Contact with Mandibular Second Molar
If space exists between the second molar and the impacted third molar, the extraction will be easier, However, if the tooth is a mesioangular or horizontal impaction, it is frequently in direct contact with the adjacent second molar. To
remove the third molar sa fely without injuring the second• molar, the surgeon must be cautious with pressure from elevators or with the bur when removing bone. If the second molar has caries or a large restoration or root canal, the surgeon must take special care not to fracture the restoration or
a portion of the carious crown (see Fig. 9-17, B)
