This report demonstrates the clinical use of a modified, truly anatomic, root analogue zirconia implant for immediate replacement of a right mandibular first premolar. A 22-year-old female patient with chronic apical periodontitis of the right mandibular first premolar was referred and the tooth was carefully extracted. A truly anatomical, root identical, roughened zirconia implant modified by macro-retentions was manufactured and placed into the extraction socket by tapping 3 days later. After 4 months a composite crown was cemented in place. No complications occurred during the healing period. A good functional and aesthetic result was achieved with minimal bone resorption and soft tissue recession at 18 months follow-up. This report describes the successful clinical use of an immediate, single stage, truly anatomical root-analogue zirconia implant for replacement of a single rooted tooth. Significant modifications such as macro-retentions yielded primary stability and excellent osseointegration. This novel approach is minimally invasive, respects the underlying anatomy and aids socket prevention. In addition the procedure saves time and cost, has good patient acceptance as there is no need for osteotomy, sinus lift or bone augmentation.
本报告展示了一种改良的、真正解剖学形状的牙根类似物氧化锆种植体在即刻替换右下第一前磨牙中的临床应用。一名患有右下第一前磨牙慢性根尖周炎的22岁女性患者前来就诊，该牙齿被小心拔除。3天后，制作了一个经过宏观固位改良的、真正解剖学形状、牙根相同且表面粗糙的氧化锆种植体，并通过敲击将其植入拔牙窝。4个月后，粘结了一个复合冠。愈合期间未发生并发症。在18个月的随访中，获得了良好的功能和美学效果，骨吸收和软组织退缩最小。本报告描述了一种即刻、单阶段、真正解剖学形状的牙根类似物氧化锆种植体成功用于替换单根牙的临床应用。诸如宏观固位等显著改良产生了初始稳定性和优异的骨整合。这种新方法微创，尊重潜在解剖结构并有助于拔牙窝预防。此外，该手术节省时间和成本，患者接受度良好，因为无需进行截骨术、鼻窦提升或骨增量手术。
