Bone Disorders01:29

Bone Disorders

5.9K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone Remodeling01:40

Bone Remodeling

40.9K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

7.0K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.6K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Tooth Anatomy01:21

Tooth Anatomy

2.6K
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...

Summary
This summary is machine-generated.

Reduced bone density can accelerate orthodontic tooth movement (OTM) but may increase risks like external apical root resorption (EARR). Understanding these factors is crucial for successful accelerated orthodontic treatment.

Area of Science:

  • Orthodontics
  • Dental Physiology
  • Bone Biology

Background:

  • Accelerated orthodontic treatment aims for faster results with stability.
  • Bone density is a key factor influencing the speed of orthodontic tooth movement (OTM).
  • Patient-specific factors like genetics and health status impact bone density and metabolism.

Purpose of the Study:

  • To explore the relationship between bone density and accelerated orthodontic tooth movement (OTM).
  • To identify how systemic and local bone density variations affect OTM velocity.
  • To assess the potential risks associated with altered bone density during orthodontic treatment, including external apical root resorption (EARR).

Main Methods:

  • Review of literature on bone density and orthodontic tooth movement.
  • Analysis of factors influencing systemic and local bone metabolism.
  • Examination of the correlation between bone density changes and OTM outcomes.

Main Results:

  • Decreased bone density significantly enhances the velocity of orthodontic tooth movement (OTM).
  • Systemic factors (genetics, disease) and local bone conditions influence bone density.
  • Altered bone density can increase the risk of adverse effects, such as external apical root resorption (EARR).

Conclusions:

  • Orthodontists must consider bone density variations for predictable accelerated orthodontic treatment.
  • Reduced bone density speeds up OTM but elevates the risk of external apical root resorption (EARR).
  • A comprehensive understanding of patient health and bone status is vital for managing accelerated orthodontics.
