5 Reasons Why Your Business Needs Sectional Matrix Band？

Halo™ Sectional Matrix Bands

If you are looking for more details, kindly visit our website.

Halo matrix bands are made of ultra-thin 0,038 mm stainless steel that is anatomically contoured to the natural shape of the tooth. Halo matrix bands are anatomically shaped for ideal contacts and reduced time spent shaping and finishing a composite restoration.1 Available in Original and Firm, Original bands allow for greater adaptability, while Firm bands are ideal for tight interproximal spaces. Firm matrix bands are available with or without a special coating that is color coded according to size to assist you in selecting the correct band. Halo kits contain the complete Halo sectional matrix system, including the carousel dispenser. Read More

Choosing the best matrix system for the procedure and the patient can enhance clinical success

For more on this topic, go to www.dentaleconomics.com and search using the following key words: matrix bands, Class II composite restorations, Dr. Fred Margolis.

When restoring Class II adhesive restorations in children, teenagers, and adults, the goal is to provide 1) tight contacts, 2) good contours, and 3) proper anatomy. There are many types of matrices on the market, however, in restoring thousands of restorations in children and teenagers, I have found that segmental metal matrices provide for all three goals. The purpose of this article is to review several previously published articles and illustrate several examples of available matrices.

Case 2: Omni-matrix
The Omni-matrix™ (Ultradent Corp.) has several advantages over the classic Tofflemire™ retainer. The Omni-matrix has both pediatric and adult sizes and has the advantage of using metal or mylar strips. In this case, a teenager had her Class II restoration restored with the Omni-matrix. In a study by Gilmour, et al., the Omni-matrix was found to be a “suitable replacement for the non-disposable [Dentsply Ash] Siqveland matrix system.”1 See Figure 2.

Case 3: Sectional matrices with separation rings
According to Loomans, B.A., et al: “The use of sectional matrices combined with separation rings resulted in tighter proximal contacts compared to when circumferential systems were used.”2 I have found this to be true in both primary and permanent teeth when restoring Class II resin composite, compomer, resin-modified glass ionomers, and glass ionomer materials. Figure 3 illustrates the use of the segmental matrix system in primary Class II restorations in children.

Case 4: Segmental matrices with separation rings

I have lectured throughout the world and asked the audience which matrices give the best contacts they had ever experienced. In every case, their answer is segmental metal matrices. The segmental matrix, when used with a wedge and separation rings, gives tighter proximal contacts in permanent Class II restorations than any other matrix system I have worked with, as shown in Figure 4: Composi-Tight™ from Garrison Dental Solutions; and Figure 5: the V-Ring™ from TrioDent.

With a segmental matrix, the operator does not have to remove any wires, bands, or brackets, but can use the segmental matrix to provide the required contour and proximal contacts. (See Figure 6.)

Garrison Dental Solutions has newer 3-D rings that can be used for permanent teeth, however, due to their shape, I prefer the Gold or Gray rings for primary molars.

The Soft Face 3-D ring (orange) is more difficult for primary molars and around orthodontic appliances. In these cases, the Composi-Tight Gold or Gray thin-tine G-Rings are indicated.

Conclusion

Matrix bands with the use of wedges is an integral part of restorative dentistry. I have described various types of matrices that can be used in providing well-contoured restorations with good proximal contacts for Class II restorations in primary and permanent teeth. Dental practitioners must decide for themselves which system works best for them.

Based on the current scientific research, I have concluded that a segmental matrix provides tighter proximal contacts compared to circumferential matrix band systems.2
