In the previous articles in this series there has been an underlying theme about occlusion, although this has not been considered in the detail that this important subject deserves. I think it is fair to say that failure to attend to occlusal matters significantly reduces the life expectancy of the majority of restorations from crowns, through dentures to implants.
I have therefore set you 20 questions, all of which have relevance to occlusion. Do try to answer them. If you are not sure pass on to the next question. The answers will be provided in a later article, and more importantly the relevance of those answers to occlusion explained in depth.
Do please try to answer these questions rather than just going to the answers. You can learn much from a wrong answer that has been correcterd.
