Ridge lap:
  • Advantage: esthetic
  • Disadvantage: inability to maintain oral hygiene resulting in inflammation
    • this type of pontic is contraindicated.
Modified ridge lap:
  • Advantages: good patient comfort, tissue support and allows access for oral hygiene.
  • Disadvantage: patient must have excellent oral hygiene
Sanitary (hygienic):
  • Advantages: hygienic, no contact of the ridge (2-4mm clearance)
  • Disadvantages: poor esthetics, inadequate tissue support for cheek and tongue, food trap, & tongue can play with space.
Bullet:
  • Advantages: fair access to interproximal areas & minimal contact with ridge
  • Disadvantages: poor esthetics, food trap can occur if it’s less than 2mm clearance from tissue.
Ovate:
  • Advantage: excellent esthetics (use when esthetics are in high demand)
  • Disadvantages: requires surgical preparation of the ridge or guided healing after extraction & increased difficulty with cleaning.
Perel (modified sanitary pontic):
  • Advantages: reinforces the connector region, decreases flexure, & decreases food retention.
  • Disadvantages: poor esthetics, inadequate tissue support for cheek and tongue, food trap & and tongue can play with the space.
Porter pontic:
  • Advantage: restricts the # of pontic embrasures
  • Disadvantages: fair esthetics (depending on lip line), whistling and hissing sounds can occur during speech, & increased cost of metal for substructure.
