Implant Dentistry Today 28 Reinforcement Quartz fiber compacted composite. MDT: Angelo Di Franco Carbon Fiber/fiber quartz Grids are another new option for repairing and reinforcing dentures. MDT: Angelo Di Franco or implants, usually the CoCr metal is the most common material, but we have another option if we want to avoid the risk to have allergy with the oral soft tissue: PEEK (poly-ether-ether-ketone). Over teeth the color of the framework is better than the metal and the weight is very low (9 gr. aprox). In these prostheses we have a problem with the hooks or clamps: we can’t tighten them. Over implants, different types of peek are used for the milled bar and for the framework. The friction between both frames are suitable to retain the prosthesis. CONCLUSION: The non-noble metals used in implant rehabilitations have a series of disadvantages: possible corrosion in contact with titanium of the dental implant producing gingival Removable prosthesis made in Peek. (Dr. Oriol Canto-Naves,Technos Dental Laboratory) Images about overdenture made using Peek (Zirkonzhan. Germany) inflammation, possible risk of allergy, genetic mutation or cancer, and a linear behavior that transfer the applied forces in greater quantity. With all this, it would be advisable, especially in large restorations, to use frameworks that do not contain non-noble metals. At this point, carbon fiber, glass fiber or quartz fiber provides us with a better biomechanical behavior that non- noble or zirconia material with a linear behavior, they are totally biocompatible, we eliminate the risk of allergies or corrosion and we achieve totally aesthetic prostheses, whether using resin teeth, composites, hybrid composites or lithium disilicate ceramics crowns cemented over it. n For a full list of references contact gapmagazines@optusnet.com.au a O PEN W IDE ® D ISPOSABLE & R EUSABLE M OUTH P ROPS The Open Wide ® Mouth Props facilitate oral care in variety of patients; Reusable Mouth Prop with saliva ejector has a con‐ venient ‘ wrap around’ handle to maintain control.
