Figure 3.

Single implant placed in 1.5 site (4.5 × 6 mm): (a) pre-operative radiograph before implant placement; (b) radiograph obtained at time of placement; see augmented sinus floor (sinus lift = 3.33 mm); (c) radiograph obtained at time of loading; (d) radiograph obtained at 3-year follow-up; (e) Radiograph obtained at 5-year follow-up. See minimal graft resorption after 3 years and stable bone levels with minimal changes between 3-year (RCBH = 6.5 mm; sinus lift = 3.1 mm) and 5-year follow-up (RCBH = 6.2 mm; sinus lift = 2.8 mm).
