Planning & Placement of Implants

Question 1

what is osseointegration?

Answer 1

direct functional & structural connection between load bearing implant & bone

Question 2

what are the 2 stages of osseointegration?

Answer 2

primary osseointegration:
implant anchored in bone due to frictional forces provided between bone & implant design features

secondary osseointegration:
process of functional connection between bone & dental implant. Living bone grows onto surface of implant

Question 3

Tooth V Implant

Answer 3

Question 4

types of materials that can be used for dental implants?

Answer 4

• Titanium
• Titanium Zirconium (stronger than Ti)
• Ceramic implant

Question 5

does the implant design have an effect on survival/success on it?

Answer 5

tapered or parallel has no significant effect on success

Question 6

purpose of a dental implant?

Answer 6

• replace missing teeth
• primary aims of dental implant tx (aesthetic, functional concerns)

implant good for MISSING TEETH not a good replacement for a natural tooth

Question 7

how does smoking affect implants?

Answer 7

• increased risk of failure
• increased risk of peri-implantitis

affects:
- vascularity
- fibroblast/osteoblast function

Question 8

does age matter with implant placement?

Answer 8

• all implants should be placed after cessation of growth

Question 9

what impact does smile line have on implants?

Answer 9

• will impact on visibility of implant & prosthesis
• peri-implant soft tissue is the hardest area to mask

Question 10

what are relevant local anatomy for implant placement in the maxilla?

Answer 10

• maxillary sinus
• nasal floor
• nasopalatine canal
• infra-orbital nerve

Question 11

what are relevant local anatomy for implant placement in the mandible?

Answer 11

• Inferior alveolar canal
• mental foramen
• incisive canal
• lingual perforating vessels
• submandibular fossa

Question 12

what is the minimum amount of distance an implant needs from an adjacent tooth?

Answer 12

1.5mm MINIMUM (either side)
