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

本回顾性研究旨在分析 2018 年 8 月至 2023 年 1 月期间，在萨萨里大学和波兹南大学，使用增材制造的骨膜下植入物对严重上颌萎缩患者进行全颌修复的一系列患者。共有 36 名患者和 72 枚植入物纳入研究，随访期间无植入物丢失，成功率为 90.3%。7 枚（9.7%）植入物出现 1 级暴露。6 个月时，10.4%的基台出现探诊出血，1 年时为 7.9%，2 年时为 10%，3 年时为 7%，4 年时为 11.4%。整个观察期间，基台下未发现明显的骨质吸收。基于本研究的结果，增材制造的骨膜下植入物可能代表一种安全可靠的技术，可用于严重上颌萎缩患者的全颌修复。
