Missing Teeth? Flashcards

1
Q

How would you restore this?

A

Missing: Central Incisor

  • FDP (Pontic: Modified Ridge Lap)
  • Resin-bonded retainers might be used if the patient is very young and if the abutments are healthy teeth that have never been restored

Q

How would you restore this?

A
  • Missing: Maxillary Central Incisor
    • Implant size: 4 X 12 mm
    • Large nasopalatine foramen may interfere with implant placement.
    • Loss of the facial bone plate may necessitate bone grafting
    • Restoration: Ceramic crown over a custom UCLA abutment or preparable abutment

Q

How do you restore this?

A
  • Missing: Mandibular Central Incisor
  • Abutments: Central Incisor and Lateral Incisor
    • Implant is best option
    • Resin bonded contraindicated if abutments are rotated or mobile
    • If abutment teeth are prepped, could easily encroach on pulp which would lead to post/core
    • Pontic: Ovate/Modified Ridge Lap

Q

How would you restore this?

A
  • Missing: Mandibular Central Incisor
  • Implant: 3.3 X 12 mm
  • Considerations:
    • Treatment of choice!
    • Ideal space would be 7.3 mm
    • If inadequate space is available…
      • Ext all mandibular incisors
      • Place two 4 X 12 mm dental implants in the lateral incisor position

Q

How would you restore this?

A
  • Missing: Maxillary Lateral Incisor
  • Abutments: Central Incisor and Canine
  • Considerations:
    • If the canine is long, periodontally sound, and pontic will not contact in centric relation or excursions, a single-abutment cantilever fixed partial denture could be used

Q

How would you restore this?

A
  • Missing: Maxillary Lateral Incisor
  • Implant: 3.5 X 12 mm
  • Considerations:
    • Loss of incisor typicall results in loss of facial plate of bone leaving a facial concavity, which leads to an implant being placed too far lingual - leads to poor implant emergence profile
    • Ideally, bone grafting then implant placement
  • Restoration: Porcelain crown over a UCLA abutment

  • Abutments: Central Incisor and Canine
  • Considerations:
    • Implant supported crown is the ideal choice
    • If FDP: potential pulpal involvment
    • Cantilever fixed partial dentures are not an option for the replacement of mandibular lateral incisors
    • If abutments are severely rotated/malposed, remove all mandiblar incisors then place canine to canine FDP
  • Retainers: Resin-Bonded Retainers
