【摘要】 本研究旨在通过3个年轻女性上颌前牙美学区单颗种植牙修复后10年随访,观察到种植牙相邻天然牙持续萌出影响美学修复效果及咬合功能,临床上表现为种植牙冠缩短,唇侧龈缘线与对侧同名牙不协调,唇系带偏斜,中切牙间出现缝隙,种植牙牙冠近远中牙龈乳头形态、高度改变,骨吸收,咬合异常等。主要归因于成年后牙槽骨持续发育、年轻成年女性继发生长高峰、牙周改建与牙齿萌出,并提出解决该问题的可行方法。更多还原

【Abstract】 This study aimed to analyze the esthetic outcome and infraocclusal complications resulted by the continuous maxilla growth of the tooth adjacent to the implant tooth via three different young female adults cases up to 10-year follow-up after implant tooth final restoration. The main complications observed in these cases were: shorter incisal edges, disharmony labial gingival margin with the contralateral tooth, labial frenulum deviations, diastema, or incomplete papillae, bone resorption, and infraocclusion. The causes attributed to dentoalveolar changes in adulthood, continuous growth spurts in young adult female, and periodontium remodeling. Finally, several solutions were proposed.更多还原
