Implant rehabilitation is a routine treatment for tooth loss. The mandibular anterior region exhibits unique anatomical characteristics, including high bone density, low proportion of cancellous bone, limited bone volume, labial undercuts, and variations in the mandibular lingual foramen. These features pose significant challenges to implant surgery in this area. Multiple studies have reported tha
