#A pedicle flap provides optimum visibility for extraction of the maxillary fourth premolar tooth.  

#A pedicle flap provides optimum visibility for extraction of the maxillary fourth premolar tooth. When making a vertical releasing incision mesial to the maxillary fourth premolar tooth, care must be taken not to incise through the infraorbital neurovascular bundle. A perpendicular rather than divergent incision is less likely to damage the infraorbital vessels and nerve.

#Once the flap has been raised, remove 1-3mm of bone from the alveolar margin overlying the buccal roots and identify the furcation.

#Section the tooth into 3 individual roots. Use a tapered bur on a high speed hand piece, beginning at the furcation and progressing coronally.
