摘要

计算机辅助制造(CAM)技术允许使用不同的制造技术。这项体外研究旨在评估使用传统椅旁方法、铣削法和三维打印法制作的临时修复体的边缘密合度。研究人员制作了 15 个三元素临时修复体标本,并将其分为三组:使用传统椅旁方法获得的非数字化标本(GC)、铣制标本(GM)和三维打印标本(GP)。在两种条件下使用扫描电子显微镜(SEM)评估边缘密合度:一种是仅拧紧中心螺丝,另一种是拧紧所有三个螺丝。水平拟合值分为过大、相等和过小,并进行定性分析。统计分析采用 Tukey-Kramer 检验(α=0.05)。在垂直评估中,三维打印修复体的不密合度高于通过铣削和传统椅旁方法获得的修复体(P<0.05)。

Influence of fabrication method on the marginal fit of temporary restorations.

Computer-aided manufacturing (CAM) technology allows the use of different manufacturing techniques. This in vitro study aimed to evaluate the marginal fit of temporary restorations manufactured using conventional chairside methods, milling, and three-dimensional printing. Fifteen 3-element temporary restorations specimens were produced and categorized into three groups: non-digital, obtained using the conventional chairside method (GC); milled (GM); and three-dimensionally printed (GP). Marginal fit was assessed using scanning electron microscopy (SEM) performed under two conditions: one with only the central screw tightened, and the other with all three screws tightened. Horizontal misfit values were categorized as over-, equal-, and under-extended and qualitatively analyzed. Statistical analysis was performed using the Tukey-Kramer test (α=0.05). In the vertical assessment, three-dimensionally printed restorations demonstrated greater misfit than restorations obtained by milling and the conventional chairside method (P<0.05). In the horizontal assessment, the misfit in the GP group was significantly higher than that in the GM and GC groups. Restorations obtained using the conventional chairside method and milled provisional restorations showed more favorable results than three-dimensionally printed restorations.
