Periodontal regenerative treatment of intrabony defects in the esthetic zone often poses a significant challenge to clinicians. Various materials and techniques have been proposed to achieve periodontal regeneration. This article presents modified vestibular incision subperiosteal tunnel access (M-VISTA) for treatment of intrabony defects in the esthetic zone. Two cases were treated using the proposed approach with enamel matrix derivatives and demineralized freeze-dried bone allograft to optimize the regenerative outcomes without affecting the soft tissue profile in the esthetic zone. Two different indications were described with addition of acellular dermal matrix and specific suturing techniques based on each particular clinical scenario. Clinical and radiographic follow-up of 18 months revealed successful outcomes of the proposed minimally invasive approach with no postoperative gingival recession. Patient-centered outcomes were highlighted as another major consideration in periodontal regeneration.
美学区域骨内缺损的牙周再生治疗常常给临床医生带来重大挑战。为实现牙周再生，人们提出了各种材料和技术。本文介绍了改良前庭切口骨膜下隧道入路（M-VISTA）用于治疗美学区域的骨内缺损。使用该方法联合釉基质衍生物和脱矿冻干骨同种异体移植治疗了两例患者，以优化再生效果，同时不影响美学区域的软组织外形。根据每种特定临床情况，描述了添加无细胞真皮基质和特定缝合技术的两种不同适应证。18个月的临床和影像学随访显示，所提出的微创方法取得了成功，术后无牙龈退缩。以患者为中心的治疗效果被强调为牙周再生中的另一个主要考虑因素。
