概括

露西 (LJ) 和前部解编程器 (AD) 在健康成年人中有效地降低了定位中心关系 (CR) 的肌肉活动. 卢西亚Jig被评为最舒适的,而Leaf Gauge (LG) 是最不舒适的.

科学领域:

牙闭塞和生物力学
神经肌肉牙科神经肌肉牙科
临床假牙科临床假牙科

背景情况:

定位中心关系 (CR) 对于精确的牙科修复至关重要.
对于CR的确定存在不同的方法,可能会影响肌肉活动和患者舒适度.
在健康成年人中评估这些方法对于了解它们的临床适用性至关重要.

研究的目的:

为了比较肌肉活动和患者满意度,使用叶子测量仪 (LG),卢西亚Jig (LJ) 和前部Deprogrammer (AD) 来确定CR位置.
为了确定哪种方法产生最低的肌肉活动和最高的患者满意度.
评估CR定位方法对前肌和肌活动的影响.

主要方法:

30名健康成年人参加了一项随机交叉研究,每次有24小时的洗期.
表面电肌图 (Myowise) 测量了静止状态的肌肉活动,最大间位置 (MIP) 和CR位置之后.
用视觉模拟量表 (VAS) 和问卷来评估患者的满意度.

主要成果:

两种方法之间没有发现前肌活动的显著差异.
与叶子测量仪 (LG) 和露西亚Jig (LJ) 相比,前部脱编程仪 (AD) 的Masseter肌肉活动明显较低.
卢西亚Jig (LJ) 和前部Deprogrammer (AD) 显示CR肌肉活动与休息相比,明显低于MIP;LJ被评为最舒适,LG最低.

结论:

Muscles for Facial Expressions

Muscles for Facial Expressions

The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Muscles of the Anterior Neck

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...

Muscles that Move the Head

Muscles that Move the Head

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
