Tooth Anatomy01:21

Tooth 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.
Veneer01:19

Veneer

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...
Teeth01:15

Teeth

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...
Mortar Properties01:17

Mortar Properties

Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to the...

Summary
This summary is machine-generated.

All-ceramic restorations offer aesthetic and durable options for posterior teeth, though their long-term success rates are slightly lower than anterior restorations. Preparation and occlusal forms may need adaptation for optimal ceramic restoration performance.

Area of Science:

  • Dental Materials Science
  • Restorative Dentistry
  • Biomaterials Engineering

Background:

  • All-ceramic restorations are gaining popularity due to patient aesthetic demands and improved fabrication.
  • Longevity of ceramic restorations is comparable to traditional plastic restorations in posterior teeth.
  • Advancements in cementation and bonding have enhanced restoration longevity.

Purpose of the Study:

  • To review evidence supporting all-ceramic restorations, especially for posterior teeth.
  • To propose modifications in tooth preparation for dental ceramics.
  • To suggest an alternative occlusal form based on evolutionary principles.

Main Methods:

  • Literature review of existing evidence on all-ceramic restorations.
  • Analysis of factors influencing the longevity of posterior ceramic restorations.
  • Conceptual proposal for altered preparation and occlusal morphology.

Main Results:

  • Posterior all-ceramic restorations show a slightly lower success rate than anterior ones.
  • Success rates for posterior ceramic restorations tend to decrease over time.
  • Current preparation and occlusal forms may not be optimal for dental ceramics.

Conclusions:

  • All-ceramic restorations are a viable option for posterior teeth, but long-term success requires careful consideration.
  • Tooth preparation design may need to be adapted to the properties of ceramic materials.
  • A novel approach to occlusal morphology, considering natural tooth evolution, is proposed for better functional outcomes.
