First Impressions: February 2014

In First Impressions, George Freedman, DDS, gives readers a brief summary of products that have recently been introduced to dentistry, based on his clinical experience.

Zolar Photon Laser
Zolar Technology

For the better part of 2 decades, dental lasers were a fascinating but largely inaccessible technology for most dental practices. Lasers were too expensive and too complicated. Two parallel trends have helped to change this situation. The expansion of clinical indications for laser use within the dental practice has made this technology as essential as the dental handpiece. The contraction of the laser price point has helped to make it affordable for most practitioners. The most significant development in the past decade has been the introduction of the diode laser. Intuitive to install, easy to use, gentle and comfortable, and with little or no risk of thermal tissue damage, lasers have become part of the mainstream dental armamentarium. Zolar Photon Laser, from Zolar Technology, is an 810-nm, 3W countertop unit that is as clinically useful as it is easy to incorporate into practice. Indicated primarily for soft-tissue procedures, Zolar Photon Laser has a wide range of applications, including gingival reduction, soft-tissue crown lengthening, gingival troughing for impressions, gingivoplasty, implant exposure, fibroma removal, operculectomy, and excision of granulation tissue (among many others). The large LCD display clearly shows all the menu options that can be readily adjusted on the fly. More than 20 presets guide the dentist initially, and ongoing use quickly develops personal parameters that can be set in the memory. The Photon is light and readily portable and can operate on battery power alone for as long as 4 hours. The foot control can be wired or wireless. Rather than a key (that can be lost) for security, it uses a digital password. Zolar’s Photon Laser is an affordable, dynamic diode laser for the 21st century.

One Shot Uni-Layer Porcelain
Shofu

Many dental lab techniques are labor-intensive. One of the most time-consuming procedures at the dental laboratory has been the use of multiple powders to match a variety of shades and achieve esthetics. After the opaque was applied to the metal and baked, separate shades of cervical, body, and incisal porcelain powders of various colors and translucencies were used to build the ceramic over the opaque. Each powder step required a baking cycle, costing more bench time. Time at the laboratory translates very quickly into a higher cost for the crown, which must be passed on to the dentist and ultimately to the patient. Shofu’s One Shot Uni-Layer Porcelain is a new-generation ceramic material that streamlines the ceramic restoration process. The Opaquer Base is applied to the metal surface and baked. The selected shade opaque is applied over the base and fired. The full-contour buildup is then completed with the One Shot Uni-Layer Porcelain, which is followed by final firing. The opaque shape displays esthetically through the highly translucent uni-layer porcelain. The greater the depth of the unilayer, the greater the translucency, providing an ideal opalescence at the incisal and cusp tips. The full-contour buildup requires only one bottle of porcelain powder and just one baking cycle. The densely packed homogeneous material results in significantly reduced shrinkage (versus multiple firing cycle techniques), and the restoration can be completed in significantly less bench time with superior esthetic results. The One Shot Uni-Layer Porcelain, an extension of the popular Vintage MP and ZR ceramic product lines, is indicated for both PFM and zirconia restorations.

Imprint 4
3M ESPE

Imprint 4 VPS Impression Material Family
The ultimate test of an impression material is its precision. The task of impression material is to capture every minute detail of the hard and soft tissues in a moist environment. The accuracy of the impression material is the very foundation of the indirect restorative procedure. Even the slightest discrepancy at this early stage can sabotage the final restoration, often beyond repair. The practitioner can choose among many vinyl polysiloxane (VPS) materials; unfortunately, not all deliver a good balance of clinical properties, often requiring the sacrifice of one benefit to achieve another. Imprint 4, an impression material recently introduced by 3M ESPE, offers exceptional performance in many key areas that make it an excellent impression choice. Its proven surfactant, combined with an innovative wetting agent, brings a significant increase in hydrophilicity, present at the start of the mix and becoming more so during the setting phase. In fact, Imprint 4 shows the most hydrophilic behavior during the setting reaction, absorbing water, saliva, and blood plasma. A built-in mechanism induces self-warming, causing the material to warm to 37°C (98.6°F) in the mouth. This speeds up the hydrolization setting reaction of the VPS material, and hastens the setting in the mouth. The self-warming begins immediately after the working time. This accelerated intraoral setting is very convenient chairside. Imprint 4 also has a novel setting accelerator that achieves less intraoral tray time for the patient, and less waiting time. The reduced patient stress is welcome in every practice. This highly accurate impression material is available in a range of viscosities and a variety of work/set times in both cartridge and Penta delivery modes.

