Summary
Cervical harnesses cause discomfort by compressing the jaw, chin, and cheeks. Bypassing the mandibular region may reduce pain and improve patient tolerance during treatment.
Area of Science:
- Orthodontics and dental biomechanics.
- Craniofacial pain management.
Background:
- Cervical harnesses are commonly used in orthodontic treatments.
- Current cervical harness designs can cause significant patient discomfort.
Purpose of the Study:
- To identify the limitations of current cervical harness designs.
- To propose an alternative approach for force application in cervical traction therapy.
Main Methods:
- Review of existing cervical harness designs and their biomechanical effects.
- Analysis of patient-reported discomfort associated with temporomandibular joint, chin, and cheek compression.
Main Results:
- Cervical harnesses exert pressure on the temporomandibular joints, chin, and cheeks.
- This compression leads to discomfort and pain, prompting patient resistance.
Conclusions:
- The mandibular region is a problematic area for force application with current cervical harnesses.
- Alternative methods that bypass the mandibular region could enhance patient comfort and treatment compliance.

01:19Muscles that Move the Head
7.6K
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...

1.2K
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

01:28Articulations of the Vertebral Column
3.4K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

01:14Cranial Bones: Superior and Posterior View
7.6K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
6.8K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
