Hyperbaric oxygen therapy (HBOT) has beneficial effects for patients complaining of poor bone healing such as related to diabetes mellitus. However, it is known that changing pressure conditions might cause dental barotrauma in the oral cavity. The aim of this study was to evaluate implant mechanical stability under HBOT pressure. Thirty-five implants were placed in bone blocks divided into five groups as control, 1, 3, 5, 7 HBOT cycles. In one cycle, 2.4 bar 100% oxygen pressure was performed. Implants' stabilities were measured with resonance frequency analysis (RFA) and removal torque (RT) meter device. Data were analyzed using Shapiro Wilk, ANOVA, and Tukey HSD tests for RFA and RT values considering p < 0.05 as the statistical significance level. RFA and RT values were compared by Pearson correlation coefficiency. RFA values of 5 and 7 HBOT cycles were significantly lower than 1, 3 HBOT and control group (p < 0.001). There was no statistical difference between 5 and 7 HBOT cycles RFA values. HBOT pressure simulation slightly but statistically decreased the stability for the implants exposed to 5 and 7 HBOT cycles. Graphical abstract.
高压氧治疗（HBOT）对糖尿病等引起的骨愈合不良患者有有益的影响。然而，众所周知，改变压力条件可能会导致口腔中的牙科气压伤。本研究的目的是评估 HBOT 压力下植入物的机械稳定性。将 35 个植入物放置在骨块中，分为五个组：对照组、1、3、5、7 个 HBOT 循环。在一个循环中，以 2.4bar100%氧气压力进行。使用共振频率分析（RFA）和去除扭矩（RT）测量设备测量植入物的稳定性。对于 RFA 和 RT 值，使用 Shapiro Wilk、ANOVA 和 Tukey HSD 测试分析数据，考虑到 p < 0.05 为统计学意义水平。通过 Pearson 相关系数比较 RFA 和 RT 值。5 个和 7 个 HBOT 循环的 RFA 值明显低于 1 个、3 个 HBOT 和对照组（p < 0.001）。5 个和 7 个 HBOT 循环的 RFA 值之间没有统计学差异。高压氧压力模拟略微但统计学上降低了暴露于 5 个和 7 个 HBOT 循环的植入物的稳定性。
