A 3x12(2) mm 1-piece implant (vs. 3.8x8.5 mm 2-piece one) is placed at #30 and 3.8x16 mm 2-piece implant at #29 (Fig.5,6 with insertion torque >50 and <50 Ncm, respectively). The large distal defect at #29 (Fig.3,5 *, most likely due to post-related perforation) is later filled with bone graft (data not shown). After placing an abutment at #29 and suturing, perio dressing is applied. Mental Loop Last Next Xin Wei, DDS, PhD, MS 1st edition 06/19/2017, last revision 08/08/2021
