Significant alveolar bone resorption follows tooth extraction. Immediate implant placement alone is not sufficient to prevent this phenomenon. The present study aims at reporting the clinical and radiologic outcome of an immediate implant with a custom healing abutment. In this clinical case, a fractured upper first premolar was replaced by an immediate implant and a customized healing abutment designed on the perimeter of the extractive alveolus. After 3 months, the implant was restored. The facial and interdental soft tissue was maintained with appreciable success after 5 years. The pre-and 5-year post-treatment computerized tomography scans showed bone regeneration of the buccal plate. Use of an interim customized healing abutment helps prevent hard- and soft-tissue collapse and promotes bone regeneration. This technique is straightforward and may represent a smart preservation strategy when there is no indication for adjunctive hard or soft tissue grafting. Given the limited nature of this case report, further studies are needed to confirm the present findings.
拔牙后会发生明显的牙槽骨吸收。单纯即刻植入术不足以预防这种现象。本研究旨在报告一种带有定制愈合基台的即刻植入物的临床和影像学结果。在这个临床病例中,一个折断的上颌第一前磨牙被一个即刻植入物和一个根据牙槽切除区域设计的定制愈合基台所取代。3 个月后,植入物被修复。5 年后,面部和牙间软组织保持了相当大的成功。治疗前和治疗后 5 年的计算机断层扫描显示颊板的骨再生。使用临时定制愈合基台有助于防止软硬组织塌陷和促进骨再生。该技术简单直接,在没有辅助硬组织或软组织移植适应证时,可能是一种明智的保存策略。鉴于本病例报告的局限性,需要进一步的研究来证实目前的发现。
