Summary
Maximum occlusal force increases with age and is higher in males than females. This force continues to develop into the 20s for males, while peaking around age 17 for females.
Area of Science:
- Orthodontics and Dental Biomechanics
- Craniofacial Biology
Background:
- Malocclusion affects dental alignment and facial structure.
- Understanding occlusal force is crucial for orthodontic treatment planning.
Purpose of the Study:
- To investigate the relationship between maximum occlusal force and maxillofacial skeletal patterns in individuals with malocclusion.
- To analyze age and gender-related differences in occlusal force and its correlation with skeletal features.
Main Methods:
- A cohort of 350 patients (150 males, 200 females) with malocclusion was studied.
- Maximum occlusal force was measured using a simplified occlusal force meter.
- Maxillofacial skeletal patterns were assessed via lateral cephalograms, with analysis stratified by age and gender.
Main Results:
- Maximum occlusal force demonstrated a positive correlation with age and was generally higher in males.
- In males, occlusal force increased through their 20s; in females, this increase plateaued around age 17.
- A negative correlation was observed between occlusal force and mandibular plane angle in certain age groups.
Conclusions:
- Occlusal force development is age-dependent and exhibits significant gender dimorphism.
- Males exhibit a longer period of occlusal force development compared to females.
- Maxillofacial skeletal patterns, specifically the mandibular plane angle, may influence occlusal force in malocclusion.

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...

01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:27Growth of Cartilage and Bone Tissue
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...
01:15Relation between Poisson's ratio, Modulus of Elasticity and Modulus of Rigidity
Deformation occurs in axial and transverse directions when an axial load is applied to a slender bar. This deformation impacts the cubic element within the bar, transforming it into either a rectangular parallelepiped or a rhombus, contingent on its orientation. This transformation process induces shearing strain. Axial loading elicits both shearing and normal strains. Applying an axial load instigates equal normal and shearing stresses on elements oriented at a 45° angle to the load axis.
01:14Muscles 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...
01:19Impact Loading
Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.
