Crown and bridge disassembly--when, why and how.
Summary
Dental crown and bridge removal can be destructive. This paper classifies non-destructive removal systems, explaining their function and clinical application for easier restorative procedures.
Area of Science:
- Restorative Dentistry
- Prosthodontics
- Dental Materials Science
Background:
- Dental crowns and bridges have limited longevity and are prone to failure.
- Current methods for removing failed restorations are often destructive, complicating subsequent treatments.
- Clinical situations exist where conservative removal is preferable for restorative or endodontic procedures.
Purpose of the Study:
- To classify existing crown and bridge removal systems.
- To describe the mechanisms of action for various removal systems.
- To provide guidance on the appropriate clinical application of these systems.
Main Methods:
- Literature review and classification of crown and bridge removal techniques.
- Description of the principles behind different non-destructive removal systems.
- Analysis of clinical scenarios favoring conservative disassembly.
Main Results:
- A classification system for crown and bridge removal methods is proposed.
- Detailed explanations of how various systems facilitate conservative removal are provided.
- Indications and contraindications for using specific removal systems are discussed.
Conclusions:
- Conservative crown and bridge removal systems offer a valuable alternative to destructive methods.
- Understanding these systems aids practitioners in managing failed restorations more effectively.
- Appropriate selection and use of removal systems can preserve tooth structure and facilitate further dental treatment.

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.

01:15Teeth
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...

01:08Brick Cutting Techniques
Brick-cutting techniques involve various tools and methods to shape bricks for construction. A mason's hammer with a chisel-pointed end is used for basic shaping through sharp, precise strikes. For more complex shapes requiring higher precision, a power saw with a water-cooled diamond blade is used.
Cut bricks are categorized by size. Bricks cut to half their original length are called half-bats, while those cut to three-fourths their length are known as three-fourth bats.
