Title: Influence of axiopulpal line angle and proximal retention on fracture strength of amalgam restorations. Author: Amorim A, de Lima Navarro MF, Mondelli J, Lopes ES. Journal: J Prosthet Dent; 1978 Aug; 40(2):169-73. PubMed ID: 278834. Abstract: Proximal retentive grooves significantly increase the strength of amalgam restorations in Class II cavities. There were no remarkable differences that could have clinical significance between sharp or rounded axiopulpal line angles and rounded or rounded and sloped pulpal walls. Chromium-cobalt dies are effective for tests of fracture strength of amalgam restorations.[Abstract] [Full Text] [Related] [New Search]
