Background: Metal-ceramic restorations are frequently made using laser sintering. The sintering process' layer thickness may have an impact on restoration adaptation. However, there is little information about its impact. Aim: The goal of this in vitro experiment was to compare the marginal adaptation of laser-sintered cobalt-chromium long span bridges and single crown frameworks made on different DMLS machines. Methods: Tooth preparation was carried out on a typhodont teeth set from 14-22 and for 16. The dies were scanned and the samples were designed using 3 Shape software. The samples were then laser sintered using 3 different DMLS machines. Sample size consisted of 6 samples for the long span framework and 6 samples for the single crown framework per machine. Marginal accuracy was evaluated at 6 different points (mesiobuccal, buccal, distobuccal, mesiopalatal, palatal and dist.. Read More»
