Imaging Studies III: Computed Tomography

906
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

科学领域:

  • 生物材料工程 生物材料工程
  • 牙周内科医院 牙周内科医院 牙周内科医院
  • 牙科材料 牙科材料

背景情况:

  • 三维印制牙 (3DPT) 为自然牙 (NT) 的研究提供了一个有希望的替代方案.
  • 评估3DPT的内部解剖学和内牙科准备行为对于其验证至关重要.

研究的目的:

  • 描述和验证3DPT的支持材料移除协议 (SMRP).
  • 为了比较3DPT与NT的内部解剖学和内牙治疗准备行为.
  • 评估3DPT在比较内牙制备系统方面的充分性.

主要方法:

  • 为PolyJetTM 3DPT开发了一个支持材料移除协议 (SMRP).
  • 微计算机断层扫描 (microCT) 用于在制备前后扫描3DPT和NT.
  • 3DPT使用ProTaper Gold® (PTG) 和Endogal® (ENDG) 系统进行准备,并与NT进行比较.

主要成果:

  • 该SMRP有效地删除了支持材料 (SUP706BTM).
  • 在内部解剖学或准备行为 (p > 0.05) 中,在3DPT和NT之间没有发现显著差异.
  • 3DPT在使用PTG进行牙周内科准备时表现出与NT相似的行为.

结论:

  • 描述的SMRP对PolyJetTM 3DPT有效.
  • 3DPT足以复制NT内部解剖学和准备行为.
  • 3DPT适用于评估和比较内牙科准备系统.
