Less peri-implant bone loss in regenerated bone
10-year outcome of sinus lift and staged implant placements vs . implantation in native bone ¹
Retrospective case-series study with 86 patients
92 sinus lifts 209 implants
Implant predictability and complication rate after lateral window sinus lift using the sagittal technique
TREATMENT GROUPS Severe bone atrophy Moderate bone atrophy Control
0.1 – 3.5 mm 3.5 – 7 mm
Lateral sinus floor augmentation using Geistlich Bio-Oss ® and
Geistlich Bio-Gide ® and staged implant placement
Implants placed in native bone in the canine or premolar areas – no GBR needed
RESULTS AT 10-YEAR FOLLOW-UP
> Less peri-implant bone loss in regenerated bone vs native
Mean peri-implant bone level loss at 10-year follow-up ( weighted average )
> 98.6 % implant survival rate 3 implants failed within 10 years
> 3.35 % prevalence of peri-implantitis 7 implants – no difference between groups
> No complications in 97 % of the grafted sites Complications handled with antibiotics , graft rinsing and additional healing period
CONCLUSION
Reference
Severe atrophy
Moderate atrophy

Adequate soft-tissue management and optimal biomaterials selection lead to less wound dehiscence which in turn leads to less marginal bone loss around implants in regenerated bone .
