Extraction canineupm4a
The document summarizes the steps for surgically extracting a maxillary 4th premolar tooth. The steps include: 1) sectioning the tooth into three segments - distal, mesiobuccal, and palatal, 2) elevating and extracting the segments routinely, and 3) curreting, flushing, and closing the surgical site.
