Conditions
Interventions
experimental group:Using CGF to fill the extraction wound in the OAC area, covering it with a layer of CGF film, shaping the film to overlap with the edge of the extraction wound by 2-3mm, and fixing
control group:Fix the blood clot in the extraction socket using an 8-shaped suture.
