Resumen
Introduction: vertical resorption of posterior maxilla is a therapeutic challenge for dentists, since regenerative techniques are necessary to be able to place dental implants. Atraumatic sinus lift augmentation allows simultaneous dental implants placement to regenerative procedure, but it is not clear nowadays if it is or not necessary to use associated graft materials. Bone gain: scientific evidence reports a bone gain of 1-6.8 mm without using graft materials, versus 3.07-8.5 mm when authors use graft materials in atraumatic sinus lift augmentations procedures. Marginal bone loss: similar bone loss is expected in both techniques, but atraumatic sinus lift augmentation presents 0.5-1.54 mm when graft material is not used, versus 0.7-1.67 mm when graft material is used. Implant survival: both techniques present similar survival implant rates, greater than 90 %. Complications: low complications rate is reported, being the most frequent complication Schneider membrane perforation. Nevertheless, dental implant placement is possible in spite of this complication. Conclusions: atraumatic sinus lifting without graft materials presents lower bone gain and marginal bone loss in comparison to atraumatic sinus lifting with graft materials. Both techniques present similar survival implant rates and low complication rates, so using or not grafting materials should be decided analyzing all these variables.
