Tooth Anatomy

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...

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...

Veneer

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...

Area of Science:

Dentistry
Oral Surgery
Restorative Dentistry

Background:

Traumatic injuries to primary anterior teeth can lead to succedaneous tooth noneruption.
Missing anterior teeth cause significant psychological and social distress.
While various treatments exist, saving the natural tooth is not always possible.

Observation:

This paper details an immediate replacement of a maxillary central incisor.
The technique involves a fiber-composite resin splint using the extracted dilacerated tooth crown as a pontic.
Surgical extraction of the impacted permanent maxillary central incisor was performed.

Findings:

The described method allows for immediate tooth replacement.
Abutment teeth require minimal or no preparation, preserving their structure.
The technique is chairside, reversible, and cost-effective, avoiding laboratory expenses.

Implications:

This approach offers a viable interim solution for missing anterior teeth.
It is particularly useful for patients with incomplete growth, awaiting definitive prostheses.
The technique addresses both functional and aesthetic concerns in tooth avulsion cases.
