F or almost two decades, MIMI®, the Minimally Invasive Method of Im- plantation, has been known as a beneficial, patient-friendly and periosteum-protecting surgery surgical method. (Don’t confuse the MIMI® method with Mini implants, which are made from titanium, grade five, and have an implant diameter that is smaller than 2.9mm). The Champions® im- plant system, which is inserted according to MIMI®, has been very successful in recent years. However, this implant system can also be inserted according to the classical implantation method, and if necessary, aug- mentations can be performed. The implants themselves are made from titanium, grade four, by a well-known Ger- man manufacturer. The sur- face of the Champions® are made from the best material on the market, according to several studies in Germany, for example at the university clinic in Cologne, and the Unit- ed States. The principle of Champi- ons® is KISS “Keep It Safe & Simple!” and last year, more than 50 000 Champions® im- plants were inserted in Ger- man dental clinics/offices. The Champions® implants have proven to be reliable and beneficial. Their price- performance ratio and inno- vative features (such as the cementable “Prep-Caps” and the two-piece Champions (R) Evolution® implants), as well as the efficient surgical and prosthodontic procedures they employ, are unbeatable. Primary stability at a torque of 40Ncm can be achieved with a one-piece 3.5mm-diameter “Classic” Champions® implant (slightly conical end), with the 3.0mm-diameter “New Art” Champions® or with 3.5mm- diameter two-piece Champi- ons (R)Evolution® implants. Implants with a larger diam- eter (approx 4.5mm or 5.5mm) should only be used if pri- mary stability of the 3.0mm- diameter condensers or of the mentioned implants cannot be achieved at 30/40Ncm. According to recent clini- cal studies, the old argument, “The more titanium in the bone, the better it is”, has been proven wrong. In fact, the peri-implant nutrition plays a major role. There are very few complications associated with the MIMI® treatment, which is very beneficial for patients: thanks to MIMI®, the perioste- um, which nourishes the bone, is very well protected. In some cases, you can ex- tract teeth that cannot be peri- odontally preserved and insert implants in the same ses- sion. Patients with one-piece Champions®implants, for ex- ample for single front teeth, are provided with a fixed tem- porary restoration before the final prosthodontic restora- tion is fitted eight weeks af- ter implantation. If there are more than four fixed teeth/im- plants, the final prosthodontic restoration can even be fitted within the first 14 days post- surgery and splinted/passive- ly fitted (eg with Implantlink Semi). In the two-eight weeks post-surgery, the one-piece implants must be stabilised against micro-movements in order to ensure the transition from Primary Osseo-integra- tion Stability (POS) to Second- ary Osseointegration Stabil- ity (SOS). This phase is very critical: when fitting fixed prosthodontic restorations, the temporary restorations should not be removed in the second to eight weeks post- surgery. When two-piece Champi- ons (R)Evolution® implants are inserted, the implants can be transferred to Secondary Osseointegration Stability in- dependently from temporary restorations without any prob- lems. Two-piece Champions (R)Evolution® implants are in- dicated for smaller units (one- three teeth), and one-piece Champions® are indicated for larger units (four or more im- plants/teeth). Dental surgeons prefer to work with two-piece Champions (R)Evolution® im- plants since they can avoid many of the problems associ- ated with temporary restora- tions. The whole treatment (without the need of special high-tech material) is easily affordable for most patients. • Figs 1-3: Case Study Tooth 34 and tooth 36 of the 50-year-old patient could not be preserved. After local an- esthesia, the teeth were gen- tly extracted, and one-piece Champions® were inserted. You can see the bone “pla- teau” between the previous tooth roots in the bifurcation area. This type of immediate implantation has many advan- tages, just one surgery session is necessary, and in the long- term, there is no loss of soft or hard tissue. • Figs 4-7 With the bone condensing con- ical triangular drills, we pre- May 7-13, 201216 Implant Tribune United Kingdom Edition Keep it safe and simple Dr Armin Nedjet examines the principles of Champions ‘According to recent clinical studies, the old argument, “The more titanium in the bone, the better it is”, has been proven wrong’ Fig 1 Fig 2 Fig 3 Fig 4 Fig 5 Fig 6 Fig 7 Fig 4
