Abstract：
The aim of this retrospective study was to analyze a series of patients who underwent full-arch rehabilitation of the atrophic maxilla using additively manufactured subperiosteal implants, between August 2018 and January 2023, at the Universities of Sassari and Poznan. In total, 36 patients and 72 implants were included, with no implants lost during follow-up, and a success rate of 90.3%. Seven (9.7%) of the implants showed class 1 exposure. Bleeding on probing was detected in 10.4% of the abutments at 6 months, 7.9% at 1 year, 10% at 2 years, 7% at 3 years, and 11.4% at 4 years. No significant bone resorption under the abutments was detected during the whole observation period. Based on the findings from this study, additively manufactured subperiosteal implants could represent a safe and reliable technique for full-arch rehabilitation in patients with severe maxillary atrophy.
摘要：
这项回顾性研究的目的是分析一系列使用增材制造的骨膜下植入物对萎缩性上颌骨进行全弓康复的患者，2018年8月至2023年1月，在萨萨里和波兹南大学。总的来说,包括36例患者和72个植入物，在随访期间没有丢失植入物，成功率为90.3%。七个（9.7％）的植入物显示1类暴露。在6个月时，在10.4％的基台中检测到探查出血，1年的7.9%，2年10%,3年7%,4年为11.4%。在整个观察期间，未检测到基台下的显着骨吸收。根据这项研究的结果，添加制造的骨膜下植入物可以成为严重上颌骨萎缩患者全弓康复的安全可靠技术。
