prostho 2 lesson 2

Question 1

ANATOMIC CONSEQUENCES

Answer 1

1. Loss of ridge volume both in height and width
   2.Greater mandibular bone loss than maxillary bone loss
2. Bone loss is more pronounced posteriorly than anteriorly
3. Bone loss creating broader mandibular arch and constricted maxillary arch.
4. Attached gingiva of the alveolar bone can be replaced with less keratinized oral mucosa, which is more readily traumatized.

Question 2

PHYSIOLOGIC CONSEQUENCES

Answer 2

1. less muscular guidance
2. change in chewing pattern
3. altered lip support
4. reduce on facial heigh

Question 3

REQUIREMENTS FOR AN ACCEPTABLE
METHOD OF CLASSIFICATION

Question 4

CLASSIFICATION SHOULD FOLLOW RATHER THAN PRECEDE ANY EXTRACTIONS OF TEETH THAT MIGHT ALTER THE ORIGINAL CLASSIFICATION

Question 5

IF THE THIRD MOLAR IS MISSING AND IS NOT TO BE REPLACED, IT IS NOT CONSIDERED IN THE CLASSIFICATION

Question 6

IF THE 2ND MOLAR IS MISSING AND NOT TO BE REPLACED, IT IS NOT CONSIDERED IN THE CLASSIFICATION

Question 7

IF THE 3RD MOLAR IS PRESENT AND TO BE USED AS AN ABUTMENT, IT IS CONSIDERED IN THE CLASSIFICATION

Question 8

EDENTULOUS AREAS OTHER THAN THOSE THAT DETERMINE THE CLASSIFICATION ARE REFERRED TO AS MODIFICATIONS AND ARE DESIGNATED BY THEIR NUMBER.

Question 9

THE MOST POSTERIOR EDENTULOUS AREA ( OR AREAS) ALWAYS DETERMINES THE CLASSSIFICATION.

Question 10

NO MODIFICATION AREAS CAN BE INCLUDED IN THE CLASS IV ARCH

Question 11

THE EXTENT OF THE MODIFICATION IS NOT CONSIDERED ONLY THE NUMBER OF ADDITIONAL EDENTULOUS AREAS

Question 12

• partial denture that is cemented to natural
  teeth or roots which furnish the primary support to the prosthesis.

Question 13

a restoration or replacement which is attached
by a cementing medium to a natural tooth, roots, or implants.

Question 14

A branch of prosthodontics that is responsible in making an artificial appliance used to replaced a missing teeth and its contiguous structure in a partially edentulous mouth. This appliance can be placed and removed by patient at will.

Question 15

An artificial restoration used to replace a missing tooth or teeth and its surrounding structures in a partially edentulous arch.

Question 16

A tooth borne partial denture. A prosthesis that derived its support entirely to an abutment tooth/teeth.

Question 17

that branch of prosthodontics pertaining to the replacement of missing teeth and its contiguous structure in a completely
edentulous arch.

Question 18

Is that branch of prosthodontics that
deals with the treatment of facial defects.

Question 19

A dental prosthesis used in the course of short term intervals
for the reason of esthetics, mastication, occlusal support and
convenience for conditioning the patient for the acceptance of an artificial substitute for missing natural teeth until a more definite dental treatment can be provided.
