可摘义齿床粘膜个别小区负荷过重、发生擦伤和褥疮性溃疡,病人对义齿不能适应,义齿功能降低,常需多次磨改,甚至促使义齿床粘膜和骨组织发生萎缩。为改善义齿的功能,必须在早期准确地查明因机械性负荷过重而引起的义齿床粘膜急性炎症区,按А.М.Чернух氏分期,在急性炎症1～2期(10秒至60分钟)已有组织充血和水肿。作者为早期发现负荷过重区,防止发生擦伤和褥疮性溃疡,给病人戴上可摘义齿后,立即嘱其进行强烈的咀嚼运动,然后义齿床粘膜用Schiller-Pisarev氏液(含碘)染色,经过3～5分钟,再涂甲苯胺兰液,随即能看到粘膜炎症区比正常区着色较强,呈现紫色至深紫色,着色强度取决于急性炎症程度。慢性炎症时其着色度更强。为对义齿基托进行适当的磨改,把义齿床粘膜负荷过重区准确地反映在相对的义齿基托组织画上,用软毛
Removable denture mucosa Individual cell overload, bruising and decubitus ulcer, the patient can not adapt to the denture, lower denture function, often multiple changes, or even promote the denture mucosa and bone atrophy. In order to improve the function of the denture, it is necessary to accurately and early detect the mucosal acute inflammation zone of the denture bed caused by overloading of the mechanical load. According to the stage of А.М.Чернух, 1 ~ 2 of acute inflammation (10 seconds to 60 Minute) has been congestion and edema tissue. The author found the overloaded area early to prevent bruising and decubitus ulcer, the patient wearing removable denture, immediately ordered strong chewing exercise, and then the denture bed mucosa with Schiller-Pisarev's solution (iodine) Staining, after 3 to 5 minutes, and then painted toluidine blue liquid, then you can see the mucosal inflammation than the normal area of strong coloring, purple to dark purple, the intensity of the stain depends on the degree of acute inflammation. It is more pigmented in chronic inflammation. In order to properly modify the denture base, the denture bed mucosa overload area accurately reflected in the relative denture base tissue painting, with soft hair
