A 4.5x20 mm implant is placed at #10 (Fig.7, 45 Ncm).   With implants at #3 and 4, the existing bridge is re-cemented as a provisional.

One month later, a 2.5x14 mm 1-piece implant and 3.5x20 mm implant (3x9 mm abutment) are placed at #8 and 9 (Fig.5).

Fig.8: three months after the 2nd placement.

Fig.18: 8 months post cementation.  There is no thread exposure associated with the 1-piece implant at #8.  More bone is deposited at the crest of the implants at #9 and 10.
