The implantation of new teeth is the most effective, state-of-the-art method of tooth replacement. Patients can acquire new teeth that look like natural teeth and are almost as strong. However, even this method cannot be effective if the jawbones are not suitable to host the artificial roots. In this case, dental experts apply jaw bone augmentation procedures.

What is augmentation in jaw surgery?
Jaw augmentation is a surgical procedure that repairs or rebuilds the jawbone to improve its shape, size, or strength. It is usually used to correct dental implants.
Why is jaw augmentation necessary?
Yes, jawbone can regenerate, but the extent of regeneration depends on several factors. Bone is a living tissue that can repair and remodel itself over time, especially when stimulated. Here’s how it works: Jawbone growth typically slows down or stops after the age of 18, but certain factors can still influence bone changes throughout adulthood:
Bone loss from tooth loss: When teeth are missing for a long time, the jawbone shrinks due to lack of stimulation. Augmentation restores bone volume for implants.
Bone Grafting: Adding bone to strengthen the jawbone, often used in preparation for dental implants.
Ridge Augmentation: Expanding the width or height of the alveolar ridge (the part of the jaw that holds the teeth) to restore lost bone.
Can jawbones regenerate?
Natural bone regeneration: When a tooth is lost, the surrounding jawbone begins to shrink due to a lack of stimulation. However, in cases of minor injuries, the bone can heal on its own, especially if the patient is healthy and has a good diet. Does the jaw bone grow after the age of 18?
Natural growth & development: The lower jaw (mandible) may continue to grow slightly into the early 20s, especially in males. The upper jaw (maxilla) is usually fully developed by 18.
Bone Remodeling:
Even after growth stops, bone is constantly remodeling. This process allows the jawbone to adapt to changes in bite, tooth loss, or external forces like braces. However, without stimulation (like from teeth or implants), the jawbone can shrink over time.
Conditions that affect the Jawbone after 18: Missing teeth can lead to jawbone resorption (shrinking). Braces & orthodontics can influence minor changes in jaw position. Conditions like osteoporosis can affect bone density later in life.
So, while the jawbone doesn’t grow significantly after age 18, it remains a dynamic structure that can change and adapt based on external factors. Read about the
