This study aims to show the long-time stability of straight and tilted implants loaded immediately with a provisional resin bridge followed by a definitive prosthodontic rehabilitation in edentulous jaws despite difficult hygiene conditions postoperatively.
This study included the participation of 23 patients and the restoration of 170 dental implants in 32 edentulous jaws. Patient data was analyzed from the start of treatment with a minimum follow-up period of 6 years in order to determine long-term implant success rates. However, the age of patients at time of surgery significantly affected the BOP to the detriment of younger patients (median 62 years old).
Although there was a higher risk of implant failure due to general disease, all the implants in this study survived successfully. As a replacement for a complete dental arch, the reduced number of implants in combination with the avoidance of augmentations reduces treatment costs. The immediate fixed prosthetic restoration of edentulous jaws thus represents a reliable therapeutic alternative to a two- to three-stage procedure. Optimized aftercare including professional teeth cleaning (PTC) (at least twice a year) can minimize the anamnestic effect of smoking, diabetes mellitus, and osteoporosis on BOP and possible bone loss.
本研究旨在表明，在无牙颌中，尽管术后卫生条件不佳，但即刻用临时树脂桥加载并随后进行最终修复的直形和倾斜种植体具有长期稳定性。
本研究纳入了23例患者，在32个无牙颌中植入了170颗牙种植体。从治疗开始分析患者数据，最短随访期为6年，以确定种植体的长期成功率。然而，手术时患者的年龄对探诊出血有显著影响，对年轻患者不利（中位年龄62岁）。
尽管由于全身性疾病种植体失败风险较高，但本研究中的所有种植体均成功存活。作为全牙弓的替代方法，减少种植体数量并避免植骨可降低治疗成本。因此，无牙颌的即刻固定修复是两阶段或三阶段治疗的可靠替代方法。包括专业牙齿清洁（至少每年两次）在内的优化术后护理可将吸烟、糖尿病和骨质疏松对探诊出血及可能的骨质流失的既往史影响降至最低。
