Abstract

Interocclusal records (IORs) created with bite registration materials (BRMs) accurately reflect the opposing teeth's physiological and anatomical associations in digital and traditional dentistry. This study assessed the linear dimensional accuracy of vinyl polysiloxane-based scannable and transparent BRMs over obligatory clinical time intervals (1, 24, 72, and 168 h/s). A total of 3 scannable [Flexitime Bite, Occlufast CAD, Virtual CADBite] and 3 transparent [Maxill Bite, Charmflex Bite, Defend ClearBite] VPS-based BRMs were divided into 28 subgroups by time interval: 1, 24, 72, and 168 h/s. Stereomicroscope measurements of 420 standardised disk-shaped specimens with three distinct linear distances between crossing vertical and horizontal lines were taken. Comparisons with the conventional BRM determined the scannable and transparent BRMs' accuracy, while comparisons with die dimensions yielded linear dimensional changes. Statistical analysis used median rank scores, interquartile range, and median. Using a one-way ANOVA rank and Dunn test, differences were assessed between and within groups at a probability '' value of 0.05 ( ≤ 0.05). Mean linear dimensions for CAD and transparent IOR materials were [-0.06 (-0.24%) to -0.15 (-0.6%)] and [-0.06 (0.24%) to -0.10 (0.40%)] millimetres, respectively. Virtual CADBite and Maxill Bite had the lowest linear disagreement after 1 h, but both showed significant variations at 7 days. Other commercial brands maintained their clinically acceptable linear accuracy (0.11). Flexitime Bite (CAD) was the sole material with a linear accuracy above the clinical threshold. IOR shrinkage reduced the linear dimensions in all materials. Until 7 days, all IOR materials except Flexitime bite (CAD) were clinically correct. Virtual CADBite and Maxill bite changed significantly during 1 h and 7 days.

摘要

使用咬合记录材料（BRM）制作的牙合间记录（IOR）在数字牙科和传统牙科中准确反映了对颌牙齿的生理和解剖关系。本研究评估了基于乙烯基聚硅氧烷的可扫描透明BRM在规定临床时间间隔（1、24、72和168小时/秒）内的线性尺寸精度。总共3种可扫描的[Flexitime Bite、Occlufast CAD、Virtual CADBite]和3种透明的[Maxill Bite、Charmflex Bite、Defend ClearBite]基于VPS的BRM按时间间隔分为28个子组：1、24、72和168小时/秒。对420个标准化圆盘形标本进行体视显微镜测量，标本上交叉的垂直线和水平线之间有三个不同的线性距离。与传统BRM的比较确定了可扫描和透明BRM的准确性，而与模型尺寸的比较得出线性尺寸变化。统计分析使用中位数秩分数、四分位间距和中位数。使用单向方差分析秩和邓恩检验，在概率值为0.05（≤0.05）时评估组间和组内差异。CAD和透明IOR材料的平均线性尺寸分别为[-0.06（-0.24%）至-0.15（-0.6%）]毫米和[-0.06（0.24%）至-0.10（0.40%）]毫米。Virtual CADBite和Maxill Bite在1小时后线性差异最小，但在7天时均显示出显著变化。其他商业品牌保持了其临床可接受的线性精度（0.11）。Flexitime Bite（CAD）是唯一一种线性精度高于临床阈值的材料。IOR收缩使所有材料的线性尺寸减小。直到7天，除Flexitime bite（CAD）外的所有IOR材料在临床上都是正确的。Virtual CADBite和Maxill bite在1小时和7天内发生了显著变化。
