简要总结
The proximal contacts protect the stomatognathic system as well as the periodontium against damage by providing harmony and balance. Failure to reproduce contact area will cause subsequent periodontal diseases and tooth movements. It continues to represent a great obstacle for dental practitioners to restore optimum proximal contours and contact points with resin composites restorations.The circumferential matrix systems showed significant looser proximal contacts for Class II cavities, which might be explained by the thickness of the matrix when placing a two-surface restoration . It was shown that when placing Class II resin composite restorations, the use of sectional matrix systems and separation rings resulted in tighter proximal contacts than when traditional circumferential matrix systems, without separation rings, are applied.
Palodent V3 introkit sectional matrix system is introduced which is integrated sectional matrix system from DENTSPLY that delivers easy, predictable and accurate contacts using innovative component technology.The Garrison Slick band architecture features a moderate, average curve, a great compromise between one with a more pronounced proximal convexity, such as the Triodent /Palodent Sectional matrix systems and one without any convexity at all. This allows fitment in narrow proximal areas where root proximity is more of an issue and allows placement without the need to enameloplasty the enamel of the adjacent tooth.To the best of our knowledge no study has compared contacts and contour of permanant mandibular molars Using dentsply Palodent V3 introkit sectional matrix system, Garrison Compositight 3D Fusion Sectional Matrix System and Tofflemire matrix systems for restoring class II composite restorations .Therfore the aim of this study is to evaluate and compare contacts and contour of permanant mandibular molars Using dentsply Palodent V3 introkit sectional matrix system, Garrison Compositight 3D Fusion Sectional Matrix System and Tofflemire matrix systems for restoring class II composite restorations.
