Abstract

Objective: To evaluate the effect of body posture on occlusal contact.

Methods: A total of 30 healthy subjects were evaluated. T-Scan™ III was used to analyze the center of occlusal force (COF) and occlusal force distribution while subjects remained supine (SP), upright sitting with the head fixed (UP-HFI), upright sitting with the head free (UP-HFR), and natural standing (NS).

Results: The total trajectory length of COF was significantly longer in NS than in SP, UP-HFI, and UP-HFR. The COF area was significantly larger in UP-HFR than in SP and UP-HFI and also significantly larger in NS than in SP, UP-HFI, and UP-HFR. The anteroposterior occlusal force distribution (AOD) in NS shifted significantly forward, compared to SP, UP-HFI, and UP-HFR. AOD in UP-HFI and UP-HFR shifted significantly forward, compared to the SP position.

Conclusion: Changes in body posture affect the stability and anteroposterior balance of occlusal contacts.

身体姿势对咬合接触稳定性和平衡性的影响

目的：评估身体姿势对咬合接触的影响：评估身体姿势对咬合接触的影响：共对 30 名健康受试者进行了评估。采用 T-Scan™ III 分析受试者仰卧（SP）、头固定直立坐（UP-HFI）、头自由直立坐（UP-HFR）和自然站立（NS）时的咬合力中心（COF）和咬合力分布：结果：NS 的 COF 总轨迹长度明显长于 SP、UP-HFI 和 UP-HFR。UP-HFR的COF面积明显大于SP和UP-HFI，NS的COF面积也明显大于SP、UP-HFI和UP-HFR。与SP、UP-HFI和UP-HFR相比，NS的前胸咬合力分布（AOD）明显前移。与 SP 位置相比，UP-HFI 和 UP-HFR 的咬合力分布明显前移：结论：身体姿势的变化会影响咬合接触的稳定性和前后平衡。

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
