In the early 1980s, industry forecasters predicted a boon in implant placement, a prediction that was premature for a market still in its infancy. Inadequate education, inconsistent techniques and unpredictable...See more results contributed to resistance on the part of many dentists and laboratories. However, by the time we entered the new millennium, implant treatment became the first choice in tooth replacement thanks to technical advancements, long-term success rates, and the abundance of manufacturer-provided education. The advent of CAD/CAM and cone beam technology further impacted the precision of implant placement with the development of sophisticated treatment planning software and surgical guides, making surgery more straightforward for the doctor and less traumatic for the patient. As of 2013, laboratories reported that two-thirds of their dentist-clients were prescribing implant restorations, according to LMT’s Implant Survey.

DENTAL TEAM: Gyu Cho, CDT, 3D BioCAD Milling Center, Renton, WA and Dr. Ronald Bryant, Seattle RESTORATIVE PROBLEM: The patient presented with severe occlusal wear on his natural teeth; the lower anterior...See more teeth were also very crooked and discolored. The existing crowns also exhibited wear, tissue retraction, dark margins and uneven shades from one crown to the next. Teeth #5, #12 and #14 were missing, requiring implants. TREATMENT PLAN: A full-mouth restoration with 28 units was proposed and had full compliance from the patient. The team opted to use gold-hue abutments to provide a very natural, warm appearance beneath the restorations—full contour 3D BioCAD zirconia for all the molars and 3D BioCAD zirconia copings with layered porcelain for all bicuspids and anterior units. 3D BioCAD was chosen because of the material's esthetics and translucency; the discs are manufactured using isostatically pressed Tosoh zirconia powder under high pressure from all directions, versus uniaxially-pressed zirconia powder which is pressed from only one direction. This provides a denser zirconia that eliminates any micro-voids in the material which can ultimately lead to failure; therefore, it's capable of being used for long-span bridges and other applications not possible with uniaxially-pressed discs. FABRICATION PROCESS: The models were scanned with a 3Shape D800 benchtop scanner and milled on a Roland 5-axis milling unit in 3D BioCAD's in-house milling center. After the units were milled and sintered, Cho used Zirkonzahn's shade liquid to enhance the translucency and natural esthetics of the shade. He then used Ivoclar Vivadent e.max Ceram Glaze Paste to easily achieve a natural-looking glaze.

DENTAL TEAM: Manfred Pörnbacher and Clemens Schwerin, Dentallabor Steger, Brunico, Italy and Dr. Lyndon Cooper, Professor and Chair at the University of North Carolina, School of Dentistry, Department...See more of Prosthodontics RESTORATIVE PROBLEM: A young female patient lost teeth #7 through #14 in a car accident and was already wearing a provisional restoration that had resulted in pronounced jawbone atrophy. TREATMENT PLAN: The team opted for a fixed superstructure supported by six implants at sites #7 and #8 and #11 through #14. Due to inadequate bone structure, the restoration would be an occlusally screw-retained, full contour Prettau® Bridge with a gingival flange. Prettau Zirconia was chosen because it resists chipping and is ideally suited for implant-supported restorations, situations with limited space and restorations with a gingival flange. FABRICATION PROCESS: The casts, waxup and articulated study casts were scanned using the S600 ARTI scanner. The articulator scan is used to check jaw relations so virtual casts can later be correctly occluded in the software; this allows static premature contacts to be identified with the matching virtual articulator in the software. The bridge was designed using Zirkonzahn.Modellier software; the positions of the screw access canals, values for the cementation gap and marginal region parameters were defined. The customized titanium bases were virtually modified to optimize the alignment of the screw-access canals, and the software automatically adapted the virtual waxup to the gingiva and implants. A resin provisional was milled. After several weeks, the necessary adjustments were made and the final bridge was milled using Zirkonzahn's M1 milling unit. The surface of the anterior teeth--#7 through #12--were manually cut back and customized. The incisal edges were left fully contoured to obtain edge protection and eliminate chipping. Acid-free Colour Liquids Prettau Aquarell were used for shading. The framework was placed under a drying lamp for about 40 minutes and sintered in the Zirkonofen 700 at 1,600°C. Gingiva-Composite was used in the gingival area. The technician applied Stain Colour Glaze Plus and, after the stain and glaze firing cycles, the customized titanium bases were cemented with dual-curing cement. For esthetic reasons, unit #7 simply rests on the implant and is not occlusally screw-retained because the screw access channel would have been visible on the labial surface.

DENTAL TEAM: Dr. William Roddy and in-house technician Steve Coles, Flow Laboratory, Fort Worth, TX RESTORATIVE PROBLEM: A 62-year-old female presented with implants on teeth #3, #4 and #5 and a PFM bridge...See more placed by another dentist. The implants had been placed too far buccally and the patient was unhappy with the esthetics and thickness of the bridge. The patient's occlusal planes were also uneven, and she had another large-span anterior bridge on teeth #6 through #11 that was starting to show signs of decay at the margins. TREATMENT PLAN: The team opted to remove both bridges and the remaining natural teeth in the arch. Additional implants were placed on teeth #6 and #11 through #14, and immediately loaded with a temporary bridge. After integration, the patient's final restoration would be a full contour, full arch, implant-supported bridge. KEROX ZircoStar zirconia in Extreme Translucent (ET) was chosen for its esthetics and ability to match natural teeth. Because of its small grain size, the material offers enhanced translucency and the ability to grind the finished bridge after final sintering if necessary. FABRICATION PROCESS: The case was scanned using the 3Shape D700 and designed in 3Shape's CAD software. It was milled using Sum3D CAM software on a Roland DWX-50 milling machine. In a Mihm-Vogt sintering oven, Coles used a slow rate of climb—three degrees per minute—to minimize warpage and shrinkage. Putting a 30-minute hold at 900°C was important; at that temperature, recrystallization of the ceramic begins and it allowed the thicker and thinner parts of the full arch bridge to reach even temperatures. For shading, Coles used Zirkonzahn's Colour Liquids Prettau® and let the bridge dry for 45 minutes under an infrared drying lamp. This step was critical to prevent the material from breaking in the early stages of sintering; moisture in the ceramic can abruptly transform into gas in the sintering oven and cause micro explosions, compromising the structure of the ceramic material. The restoration was completed with GC Initial stains and glaze. CONTACT: For more information, call Tamas Rozsa at Kerox at +36 23 382 006 or visit www.keroxdental.net.
