The Hyoid Bone01:12

The Hyoid Bone

5.5K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Self-Locking Screw01:16

Self-Locking Screw

2.6K
A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.

Tooth Anatomy

2.3K
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...

Spanning Openings in Brick Walls

588
In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...

Tongue

3.2K
The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

Oral Cavity01:11

Oral Cavity

3.3K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Area of Science:

  • Orthodontics and Pediatric Dentistry

Background:

  • The conventional lingual arch is a passive space maintainer designed to prevent mesial migration of permanent first molars in the mandibular arch.
  • Its primary limitation is its non-functional nature, offering only basic space maintenance.

Observation:

  • This study introduces a novel functional lingual arch incorporating a hinge-type lockable dentulous component.
  • This design integrates molar tubes, allowing for active intervention and enhanced functionality.

Findings:

  • The functional lingual arch demonstrates significant advantages over the conventional lingual arch in maintaining mandibular arch length.
  • The integrated hinge-type component and molar tubes provide greater control and adaptability.

Implications:

  • This innovative functional lingual arch represents a significant advancement in space management for pediatric dental patients.
  • It offers a more effective and versatile alternative for preventing molar movement and preserving arch integrity.
