Although their etiology has been attributed to heavy occlusal forces, this article presents a case where opposing occlusion did not exist and patient's history revealed that the dehiscence was aggravated after removal of opposing teeth thus suggesting a strong relation between degree of dehiscence and lack of occlusal forces. http://pubs.sciepub.com/ajmcr/3/1/5/ajmcr-3-1-5.pdf collision rollover drifting steering control car spin and shunt
