Denture retention may be defined as the ability of a denture to remain seated on the supporting tissues under various conditions. Soft tissue function influences the retention of removable prostheses by exerting pressure against the polished surfaces. The magnitude of this pressure on complete maxillary dentures under experimental conditions was studied. Five denture wearers participated. Miniature pressure transducers were placed at nine selected locations on the polished surfaces of the dentures: one on each tuberosity, three along the vibration line, and four on the vestibular flanges. The transducers were flush with the polished surfaces but discernible to the participants. Ultra-thin electrical wires connected the transducers to a power supply and recording equipment. Loading the incisors with 40 N in a cranial direction elicited soft-tissue pressure against the transducers. The highest values were recorded in the region of the tuberosities (51 kPa). Intermediary values were recorded along the vibration line (27 kPa), and the lowest pressure was recorded on the vestibular flanges (17 kPa).
义齿固位可定义为义齿在各种条件下保持位于支持组织上的能力。软组织功能通过对义齿磨光面施加压力来影响可摘义齿的固位。研究了在实验条件下全上颌义齿上这种压力的大小。五名义齿佩戴者参与了研究。微型压力传感器放置在义齿磨光面的九个选定位置:每个结节处一个,沿颤动线三个,前庭边缘四个。传感器与磨光面齐平,但参与者可以看到。超细线将传感器连接到电源和记录设备。沿颅骨方向对切牙施加40 N的负荷会引起软组织对传感器的压力。在结节区域记录到最高值(51 kPa)。沿颤动线记录到中间值(27 kPa),在前庭边缘记录到最低压力(17 kPa)。
