Summary
Orthodontic tooth movement successfully created stable new bone in patients with missing lateral incisors. This new bone formation and its stability were not influenced by canine position or inclination during treatment.
Area of Science:
- Orthodontics
- Periodontology
- Dental Implantology
Background:
- Orthodontic tooth movement is known to induce bone formation.
- Understanding bone regeneration during orthodontic treatment is crucial for long-term stability and potential implant placement.
Purpose of the Study:
- To quantify bone formation during maxillary canine distalization and retention in orthodontic patients.
- To evaluate the long-term stability of newly formed bone.
- To assess the influence of canine inclination and position on bone regeneration.
Main Methods:
- Retrospective analysis of 80 patients with missing lateral incisors treated with maxillary canine distalization.
- Measurements of alveolar ridge width and height at four time points: pre-treatment, post-treatment, 2 years post-retention, and 5 years post-retention.
- Assessment of canine inclination and distance from the central incisor.
Main Results:
- Alveolar ridge width decreased by 4% during treatment and 2% during retention.
- Alveolar ridge height decreased by an average of 0.26 mm during treatment and 0.38 mm during retention.
- No correlation found between initial canine inclination/distance and the amount or stability of new bone.
Conclusions:
- Bone created via orthodontic tooth movement demonstrates horizontal and vertical stability.
- Alveolar width changes were independent of the initial bone at the agenesis site.
- Favorable bone formation occurs when canines are distalized into the space of missing lateral incisors.

01:40Bone Remodeling
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.
01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:24Bone Formation by Endochondral Ossification
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
01:31Osteoclasts in Bone Remodeling
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 bone...

01:27Growth of Cartilage and Bone Tissue
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...
