Abstract：
Background/Objectives: There is a need for alternative approaches to full-arch rehabilitation of atrophic maxillae. The aim of this short case series was to describe the technique and assess the short term-outcomes of atrophic maxillae rehabilitation using transnasal implants in conjunction with zygomatic implants. Methods: Three female patients (average age: 62 years) presenting comorbidities and atrophic maxillae preventing the insertion of standard maxillary anchored implants received a full-arch fixed prosthesis supported by transnasal implants together with zygomatic implants, using the ad modum all-on-4 concept. Patients were followed during the functional osseointegration period. Primary outcome measures were prosthetic and implant survival based on function. Secondary outcome measures were complication parameters (biological and mechanical), plaque and bleeding levels, and probing pocket depths > 4 mm. Results: No implant failures were registered, and all prostheses remained in function. The only complication was a fracture of a provisional crown that was resolved. Plaque and bleeding scores were mild during the follow-up period. Conclusions: The present manuscript describes the use of extra-long transnasal implants in combination with zygomatic implants in immediate function for full-arch fixed prosthetic rehabilitation of atrophic maxillae, with the objective of promoting more research into this relatively recent technique. More studies are needed to validate the technique.
摘要：
背景/目标：需要替代方法来进行萎缩性上颌骨的全弓康复。这个简短病例系列的目的是描述该技术，并评估使用经鼻植入物结合zy骨植入物进行萎缩性上颌骨康复的短期结果。方法：三名女性患者（平均年龄：62岁）出现合并症和萎缩性上颌骨，阻碍了标准上颌锚定植入物的插入，接受了经鼻植入物和zy骨植入物支持的全足弓固定假体。使用admodumall-on-4概念。在功能性骨整合期间对患者进行随访。主要结果指标是基于功能的假体和植入物存活率。次要结果指标是并发症参数（生物和机械），斑块和出血水平，和探测袋深度>4毫米。结果：没有记录植入失败，所有的假肢都能正常工作.唯一的并发症是解决了临时牙冠的骨折。随访期间斑块和出血评分均为轻度。结论：本手稿描述了使用超长的经鼻植入物与of骨植入物结合使用，以立即发挥功能，用于萎缩性上颌骨的全弓固定假体康复。目的是促进对这一相对较新技术的更多研究。需要更多的研究来验证该技术。
