目的：本病例系列的目的是介绍一个完整的数字化工作流程的生产整体种植体crows.Material和方法：6例患者进行了治疗与种植体支持冠树脂纳米陶瓷（RNC）。从口内光学扫描（IOS）开始，并遵循CAD/CAM过程，将整体式牙冠粘结到新型预制钛基台基底（A组）或软组织水平牙种植体上前磨牙或磨牙部位的CAD/CAM生成的个性化钛基台（B组）。经济学分析包括临床和实验室步骤。美学评价进行比较两个基台冠combination.Results：没有数字化构建RNC冠需要任何临床适应。总体平均工作时间计算显示A组（65.3 min）与B组（86.5 min）存在明显差异。美学分析表明一个更有利的结果为预制bonding bases.Conclusions：预制或个性化的基台上的整体RNC冠使用CAD/CAM技术在一个无模型的工作流程似乎提供了一个可行的和简化的治疗方法，单缺牙空间康复后区。然而，RNC作为全轮廓材料必须被认为是实验性的，并且需要进一步的大规模临床研究和长期随访观察。
Objectives: The aim of this case series was to introduce a complete digital workflow for the production of monolithic implant crowns.Material and methods: Six patients were treated with implant-supported crowns made of resin nano ceramic (RNC). Starting with an intraoral optical scan (IOS), and following a CAD/CAM process, the monolithic crowns were bonded either to a novel prefabricated titanium abutment base (group A) or to a CAD/CAM-generated individualized titanium abutment (group B) in premolar or molar sites on a soft tissue level dental implant. Economic analyses included clinical and laboratory steps. An esthetic evaluation was performed to compare the two abutment-crown combinations.Results: None of the digitally constructed RNC crowns required any clinical adaptation. Overall mean work time calculations revealed obvious differences for group A (65.3 min) compared with group B (86.5 min). Esthetic analysis demonstrated a more favorable outcome for the prefabricated bonding bases.Conclusions: Prefabricated or individualized abutments on monolithic RNC crowns using CAD/CAM technology in a model-free workflow seem to provide a feasible and streamlined treatment approach for single-edentulous space rehabilitation in the posterior region. However, RNC as full-contour material has to be considered experimental, and further large-scale clinical investigations with long-term follow-up observation are necessary.
