Area of Science:

  • Restorative Dentistry
  • Dental Materials Science

Background:

  • Accurate Class II amalgam restoration requires precise matrix and wedge placement.
  • Improper technique can lead to compromised contours, contacts, and material integrity.
  • Deep sub-gingival gingival cavosurface margins present unique challenges in achieving optimal restoration.

Purpose of the Study:

  • To present an effective technique for adapting matrix bands in Class II amalgam restorations.
  • To address challenges associated with deep sub-gingival gingival cavosurface margins.
  • To improve the success rate of complex amalgam restorations through proper matrix adaptation.

Main Methods:

  • Description of a technique utilizing a combination of matrix bands.
  • Focus on adaptation strategies for deep sub-gingival margins.
