Chapter 1: Rationale for Dental Implants

Question 1

Dental Implant Team:

Answer 1

1. Oral and maxillofacial surgeon - chooses implant and carries on with the implant procedure
2. General dentist/ restorative dentist - responsible for restoration/s
3. Dental technologist - responsible for the fabrication of prosthesis
4. Dental hygienist - responsible with the maintenance of the implant health
5. Dental nurse - supports all team members in all aspect of the patient’s dental care

Question 2

Zirconia can be an alternative to patients with:

Answer 2

• those with confirmed allergies to metal/s
• those who may have experience difficulties with titanium
• those who are adamant in maintaining a metal-free oral cavity

Question 3

Comparison titanium and zirconia implants:

Answer 3

1. Osseointegration of zirconia implants is inferior to titanium implants
2. Strength of zirconia implants is less than titanium implants
3. White color of zirconia implants ensures a better esthetic outcome than titanium implants

Question 4

Crystallized cubic form of zirconium dioxide and a widely known diamond stimulant.

Answer 4

Cubic zirconia

Question 5

Key points for response to geriatric patients:

Answer 5

1. Life expectancy of patient will extend for two more decades - particularly for non-smokers or normal weight
2. Current oral condition will generally worsen if not addressed or corrected

Question 6

Negative implications of aging process affecting the oral cavity:

Answer 6

• wearing away of tooth enamel
• medication-induced weakening of teeth
• susceptibility of teeth to disease processes
• tooth loss

Question 7

Leading causes of single posterior tooth loss/Primary causes of failure of crowns:

Answer 7

1. Carious lesions
2. Periodontal disease
3. Endodontic treatment

Question 8

Drawbacks of FPD:
(NARA)

Answer 8

1. Necessitates replacement when the prosthesis fails and/or abutment teeth are lost
2. Abutment teeth are susceptible to carious lesion
3. Requires additional pontics and abutment teeth when the bridge needs to be replaced
4. Abutment teeth with sound tooth structure are sacrificed

Question 9

NEGATIVE CONSEQUENCES OF RPD
Problems with RPD adult patients have reported:
(SDDA)

Answer 9

1. Survival rate is low
2. Deteriorating health of remaining teeth
3. Declining health of oral tissues that surround the remaining teeth
4. Accelerated bone loss in the edentulous space/s of denture wearers

Question 10

Ability or awareness to perceive the location, movement, and action of parts of the body.

Answer 10

Proprioception or kinesthesia

Question 11

Functional complex of organs and tissues found within the oral and craniofacial cavities.

Answer 11

Stomatognathic system

Question 12

Losing anterior teeth:

Answer 12

Demonstrates higher psychological and social disability effects

Question 13

Losing posterior teeth:

Answer 13

Shows higher physical complaints and functional deficits effects

Question 14

Refers to all the chemical reactions that continuously take place within the body to sustain life

Answer 14

Metabolism

Question 15

The amount of energy the body needs to maintain homeostatis

Answer 15

Basal metabolic rate (BMR)

Question 16

Types of cells that contribute to bone homeostasis:

Answer 16

Osteoblasts - bone formation
Osteoclasts - bone resorption
Osteocytes - mature bone cells that is derived from osteoblasts

Question 17

Basic facial types:

Answer 17

Brachyfacial - short facial type; facial height < facial width
Dolichofacial - long facial type; facial height > facial width
Mesofacial - ideal facial type; facial height is proportional to the facial width
