摘要
目的:探讨不同的髁突中心关系(CR)记录中髁突位置的变化情况。材料和方法:对81名口腔健康、牙齿发育完整的受试者进行6种不同类型的CR记录,由4名有执照的临床医生反复记录CR时的髁突位置。上颌模型在单独脸弓转移后安装在关节器中,下颌骨模型安装在哥特式拱门顶端的中心支承点(CBP)注册。计算了六种方法三次配准的均值,并进行了比较计算。结果:髁突位置与CBP与其他CR记录之间的中位空间距离为0.73±0.24 mm (0 ~ 3.19 mm)。不同CR记录髁突位置间的空间中位数为0.48 ~ 0.79 mm。统计上,几乎所有类型的注册位置都略有不同。结论:不同的CR记录再现的下颌骨位置略有不同,特别是CBP登记,而登记之间的重现性和SDs相似。在精度和时间要求方面,使用双手操作的未精制蜡晶片配准已被证明特别成功,就髁位置而言,CBP配准也是如此。
Is There "A Best" Centric Relation Record? Centric Relation Records, Condyle Positions, and Their Practical Significance.
Purpose: To investigate if and how the positions of condyles in centric relation (CR) varied from each other using different CR records.
Materials and methods: Condylar positions in CR were repeatedly recorded by four licensed clinicians in 81 stomatognathically healthy, fully dentate subjects with six different types of CR records. The maxillary casts were mounted in articulators after individual facebow transfer, and the mandibular casts were mounted with a central bearing point (CBP) registration on the tip of the Gothic arch. Mean values from three registrations of the centric condylar positions with each of the six methods were calculated, and comparative calculations were made.
Results: The median spatial distances of the condylar positions between the CBP and all other CR records was 0.73 ± 0.24 mm (0 to 3.19 mm). The median spatial values between the condylar positions of the different CR records ranged from 0.48 to 0.79 mm. Statistically, the positions of almost all types of registration were slightly different from each other.
Conclusion: Different CR records reproduce slightly different positions of the mandible, which is especially true for CBP registration, whereas reproducibilities and SDs between registrations are similar. Unrefined wax-wafer registrations using bimanual manipulation have proven particularly successful with regard to precision and time requirements, as has CBP registration with regard to condylar position.

Prosthodontics demands a clinical research emphasis on patient- and dentist-mediated concerns in the management of oral rehabilitation needs. It is about making and implementing the best clinical decisions to enhance patients'' quality of life via applied biologic architecture - a role that far exceeds that of traditional prosthetic dentistry, with its emphasis on materials and techniques. The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today''s prosthodontist, clinician, and educator alike. The editorial board is composed of a distinguished team of leading international scholars.
