The effect of occlusal forces on restorations
The Journal of the Michigan Dental Association
|October 17, 2014
Summary
This review examines how occlusal forces, including normal chewing and abnormal bruxing, impact dental restorative materials. It explores material properties and bonding to ensure restoration durability under various forces.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
- Biomechanics
Background:
- Occlusal forces, encompassing normal masticatory loads and parafunctional forces like bruxism and clenching, significantly influence the longevity and integrity of dental restorations.
- Understanding the interaction between these forces and diverse restorative materials is crucial for clinical success.
Discussion:
- This review analyzes the physical properties of common restorative materials (e.g., composites, ceramics, alloys) and their susceptibility to occlusal loading.
- The efficacy of various bonding mechanisms in resisting occlusal forces and maintaining restoration-tooth interfaces is critically evaluated.
Key Insights:
- Different restorative materials exhibit varying resistance to wear, fracture, and debonding under occlusal stress.
- Bonding strategies play a pivotal role in mitigating the detrimental effects of occlusal forces on restoration durability.
Outlook:
- Further research should focus on developing novel materials and advanced bonding techniques with enhanced resistance to mechanical and biological challenges.
- Long-term clinical studies are needed to validate the performance of current and emerging restorative solutions under sustained occlusal forces.

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...

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...
