Guest guest Posted April 29, 2012 Report Share Posted April 29, 2012 Hi all, I just need help pleased I am so confused Acc to the following , 1.Does matrix prevent under,over contouring or overhanging??? It is important when rebuilding the proximal surfaces of any tooth to restore its contact rela-tionship with any adjacent tooth. Obviously the use of a matrix may compromise this objective as the thickness of the matrix is interposed between the fi lling material and the tooth. This problem is surmounted when using amalgam in two ways. First, having adapted the matrix to the tooth it is burnished outward to try to achieve a contact with the adjacent tooth. Second, a wooden or metal wedge should be inserted between the teeth if possible. This has a dual benefi t in that it helps to maintain adaptation of the band to the tooth surface cervically and it separates the teeth slightly. Once the wedge is in place the matrix can be loosened slightly to facilitate burnishing against the adjacent tooth.MC cabe 2.which metal is responsible for amalgam blackening,which one provides strength? Ref is appreciate Thanks Moka Sent from my iPad Quote Link to comment Share on other sites More sharing options...
