean slate and analyzing the chemistries, the physical nature of resin-based composites, and the systems and devices available to use them most efficiently, the author presents a state-of-the-art, evidence-based technique. By cutting out many of the steps that follow traditional methods with traditional materials and instruments for the placement of silver amalgam, sophisticated practitioners will readily understand the reasoning behind this successful, contemporary, direct posterior composite technique (Fig. 8A-J).

Single-sitting, fiber-reinforced fixed bridges for the missing lateral or central incisors in adolescent patients.

Many materials, methods, and techniques for the reinforcing of composites to bond a pontic onto abutment teeth have been tried and promoted. In this article, the author examines the use of fiber reinforcement in fixed bridges, describing the various steps performed by the dentist during the procedure.

Evaluating the effect of glove coating on the shear bond strength of porcelain laminate veneers.

Gloves have become a standard tool in dentistry due to infection control concerns. But the starch powder with which many of these gloves are coated may contaminate surfaces on contact, creating potential problems during adhesive procedures such as the placement of porcelain veneers. The authors studied the powder's effect on the strength of the shear bond of etched porcelain to etched human tooth enamel and compared it to the effect of a powder-free polymer glove coating. While the starch coating led to a statistically significant decrease in shear bond strength, the powder-free coating produced no significant decrease in strength.

Over a decade of success with Heliomolar.

In developing improved dental materials and application techniques high standards and goals are set by the clinicians and the manufacturers. This article summarizes the prerequisites and desirable qualities required of composite resins for long-term process. A particular composite has demonstrated predictable and consistent long-term results and has established its place in quality dentistry. The applications for this composite resin are outlined in a clinical procedure. Its anterior/posterior universality is recognized. Several pre- and postoperative examples, in function for up to 12 years, are used to illustrate the results.

Negative effects of powdered latex gloves in clinical dentistry.

With the advent of CDCs "universal precautions" and OSHA's bloodborne pathogen standard, the number of health-care workers wearing latex gloves has increased dramatically in the law few years. Reports of irritation, contact, and allergic reactions to powdered latex gloves in both medicine and dentistry are on the rise as well. However, other problems related to powdered gloves and their effect on clinical dentistry are just beginning to be addressed. One recent study demonstrated that the starch used as a lubricant on latex rubber gloves significantly reduced the shear bond gloves significantly reduced the shear bond strength of etched porcelain to etched enamel with a resin adhesive system by nearly 40%. Question also arise as to the proper handling of dental implants and the effect that powdered gloves may have on their success based on the negative effects of post-surgical foreign body granulomas reported in the medical community.

[New method for preparation of fiber reinforced temporary crowns and bridges]. / Eine neue Methode zur Herstellung faserverstärkter temporärer Kronen und Brücken.

In many situations there is an indication for the creation of a long term, functional, chairside temporary bridge or crown. Utilizing a cold-light dual-cure composite material, Dual cement, reinforced with Polyethylene fibers, an excellent, strong bridge or crown will result. The technique is as follows: replace missing tooth/teeth by hand shaping Helioprogress composite restorative to a pontic-form. It will stay in place firmly enough while the Bluephase "mold" impression is taken. Then prepare teeth as they will be needed (no undercuts). By closing their mouth patients coat their teeth with saliva which will act as a separator. Now three fiber bundles in proper length will be used to reinforce the dual cured composite. Wet the fibers with Heliobond to saturate the bundles and wet each filament in the bundles. Examine the internal portions of the Eos Bluephase impression and alter by cutting if necessary to create an acceptable negative tooth shape. Cut a relief hole in the deepest corner of each of the teeth to be duplicated, with a No 4 round bur which will allow the trapped air to escape as the filled mold is repositioned over the teeth to form the temporary restoration. The carefully mixed Dual cement is now pressed in a small amount into each of the preparations involved.(ABSTRACT TRUNCATED AT 250 WORDS)

[A metal-free single sitting fibre-reinforced composite bridge for tooth replacement using the EOS-System]. / Vom Zahnarzt ausserhalb des Mundes gefertigte metallfreie, lichtgehärtete Composite-Faser-Brücken. Eine neuartige Technik mit neuen Materialien.

This paper intends to introduce a technique for a one sitting fixed resin bridge with excellent aesthetics and longevity. Techniques using denture teeth or a crown portion of the patient's own teeth have already been presented by many authors. But they all have been unpredictable and their longevity could not be assured. The addition of resin fibre filament to create a flexible reinforcement at the pontic-abutment interface gives added strength to the acid etch bond between pontic and abutment. Reinforcing systems such as metal wires, woven screen, metal bars with retentive holes, glass fibres, silk and resin fibres have been used with varying results. The original composite reinforced bridge using resin fibres was done by the author with Kevlar 49 in February of 1981, replacing both upper central incisors using only the lateral incisors on a 22 year-old female. This four-unit-bridge is still in function (end of 1989) and has never been replaced or repaired. Since then improvements have been made and the following technique has evolved. 360 fibre reinforced "Belvedere bridges" have been placed to date with a success rate of 98%. One of the improvements is the use of another fibre, which has extremely high tensile strength: it is a polyethylene fibre, colourless and six times stronger than steel.
