简要总结

In this experiment, after non-traumatic tooth extraction, the blank group underwent natural healing, and the Bio-Oss Collagen underwent alveolar ridge preservation using Bio-Oss Collagen and the Sticky Bone group using Sticky Bone, to verify the application of Bio-Oss Collagen and Sticky Bone in alveolar ridge preservation

详细描述

Within 6 months after tooth extraction, the remaining alveolar ridge undergoes varying degrees of absorption, resulting in a decrease in horizontal width and vertical height of the alveolar ridge. The three-dimensional size change of the alveolar socket may affect the implantation of later implants and cause aesthetic and functional problems. Alveolar ridge preservation can maintain the volume of the alveolar socket, prevent soft tissue from growing into undesirable positions, slow down the absorption of the alveolar ridge to some extent, promote new bone formation, and maintain the shape of the extraction socket. This is crucial for later implant treatment for missing teeth. In this experiment, after non-traumatic tooth extraction, the blank group underwent natural healing, and the Bio-Oss Collagen group underwent alveolar ridge preservation using Bio-Oss Collagen and the Sticky Bone group using Sticky Bone, respectively, to verify the application of Bio-Oss Collagen and Sticky Bone in alveolar ridge preservation
