Hydrodynamic ultrasonic maxillary sinus lift: review of a new technique and presentation of a clinical case.
TL;DR: The main advantage of this new technique, Intralift, is that it does not require a minimum amount of crestal bone and the possibility of damage to the sinus membrane is minimised by using ultrasound based hydrodynamic pressure to lift it, while applying a very non-aggressive crestal approach.
Abstract: Objectives: Placing implants in the posterior maxillary area has the drawback of working with scarce, poor quality bone in a significant percentage of cases. Numerous advanced surgical techniques have been developed to overcome the difficulties associated with these limitations. Subsequent to reports on the elevation of the maxillary sinus through the lateral approach, there were reports on the use of the crestal approach, which is less aggressive but requires a minimal amount of bone. Furthermore, it is more sensitive to operator technique, as the integrity of the sinus membrane is checked indirectly. The aim of this paper is to review the technical literature on minimally invasive sinus lift and compare the advantages of different techniques with Intralift™, a new technique. Study Design: The present study is a review of techniques used to perform minimally invasive sinus lift published in Cochrane, Embase and Medline over the past ten years and the description of the crestal sinus lift technique based on minimally invasive piezosurgery, with the example of a case report. Results: Only eight articles were found on minimally invasive techniques for sinus lift. The main advantage of this new technique, Intralift, is that it does not require a minimum amount of crestal bone (indeed, the smaller the width of the crestal bone, the better this technique is performed). The possibility of damage to the sinus membrane is minimised by using ultrasound based hydrodynamic pressure to lift it, while applying a very non-aggressive crestal approach. Conclusions: We believe that this technique is an advance in the search for less traumatic and aggressive techniques, which is the hallmark of current surgery. Key words: Sinus lift, surgical technique, minimally invasive surgery, ultrasound surgery.

...To combine the advantages of a lateral approach sinuslift (scalable augmentation area and volume) with the atraumaticity of the transcrestal approach and to avoid the need of the surgeon to touch the sinus membrane with instruments or balloons in the detachment-process (and therewith eliminate one of the major risks of intrasurgical membrane perforation) and to utilize the well documented advantages of hydrodynamic pressure sinusmembrane-detachment [36,37] and atraumaticity of ultrasonic surgery, the transcrestal hydrodynamic ultrasonic cavitational sinuslift (tHUCSL-INTRALIFT) was developed in 2006 [38-40]....
