常在上颌为总义齿下颌是双侧远中游离部分义齿的病人中看到一些特殊的口腔破坏性变化:(1)上颌牙槽嵴前部吸收,(2)上颌结节向下长,(3)硬腭组织乳头状增生,(4)下前牙突出,(5)活动部分义齿基托下的骨组织吸收,这些变化Kelly称其为“联合综合症”。此外,还有六个与之有关的变化:(1)垂直距离变短,(2)(牙合)平面不符,(3)下颌前移,(4)修复不适合,(5)沟隙龈瘤(epulus Fissuratum),(6)牙周变化。下颌双侧游离端义齿下的骨吸收是最先出现的症状,也是相当普遍的,因为下颌活动部分义齿下沉是逐渐的,病人很少查觉有问题,直至发现其他症状,病人是不要求诊
Often seen in the maxillary as the total denture mandibular distal partial denture patients have seen some special oral destructive changes: (1) maxillary alveolar crest absorption, (2) the maxillofacial nodules down long (( 3) papillary hyperplasia in the palate, (4) protrusion of the lower anterior teeth, and (5) absorption of bone tissue under the active partial denture base. These changes are described by Kelly as “combination syndromes.” In addition, there are six changes associated with it: (1) the vertical distance becomes shorter, (2) the occlusal plane does not match, (3) the mandibular advance, (4) the repair is not suitable, and Epulus Fissuratum, (6) Periodontal changes. Bone resorption under the bilateral free end of the mandible is the first symptom to occur and is quite common because the partial dentition of the mandibular move is gradual and the patient seldom detects the problem until the other symptoms are found and the patient is not required Clinic
