Abstract

Aim

CBCT and CAD/CAM technologies have allowed the development of patient-specific implants requiring no drilling. This prospective study evaluated the safety and effectiveness of a novel, drill-free, one-piece root-analogue implant designed using a digital workflow and manufactured additively.

Materials and Methods

Patients with non-restorable maxillary anterior or premolar teeth requiring extraction and implant placement were included. Implant design was based on pre-extraction cone-beam computed tomography (CBCT) and optical impressions of the target tooth, adjacent teeth and opposing dentition, and post-extraction scanning of the extracted tooth. Within 14 days post extraction, the implant was designed, manufactured and placed into the alveolar socket, and a temporary crown was installed out of occlusion. The final crown was installed after 3 months. Clinical parameters, including plaque index, gingival index, bleeding on probing, suppuration, peri-implant mucosal margin position, probing depth, probing depth relative to the implant platform and keratinised tissue, were collected at 3, 6, 9, 12 and 24 months post loading. Radiographic measurements as well as patient- and clinician-reported outcomes were also assessed.

Results

The study cohort comprised 12 patients. The cumulative implant survival and success rates reached 100% and 90%, respectively. Clinical and radiographic parameters consistently indicated healthy peri-implant tissues. Patient-reported outcomes demonstrated high satisfaction and minimal discomfort. Visual analogue scale (VAS) scores for overall satisfaction remained high, with a median of 10 at final restoration delivery (95% CI: 10.00–10.00) and at the 24-month follow-up (95% CI: 9.70–10.01).

Conclusion

These patient-specific, root-analogue implants demonstrated both safety and effectiveness, along with high patient satisfaction rates up to 24 months post loading.

患者特异性单件无钻全数字化设计牙种植体的早期植入：可行性研究。

AIMCBCT和CAD/CAM技术使得无需钻孔的患者特异性植入物得以开发。这项前瞻性研究评估了一种新型、无钻孔、一体式根模拟种植体的安全性和有效性，该种植体采用数字工作流程设计，并采用增材制造。材料与方法包括上颌前磨牙或前磨牙不可修复，需要拔牙和种植体的患者。种植体设计基于拔牙前的锥形束计算机断层扫描（CBCT）和目标牙齿、相邻牙齿和对牙列的光学印象，以及拔牙后对拔牙的扫描。拔牙后14天内，设计、制作种植体并将其放置在牙槽窝中，并安装临时冠以避免咬合。3个月后安装了最终的冠。于加载后3、6、9、12和24个月收集临床参数，包括菌斑指数、牙龈指数、探诊出血、化脓、种植体周围粘膜边缘位置、探诊深度、相对于种植体平台和角化组织的探诊深度。放射测量以及患者和临床报告的结果也进行了评估。结果研究队列包括12例患者。累积种植体成活率为100%，成功率为90%。临床和影像学参数一致显示种植体周围组织健康。患者报告的结果显示高满意度和最小的不适。视觉模拟量表（VAS）总体满意度评分仍然很高，在最终修复交付时（95% CI: 10.00-10.00）和24个月随访时（95% CI: 9.70-10.01）的中位数为10。结论：这些患者特异性的根模拟种植体具有安全性和有效性，并且在植入后24个月患者满意度较高。

期刊介绍： Journal of Clinical Periodontology was founded by the British, Dutch, French, German, Scandinavian, and Swiss Societies of Periodontology. The aim of the Journal of Clinical Periodontology is to provide the platform for exchange of scientific and clinical progress in the field of Periodontology and allied disciplines, and to do so at the highest possible level. The Journal also aims to facilitate the application of new scientific knowledge to the daily practice of the concerned disciplines and addresses both practicing clinicians and academics. The Journal is the official publication of the European Federation of Periodontology but wishes to retain its international scope. The Journal publishes original contributions of high scientific merit in the fields of periodontology and implant dentistry. Its scope encompasses the physiology and pathology of the periodontium, the tissue integration of dental implants, the biology and the modulation of periodontal and alveolar bone healing and regeneration, diagnosis, epidemiology, prevention and therapy of periodontal disease, the clinical aspects of tooth replacement with dental implants, and the comprehensive rehabilitation of the periodontal patient. Review articles by experts on new developments in basic and applied periodontal science and associated dental disciplines, advances in periodontal or implant techniques and procedures, and case reports which illustrate important new information are also welcome.
