[The effect of bite lowering after extractions on the mobility of front teeth]

The author, after pointing out the importance of supporting zones and height of bite to normal occlusion, discusses the possible consequences to front teeth of bite lowering subsequent to extractions. It is possible to show that there is a causal relationship between extractions of molars and loosening of front teeth. For early occlusal contacts, grinding-in treatment is recommended where the supporting structure is still intact and prosthetic treatment, after loss of the supporting structure.
