Summary
Jaw relationships significantly influence foot biomechanics during gait. Temporomandibular joint disorders (TMD) alter plantar arch loading and surface distribution, highlighting the connection between jaw function and foot posture.
Area of Science:
- Biomechanics
- Orthodontics
- Podiatry
Background:
- The stomatognathic system (jaw, teeth, muscles) plays a crucial role in overall body posture.
- Temporomandibular joint disorders (TMD) are associated with various symptoms, potentially including altered biomechanical functions.
- The relationship between jaw occlusion and foot biomechanics, specifically the plantar arch, requires further investigation.
Purpose of the Study:
- To investigate the impact of different jaw relationships on plantar arch characteristics during gait.
- To compare plantar pressure and surface distribution in individuals with and without TMD under various occlusal conditions.
Main Methods:
- 168 subjects were divided into a control group and a TMD group.
- Baropodometric analysis evaluated plantar surface load, foot surface area, forefoot/rearfoot loading and surface, and body weight distribution.
- Measurements were taken under three dental occlusion conditions: mandibular rest position (REST), voluntary teeth clenching (VTC), and cotton rolls (CR).
Main Results:
- Significant differences in plantar parameters were observed between REST and CR, and VTC and CR conditions in the TMD group.
- The control group showed significant differences across all occlusal conditions for multiple plantar variables.
- The TMD group exhibited higher mean plantar arch pressure in VTC and increased forefoot/total foot surfaces in CR compared to the control group.
Conclusions:
- Jaw occlusion significantly affects plantar arch loading and surface distribution during gait.
- TMD is associated with altered foot biomechanics, suggesting a link between stomatognathic system health and posture.
- Monitoring postural changes during stomatognathic system treatment is recommended.

01:21Tooth 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.

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:20Spanning Openings in Brick Walls
In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...

01:09Functional Classification of Joints
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
