Technique Tips: ContactPro Matrix System
One of the downfalls of sectional matrix systems lies with the ring. The ring is what provides the necessary tension placed between the teeth to achieve an ideal interproximal contact. As the ring goes through multiple uses, the separating strength begins to diminish, resulting in metal fatigue, which is the No. 1 reason ideal contacts are not obtained in direct composite restorations.
With the ContactPro Matrix System, Microbrush has solved this problem with a solution to the restorative dentist’s needs. ContactPro’s Memory Metal keeps the ring from fatiguing over time. Even after the autoclave process, the metal holds its integrity. The ring is also developed with soft silicone for adaptability to the tooth shape so it keeps a firm grip on the tooth but doesn’t pinch the patient when it is placed.
“The durability of the ring is in a league of its own. There is no other ring on the market that will give you consistent results day in and day out,” said Troy Schmedding, DDS. “The wide range of adaptability allows the soft silicone to adapt to any circumstance no matter what the situation.”
The ring’s unique shape was designed to allow for greater visibility in the working area and better access for light-curing. The secure fit along the gingival margin also provides better overall adaptation.
“The complete system provides a wide visible field as well as the ability to stack your rings. Quadrant dentistry is easily obtained with the use of these very stable and highly adaptable rings,” Schmedding said.
The ContactPro Ring can be paired with the coated or uncoated Smartbands for a snug fit at the gingival margin, the ContactPro Wedge, and DryTips for advanced moisture control for a successful Class II restoration.
