Composite resin is the most cosmetic material used in restorative dentistry. Its functional and cosmetic features are enhanced by an appropriate finishing. A non finishing surface is very rough, allowing therefore plaque accumulation and pigments deposition deriving from feeding.
In this study the authors performed several finishing methods using diamond burs, abrasive disks and abrasive strips. All the samples were analyzed by means of SEM at 100x, 300x and 500x.
The results showed several differences among tested samples according to the material and the technique used. Satisfactory finishing is performed by the association of medium and fine sizes finishing burs (Intensiv 50/D4 and Intensiv 40/D4) and medium and fine abrasive disks (Sof Lex Pop On 3M 1981 M and F), or by medium and fine finishing abrasive burs and abrasive strips (Sof Lex 3M Coarse-Medium/Aluminum Oxide N. 1954-150 and Fine-Superfine N. 1956-120).
复合树脂是口腔修复学中使用的最具美观性的材料。通过适当的修整可以增强其功能和美观特性。未修整的表面非常粗糙,因此会导致牙菌斑堆积以及因进食产生的色素沉积。
在本研究中,作者使用金刚石车针、砂片和砂条进行了多种修整方法。所有样本均通过扫描电子显微镜在100倍、300倍和500倍下进行分析。
结果表明,根据所使用的材料和技术,测试样本之间存在若干差异。使用中号和小号修整车针(Intensiv 50/D4和Intensiv 40/D4)以及中号和小号砂片(Sof Lex Pop On 3M 1981 M和F),或者使用中号和小号修整砂针以及砂条(Sof Lex 3M粗-中号/氧化铝N. 1954-150和细-超细号N. 1956-120)可实现令人满意的修整效果。
