Clinical Guide: Class II Restoration on a Mandibular Second Premolar
There are two things dentists seem to always be striving to improve: speed and quality. With cases requiring a sectional matrix system being so common, one area where many clinicians look to save time and boost results is with the sectional matrix system they choose.
For Dr. Brett Richins, the case below perfectly showcases how the Halo™ matrix system enhances his abilities. “The Halo matrix system makes my Class II restorations faster and improves the final result,” says Dr. Richins. “I love the contour of the matrix bands and the way the tines adapt to the anatomy of the teeth. My contacts and marginal ridges have never been better.” He says time saved during restorations is the best part about using the Halo system. “I almost never need to remove flash or modify the occlusal embrasure. I can tell that the Halo system was designed with both the patient and the clinician in mind; it achieves great
results and is easy to use.”
1. Do preparation on tooth #45 (mandibular right second premolar) with caries removed.
2. 4.5 mm Halo™ band placed using Halo tweezers to hold the occlusal tab.
3. Small Halo wedge placed from the buccal using Halo tweezers.
4. Halo universal ring in place. Ready to begin restoration.
5. Check adaptation of band. Burnishing is typically not required but can be done if needed in challenging cases to ensure an adequate proximal contact.
6. Ultra-Etch™ etchant applied for 15 seconds on dentin and cut enamel.
7. Peak™ Universal Bond adhesive scrubbed into dentin and painted onto enamel for 10 seconds using Inspiral™ Brush tip.
8. Thinned/dried for 10 seconds using 1/4 to 1/2 air pressure. Preparation appeared shiny, and air thinning no longer produced visible movement of the resin. Cured for 10 seconds using the VALO™ X curing light.
9. Placed Transcend™ composite Universal Body shade in layers 2 mm or less.
10. Minimal finishing required after immediate removal of Halo matrix system.
11. Finished with the Jiffy™ Naturalpolishing line.
12. Completed restoration with anatomical contact and sole use of Transcend composite’s Universal Body shade.
Transcend universal composite enables clinicians to push beyond traditional limitations and redefine the standards of dental craftsmanship. With its unrivaled blend of technology and performance, Transcend composite marks a new era of esthetic dentistry.
