摘要/Abstract

摘要： 本文报告1例3D打印个性化钛网（3D-PITM）联合引导骨再生（GBR）在前牙美学区严重骨缺损数字化种植修复中的应用。患者因外伤导致前牙美学区天然牙连续缺失,伴严重骨缺损,美观及功能受显著影响。临床采用3D-PITM联合GBR术式进行骨增量,并在计算机辅助设计/计算机辅助制造（CAD/CAM）种植外科导板辅助下完成种植体植入及修复。结果显示：3D-PITM联合GBR术后6个月,11位点骨宽度由术前3.72 mm增加至7.31 mm,骨高度由术前14.11 mm增加至15.97 mm;21位点骨宽度由术前3.58 mm增加至7.41 mm,骨高度由术前11.97 mm增加至15.59 mm,实现了预期骨增量效果,重建了牙槽骨轮廓,为种植体“以修复为导向”的精准植入提供了充足骨量。术后随访期间成骨稳定,种植体边缘无明显骨吸收。分别于戴牙后即刻、6个月及12个月评估红色美学评分（PES）、白色美学评分（WES）及患者满意度的视觉模拟评分（VAS）,结果表明美学效果良好且稳定,前牙美观与功能均得到明显改善。

Abstract: This report presents a case of 3D printing individualized titanium mesh (3D-PITM) combined with guided bone regeneration (GBR) applied in digital implant restoration of severe bone defects in the anterior esthetic zone. The patient suffered from continuous loss of natural teeth and severe bone defects in the anterior esthetic zone due to trauma, which seriously affected appearance and function. The 3D-PITM combined with GBR surgery was performed for bone augmentation, and the implant was placed with the assistance of a CAD/CAM implant surgical guide and subsequently restored. Six months after 3D-PITM combined with GBR, the bone width at site 11 increased from 3.72 mm preoperatively to 7.31 mm, and the bone height increased from 14.11 mm preoperatively to 15.97 mm; the bone width at site 21 increased from 3.58 mm preoperatively to 7.41 mm, and the bone height increased from 11.97 mm preoperatively to 15.59 mm. The expected bone augmentation effect was obtained. The alveolar bone contour was reconstructed, and sufficient bone volume was provided for “prosthetic-driven” precise implant placement. Osteogenesis was stable during postoperative follow-up, and there was no obvious marginal bone resorption. The pink esthetic score (PES), white esthetic score (WES), and patient satisfaction visual analogue scale (VAS) were evaluated immediately after crown delivery, at 6 months, and at 12 months. The results showed that the esthetic outcome was good and stable, with significant improvement in anterior esthetics and function.
