A retrospective study on clinical outcomes of implant -supported rehabilitations in patients with alveolar cleft

Abstract

<p>PURPOSE: To retrospectively evaluate the clinical outcomes of implant-supported prosthesis in alveolar cleft patients. METHODS: A total of 14 patients with alveolar cleft underwent implant restoration in Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine from January 2015 to January 2023 were collected. Among them, 9 were male and 5 were female. The age ranged from 18 to 52 years, with a mean of（26.1 ±10.6） years. The sequence treatment history of patients with cleft lip and palate and the effect of implant repair were retrospectively analyzed.RESULTS: Bone grafting in the fissured area failed repeatedly in 1 patient and no implant was implanted. A total of 21implants were implanted in the remaining 13 patients with alveolar cleft, all of which achieved good osseointegration. In 10cases, one implant was implanted in each fissure area for single crown or single end bridge repair. In 3 cases, 11 implants were implanted in the non-fissure area for fixed bridge repair. Seven patients with single implant were followed up for 6 to96 months, with an average of（39.4±29.2） months. During their visits, patients underwent various examinations, including pink aesthetic score（PES） averaging 10.16±0.98, white aesthetic score（WES） averaging 8.50±1.23, and probing depth（PD）with a mean of（2.68±0.61） mm. Additionally, gingival index（GI） was recorded with a mean of 1.33 ±1.10, and marginal bone loss（MBL） was measured with a mean of（0.17±0.35） mm. The width of the mid-labial keratinized mucosa was observed to be（5.14±2.10） mm. CONCLUSIONS: Implant-supported prosthesis in the alveolar cleft area after well-established multidisciplinary sequential treatments have predictable middle-term success rate, satisfactory aesthetic outcomes and stable peri-implant soft and hard tissue conditions.</p>

目的：对牙槽突裂患者种植修复的临床效果进行回顾性分析。方法：收集 2015 年 1 月至 2023 年 1 月在上海交通大学医学院附属第九人民医院进行种植修复的牙槽突裂患者 14 例。 其中，男 9 例，女 5 例；年龄 18～52 岁，平均（26.1±10.6）岁。 对患者唇腭裂序列治疗史及种植修复效果进行回顾分析。 结果：1 例患者裂隙区植骨反复失败，未植入种植体。其余 13 例牙槽突裂患者共植入 21 颗种植体，均获得良好骨结合。其中，10 例在裂隙区各植入一颗种植体进行单冠或单端桥修复；3 例在非裂隙区域植入 11 颗种植体进行固定桥修复。 7 例植入单颗种植体患者在修复完成后随访 6～96 个月，平均（39.4±29.2）个月。 随访期种植体及冠修复的留存率为 100%，粉色美学评分（PES）平均为 (10.16±0.98）分，白色美学评分（WES）平均为(8.50±1.23）分，牙龈指数（GI）平均为 1.14±1.12，探诊深度（PD）平均为（2.69±0.56） mm，边缘骨丧失（MBL）平均为（0.17±0.35） mm，角化龈宽度平均为（5.14±2.10） mm。结论：经过完善的唇腭裂多学科序列治疗后，牙槽突裂种植修复能获得良好的中期成功率，修复体美学效果和种植体周软硬组织稳定。
