iTero |
|||
Anyone who has experienced a dental impression from a patient’s perspective realizes that it is not inherently a comfortable procedure. On the other hand, dental professionals know from experience that traditional impression techniques are not always as accurate and precise as they should ideally be. While impression materials and techniques have improved by leaps and bounds over the past quarter century (and in particular, during the last decade), conventional procedures are increasingly being superseded by imaging technology. Dentists, lab technicians, and patients can readily foresee significant benefits in making traditional trays and materials obsolete. Cadent’s iTero is an integrated digital impression system that serves as the link between dentists and laboratories. It is powered by a proprietary imaging technology that allows the dentist to take a 3-D digital scan of the patient’s mouth, to make any necessary adjustments, and then to electronically transfer the data file to the lab technician, who in turn fabricates a precise final restoration for the patient. The dentist-technician data transmission is virtually instantaneous, eliminating the costs of impression materials, additional chair time, packaging, transportation, etc. (This does not even include the advantages of greater precision, eliminating costly remakes and adjustments.) For the patient, the iTero digital impression takes less than 2 minutes and is painless, and the on-screen images are exciting. For the dentist, iTero does not require coating the teeth with a powder, and it is easy to learn and adapt to the practice. The margins can be readily seen from without and within, manipulating the digital impression image in all directions, eliminating clinical uncertainty. iTero’s cutting-edge technology also positions the practice very favorably.

Grandio Seal |
|||
The profession has long been aware that pits and fissures on otherwise healthy tooth surfaces are very caries-prone areas. The sealing of pits and fissures to prevent their colonization by cavity-forming bacteria has been a part of standard prophylaxis for some decades. The selection of a fissure-sealing material has always been a dilemma–whether to opt for a flowable composite with better physical properties (which on the down-side, may not be flowable enough to penetrate the more inaccessible areas of fine pits and fissures) or to choose a pit and fissure sealant that has excellent penetration properties (but exhibits greater polymerization shrinkage and is likely to wear quite rapidly). VOCO America has introduced a new sealant material that combines the best properties of both options. Grandio Seal is a nano-fissure sealant that has a 70% (by weight) filler content that offers low polymerization shrinkage, high abrasion resistance, and high transverse strength. The unique filler composition also offers the flowability of traditional sealants, without the “drip,” and a defined pressure point on the syringe for optimal flow. The extrathin metal applicator can access the tightest of fissures. Fluoride-releasing Grandio Seal is manufactured in a readily visible white opaque shade. It is indicated for pits and fissures in younger and older children as well as in adults who tend to have a higher caries risk. (Adults often tend to be overlooked for this simple yet effective and highly preventive service.) The blending of simplified application and superior wear properties utilizing the nano-particle fillers has eliminated the guesswork for the dentist and hygienist; uncompromised fissure sealing is now possible.

Variolink Veneer Esthetic Resin Cement |
|||||
As technique-sensitive as crown and bridge cements are, porcelain veneer cements represent an even greater clinical challenge. Most crowns hide the underlying resin cement completely. Veneer cements, however, are readily visible through the restorations and are expected to contribute to the overall aesthetics of the completed case. Veneer cements should be opaque but not too opaque, translucent but not too translucent, strong yet easy to remove, color stable, and light-curable. An updated reformulation of Ivoclar Vivadent’s popular Appeal Resin Cementation System has resulted in the Variolink Veneer Esthetic Resin Cement. There are 7 light-cured value shades; the medium value (or 0) cement is quite translucent, while the lower values contribute a yellowish tinge to warm the restoration, and the higher values increase the apparent brightness. The new system adds some intensity to the +3 and -3 shades. Thus, the dentist has the clinical ability to make the smile “warmer” or to “kick it up a notch” on the brightness scale simply by using the appropriate resin. Variolink Veneer has an amine-reduced formulation that offers long-term, predictable color stability to restorations. The removal of excess cement is also far easier than previously (when it involved high- and low-speed cutting tools, etc). After placing the Variolink Veneer-loaded restorations onto the teeth, tack the veneers into place and fleetingly pass the curing light over the marginal surfaces. Excess cement, now in a gel consistency, can be readily peeled away, revealing sealed margins and reducing polishing time significantly. Variolink Veneer uses a microfill technology to reduce wear and increase polishability and increase bond strength and translucency.
