目的:回顾性观察大直径种植体(5.5毫米以上)在后牙区种植修复的长期稳定性,牙龈形态,软组织覆盖和患者满意度。方法:选择在我院使用大直径种植体植入手术并修复3年以上的176例患者(207枚种植体)作为研究对象,观察并评价种植及修复后牙龈形态,种植修复牙冠功能及患者满意度。结果:使用大直径种植体在后牙区种植修复的患者对义齿的形态,功能及舒适感等患者满意度均能获得满意的临床效果。讨论:牙槽骨量是否充分及种植部位的选择对后期修复效果有较大影响。结论:对于后牙区牙槽骨量充足的患者,使用大直径种植体在初期稳定性,修复后种植体周围软组织覆盖和减少食物嵌塞等方面均可获得更好的临床效果。
OBJECTIVE: To retrospectively observe the long-term stability, gum morphology, soft tissue coverage and patient satisfaction of large diameter implants (5.5 mm) implanted in the posterior area. Methods: A total of 176 patients (207 implants) who underwent surgery with large diameter implants in our hospital and who had been repaired for more than 3 years were selected as the study objects. Gingival morphology after implants and repairs were observed and evaluated. Implants and crowns were repaired Satisfaction. RESULTS: Patients who underwent implantation in the posterior area with large diameter implants had satisfactory clinical outcomes for patient satisfaction with denture morphology, function, and comfort. Discussion: Whether the amount of alveolar bone is sufficient and the choice of planting site have a greater impact on the effect of post-repair. CONCLUSIONS: In patients with a sufficient amount of alveolar bone in the posterior tooth area, the use of larger diameter implants leads to better clinical outcomes in terms of initial stability, soft tissue coverage around the implant, and reduction of food impaction.
