The aim of this study was to report the use of extra-short and short implants in combination with Guided Bone Regeneration (GBR) to rehabilitate a case of severe mandibular reabsorption. A 55-yearold female patient asked for a fixed implant supported rehabilitation in 4.5 - 4.6 zone which showed severe atrophy. It was decided to use an extra-short 4 mm length and 4.1 mm Ø, Roxolid and SLActive implant (Straumann Standard Plus Regular Neck, Institut Straumann AG) in 4.5 position and a short 6 mm length and 4.8 mm Ø, Roxolid and SLActive implant (Straumann Standard Plus Wide Neck, Institut Straumann AG) in 4.6 position. The implants supported cemented fixed prosthesis. Examinations were performed at the day of the surgery and up to 7-years in function to evaluate implant stability and periapical radiography. One extra-short implant and one short implant were placed. After 7 years in function no biological or prosthetic complication were recorded. Within the limitation of this case report, the use of short and extra-short implants to support fixed prosthesis seem to be a feasible treatment alternative in severe mandibular atrophy.
本研究旨在报告使用超短植体和短植体结合引导骨再生（GBR）来修复严重下颌骨吸收的病例。一位 55 岁的女性患者因 4.5-4.6 区严重萎缩而要求固定植体支持修复。决定在 4.5 位置使用长度为 4 毫米、直径为 4.1 毫米的 Roxolid 和 SLActive 植体（Straumann Standard Plus Regular Neck，Institut Straumann AG），在 4.6 位置使用长度为 6 毫米、直径为 4.8 毫米的 Roxolid 和 SLActive 植体（Straumann Standard Plus Wide Neck，Institut Straumann AG）。植体支撑着固定修复体。在手术当天和功能 7 年内进行检查，以评估种植体稳定性和根尖射线照相。放置了一个超短植体和一个短植体。功能 7 年后，未记录到任何生物学或修复体并发症。在本病例报告的限制范围内，使用短植体和超短植体来支撑固定修复体似乎是严重下颌骨萎缩的一种可行的治疗选择。
