前牙美学区种植义齿个体化修复及临床评价

目的:针对前牙美学区牙列缺损且修复条件异常的患者,选取不同修复方案进行个体化修复并评价其临床效果。方法:依据纳入标准,选取接受种植修复治疗并完成前牙美学区个体化修复的患者46例、共58颗种植修复体作为研究对象,随访3～24个月,观察临床效果并利用前牙区红白美学指标给予评分。结果:研究对象年龄18～69岁,平均随访期12.6个月。所有植体均获得良好骨结合,未见植体失败或种植体周围炎病例。依据红白美学标准评估3个月时种植修复体,红色美学低分段者占1.72%,中分段者占44.83%,高分段者占53.45%;白色美学低分段者占0%,中分段者占20.69%,高分段者占79.31%。结论:前牙美学区个体化修复方案可有效改善缺牙患者的外观,及时复诊随访和口腔卫生维护有利于避免种植体及修复体并发症,长期效果有待观察。

Individualized restorative designs and clinical evaluation for dental implants in the anterior esthetic zone with inappropriate conditions

PURPOSE: To offer individualized restorative strategies for patients receiving dental implants in the anterior esthetic zone but with inappropriate available conditions and evaluate the clinical outcomes. METHODS: Forty-six patients with 58 implants were recruited for the study in accordance with the criteria and received individualized implant prostheses in the anterior esthetic zone. The patients were followed up for 3-24 months, and the clinical outcomes were evaluated by pink and white esthetic scores (PES/WES). RESULTS: The patients were from 18 to 69 years old, and followed up for 12.6 months in average. According to the third month follow-up esthetic scores, for PES, 1.72% of the patients got low scores, 44.83% got medium scores and 53.45% got high scores; For WES, 0% got low scores, 20.69% got medium scores and 79.31% got high scores. No implant failure or peri-implantitis occurred. CONCLUSIONS: Individualized restorative designs for implants in the esthetic zone can effectively improve the appearance of the prostheses which originally have no appropriate available space. Close follow-up and monitoring of the peri-implant soft tissue and proper oral hygiene instructions are important to ensure the conditions of the prostheses.
