PURPOSE: To compare the effectiveness of 2 different techniques to lift the
maxillary sinus floor through a crestal approach on fresh human cadaver heads:
the Intralift technique using Piezosurgery and the Summers technique using
osteotomy.
MATERIALS AND METHODS: Two different protocols were simulated on 11 fresh human
cadaver heads or 22 maxillary sinuses. Inclusion criteria were: bilateral
edentulous maxilla with a residual ridge height between 3 and 9 mm. CT scans were
performed before and after surgery on all fresh cadaver heads. Both Intralift and
Summers techniques were performed on the same maxilla on the 2 sinuses. The
surgical procedure was performed by 2 independent operators, 1 experienced and 1
novice to compare the 2 results. The parameters assessed were the procedure
duration and the sinus membrane preservation.
RESULTS: The procedure duration was shorter when the operator was more
experienced (P = 0.03). There was a correlation between the operator dexterity
and the time required for surgery. The Intralift technique seemed safer for sinus
membrane preservation.
CONCLUSION: The Intralift technique is an interesting alternative to the Summers
technique.
