The studies carried upon the pontic-mucosa relation, show that inflammatory changes take place in the adjacent soft tissue. It was also reported that inflammatory reactions were observed in the 95% of the cases following the removal of the prosthesis. In this study the clinical and histopathological data of the cases showing pontic designing complaining about their prosthesis, were evaluated. Clinically in almost all the bridges there was a question of collapsing and pressure upon the mucosa, particularly at posterior group bridges. The histopathological examinations of the sections taken from the underpontic mucosa having hyperemic appearance, showed bleeding regions, degeneration and descuamation in epithelium, and chronic inflammatory cell infiltration at the surface regions under epithelium. These findings prove the chronic inflammatory process in the mucosa under the bridge pontic.
关于桥体-黏膜关系的研究表明，相邻软组织会发生炎症变化。另据报道，95%的病例在去除假体后观察到炎症反应。在本研究中，对主诉假体问题的桥体设计病例的临床和组织病理学数据进行了评估。临床上，几乎所有桥体都存在黏膜塌陷和受压问题，尤其是后牙组桥体。对充血外观的桥体下方黏膜切片进行组织病理学检查，结果显示有出血区域、上皮变性和脱落，以及上皮下方表面区域的慢性炎性细胞浸润。这些发现证实了桥体下方黏膜存在慢性炎症过程。
