Extended maxillary sinus augmentation to the apical area of the neighboring teeth: advantages and limitations
Objectives: The extension of sinus floor augmentation beyond the edentulous area, apical to the adjacent teeth, has many therapeutic advantages, but the reliability and safety of the procedure has not been assessed in depth. The present study compares the gain of bone anterior and posterior to the edentulous area and evaluates its potential advantages and limitations in the clinical setting.
Methods: The maximum vertical bone height in the edentulous and the extended maxillary sinus augmentation (EMSA) areas and the thickness of the schneiderian membrane of 65 patients were measured. Those measurements were analyzed using the t-test and Pearson’s correlations.
Results: The average vertical bone gain was 11.98 ± 3.53 mm in the edentulous sinus area and 8.60 ± 3.89 mm in the EMSA area (P < 0.05). Four patients had minor perforations of the schneiderian membrane. There were no post-surgical graft contaminations or peri-radicular changes during follow-up.
Conclusions: EMSA is a reliable and safe procedure with a very low complication rate.
