We investigated 322 patients, 20 and 40 old to find connections between the occurrence and localisation of facets, malocclusion and dynamic occlusion and estimated special aspects of periodontal reactions. The symptoms "anterior crowding", "increased overbite and overjet" didn't effect an increasing of frequency of facets in comparison with eugnathic denture. We found, that the facets decreased in lateral segments if the overbite became deeper and on the other hand number of facets increased with advancing years. The localisation of facets and occlusal guidance of dynamic occlusion coincided only in one third of investigated cases. Balancing and hyperbalancing teeth showed frequent facets. There was a direct relationship between increasing frequency and intensity of gingival retraction and the level of the abrasion of the hard tooth substance.
我们对322名年龄在20至40岁之间的患者进行了调查，以寻找小平面的出现与定位、错牙合及动态咬合之间的联系，并评估牙周反应的特殊方面。与正常牙列相比，“前牙拥挤”“覆牙合和覆盖增加”等症状并未导致小平面出现频率增加。我们发现，当覆牙合加深时，小平面在外侧段减少，另一方面，小平面的数量随年龄增长而增加。小平面的定位与动态咬合的牙合引导仅在三分之一的调查病例中一致。平衡牙和超平衡牙出现小平面的情况较为频繁。牙龈退缩的频率和强度增加与硬牙体组织磨损程度之间存在直接关系。
