Elastic matrix system

An apparatus for use when performing a dental restoration process, comprising:

• a restoration band having an elongated body between a first end and a second end, the elongated body having a top edge and a bottom edge and conforming to a circular shape configured to surround a tooth;
• an upper circular rim of elastic material that has a first channel, wherein the top edge of the restoration band is positioned in the first channel, an expansion and contraction of the upper circular rim causes the restoration band to uncoil and coil, and the uncoiling and coiling of the restoration band causes a first diameter of the restoration band along the first channel to expand and contract;
• a lower circular rim of elastic material that has a second channel, wherein the bottom edge of the restoration band is positioned in the second channel, an expansion and contraction of the lower circular rim causes the restoration band to uncoil and coil, and the uncoiling and coiling of the restoration band causes a second diameter of the restoration band along the second channel to expand and contract;
• and
• an elastic sleeve that attaches the upper circular rim to the lower circular rim with the restoration band extending therebetween the upper circular rim and the lower circular rim, wherein a portion of the restoration band passes through the elastic sleeve.
