sorbable membrane. Sensory changes after nerve repositioning seem to be less distinct after piezo- surgerycomparedtoconventionaldrillandoscillat- ingdevices.Nethertheless,atthefirstpostoperative visit, a clinical assessment of the nerve function is mandatory. Considering ethical and forensic implications, patients should be explicitly informed preopera- tively that nerve injury might be expected to occur. In combination with implant placement, also the potentialformandibularfracturemustbediscussed with the patient. The majority of our patients choose this treat- ment not in general anaesthetic or in intravenous sedation but just in local anaesthesia, which has proved to be reliably employable. In comparison to the application of conventional instruments pa- tientsdetecttheusageofpiezoelectricdevicesusu- ally less invasive. Accordingly, piezosurgery is well tolerated by the patients. Even in rare cases with persistent neurosensory deficits the patients were satisfied with the overall procedure. Summarizing can be inferred, that especially in complex situations with compromised bone bed, the inferior alveolar nerve transposition should be taken into account as a viable treatment modality for the attainment of individually optimized im- plant-supported reconstructions._ _References 1.Alling CC.Lateral repositioning of inferior alveolar neurovascu- lar bundle.J Oral Surg 1977; 35:419. 2.Jensen O, Nock D.
