Fig. 2_Pressure-, Frequency-, and Volume-Monitor. _Owing to the loss of vertical bone volumes in the maxillary sinus area, an implantation with suffi- cient primary stability is often not possible. In many casesatherapeuticalconsequenceisintroductionofa bone augmentation in the sinus area (sinus lift). Fear ofthisprocedureandhighercostsareoftenthecauses ofwhypatientsresisthavingthisoperationdone.Be- causeofthesereasons,ourdevelopmentmovedtothe next step. With the JEDER®-System it is possible to perform a sinus lift without the use of a scalpel. In comparisontotheconventionallateralfenestrationof the buccal sinus bone, in our procedure all one needs is a small opening on the crestal alveolar ridge. Over this opening it is possible to place the augmentation materialandtheimplantitself.Theriskofarupturein the Schneiderian membrane can also be reduced through this innovative technique. _Virtually bloodless procedure In order to place implants, maxillary bone sub- stancewithsufficientheightanddiameterisrequired.

Simultaneously the punch makes a small incrementation in the crestal bone in which the primary drill for implantation can gain purchase. The advantages in perforating of the soft tissue in this manner are: a clean access to the alveolar ridge and a minimal invasive procedure that makes a smaller wound, resulting in fewer traumas and less pain for the patient.
