Maxillary premolars extraction

Maxillary premolars extraction

(A) Maxillary premolars are removed with the No. 150 forceps. The hand position is similar to that used for anterior teeth. (B) Firm apical pressure is applied first to the lower center of rotation as far as possible and to expand crestal bone. (C) Buccal pressure is applied initially to expand the buccocortical plate. The apices of roots are pushed lingually and are therefore subject to fracture. (D) Palatal pressure is applied, but less vigorously than buccal pressure. (E) The tooth is delivered in the bucco-occlusal direction with a combination of buccal and tractional forces.
