For larger edentulous areas, fabricate a palatal template by using an existing removable prosthesis. When fabricating the palatal template, the buccal aspect is inclined from the incisal edge or central fossa of the proposed teeth back to the crest of the alveolar ridge, which is represented on a duplicated prosthesis as the greatest concavity on the alveolar ridge side of the prosthesis

Insert denture into alginate in denture duplicator

Apply separating medium

Fill other side with alginate

Close and allow alginate to set

Open and remove denture

Fill alginate mold with acrylic

Close and allow acrylic to set

Open and remove duplicated denture

Draw a line in the middle of each tooth and a line representing greatest concavity on the tissue side

Cut a 2.0mm wide groove in center of each tooth joining the lines representing the middle of each tooth and greatest concavity of the tissue side

Remove the buccal acrylic along the slope joining the two lines representing the middle of each tooth and greatest concavity of the tissue side

Trim excess incisal length to prevent interference with head of handpiece

Template determines mesio-distal positioning. Availability of bone determines final bucco-lingual angulation
