Abstract
Treatment of the posterior atrophic maxilla is a difficult task because of the low bone height and the invasiveness of the sinus-lift surgeries. Therefore, it is of interest to discuss the comparison of clinical outcomes of short dental implants (less than 6 mm) and sinus augmentation using longer implants (more than 10 mm) in 94 patients within 36 months. Also short implants demonstrated high survival rate of 96.6 compared to long implants which had high survival rate of 95.5 and marginal bone loss was similar but less complications and less time on treatment. Their clinical efficiency is demonstrated by the lowered morbidity and the similar success. Short implants can therefore be used as a valid and reliable option in the minimally invasive rehabilitation of the maxilla.
