The aim of this prospective case series was to assess the implant outcomes as well as hard and soft tissue dimensional changes of immediate implant placement in posterior sites using a custom-made sealing socket abutment (SSA) combined to peri-implant socket filling (PISF).
Twenty patients were considered for single extraction and immediate implant in upper or lower posterior regions. The remaining peri-implant sockets were filled with Deproteinized Bovine Bone Mineral. Based on intra-oral scans (IOS), custom-made SSAs were placed the same day. Implant survival rate, peri-implant bone changes, peri-implant health and pink esthetic score (PES) were recorded up to 1 year post-implant placement. Moreover, CBCT and IOS were performed to monitor hard and soft tissue dimensional changes.
One implant failed to osseointegrate leading to an implant survival rate of 95% after 1 year. Peri-implant bone changes yielded 0.19 ± 0.31 mm and 84.2% of the implants displayed no or mild bleeding on probing. Horizontal bone remodeling was not significant from baseline to 1 year at any levels. Finally, soft tissue profile was stable in the most cervical area while minor changes occurred during the first 6 months below the gingival margin. The absence of mid-buccal recession (0.07 mm) and good PES were found after 1 year.
Despite its limitations, this study showed that immediate implants in the posterior region using the SSA + PISF protocol resulted in promising implant outcomes with limited hard and soft tissue dimensional changes while decreasing the overall treatment time.
本前瞻性病例系列研究旨在评估使用定制密封基台(SSA)联合种植体周围 socket 填充(PISF)即刻植入后,种植体的植入效果以及软硬组织的维度变化。
20 名患者被认为适合在上颌或下颌后牙区进行单牙拔除和即刻种植。剩余的种植体周围 socket 用去蛋白牛骨矿物质填充。基于口腔内扫描(IOS),当天放置定制的 SSA。记录种植体的存活率、种植体周围骨变化、种植体周围健康状况和粉色美学评分(PES),直至种植后 1 年。此外,还进行了 CBCT 和 IOS 检查,以监测软硬组织的维度变化。
1 颗种植体未能骨整合,导致 1 年后种植体存活率为 95%。种植体周围骨变化为 0.19±0.31mm,84.2%的种植体探诊时无或仅有轻度出血。在任何水平,从基线到 1 年,水平骨重塑均不显著。最后,在牙龈缘以下的最初 6 个月内,软组织轮廓在最颈段保持稳定,而在该区域发生了轻微的变化。在 1 年后,发现颊侧无中度颊侧退缩(0.07mm)和良好的 PES。
尽管存在局限性,但本研究表明,在后牙区使用 SSA+PISF 方案即刻植入种植体可获得有前景的种植体效果,同时硬组织和软组织的维度变化有限,而整体治疗时间缩短。
