After tooth extraction, the alveolar bone, which supports the teeth, undergoes a natural resorption process. This bone loss can be significant, especially in the first few months post-extraction, leading to a reduction in both bone height and width. This resorption can compromise the structural foundation required for future dental restorations, such as implants, bridges, or dentures.
Socket preservation technique has been proposed since years as a technique to preserve alveolar bone following extraction and has proved excellent clinical efficacy over years.
Several materials have been proposed for alveolar ridge preservation, such as autografts, allografts, xenografts, and alloplasts, each with its own set of advantages and limitations. However, these materials may have limitations, including potential immunogenic responses and variable integration.
Thus, there is always a need to explore and validate new materials to mitigate these issues. This study aims to tests one of these new materials named chitosan gel to investigate whether the application of this chitosan gel following posterior mandibular tooth extraction would better preserve alveolar ridge dimensions and improve bone quality compared to normal socket healing or not ?.
