case_images: In addition, we applied navigation to enable precise and accurate surgery performance [Figure 1].

case_images: Furthermore, AxiEM Emitter  was fixed to the surgery table for tracking the navigation probe [Figure 2].
case_images: The location of the impacted tooth in the maxillary bone was confirmed on the cortical bone using the navigation system. The navigation system screenshot shows a multiplane view of the surgeon's navigation probe, positioned in relation to the impacted tooth

case_images: Since the lesion was completely covered with bone, we used the navigation system to accurately determine the position of the impacted tooth and lesion [Figure 3].
case_images: (a) Using the navigation pointer, a bone-cutting line was established to provide adequate range for reliable lesion removal and the appropriate form for cortical bone removal. (b) A piezosurgery device was used to cut a precisely defined bone window. (c) The osteotomized bone window was removed, and the impacted tooth and lesion were clearly visible. (d) After removing the teeth, the bone lid was returned to its presurgical position

case_images: Using the navigation pointer, a bone-cutting line was established, on the basis of the adequate range for reliable lesion removal and the appropriate form for cortical bone removal [Figure 4a]. To allow access to the teeth and lesion, piezosurgery was used for the osteotomy to cut a precisely defined bone window using the computer-assisted navigation system [Figure 4b]. The osteotomized bone window was removed, allowing for the clear visualization of the impacted tooth and lesion, which were then removed [Figure 4c]. Following the visual confirmation of undamaged adjacent tissues, the bone lid, comprising the temporarily removed cortical bone, was repositioned to its presurgical position and fixed with a bioresorbable plate [Figure 4d].
case_images: Postoperative computed tomography (a; axial image and b; three dimensional image) confirmed a perfect maxillary bone recovery in the same morphology as before the operation
