Assess the thermal effect of prosthodontic treatment on the cranio-cervico-mandibular complex using infrared thermography.
The treatment group was composed of adults of both sexes who underwent a prosthodontic treatment in which at least posterior occlusal contacts were added and/or the vertical dimension of occlusion was reestablished. The control group (CG) was constituted of adult subjects of both sexes, with no more than a single missing posterior tooth, excluding third molars. Thermograms were taken of the treatment group with a Flir i7 IR camera both before oral rehabilitation (TGB; = 33) and two months after treatment was concluded (TGA; = 19). CG ( = 33) had only one occasion for data acquisition.
Statistically significant differences were found when the thermal difference (ΔT) and the health status of the orbicularis oris muscle were compared between the TGB and the TGA groups ( = 0.020 and = 0.003, respectively). By comparing the health status of the masseter muscle between the CG and TGB, statistically significant differences were also observed ( = 0.030).
A prosthodontic treatment appears to have a minimum or null effect on the ΔT and/or on the health status of the TMJ and the temporal muscle. In contrast, orbicularis oris muscles exhibited significant thermal variations.
使用红外热成像技术评估口腔修复治疗对颅颈颌复合体的热效应。
治疗组由接受口腔修复治疗的成年男女组成，这些治疗至少增加了后牙的咬合接触，或重新建立了咬合垂直距离。对照组（CG）由成年男女组成，仅有一颗后牙缺失，不包括第三磨牙。用 Flir i7 IR 相机对治疗组（TGB；n = 33）在口腔修复治疗前（TGB；n = 33）和治疗结束后两个月（TGA；n = 19）进行热成像。CG 仅在一次情况下采集数据。
当比较 TGB 和 TGA 组之间的热差异（ΔT）和口轮匝肌健康状况时，发现存在统计学显著差异（= 0.020 和= 0.003）。通过比较 CG 和 TGB 之间咀嚼肌的健康状况，也观察到统计学显著差异（= 0.030）。
口腔修复治疗似乎对 TMJ 和颞肌的 ΔT 和/或健康状况的影响最小或为零。相比之下，口轮匝肌表现出显著的热变化。
