Guided magnetic-dynamic implant site preparation. A new opportunity in Digital Dentistry

---

Purpose

To check the accuracy and predictability of an innovative method for implant site preparation in guided surgery.

Methods

35 implants in 15 patients were planned in the maxilla. All the cases were planned with SMOP (by Swissmeda) and 2ingis guide (2ingis Belgium). The implant sites were prepared with magnetic-dynamic surgery (Magnetic Mallet by Osseotouch). A prototype was produced to adapt the tips of the magnetic-dynamic device to 2ingis guide. Some patients were selected for CBCT control and superimposition to check the accuracy of implant positioning.

Results

Of 35 implants inserted in 15 patients, only one, an implant inserted in the tuber, did not achieve osseointegration. After extraction, in a second operation after a 3-month wait, a new implant was placed, and it integrated successfully. The success rate is therefore 97%. The degree of accuracy of their positioning measured with the radiographic superimposition technique was found to be high with negligible discrepancies with respect to the planning. All treated patients reported very mild postoperative symptoms that were easily controlled with normal anti-inflammatory analgesic drugs.

Conclusions

The guided implant site preparation technique with Magnetic Dynamic (MM) technology combined with 2ingis surgical guides proved to be reliable and predictable and very well tolerated in terms of postoperative symptoms.
