Summary
Functional occlusion theory addresses dynamic occlusion, crucial for stable orthodontic treatment and temporomandibular joint (TMJ) health. It explains TMJ displacement
Area of Science:
- Dentistry and Orthodontics
- Biomechanical Engineering
- Dental Occlusion
Background:
- Current orthodontic treatment criteria primarily focus on static occlusion, neglecting dynamic occlusion.
- Inconsistencies between maximum intercuspation (MI) and centric relation (CR) can arise during orthodontic therapy.
- These occlusal discrepancies can compromise treatment stability and temporomandibular joint (TMJ) health.
Purpose of the Study:
- To introduce the principles and methodologies of functional occlusion theory.
- To highlight the importance of dynamic occlusion in orthodontic treatment planning and stability.
- To explain the relationship between TMJ position, occlusal harmony, and treatment outcomes.
Main Methods:
- Review and synthesis of existing literature on functional occlusion theory.
- Explanation of diagnostic methods for evaluating TMJ-occlusal relationships.
- Discussion of how functional occlusion theory addresses MI-CR discrepancies.
Main Results:
- Functional occlusion theory posits TMJ displacement as a cause of MI-CR disharmony and relapse.
- This theory provides a framework for assessing the interplay between MI, CR, and TMJ status.
- It offers insights into achieving stable and healthy occlusions through dynamic assessment.
Conclusions:
- Dynamic occlusion and TMJ health are critical for stable orthodontic outcomes.
- Functional occlusion theory offers valuable tools for orthodontists to evaluate and manage occlusal relationships.
- Adopting functional occlusion principles can improve treatment stability and prevent relapse.

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...

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

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.
