The use of a high-clarity matrix strip is essential for Class III and IV restorations where light-curing from multiple angles is required. A professional matrix strip allows the clinician to pull the composite tightly against the tooth structure, minimizing the "oxygen-inhibited layer" and producing a highly polished surface. Our matrix strip options are selected for their flexibility and strength, helping dentists in Egypt achieve seamless transitions between natural tooth and resin.
Whether you are using composite, amalgam, or glass ionomer, choosing the right dental matrix materials is the first step toward a seamless finish.
How to Choose a Matrix Strip for Class IV Cases
- Material & Thickness: Select polyester (Mylar) strips with a thickness of 0.05mm. This provides the necessary rigidity to contour composite while remaining thin enough to glide through tight interproximal contacts.
- Chemical Resistance: Ensure the strip is solvent-resistant. This prevents the material from degrading or reacting when it comes into contact with the chemicals found in dental adhesives.
- Optimal Length: For large anterior reconstructions, use a strip at least 100 mm long. This extra length allows you to wrap the matrix around the tooth, providing the stability required to predictably build the palatal shelf and incisal edge.
