In resorbed mandibles, the risk of injury to the inferior alveolar canal increases due to the need to maximize the limited amount of available bone.
In the first periapical radiograph (PAR), a drilling depth of 9 mm was observed, although the inferior alveolar canal was barely distinguishable.
In Image 2, a virtual implant placement was performed in three different positions. The silhouette of the mesial implant measures X mm, the central implant X mm, and the distal implant X mm.
This virtual implant positioning over the PAR enables the surgeon to intraoperatively assess different treatment options. The complete height of the mandibular ramus is clearly visualized on the radiograph, facilitating accurate evaluation of bone availability.
