OMS Flashcards
How much bone loss around an implant is possible while still remaining successful?
0.2 mm annually after the first year
Distances an implant must be from other structures to be successful: Lingual cortical plate Maxillary sinus IAN Buccal cortical plate Inferior border of mandible Mental nerve Nasal cavity Adjacent tooth Adjacent implant
Buccal cortical plate: 1 mm Lingual cortical plate: 1 mm Maxillary sinus: 1 mm Nasal cavity: 1 mm Inferior border of mandible: 1 mm Adjacent tooth: 1.5 mm IAN: 2 mm Adjacent implant: 3 mm Mental nerve: 5 mm

What is the Verrill sign and what does it mean?

Where is the anesthetic going in a PSA block?
pterygopalatine space
When would you expect dry socket to occur?
3-5 days post-extraction
Which surgical movement of the maxilla is MOST unstable?
