PROSTHETIC MINIMALLY INVASIVE STRATEGY FOR IMMEDIATE IMPLANTS: INSERTION AND IMMEDIATE PLACEMENT OF DEFINITIVE ABUTMENT FOR IMPLANTS RESTORED FOLLOWING THE PLATFORM SWITCHING PROTOCOL

A series of 15 clinical cases with 15 single Premium Kohno post-extraction implants in 15 patients, rehabilitated with Platform Switching, the “one-abutment one-time” technique and B.O.P.T. prostheses in the upper frontal area, showed excellent maintenance of hard and soft peri-implant tissues at 2 years, with an excellent aesthetic results. The combination of these three techniques showed itself therefore to be favourable for aesthetic areas.

This histological study in humans analysed the characteristics of soft tissues around the implant at 48 months, and compared implants rehabilitated with the switching platform concept to the traditional prosthetic protocol. The results showed that the switching platform protocol does not alter the soft tissues and that bone peaks are maintained.

This study demonstrated that implants restored according to the switching platform concept with mismatching of 0.25 mm maintained the same level of bone crest as traditional implants if the smooth part of the neck of traditional implants is left to emerge from the bone.

SURGICAL AND PROSTHETIC SWITCHING PLATFORM

One of the primary objectives of modern implantology is to maintain the crestal bone, so as to improve the aesthetic result and reduce the risk of late peri-implantitis. In comparison with traditionally designed implants, switching platform implants reduce early crestal bone loss in proportion to the size of the switch.
Switching platform implants are divided into two groups: implants with surgical switching (implants with a specially widened neck) and implants with prosthetic switching (implants with a standard neck with prosthetic posts having a reduced diameter). Both types of switching have proved to be effective and, in order to maximize the obtainable switch, for some years we have been using a switching platform protocol which combines the use of implants with surgical switching (Sweden & Martina Premium 3.80 SP implants) prosthesized with posts with a reduced diameter (posts for Premium 3.30). The combination of surgical and prosthetic switching has proved to be a valid and predictable protocol for minimizing crestal bone loss.
The clinical case illustrated below concerns the insertion of a single immediate post-extraction implant with immediate loading. Prosthetization was carried out according to the protocol described above.

Two groups of 20 patients received single implant in an edentulous site, which was rehabilitated in a second surgical procedure with a standard abutment (control group) and with the Switching Platform technique (test group). One year after the loading of the prosthesis, the test group showed a significantly lower loss of crestal bone compared to the control group.

Interesting review of the ability of platform switching to preserve periimplant tissues. The works included in the review allow it to be said that the protocols are effective in preserving marginal bone. However, other factors may contribute to this result, for example the apico-coronal position of the implant, the different implant surfaces and the extent of mismatching of the switching platform.
