Why it matters for dental
Oral surgeons and implantologists performing lateral sinus floor elevation should note that graft voids detected on 6-month CBCT were linked to a higher implant failure rate (7.3 % vs 1.9 %) and lower cumulative survival (p = 0.014).
Key points
- 01
LASSO and multivariable logistic regression in 307 LSFE cases identified three independent risk factors for void formation: a specific graft material (OR = 4.02), increased graft amount (OR = 2.20), and smaller sinus-mucosa tension angle (OR = 0.98).
- 02
In a sensitivity analysis limited to conventional graft materials, graft amount remained a risk factor (OR = 2.02), with Stage III periodontitis and multiple-tooth units also associated, while membrane perforation was unexpectedly protective (OR = 0.30).
- 03
Kaplan–Meier analysis over a mean 46.6-month follow-up showed significantly reduced implant survival when voids were present (log-rank p = 0.014).
- 04
Voids were radiographically detected in 31.3 % of 307 patients who underwent LSFE between 2018 and 2023.
