摘要

(1) 背景:外径车针有两种不同的使用模式:(i) CW 和 (ii) CCW。本研究的目的是通过四向交互作用评估种植体截骨制备过程中的ΔT。(2)方法:在人体尸体胫骨上制备了 360 个深度为 12 毫米的截骨。ΔT值的计算方法与我们小组之前进行的两项研究中使用的方法类似。评估了四个不同变量对 ΔT 的影响。(3) 结果:在 CCW 模式中观察到了四向交互作用,使得 1000 RPM 在两种模式中的影响最小。然而,在 CCW 模式下,与 CW 模式相比,在 23 次截骨后使用 3.0 和 4.0 车针,ΔT 有显著的统计学增长,且有明显的颤振。在 CCW 模式下,随着车针直径在 800 和 1200 RPM 下的增加,ΔT 也明显增加。 (4) 结论:钻头直径、CCW 模式、800 和 1200 RPM 以及车针使用次数(超过 23 次)的协同效应对 ΔT 有显著影响,ΔT 超过 47 °C。在两种模式下,1000 转/分的影响最小。CCW 模式下的 3.0 和 4.0 车针使温度急剧升高,并产生明显的颤振。

Temperature Changes (ΔT) in Correlation with Number of Implant Osteotomy Preparations in Human Cadaver Tibiae, Comparing Osseodensification (OD) Burs in Clockwise (CW) versus Counterclockwise (CCW) Mode.

(1) Background: OD burs are used in two different modes: (i) CW and (ii) CCW. The purpose of the study was to evaluate the ΔT during the preparation of implant osteotomies in a four-way interaction. (2) Methods: Three hundred and sixty osteotomies were prepared at 12 mm depth in human cadaver tibiae. The ΔT values were calculated similarly to the method used in two previous studies carried out by our group. Four different variables were evaluated for their effect on ΔT. (3) Results: A four-way interaction was observed in the CCW mode, allowing for 1000 RPM to have the least effect in both modes. However, in the CCW mode the use of 3.0 and 4.0 burs after 23 osteotomies showed a statistically significant increase in ΔT, and significant chatter, compared to the CW mode. In the CCW mode, the ΔT was increased significantly as the diameter of the burs increased in 800 and 1200 RPM. (4) Conclusions: The synergistic effect of drills' diameter, CCW mode, 800 and 1200 RPM, and bur usage (over 23 times) had a significant effect on ΔT, which exceeded 47 °C. One thousand (1000) RPM had the least effect in both modes. The 3.0 and 4.0 burs in the CCW mode drastically increased the temperature and produced significant chatter.

期刊介绍: Journal of Functional Biomaterials (JFB, ISSN 2079-4983) is an international and interdisciplinary scientific journal that publishes regular research papers (articles), reviews and short communications about applications of materials for biomedical use. JFB covers subjects from chemistry, pharmacy, biology, physics over to engineering. The journal focuses on the preparation, performance and use of functional biomaterials in biomedical devices and their behaviour in physiological environments. Our aim is to encourage scientists to publish their results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Several topical special issues will be published. Scope: adhesion, adsorption, biocompatibility, biohybrid materials, bio-inert materials, biomaterials, biomedical devices, biomimetic materials, bone repair, cardiovascular devices, ceramics, composite materials, dental implants, dental materials, drug delivery systems, functional biopolymers, glasses, hyper branched polymers, molecularly imprinted polymers (MIPs), nanomedicine, nanoparticles, nanotechnology, natural materials, self-assembly smart materials, stimuli responsive materials, surface modification, tissue devices, tissue engineering, tissue-derived materials, urological devices.
