概括
侧脊增强 (LRA) 对大多数患者成功增加了骨,特别是在下. 圆束计算机断层扫描 (CBCT) 图像证实了显著的骨再生,有助于牙植入物放置.
科学领域:
- 口腔和牙面部外科手术
- 牙科植入物学 牙科植入物学
- 再生医学是一种再生医学.
背景情况:
- 侧脊增强 (LRA) 是一个关键的程序,在植入牙之前增强骨体积.
- 圆束计算断层扫描 (CBCT) 提供精确的术前和术后成像,用于定量骨评估.
- 评估骨再生效率对于成功的植入物结果至关重要.
研究的目的:
- 通过使用CBCT成像来定量评估侧边增强 (LRA) 后的骨再生.
- 为了比较手术前和手术后的骨尺寸 (宽度,高度,体积) 在无牙的脊梁中.
- 为了确定影响LRA后骨增长的因素.
主要方法:
- 对30名接受LRA治疗的成年患者进行了回顾性分析,并进行了手术前和后的CBCT扫描.
- 线性测量 (宽度,高度) 和体积分析骨增长在牙的地方.
- 检查员内部的高可靠性 (类内部系数>0.974) 证实了测量的准确性.
主要成果:
- 在线性 (1.5-2.5毫米) 和体积 (250-750毫米3) 测量中观察到显著的平均骨增长.
- 手术前的骨体积和下位置是骨增长的最强预测因素.

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...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
