概括
骨髓直线 (ML) 的宽度因性别和牙区域而异,特别是在M2区域,但与邻近的骨质质量无关. 在进行手术之前,准确的个体诊断至关重要.
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
- 牙科植入物学 牙科植入物学
背景情况:
- 骨髓直线 (ML) 是下中一个关键的解剖学地标.
- 了解ML的变化对于牙科手术至关重要,尤其是在没有牙的患者中.
- 以前的研究还没有完全阐明ML宽度与邻近骨质之间的关系.
研究的目的:
- 评估无牙下的骨髓直线 (ML) 宽度的变化.
- 为了分析相邻骨的微观架构.
- 为了确定ML宽度是否与周围骨质的质量相关.
主要方法:
- 分析了28个人类下的微计算机断层扫描 (μCT) 扫描.
- 在无牙前和部区域测量了ML宽度,皮层厚度 (CtTh) 和骨体积分数 (Avg.Ct.BV/TV,Avg.Tb.BV/TV).
- 进行了统计分析,以确定影响ML宽度的重要因素.
主要成果:
- ML宽度表现出显著的变异性,从前部增加到部,M2区域显示出最大的变异.
- 与女性相比,男性标本的ML宽度更大;M2区域显示了最宽的ML宽度.
- 没有发现ML宽度与皮层或椎骨质量之间有显著的关联.
结论:
- 骨髓质线的宽度是高度可变的,受性别和牙区域的影响,而不是骨质.
- M2区域显示了最大的ML宽度变化.
- 术前评估需要个性化评估,因为ML的变化和缺乏与骨质相关性.

The Hyoid Bone
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
Muscles of the Anterior Neck
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...
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 grinding food.
