business28 Show Preview IDS Cologne 2013 Unscrewing and bac- terial infiltration are known to be some of the major factors leading to implant failure. TheS1implantsystem manufactured and dis- tributed by the Italian company Safe&Simple is supposed to eliminate the risks of breaking im- plants and bacterial infiltra- tionbyaperfectlysealedand stable abutment-fixture con- nection. A modular design, enabling the clinician to customise the prosthesis and adjust it to all needs throughtheuseofstandard- isedcomponents,makesthe system also extremely ver- satile and price-competitive to other implant systems that are currently available on the market, the company said. According to Safe&Simple, its S1 system is based on 15 years of research conducted in collabora- tion with the universities in Modena and Reggio Emilia and was designed on the premise to make dental im- plantology “a streamlined, innovative and non-inva- sive practice with definite results”. The implants are cur- rently available in three diameters and in three lengths. They are indicated for immediate loading proce- dures, two-stage implant sur- gery as well as for partial and total edentulism. The system also comes withasurgicalguide,called Fly one, that uses a stereo- litographic model attached to the articulator. BasedinPievediSoligoon Northern Italy, Safe&Simple also offers regular and cus- tomisedtrainingcoursesheld in partnership with renown Italian dental schools and universities. Their implants will be on display during IDS in hall 10.2. SAFE&SIMPLE, ITALY www.safeandsimple.net Hall 10.2 Booth L065 As the R&D department of Glide- well Laboratories refines its proces- ses,aswellasimprovingthematerial’s translucency, aesthetics continue to improve. Advancements to improve the aesthetic properties of BruxZir Solid Zirconia restorations were re- cently achieved as demonstrated in this case by Dr Michael C. DiTolla, Newport Beach, Calif., USA. While Gidewell does not suggest that dentists suddenly switch all of their anterior restorations to BruxZir crowns, they may want to consider using it for patients with parafunc- tional habits or old PFMs, where an aesthetic improvement is essentially guaranteed, the company said. During the first appointment, the PFMcrownsontooth#8and#9(Fig.1) were removed with BruxZir Solid Zirconia crowns (Glidewell Laborato- ries). Then the shade was taken with help of the VITA Easyshade Compact which displayed the shade in both VITA Classical and VITA 3D-Master shades. Next, the selected 2M1 3D- Master shade tab was held to the tooth, along with the 1M1 3D-Master shade tab for contrast. The shade tabs in the mouth were photographed. PFG gel was placed intothesulcusoftooth#8and#9with anUltradentsyringe.Next,theywere anaesthetised with an STA Single Tooth Anesthesia System device. The RazorCarbidebureasilycutsthrough porcelain and metal substructures, and when used in combination with an KaVo ELECTROtorque handpiece, it easily cuts through the existing PFM. The crown was torqued with a Christensen Crown Remover. After using a periodontal probe to ensure there is enough biologic width to safely remove some tissue (Fig. 2), a NV MicroLaser was used to remove 1.5 mm of tissue. With the margins exposed, a 856-025 bur and KaVoELECTROtorquehandpiecewas used to drop the margins to the new gingival level. The dental assistant relined Bio- Temps Provisionals (Glidewell Labo- ratories) on tooth #8 and #9 with Luxatemp provisional material. Using a thin, perforated diamond disc, the gingival embrasures were opened to avoid blunting the interproximal papilla, as well as to make sure the gingival margins were not over- extended and the emergence profile was flat. TempBond Clear was used to cement the BioTemps, and loupes were used to inspect around the temps and gingival embrasures for excess cement. After two weeks, the temps were removed and the preps cleaned with a KaVo SONICflex scaler. After trimming the gingival margin with the diode laser, an Ultrapak cord #00 (Ultradent) was placed, cutting the cord intraorally on the lingual to avoid any overlap. A second cord (Ultrapak cord #2E) was placed before refining the preparation. As the top #2E cord on tooth #8 was packed, the top cord on tooth #9 ex- posed the margin (Fig. 3). Now finishing the preps begun using a fine grit 856-025 bur. TwomoistenedROEKO Comprecap Anatomic com- pressioncapswereplaced onthepreps.Thenthepatientbitwith medium pressure for 8–10 minutes. The Comprecaps were removed and the top cords pulled. For the im- pression, medium body impression material was applied around the preparations with a syringe and a bite registration was taken. Then the temporaries were replaced. Duringthethirdandfinalappoint- ment—another two weeks later—the temps were off, the BruxZir crowns were approved and a layer of de- sensitizer was placed on the teeth (G5All-PurposeDesensitizer).Awarm Air Tooth Dryer was used after apply- ing both coats of the G5, while the as- sistant placed Z-PRIME Plus inside the crowns.Thecrownswerethenloaded with a resin-modified glass ionomer cement (RelyX Luting Plus Automix) and seated, using a pinewood stick to ensure that they were fully seated and had the same length. In the “after” picture (Fig. 4b), there is not any porcelain on the BruxZir crowns.
