Abstract

Purpose: CAD/CAM feldspathic ceramic (FC) materials remain used for their low cost and ease of chairside production. The purpose of this study was to describe preliminary clinical results, reporting the success and survival of FC dental crowns in a high-demand service using a simplified CAD/CAM technique.

Materials and methods: A calibrated dentist fabricated indirect restorations using the CEREC method and intraoral scanning (Cerec Omnicam, Cerec MCXL) for high-demand dental care. Forty crowns were seated adhesively and evaluated after 24 months using the newly validated UERJ criteria. Statistical analysis was performed with the McNemar test (p⟨.05).

Results: The survival clinical rate of FC CAD/CAM crowns after 24 months was 100%. However, 65% of indirect restorations presented reparable complications. No failure with loss of restoration was detected. Within the complications, most parts were in the proximal contact point, with statistically different significance in follow-up.

Conclusion: This study demonstrates that FC CAD/CAM crowns made using a simplified technique have a high clinical survival rate after 24 months, which is crucial for high-demand service. A more extended clinical evaluation period using the same criteria is necessary to draw further conclusions.

CAD/CAM长石冠在巴西海军牙科的存活：24个月的初步研究。

目的：CAD/CAM长石陶瓷（FC）材料因其低成本和易于椅边生产而继续使用。本研究的目的是描述初步的临床结果，报告使用简化的CAD/CAM技术在高需求服务中使用FC牙冠的成功和存活。材料和方法：经过校准的牙医使用CEREC方法和口内扫描（CEREC Omnicam, CEREC MCXL）制作间接修复体，用于高要求的牙科护理。在24个月后使用新验证的UERJ标准对40个冠进行粘接固定和评估。采用McNemar检验进行统计学分析（p⟨.05）。结果：FC CAD/CAM冠术后24个月临床成活率为100%。然而，65%的间接修复出现了可修复的并发症。没有检测到恢复丢失的故障。并发症中大部分发生在近端接触点，随访差异有统计学意义。结论：本研究表明，采用简化技术制作的FC CAD/CAM冠在24个月后具有较高的临床存活率，这对于高需求的服务至关重要。为了得出进一步的结论，有必要使用相同的标准进行更长的临床评估期。
