Application of Sticky Bone and Bio-Oss Collagen in Alveolar Ridge Preservation

Application of Sticky Bone and Bio-Oss Collagen in Alveolar Ridge Preservation: A Randomized Controlled Clinical Trial

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

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 control group underwent alveolar ridge preservation using Bio-Oss Collagen and the experimental group using Sticky Bone, respectively, to verify the application of Bio-Oss Collagen and Sticky Bone in alveolar ridge preservation

The control group underwent natural healing, and the experimental group underwent alveolar ridge preservation using Bio-Oss Collagen and Sticky Bone, respectively.

Only the investigator knew about the grouping, and the subjects did not know whether they were an experimental or control group or blank group.

After non-traumatic tooth extraction, the control group will use alveolar ridge preservation with bio-oss collagen

After non-traumatic tooth extraction, the experimental group will use Sticky Bone for alveolar ridge preservation

Alveolar ridge preservation with bio-oss collagen is a surgical method that reduces or limits the physiological resorption of alveolar bone after tooth extraction by implanting bio-oss collagen in the socket and covering the biological barrier membrane.

Alveolar ridge preservation with sticky bone is a surgical method that reduces or limits the physiological resorption of alveolar bone after tooth extraction by implanting sticky bone in the socket and covering the biological barrier membrane.
