Category 74 Australasian Dentist clinical Reinforcement Quartz fiber compacted composite. MDT: Angelo Di Franco Removable prosthesis made in Peek. (Dr. Oriol Canto-Naves, Technos Dental Laboratory) Carbon Fiber/fiber quartz Grids are another new option for repairing and reinforcing dentures. MDT: Angelo Di Franco Images about overdenture made using Peek (Zirkonzhan. Germany) laboratories for dental use is the quartz fiber Daicom Quartz Fiber, in filaments for use by muffle. In this case, the best option is to use it with a compacted composite covering, which provides us with a very functional, durable, aesthetic, and economical prosthesis. For a removable prosthesis over teeth 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 Glass fiber and Carbon Fiber discs. Framework (monolithic) make with Glass Fiber. implant producing gingival 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. u For a full list of references contact gapmagazines@optusnet.com.au
