    The study evaluated the long-term effects of alveolar ridge preservation (ARP) on soft tissue and bone changes after tooth extraction.

  • 2

    Sixty patients were randomly assigned to either an ARP group or a control group receiving conventional tooth extraction.

  • 3

    After 12 months, the ARP group exhibited significantly less bone resorption and better soft tissue aesthetics compared to the control group.

  • 4

    A strong negative correlation was found between aesthetic scores and bone resorption, highlighting the importance of bone support for soft tissue outcomes.

  • 5

    Immediate ARP using β-TCP and a collagen membrane significantly enhances aesthetic outcomes and provides a better foundation for future implant rehabilitation.
