Objective评估频率和数量的残留水泥后，附着的单块氧化锆冠标准和个性化ceramic abutments.Material和methodsTwenty患者（平均年龄58.9岁，在纳入研究; 30%男性）随机接受标准或个性化基台骨水平种植体。采用玻璃离子水门汀将氧化锆单冠固定在基牙上。制作带有咬合孔的牙冠，以便能够旋开基台-牙冠复合体。骨水泥固定后，立即移除上部结构，并以标准化方式对种植体-种植体软组织和基台-牙冠复合体进行拍照，以检测残留骨水泥。结果10个个体化基牙中有9个（90%）观察到残留骨水泥，而10个标准基牙中有4个（40%）观察到残留骨水泥（OR = 13.5，P = 0.049）。40个个体化基台表面中有27个（68%）受到影响，而40个标准基台表面中有12个（30%）受到影响。个体化基台表面观察到残留粘固剂的概率大约是标准基台表面的5倍（P= 0.005）。个体化基牙的龈沟表面覆盖率平均为1.17%（SD 2.85），标准基牙的龈沟表面覆盖率平均为3.78%（SD 7.40）。边缘的位置显着影响量的残留cement.ConclusionBoth个性化和标准的全瓷基台的结果在基台和龈沟表面上的龈下残留水泥少量。然而，个体化基台的使用并不能保证完全避免未被发现的骨水泥残留。使用基台肩可见的全瓷基台可避免未检测到的残留骨水泥。
ObjectiveTo assess the frequency and amount of residual cement after attachment of monolithic zirconia crowns to standard and individualized ceramic abutments.Material and methodsTwenty patients (mean age 58.9 years at inclusion in the study; 30% male) were randomized to receive either a standard or an individualized abutment on a bone‐level implant. Monolithic zirconia single crowns were attached to abutments by use of permanent glass–ionomer cement. Crowns were fabricated with an occlusal hole to enable unscrewing of the abutment–crown complex. Immediately after cementation, superstructures were removed and both the peri‐implant soft tissue and the abutment–crown complex were photographed in a standardized manner, to detect residual cement. Photographs were analyzed using Corel Photo Paint X7, and residual cement‐to‐total abutment and residual cement‐to‐peri‐implant soft tissue area ratios were calculated.ResultsResidual cement was observed for 9 of 10 (90%) individualized abutments, compared with 4 of 10 (40%) standard abutments (OR = 13.5,P= 0.049). Twenty‐seven of 40 (68%) individualized abutment surfaces were affected, compared with 12 of 40 (30%) standard abutment surfaces. The probability of observing residual cement was approximately five times higher for the surfaces of individualized abutments than for those of standard abutments (P= 0.005). The mean amount of sulcus surface covered by cement was 1.17% (SD 2.85) for the individualized abutments and 3.78% (SD 7.40) for the standard abutments. The position of the margin significantly affected the amount of residual cement.ConclusionBoth individualized and standard all‐ceramic abutments result in small amounts of subgingival residual cement on abutment and sulcus surfaces. However, use of individualized abutments does not guarantee complete avoidance of undetected cement rests. Undetected residual cement might be avoided by use of all‐ceramic abutments with visible abutment shoulders.
