The use of fiberglass in dentistry has increased due to the improvements in the development of adhesive techniques reducing the cost of treatment and avoiding abutment tooth craving. The present study aims to evaluate the clinical usefulness of the new technique to fabricate a direct fiber-reinforced composite bridge (FRCB) over a long period of time. Twenty-one FRCB were performed with the new direct technique on 21 patients with a mean age of 58.85 years and female predominance in the Faculty of Dentistry of Oviedo (Spain). The framework design releases the embrasures allowing adequate interproximal brushing, avoidance of periodontal disease and interproximal caries. A baseline examination was performed and the patients were examined regularly at six-month intervals (nine years' follow-up). The restorations were also evaluated by an examiner using parameters to check their stability, longevity and the lack of periodontal disease. The most frequent location was the maxillary premolar region and the purpose of the restorations was to give a definitive bridge in 100% of the patients. Only one total debonding of the prostheses was detected during the observation period at 24 months and three partial adhesive-cohesive veneering composite fractures at the pontic after 60, 72 and 84 months, respectively. Kaplan-Meier was performed to detect the overall survival rate of the restorations at the end of the follow-up. Nine-year survival rates for the FRCB was 95.2%. All the cases had a clinically acceptable periodontal condition and an interproximal absence of caries in the abutment teeth. Currently, this type of restoration allows a minimally invasive aesthetic and is an affordable procedure, being a good alternative to other types of treatments.
由于粘结技术的发展进步降低了治疗成本并避免了基牙预备，玻璃纤维在牙科领域的应用有所增加。本研究旨在长期评估制造直接纤维增强复合桥（FRCB）新技术的临床实用性。在西班牙奥维耶多牙科学院，对21名平均年龄为58.85岁且女性占多数的患者采用新的直接技术制作了21个FRCB。框架设计释放了牙间隙，便于进行充分的邻间刷牙，避免了牙周疾病和邻面龋。进行了基线检查，并对患者每六个月定期检查一次（随访九年）。检查者还使用参数对修复体进行评估，以检查其稳定性、使用寿命以及是否存在牙周疾病。最常见的位置是上颌前磨牙区，修复的目的是为100%的患者提供确定性桥体。在观察期内，仅在24个月时检测到1例假体完全脱粘，分别在60、72和84个月时在桥体处检测到3例部分粘结-粘结性贴面复合树脂骨折。采用Kaplan-Meier法检测随访结束时修复体的总体生存率。FRCB的九年生存率为95.2%。所有病例的牙周状况在临床上均可接受，基牙邻面无龋。目前，这种修复方式具有微创美观的特点，且费用合理，是其他类型治疗的良好替代方案。
