What is required to prevent a decline in bone mass after tooth extraction?

To prevent a decline in bone mass after tooth extraction, dynamic strain or load is essential. When a tooth is extracted, the surrounding bone that previously supported the tooth starts to lose its stimulus for maintenance and health. In orthodontic and dental contexts, the principle of Wolff's Law applies, which states that bone in a healthy person will adapt to the loads under which it is placed. Applying dynamic strain—through activities that put gentle stress on the bone—encourages bone remodeling and helps maintain bone density.

The presence of mechanical load prompts osteoblast activity (the cells responsible for bone formation) and inhibits osteoclast activity (the cells responsible for bone resorption). Thus, the right type of stress, such as what might occur during chewing or light functional loading after an extraction, is vital for preserving the volume and quality of the bone. This concept underscores the importance of maintaining some level of mechanical stimulation to prevent osteopenia (bone loss) post-extraction.

Options like absolute rest would lead to further bone resorption, as there would be no stimulus for maintenance. Intense physical activity may not be directed specifically enough to the area needing preservation and can even result in undue stress that may not benefit bone healing. Chemical stimulation, while it may
