What is the edentulous Pin Guide protocol?

Seating: Seat it like a denture. Use indicator to find the perfect seat, and account for swelling from anesthesia-related inflammation. Hold it firm with two or more people, using solid, consistent pressure. Do not use a surgical mallet until all pins have been pushed in as far as finger pressure allows . Malleting too early puts uneven pressure on the Pin Guide / Fixation Base assembly.

Flap sequence (standard protocol): Do not flap first. Seat the Pin Guide, drill all the sites, remove the Pin Guide, then flap, re-seat, and insert the pins. If a flap is made first, follow the case-specific instructions exactly . Typically a ridge incision with the top of the ridge flapped forward. Keep the palatal portion of the ridge intact until after the Fixation Base is pinned. With no labial support, take extra care that the Pin Guide seats very accurately.

Verifying vertical: If the Pin Guide is a replica of the denture, seat it and mark the nose and chin to verify final prosthetic accuracy. (This won't work on a double arch where the Pin Guide has an integrated bite, since the vertical isn't centric.)

Double-edentulous options — both are acceptable; follow the flapping instructions included with each case:

  1. Complete the upper surgery and prosthetic conversion first, then the lower. The mandibular Pin Guide carries a bite designed for the finished maxillary temporary, so use the maxillary teeth to seat the mandibular Pin Guide.
  2. Seat both Pin Guides initially and drill all maxillary and mandibular sites. Complete the maxillary case, then flap the mandibular arch.
