Summary

This summary is machine-generated.

Alveolar bone maturation after orthodontic extrusion requires approximately two months. This study analyzed human biopsies to determine the optimal stabilization period for newly formed bone tissue, finding two months sufficient for maturation.

Area of Science:

Orthodontics
Oral and Maxillofacial Surgery
Regenerative Medicine

Background:

Alveolar bone undergoes remodeling during tooth movement.
The precise timeline for alveolar bone maturation post-orthodontic treatment is not well-defined.
Understanding bone modeling is crucial for successful orthodontic outcomes.

Purpose of the Study:

To investigate the bone modeling process of newly formed tissue after orthodontic extrusion.
To determine the maturation timing of neo-apposed bone in human mandibular molar sockets.

Main Methods:

Histomorphometric analysis of human biopsies from third mandibular molar sockets.
Extraction of teeth after varying stabilization periods following orthodontic extrusion.
Evaluation of histological parameters for bone quantity and quality.

Main Results:

Specimens primarily consisted of bone tissue.
Significant percentages of woven bone were observed at 1 and 1.5 months post-extrusion.
A notable decrease in woven bone was evident by the 2-month stabilization mark.

Conclusions:

A 2-month stabilization period appears sufficient for the maturation of neo-apposed bone after orthodontic extrusion.
Histomorphometric analysis provides insights into alveolar bone healing and remodeling timelines.
Findings contribute to optimizing orthodontic treatment protocols for bone regeneration.
