There is 1-2 mm separation from the Mental Nerve (red dashed line) when two of 2x10(2) mm 1-piece implants are placed (Fig.4). Insertion torques of the mesial and distal implants are less than 25 and 15 Ncm, respectively. In fact bone graft is placed around the distolingual root of the tooth #30 after calculus removal (<). Following reduction of the abutments, periodontal dressing is applied locally.
More reduction is required for the distal abutment, because of the supraeruption of the opposing tooth, #4.
