Recently there have been numerous innovations in the field of oral surgery, and among these, there has been great interest in piezoelectric surgery.
This procedure makes use of a new ultrasound instrument to perform osteotomies and osteoplasties. The main feature of ultrasound bone surgery is to have a selective cutting effect on bone tissue, with no effect on soft tissue.
This is especially convenient when it is necessary to perform osteotomies near delicate anatomical structures e.g. the inferior alveolar vasculonervous sheath or sinus membrane.
Another feature is to perform reduced-thickness cuts, which are more regular and neater if compared to those made by common surgical burs.
This is very close to how bone saws work, however it is possible to draw any osteotomic line pattern and have improved control of the insert during the procedure in the total assurance of not damaging soft tissues.
These features are particularly useful in oral bone surgery. Clinical applications will be shown in cases of extraction therapy and endodontic surgery, parodontal surgery, implant surgery, and maxillary sinus surgery i.e. sinus lifting with vestibular or crestal access.
The most significant clinical advantages are represented by the preservation of the nerves, and of soft tissues. Osteotomies carried out by ultrasonic micro vibrations promote outstanding tissue healing.
From a clinical point of view, the cavitation of cooling saline reduces intra-surgical bleeding and post-op oedema. Furthermore, the shock-wave impact on sensory neurotransmitters reduces post-op pain.
The presentation shows the many results of histological, bio-molecular and neurosensory research. The outcomes for the patient are remarkably reduced mobility and recovery period.
Furthermore we describe a new kind of piezoelectric tools (Tipholder DBbasic insert and the Mectron Crown prep tips terminal insert) for a correct preparation of the natural abutment and also able to perform an elliptical-like movement thus enabling its functioning independently of the position of the tip with respect to the tooth, which represents the main disadvantage during tooth preparation, and also to evaluate the smoothness of prosthetic teeth preparation using these new piezoelectric instruments. It's a technique for the preparation and finishing of subgingival margins well shaped and non-traumatic with the preservation of the soft tissues.
Thanks to the ultrasound vibrations and the tip holder flexibility different crown prep tips can be used, combine it with the shape of the Crown prep tips that allow an optimal control, ergonomics and a clear view on the preparation field.
The result is positive impressive especially for the high aesthetic in restoration and the short recovery time of the patient.
