A fibrous or flabby ridge is a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. It can develop when hyperplastic soft tissue replaces the alveolar bone and is a common finding particularly in the upper anterior region of long term denture wearers. Masticatory forces can displace this mobile denture-bearing tissue, leading to altered denture positioning and loss of peripheral seal. Forces exerted during the act of impression making can result in distortion of the mobile tissue. Unless managed appropriately by special impression techniques, such 'flabby ridges' adversely affect the support, retention and stability of complete dentures. This paper presents three case reports for prosthodontic rehabilitation of patient with flabby ridges with three different impression techniques.
纤维性或松软性牙槽嵴是影响上颌或下颌牙槽嵴的可移动软组织浅表区域。当增生的软组织替代牙槽骨时可出现这种情况，这在长期佩戴义齿者的上前部区域尤为常见。咀嚼力可使这种可移动的义齿承托组织移位，导致义齿位置改变和边缘封闭丧失。取印模过程中施加的力可导致可移动组织变形。除非采用特殊印模技术进行适当处理，否则这种“松软性牙槽嵴”会对全口义齿的支持、固位和稳定性产生不利影响。本文介绍了三例采用三种不同印模技术对松软性牙槽嵴患者进行口腔修复治疗的病例报告。
