This technical review and case report describes the Minimally Invasive Vertical Incision Subperiosteal Technique (MIVIST) for use in specific targeted endodontic surgical cases.
The proposed MIVIST technique includes a vertical incision along with auxiliary vertical release incisions to enhance soft tissue healing during targeted endodontic surgery for teeth with small periapical lesions. The technique is described in a case report where a patient presented with persistent periapical periodontitis associated with a previously root canal treated tooth (#15). Based on the preoperative intraoral scan and cone beam computed tomography (CBCT) three-dimensional surgical guides were printed. A vertical main incision and additional release incisions were placed in the buccal mucosa of tooth 15 over healthy bone, with subperiosteal tunnelling then being performed to provide adequate access to the lesion and root apex. A guided osteotomy was carried out using the surgical template, followed by root-end cavity preparation and filling. The patient was followed up over 24 months, when excellent soft tissue healing as well as radiographic healing was apparent.
本技术综述和病例报告描述了用于特定靶向牙髓外科病例的微创垂直切口骨膜下技术（MIVIST）。
所提出的MIVIST技术包括一个垂直切口以及辅助垂直松解切口，以在针对根尖周病变较小牙齿的靶向牙髓手术期间促进软组织愈合。在一份病例报告中描述了该技术，该病例中一名患者患有与先前根管治疗过的牙齿（#15）相关的持续性根尖周炎。基于术前口腔内扫描和锥形束计算机断层扫描（CBCT）打印了三维手术导板。在牙齿15颊侧黏膜的健康骨上做一个垂直主切口和额外的松解切口，然后进行骨膜下隧道操作，以充分暴露病变和根尖。使用手术模板进行引导截骨术，随后进行根尖腔预备和充填。对患者进行了24个月的随访，此时可见软组织愈合良好且影像学显示愈合情况良好。
