Objectives: Sinus floor augmentation using transalveolar techniques is a successful and predictable procedure. The aim of the study was to compare the performance of conventional hand instruments using mallets and osteotomes with that of piezoelectric-hydrodynamic devices for maxillary sinus floor elevation. Material and methods: In 17 undamaged cadaver heads on randomly allocated sites, Schneiderian membrane elevation was carried out transcrestally using piezosurgery and a hydrodynamic device or by conventional hand instrumentation. After simulation of sinus augmentation by the use of a radiopaque impression material, a post-operative CT scan was carried out and volumes were determined. Statistic significant differences between the two methods were evaluated by nonparametric Mann-Whitney U-test with P < 0.05. Results: A mean graft volume of 0.29 ± 0.18 cm³ (0.07-0.60 cm³) was measured for the Summers' technique compared to 0.39 ± 0.32 cm³ (0.05-1.04 cm³) for the Sinus Physiolift® technique. There is no statistically significant difference with regard to trauma to the Schneiderian membrane or augmented volume. Conclusions: Both techniques generate expedient augmentation volume in the posterior atrophic maxilla. The piezoelectric technique can be recommended as an alternative tool to graft the floor of human maxillary sinuses. [ABSTRACT FROM AUTHOR] |
