Understanding the mechanisms of everyday processes, such as eating and cleaning, can help dentists and oral surgeons find the optimal methods for maintaining healthy teeth. Besides cosmetic considerations, dental restorations, such as crowns, need to last and provide years of pain-free, useful service. Evaluating the mechanical behavior of restorative materials is important in establishing their function.
Besides the fatigue and wear behavior of restorative and prosthodontic materials, the durability of the adhesives used in restorations are vital to implant longevity. Also, mechanical testing of orthodontic devices, such as braces, wires or posts, or general tissue products for gum and mouth disease, in the laboratory can help establish their performance and suitability in a clinical situation. In recent times, the use of dental implants has become an everyday occurance and the complex loading of these needs to be established within the laboratory environment.
