“…Alveolar cleft is a bony defect that involves the maxillary arch. As a key step in the sequential treatment of cleft lip and palate, alveolar cleft repair aims at reconstructing the continuity of dental arch and overall alveolar process, providing bone support for adjacent teeth and unerupted teeth, and providing stable dental arch maxilla (Jensen and Stevens, 2020; Kato et al, 2021). Regarding cleft defects treatment, autogenous iliac cancellous bone graft has become the ideal treatment for the repair of alveolar cleft, providing abundant cancellous bone (Vura et al, 2020; Mahardawi et al, 2021).…”

Objectives: To present the use of dynamic navigation system in the repair of alveolar cleft. Patients and Participants: A total of three non-syndromic patients with unilateral alveolar cleft were involved in this study. Real-time computer-aided navigation were used to achieve restoration and reconstruction with standardized surgical technique. Methods: With the individual virtual 3-dimensional (3-D) modeling based on computed tomography (CT) data, preoperative planning and surgical simulation were carried out with the navigation system. During preoperative virtual planning, the defect volume or the quantity of graft is directly assessed at the surgical region. With the use of this system, the gingival periosteum flap incision can be tracked in real-time, and the bone graft can be navigated under the guidance of the 3-D views until it matches the preoperatively planned position. Results: Three patients with alveolar cleft were successfully performed under navigation guidance. Through the model alignment procedure, accurate matches between the actual intraoperative position and the CT images were achieved within the systematic error of 0.3 mm. The grafted bone was implanted according to the preoperative plan with the aid of instrument- and probe-based navigation. All the patients were healed well without serious complications. Conclusions: These findings suggest that image-guided surgical navigation, including preoperative planning, surgical simulation, postoperative assessment, and computer-assisted navigation was feasible and yielded good clinical outcomes. Clinical relevance: This dynamic navigation could be proved to be a valuable option for this complicated surgical procedure in the management of alveolar cleft repair.
