The anterior mandible in #22-27 area have a lot of vasculature and anastomoses of the sublingual and submental arteries penetrating into the bone as seen on these CT scan images. These channels of blood vessels that continue inside the jawbone, are more pronounced in the mandibular symphysis area. I was wondering if someone could share their experience in perforating these channels upon placement of implants in anterior region of lower mandible, assuming no perforation has occurred with the lingual plate to lead to severe hematoma. I am planning to place 2 implants 4.3×10 or 3.5×10 in area 27 (26.5) and 26(25.5) using guided surgical technique to provide better stability for future CL denture which will be supported by 4 implants. Thank you for your assistance and your help in this matter would be greatly appreciated.
