Bonded Amalgam Filling –⁠ Part I.Laboratory Evaluation after Seven, Eight and Nine Years

The laboratory evaluation of quality of peripheral occlusion of bonded amalgamfilling and its comparison with classical amalgam filling seven, eight and nine years since itwas made follows up the previous laboratory and clinical evaluation of bonded and classicalamalgam fillings. The results of evaluation after two, four, five and six years since these fillingswere made have already been published.In the beginning of this study (in 1994) the authors made 137 fillings altogether, 75 of thembonded and 62 control classical amalgam fillings of Ist and IInd class according to Black in thelateral segment of dentition in 21 patients. In an annual control examination, impressions ofthe study fillings were made and the replicas were used for the evaluation of quality of theperipheral occlusion of the fillings by the method of comparing with a series of standard models(Vivasacale) as well as the method of the index of marginal fractures (IMF).The results of a series of in vitro studies of various authors, who also evaluated the propertiesof bonded and classical amalgam filling, favor the bonded fillings. Statistical analyses of ourresults also proved slightly better results of the bonded fillings on both methods used. Thedetermined differences were not significant, though.
