Patients and clinicians are becoming increasingly aware of the need to improve dental esthetics. After tooth extraction or trauma, there may be residual hard- or soft-tissue defects. These may be related to deficits in the bone or soft tissue. The evaluation of preoperative study casts, radiographs, and photographic documentation can aid the clinician in determining which types of augmentation are necessary. If adequate bone volume is present, the implants are placed according to protocol. Soft-tissue defects can be significantly reduced by implanting various biomaterials between the inner borders of the flap and surrounding bone. This case series describes patients who were successfully treated for soft-tissue defects with either demineralized freeze-dried bone or bovine bone.
患者和临床医生越来越意识到改善牙齿美观的必要性。拔牙或外伤后，可能会残留硬组织或软组织缺损。这些缺损可能与骨组织或软组织的不足有关。术前研究模型、X光片和照片记录的评估有助于临床医生确定需要哪种类型的增量手术。如果有足够的骨量，则根据方案植入种植体。通过在皮瓣内缘和周围骨之间植入各种生物材料，可以显著减少软组织缺损。本病例系列描述了使用脱矿冻干骨或牛骨成功治疗软组织缺损的患者。
