Setting Up for Peg Lateral Restorations due to Tooth Size Discrepancy
Peg lateral incisors (Bolton Discrepancy): at times, for several reasons, the maxillary lateral incisors do not form properly. Maxillary lateral incisors are the smaller teeth on either side of the top two front teeth. This malformation of the tooth is genetically determined. The malformation can take on several different appearances, and both teeth or only one of the teeth may be affected. The teeth can be shorter in height or lesser in width or a combination of the two. This type of deviation from the normal shape of the tooth is called a peg lateral incisor. The solution to this cosmetic problem can be simple or complicated, depending on what shape the tooth has when it is diagnosed and treatment is begun. If the peg tooth (or teeth) is just slightly more narrow than normal and there is a space available on either side or both sides of it, the tooth can be bonded with a directly placed composite restorations.