Imprint 4 Heavy Body and Regular Wash Materials Imprint 4 Super Quick Heavy Body and Light Wash Materials

GrandTEC
VOCO America

The necessity for reinforcing teeth occurs quite often in the dental practice. Splinting temporarily, or permanently, as part of orthodontics and periodontal therapy is quite common. The repair of tooth fragments or avulsed teeth after trauma is required all too often. Standard hybrid and nanohybrid composites lack the strength for these specific applications. With the introduction of GrandTEC by VOCO America, the resin-impregnated glass-fiber strands expand clinical treatment potentials by offering additional support for weak dentition, distributing occlusal loads through the fibers of the restoration and providing reliable foundations for common restorations. Its resin-impregnated glass fibers coalesce chemically with flowable composites, reinforcing and supporting the existing dentition and providing a semi-rigid mechanism for spanning edentulous spaces. It is indicated for orthodontic and periodontal splinting, post-trauma stabilization, the fabrication and/or reinforcement of provisional temporary bridges, the temporary replacement of extracted teeth to maintain the existing interdental space, the semi-permanent replacement of a missing tooth, and implant provisionals. GrandTEC’s clinical advantages include the following: pre-impregnated glass fibers (eliminating adhesive wetting), high adhesive strength, great flexibility and pliability, and compatibility with all light-cured dental composites. It can be used with both direct and indirect restorations and fades to invisibility within the restoration. The fibers improve the transverse strength of the restoration considerably and absorb functional stresses, greatly increasing the longevity of every application. The glass fiber strands are 55 mm long and 2 mm in diameter. They can be shortened as needed with fine-tip scissors and shaped with conventional composite instruments. The protective foil prevents contamination of the impregnated glass fibers, which should only be removed immediately before insertion into the patient’s mouth.

NANOCERAM-BRIGHT
DMP Dental USA

Important characteristics for a successful hybrid restorative material are superior ease of placement, restorative strength, and tooth-blending esthetics. However, there are many other parameters that contribute to the practitioner’s clinical achievements, and all of them impact on the selection of a particular product. NANOCERAM-BRIGHT by DMP Dental USA is a light-cured, nanohybrid composite formulated with a special blend of nano- and microfillers. The superior esthetics results from an advanced method for integrating the nanoparticles in the resin matrix. The nanoparticles have an average size of 20 nm, permitting an ultrarapid polish after polymerization and exhibiting very low wear in the long term. NANOCERAM-BRIGHT is indicated for both anterior and posterior direct restorations as well as direct veneers. Its excellent, nonsticky handling is complemented by its ease in sculpting with no slumping. Its particle size blending yields superior marginal integrity and eliminates microleakage, all the while minimizing postoperative sensitivity. Tooth interface longevity is further enhanced by low polymerization shrinkage and high flexural strength. The Composite filler contains a scientifically developed blend of opaque and translucent components to assure a normal vitality. It has enough capacity to mask darkness and yet enough translucency to offer a vibrant, natural appearance. NANOCERAM-BRIGHT’s chameleon-like properties, along with a comprehensive range of restorative tints, offer excellent shade matching for restorations that literally disappear. The ultrasmall filler particles make the finishing and polishing steps to a highly glossy surface easy and fast. Two kits are available: the introductory 4-syringe kit has shades A2, A3, A3.5, and B; while the 7-syringe kit includes shades A1, A2, A3, A3.5, B2, B3, and C2.
