The electronic pantograph (Pantronic) records mandibular movements and computes the articulator settings. The Pantronic pantograph does not determine the intercondylar distance but approximates it from the interfacial width at the condyles. An average distance of 12.5 mm is subtracted from each side to determine the intercondylar distance. This study recorded 45 patients' articulator intercondylar distances that had been set from a mechanical pantograph and they were compared with the Pantronic's approximation. The difference between the interfacial width and the actual intercondylar distance was 15.1 mm on the right side and 14.9 mm on the left side. A numerical value of 15.0 mm was statistically superior to the Pantronic's 12.5 mm in estimating the average distance between the intercondylar distance and the surface of the skin at the condyle. No statistically significant difference was found between the differences of interfacial width and intercondylar distance values for men and women (p greater than 0.05). The mean intercondylar distance was 56.5 mm on the right side and 56.7 mm on the left side. A statistically significant difference was found between the mean intercondylar distances of men and women (p less than 0.05).
电子面弓（Pantronic）记录下颌运动并计算咬合架设置。Pantronic面弓并不确定髁间距离，而是根据髁突处的界面宽度来估算。从每一侧减去12.5mm的平均距离以确定髁间距离。本研究记录了45例通过机械面弓设置的咬合架髁间距离，并将其与Pantronic面弓的估算值进行比较。右侧界面宽度与实际髁间距离的差值为15.1mm，左侧为14.9mm。在估算髁间距离与髁突处皮肤表面之间的平均距离时，15.0mm的数值在统计学上优于Pantronic面弓的12.5mm。男性和女性在界面宽度与髁间距离值的差异上未发现统计学显著差异（p大于0.05）。右侧髁间平均距离为56.5mm，左侧为56.7mm。男性和女性的髁间平均距离之间存在统计学显著差异（p小于0.05）。
