Narrow Ridge

A 75-year-old man requests implant placement at #21 several years after traumatic extraction (Fig.1) with the narrow ridge (Fig.2).  After ridge reduction ~ 3.5 mm (Fig.1,3), a 3.5x11 mm implant will be placed to avoid the Incisive canal (In in Fig.1,4) and the Mental Loop (M).  In fact the patient agrees to have guided surgery and then changes mind.
