Good diagnostics and preparation key to successful restoration
SAN ANTONIO ? Good diagnosis and preparation with the right tools are the keys to a good restoration, according to a speaker at the Dental Learning-sponsored event, 'Updates in Contemporary Dentistry', held here.
G. Franklin Shull, Jr., DMD, who has a private practice in Lexington, SC, addressed a group of about 200 dentists and noted that diagnosis with digital radiographs, photography and magnification, combined with using the right handpiece, bur, and prep materials, can facilitate an optimal restoration. He specifically noted the Kavo handpiece line, and Schick?s line of digital sensors which provide images on-screen in real time, as assisting clinicians with diagnosis.
Shull stated that nanotechnology has made increased filler concentration possible, paving the way for stronger composites with better wear characteristics, improved esthetics and the ability to be used for anterior and posterior restorations. He discussed the VOCO America products, and encouraged attendees to look at their studies regarding volumetric shrinkage and polishability.
?If you are looking for a new all?purpose composite, consider one in the nanofilled category,? Shull said.
Shifting gears to adhesive systems, Shull noted that there are several options, including multibottle total-etch, multibottle self-etch and all-in-one self-etch. Total-etch is still the standard however many dentists are having success with self-etching systems. If you are in the market for a new self-etch adhesive be sure you know if it can be used with all restorative types. Shull stated that the all-in-one from VOCO can be used with direct and indirect restorations.
Shull noted that it is important to clean the prepared tooth of all debris before etching, and said he uses 2% chlorhexidine gluconate. He said that he uses Gluma, or G5, to rewet after etching and before placing dentin bonding agent for direct composites. Studies demonstrate this technique does not decrease bond strength. He encouraged attendees to use a rubber dam during composite resin procedures.
He said that many dentists opt to use VOCO America?s Grandio, the universal light-curing nanohybrid restorative that provides low shrinkage (1.57% by volume) and high transverse strength. According to VOCO America, this is due to its composition of 87% fillers by weight and 30% to 50% less resin compared with standard microhybrids. Dr. Shull offered this pearl for those who use Grandio, noting, ?When cured, this composite is very hard and after finishing I use a porcelain polishing system for a very high luster.?
