Abstract

Severe atrophy in isolated posterior maxillary sectors poses challenges for dental rehabilitation, especially in partially dentate patients where traditional graftless techniques are unsuitable. This study retrospectively analyzed the outcomes of sectional rehabilitation in 16 consecutive patients with Cawood and Howell class V to VI atrophy treated with 21 custom fabricated subperiosteal implants. Patients were followed for a median of 36 months (interquartile range: 24 to 48). Implant survival and success rates at 1 and 5 years were 95.2%, with minimal complications. Radiological assessments showed no significant bone resorption beneath abutments (mean: 0.18 mm at 1 year). Soft tissue health improved over time, with bleeding on probing affecting 10% of abutments at 6 months and only 2.5% at 4 years. These findings suggest that subperiosteal implants offer a viable graftless solution for sectional rehabilitation in partially dentate patients, combining high survival rates with favorable radiological and soft tissue outcomes. Further studies are needed to confirm long-term effectiveness.

定制的骨膜下种植体用于严重萎缩上颌的局部康复：技术说明。

上颌后部孤立区的严重萎缩给牙科康复带来了挑战，尤其是对于部分牙齿缺失的患者，传统的无移植技术并不适用。这项研究回顾性地分析了连续16名Cawood和Howell V至VI级萎缩患者使用21颗定制的骨膜下种植体进行切面修复的结果。患者的随访时间中位数为 36 个月（四分位间范围：24 至 48 个月）。种植体1年和5年的存活率和成功率均为95.2%，并发症极少。放射学评估显示，基台下方没有明显的骨吸收（1 年时平均为 0.18 毫米）。随着时间的推移，软组织健康状况也有所改善，6个月时有10%的基台探诊出血，4年时仅有2.5%的基台探诊出血。这些研究结果表明，骨膜下种植体为部分缺牙患者的切面修复提供了一种可行的无移植物解决方案，具有较高的存活率和良好的放射学及软组织效果。要确认长期有效性，还需要进一步的研究。
