概括

这项研究使用CBCT分析了下和精神通道 (MDC和MC) 的3D模式. 结果揭示了道与牙的接近以及手术期间的潜在风险,帮助牙科专业人员.

科学领域:

人体解剖学解剖学解剖学
口腔和牙面部外科手术
放射学放射学是一门学科.

背景情况:

下和脑道 (MDC和MC) 是下中的关键解剖结构.
了解它们与相邻的牙和脑孔的3D空间关系对于外科手术至关重要.

研究的目的:

分析下和精神通道 (MDC和MC) 的三维 (3D) 图案.
通过使用圆束计算断层扫描 (CBCT) 调查MDC和MC之间的关系以及牙和精神孔等突出外科创伤地标.

主要方法:

分析了354名患者 (18-67岁) 的CBCT扫描.
部第一个前到第二个部的区域在3D中被重建.
测量了MDC和MC参数相对于牙和精神.

主要成果:

下沟 (MDC) 呈现出接近邻近牙的水泥结 (CEJ) 的趋势,并且远离口腔皮层板从第一前到第二.
从前到第一的MDC距离到根顶 (RA) 是恒定的,但对于第二的MDC距离显著下降,10.8%的第二的MDC-RA距离小于2mm.
第三种类型的精神通道 (MC) 普遍存在 (66.0%) 和更长时间;第一种类型的MC可能与密切的MDC-RA和MDC-CEJ距离相关.

Imaging Studies III: Computed Tomography

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...

Tooth Anatomy

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
