Summary
This case report introduces a novel zirconia ceramic restoration for damaged anterior teeth. Computer-aided design and manufacturing (CAD/CAM) technology enables durable, single-unit post-core-crown restorations, enhancing treatment outcomes.
Area of Science:
- Restorative Dentistry
- Biomaterials Science
- Digital Dentistry
Background:
- Management of anterior teeth with reduced incisal clearance presents restorative challenges.
- Traditional post-core-crown systems can be prone to failure, especially under high functional loads.
- All-ceramic restorations offer esthetic advantages but require careful material selection for durability.
Observation:
- A case report details the use of a single-unit, all-ceramic zirconia restoration fabricated with Computer-aided designing and Computer-aided manufacturing (CAD/CAM) technology.
- This approach addresses reduced incisal clearance in damaged anterior teeth.
- The restoration unified the post, core, and crown into a single monolithic unit.
Findings:
- Reinforced zirconia ceramics provide durable and esthetic restorations suitable for high functional demands.
- The monobloc design of the single-unit restoration minimizes potential failure points.
- CAD/CAM technology facilitates the expeditious fabrication of these high-strength ceramic restorations.
Implications:
- This innovative CAD/CAM fabricated zirconia restoration offers a predictable and efficient treatment option for complex anterior tooth defects.
- The single-unit design enhances long-term prognosis and reduces clinical chair time.
- This approach represents a significant advancement in esthetic and functional restorative dentistry.

01:19Veneer
Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...

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.
