In the field of oral medicine, the main donor site of autologous soft tissue transplantation is its own maxillary and palatal masticatory mucosa, and the thickness of the own mucosa often directly determines the success or failure of the operation. Therefore, if we can accurately evaluate the masticatory mucosa of the maxillary palatal side, it will provide an anatomical basis for clinicians to select the feeding site and make treatment plans for autologous soft tissue transplantation. Therefore, this article will affect maxillary palatal side related factors and the method for measuring the thickness of the soft tissue to conduct a comprehensive overview.
