This report aimed to describe the simultaneous use of a computer\u2010assisted dynamic navigation (C\u2010ADN) system and piezoelectric bony\u2010window osteotomy for the transantral microsurgical approach of a maxillary left first molar with adequate root canal filling and symptomatic apical periodontitis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Summary<\/jats:title><jats:p>This case report highlights the importance of C\u2010ADN to carry out a minimally invasive buccal surgical access to palatal roots affected by apical periodontitis and provides a practical example to help clinicians make treatment decisions based on the available evidence. Clinical and tomographic evaluations were performed before the surgical procedure and at 24\u2010month follow\u2010up. This case was treated using a C\u2010ADN system fitted to a piezotome for the buccal approach of the buccal roots, maxillary sinus membrane lifting, and for transantral location, root\u2010end resection, cavity preparation, and filling of the palatal root. The navigation system allowed to achieve an accurate apical canal terminus location and root\u2010end filling of the three roots with a minimally invasive piezoelectric crypt approach. At the 24\u2010month follow\u2010up examination, the patient remains asymptomatic, with normal periapical structures, and regeneration of maxillary sinus walls. It was concluded that the combination of dynamic navigation with piezoelectric bony\u2010window osteotomy offers enhanced accuracy, tissue preservation, diminished risk of iatrogenic complications, and could maximize success and survival rates in transantral EMS.<\/jats:p><\/jats:sec>","DOI":"10.1111\/iej.14026","type":"journal-article","created":{"date-parts":[[2024,1,20]],"date-time":"2024-01-20T15:09:26Z","timestamp":1705763366000},"page":"490-500","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Dynamically
