The purpose of this scoping review was to identify different methods employed for recording the maxillomandibular relationship (MMR) for computer-aided designed and manufactured (CAD-CAM) complete dentures (CDs).
This scoping review followed the PRISMA-ScR guidelines and was developed according to Arksey and O'Malley and The Joanna Briggs Institute protocol. The methods were registered on the Open Science Framework (< osf.io/rf4xm> ). The focus question was: "What are the different techniques for recording the maxillomandibular relationship in the digital workflow used in CECDs?" Two investigators searched 3 online databases [MEDLINE (PubMed), Scopus, and Science Direct] independently. The inclusion criteria were clinical studies and reviews that assessed techniques for recording MMR using digital workflow for manufacturing of CECDs. A descriptive analysis was performed considering the study design, manufacturing system, clinical steps, and tools for the determination of MMR, and the difficulty level of procedures.
4779 articles were identified in the electronic search and 10 studies were included for data analysis. The review identified 4 commercially available CAD-CAM denture systems and 3 innovative methods suitable for abbreviating the number of appointments (2 to 4 visits). The trial denture is inherent to the procedure for the Baltic System and 3 innovative techniques. Three techniques (2 innovative and WholeYouNexteeth) demonstrated lower difficulty levels for performing the clinical procedures, regardless of the professional skills.
The commercially available and innovative techniques for the recording of MMR may provide predictability of the treatment. The techniques are effective, however, rely on the learning curve and the patient's clinical condition.
Recording of the maxillomandibular relationship is paramount for the manufacturing and functionality of complete dentures. Clinicians should be aware of the different tools and techniques described for registering the jaw relationship.
本范围综述的目的是确定用于计算机辅助设计和制造（CAD-CAM）全口义齿（CD）记录颌位关系（MMR）的不同方法。
本范围综述遵循 PRISMA-ScR 指南，并根据 Arksey 和 O'Malley 以及 Joanna Briggs 研究所的方案制定。该方法已在开放科学框架（< osf.io/rf4xm>）上注册。关注的问题是：“在用于 CECD 的数字工作流程中，记录颌位关系的不同技术是什么？”两位研究人员独立搜索了 3 个在线数据库[MEDLINE（PubMed）、Scopus 和 Science Direct]。纳入标准是评估使用数字工作流程记录 MMR 技术以制造 CECD 的临床研究和综述。考虑研究设计、制造系统、确定 MMR 的临床步骤和工具以及程序的难度水平，对研究进行描述性分析。
电子搜索共确定了 4779 篇文章，10 项研究纳入数据分析。综述确定了 4 种市售的 CAD-CAM 义齿系统和 3 种适合缩短就诊次数（2 至 4 次）的创新方法。试验义齿是 Baltic 系统和 3 种创新技术固有程序的一部分。3 种技术（2 种创新技术和 WholeYouNexteeth）在进行临床操作时显示出较低的难度水平，无论专业技能如何。
记录颌位关系的市售和创新技术可提高治疗的可预测性。这些技术是有效的，但依赖于学习曲线和患者的临床状况。
记录颌位关系对于全口义齿的制造和功能至关重要。临床医生应该了解用于注册颌关系的不同工具和技术。
