作者研究上颌前突、下颌前突和深覆(牙合)患者,牙列完整和牙列缺损时创伤(牙合)的特点。检查上颌前突(超(牙合))396例,下颌前突(反(牙合))141例,深覆(牙合)526例。单纯性创伤(牙合)损害:原来牙周组织健康者,其临床特点是:有龈炎,龈袋无分泌物,牙松动;X线检查,牙周间隙扩大,牙槽壁骨质吸收,牙槽间隔顶破坏,形成骨袋,周围无骨质疏松。深覆(牙合)患者常有单纯性创伤(牙合)损害,损害下前牙牙周组织;牙列完整的深覆(牙合)患者,后牙牙周组织没有明显病变;合并牙列缺损者后牙负荷过重并损害牙周组织。
The authors studied the characteristics of trauma (occlusion) in patients with maxillary protrusion, mandibular protrusion and deep overbite, complete dentition and dentition defect. There were 396 cases of maxillary protrusion (supramaxillary occlusion), 141 cases of mandibular protrusion (anti-occlusion) and 526 cases of deep occlusion. Simple trauma (occlusion) damage: the original periodontal tissue health, its clinical features are: gingivitis, gingival pocket no secretions, loose teeth; X-ray examination, periodontal space expansion, alveolar wall bone absorption, Alveolar septum damage, the formation of bone bags, no osteoporosis around. In patients with deep overbite (occlusal occlusion), simple traumatic occlusion often damages the periodontal tissues of the anterior teeth. There is no obvious pathological changes in the periodontal tissues of the deep occlusal dentition. The defect posterior teeth overload and damage periodontal tissue.
