Abstract

Purpose

This study evaluated the influence of different agents such as blood, artificial saliva, and normal saline on preload force of dental implants with bio-high-performance poly-ether-ether-ketone (Bio-HPP) abutments to determine its effect on screw loosening.

Methods

Forty (N = 40) Grade 5 titanium dental implant analog (GM Implant Analog; Neodent, Straumann) with Bio-HPP poly ether-ether ketone (PEEK) abutment and titanium screw was used in the study. The samples were embedded in acrylic split mold. In the control Group C, no agent was added. In the other three groups, blood (B), normal saline (N) and saliva (S) was added in the access cavity of the samples. A sequential torque of 15 Ncm, 20 Ncm, 25 Ncm, 30 Ncm up to 35 Ncm was applied with a digital torque meter (Eclatorq, model: SD-05bn, range:2.5–50 Ncm, torque accuracy: ± 2%cw). Samples were subjected to thermomechanical cyclic loading at 5–55⁰ Celsius for 1000 cycles (Chewing simulator, CS 4.4) to simulate six months of clinical service. Preload was measured as reverse torque value (RTV). Raw data in the form of mean ± standard deviation was documented and subjected to statistical analysis. A one-way ANOVA was performed to contrast the groups. Tukey HSD test was used to determine the multiple comparison assessment (P < 0. 05).

Results

A mean reverse torque value of 35 Ncm ±0.00 was observed in both control and in groups exposed to normal saline (P >.05). Measurements of 33.4 Ncm ±2.51 and 34.8 Ncm ±0.40 were found when exposed to blood and artificial saliva in order (P < .05). When compared with control, exposure to blood showed significant variation in preload (P = .03).

Conclusion

A significant reduction in reverse torque force was observed when titanium implants and Bio-HPP abutments were exposed to blood, suggesting a potential risk of screw loosening (P < .05). In contrast, minimal decrease and no significant change in preload were noted with exposure to saliva and normal saline (P > .05).

不同药剂对使用生物高性能聚醚醚酮基台的牙科种植体预紧力的影响

目的本研究评估了血液、人工唾液和生理盐水等不同介质对带有生物高性能聚醚醚酮（Bio-HPP）基台的牙科种植体预紧力的影响，以确定其对螺钉松动的影响。方法本研究使用了 40 个（N = 40）带有 Bio-HPP 聚醚醚酮（PEEK）基台和钛螺钉的 5 级钛牙科种植体模拟体（GM Implant Analog；Neodent，Straumann）。样品嵌入丙烯酸裂模中。对照组 C 未添加任何药剂。在其他三组中，样品的取穴中添加了血液（B）、生理盐水（N）和唾液（S）。用数字扭矩仪（Eclatorq，型号：SD-05bn，范围：2.5-50 Ncm，扭矩精度：± 2%cw）依次施加 15 Ncm、20 Ncm、25 Ncm、30 Ncm 至 35 Ncm 的扭矩。样品在 5-550 摄氏度的温度下进行 1000 次热力学循环加载（咀嚼模拟器，CS 4.4），以模拟六个月的临床使用。预负荷以反向扭矩值（RTV）进行测量。原始数据以平均值±标准偏差的形式记录并进行统计分析。对各组进行单因素方差分析。结果对照组和接触生理盐水组的平均反向扭矩值为 35 Ncm ±0.00 (P>.05)。在接触血液和人工唾液时，测量值依次为 33.4 Ncm ±2.51 和 34.8 Ncm ±0.40（P <.05）。结论当钛种植体和 Bio-HPP 基台暴露于血液中时，反向扭矩力显著降低，表明存在潜在的螺钉松动风险（P < .05）。相比之下，暴露在唾液和生理盐水中时，预紧力下降很小，没有明显变化（P >.05）。

期刊介绍： Journal of Oral Biology and Craniofacial Research (JOBCR)is the official journal of the Craniofacial Research Foundation (CRF). The journal aims to provide a common platform for both clinical and translational research and to promote interdisciplinary sciences in craniofacial region. JOBCR publishes content that includes diseases, injuries and defects in the head, neck, face, jaws and the hard and soft tissues of the mouth and jaws and face region; diagnosis and medical management of diseases specific to the orofacial tissues and of oral manifestations of systemic diseases; studies on identifying populations at risk of oral disease or in need of specific care, and comparing regional, environmental, social, and access similarities and differences in dental care between populations; diseases of the mouth and related structures like salivary glands, temporomandibular joints, facial muscles and perioral skin; biomedical engineering, tissue engineering and stem cells. The journal publishes reviews, commentaries, peer-reviewed original research articles, short communication, and case reports.
