2 - Edentulous Maxilla and Mandible (complete)

Question 1

What is dentate, endentulous, and partially edentulous

Answer 1

dentate = having teeth or pointed conical projections
edentulous = without, or lacking teeth
partially edentulous = missing one or more teeth which require replacement

Question 2

what are the consequences of tooth loss

Answer 2

bone resorption
maxillary resorbs in vertical and palatal direction
mandible resorption is vertical and is oriented along the cross sectional shape of the mandible
ridge resorbs

Question 3

What happens to edentulous mandibular and maxillary arches

Answer 3

maxillary = resorption causes the arch to get smaller
mandibular = resorption causes the arch to get wider

Question 4

how does the amount of resorption compare in the maxilla to mandible

Answer 4

the mandible resorbs 4x as fast as the maxilla

Question 5

what will an ill fitting prosthesis do to resorption

Answer 5

increase the speed of resorption

Question 6

How can a mandibular denture cause dysesthesia

Answer 6

because as the bone in the mandible resorbs the proximity of the mental foramina to the alveolar ridge increases, and the denture may sit on top of the mental nerve coming out of the mental foramina
