概括
传统的钻孔 (CD) 在植入骨切除过程中最大限度地减少热量. 骨密度缩小钻探 (OD) 对于较不密集的骨来说更好,有效地减少温度变化.
科学领域:
- 口腔和牙面部外科手术
- 生物材料工程 生物材料工程
- 牙科植入物学 牙科植入物学
背景情况:
- 在牙科植入物骨切除过程中最大限度地减少热损伤对于成功的骨整合至关重要.
- 不同的钻探方案和骨密度可以影响手术内温度.
研究的目的:
- 为了比较与骨密度钻井 (OD),常规钻井 (CD) 和单钻井 (SD) 协议相关的温度变化.
- 通过各种密度 (D1-D4) 和钻孔速度 (800rpm和1600rpm) 的人工骨块来评估这些效应.
主要方法:
- 一项体外研究涉及240个骨切除术,使用CD,SD和OD协议在人造骨上.
- 在灌条件下使用了12毫米长的钻孔,直径为3.3毫米,每分钟800和1600转.
- 红外热成像测量了每次骨切除术前后的温度变化 (ΔT).
主要成果:
- 在所有骨密度和骨速的CD和SD协议之间发现了显著的ΔT差异.
- CD显示较低的ΔT在1600rpm与800rpm;SD显示较高的ΔT在1600rpm.
- 在密度较低的骨头 (D1-D2) 中,CD产生了最低的温度增加,而在密度较低的骨头 (D4) 中,OD显示了较低的ΔT.
结论:
- 传统的钻井 (CD) 协议始终导致较低的温度变化,特别是在更密集的骨中.
- 骨密度提升钻探 (OD) 协议在减少不太密集的骨温度升高方面更有效.
- 钻孔方案和骨密度在骨切割准备过程中显著影响热变化.

01:14Temperature Measurement Sites
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
