Chapter 12 Dental Implants
1 What are the 3 types of implants?
1. Subperiosteal
2. Transosteal
3. Endosseous
2. Which type of dental implant is placed under the periosteum
and rests on bone?: Subperiosteal
3. How many stages are in the placement of subperiosteal
implants?: 3
4. What happens during the first stage of placing subperiosteal
implants?: Incision made to expose bony ridge, impression taken
and incision closed
5. What happens during the 2nd stage of placing subperiosteal
implants?: Bony ridge replica made, framework with metal
projections is cast to fit over bone. 6. What happens during the
3rd stage of placing subperiosteal implant?: Re-open 1st
incision and expose bone. Framework is placed over bone and
, under periosteum. Tissues sutured with metal projections
protruding into oral cavity
7. What is a transosteal implant?: Horizontal beam attached
to metal rods, inserted into holes that have been drilled in the
mandible. Metal plate bolted to underside of mand. UNCOMMON
very invasive
8. When are transosteal implants used?: Support a
mandibular denture in a pt with severe resorption
9. What is an endosseous implant?: Titanium implant
surgically placed into bone 10. What is a cover/healing screw
and when is it used?: Prevents tissue from growing into screw
hole after implant covered with flap. Used in 2 stage placements
11. What is a healing abutment and when is it used?: Allows
gingiva to form a cuff around it while healing, used immediately
after 1 step stage, or in 2 step stage after 2-3 mo of healing
12. What is immediate placement of an implant?: Tooth
extracted, implant placed directly into socket. Site is covered with
