  1. Most medical implants are
    completely surrounded by tissues
  2. What are the two most common indications for dental implants
    • Restoring an edentulous atrophic mandible
    • Restoring a single missing tooth
  3. What materials are used for Dental Implants
    • Titanium
    • Apatite-coated titanium
    • Metals
    • Ceramics
    • Polymers
  4. What is the most common material used in dental implants and what is an advantage
    • Titanium
    • Major advantage is that it will osseointegrate with bone - a biologic bonding of bone to the titanium
  5. _______ is another material used in implant that also osseointegrates
    Apatite-coated titanium
  6. What are the three types of dental implants
    • A.Endosseous or tooth-form implants
    • B.Transosseous or staple implants
    • C.Subperiosteal implants
  7. What type of implant is the most common
    Endosseous or tooth-form implants
  8. Describe the Endosseous or tooth-form implants
    Screwed or pressed into a hole made in the mandible or maxilla
  9. Describe the Transosseous or staple implants
    • used to stabilize mandibular dentures. A plate under the anterior mandible and several bolts through the mandible extend through the bone and gingiva into the oral cavity.
    • No longer used
  10. Where are subperiosteal implants used
    • used to stabilize a mandibular denture. Placed on the bone below the periosteum.
    • No longer used
  11. Osseointegration
    attachment of bone molecules, fibers, cells, and tissues to the implant
  12. For Osseointegration of dental implants what two properties are essential
    • Tissue compatibility
    • Interface with bone
  13. Biologic or perimucosal seal is an ________ that _________
    • attachment of epithelial cells to the implant
    • forms a barrier preventing microorganisms entrance to supporting tissues
  14. What are three properties essential for the placement of Endosseous Dental Implants
    • Surgical technique is critical to success
    • Don’t overheat the bone – will decrease ability to osseointegrate
    • Adequate bone is necessary to support the implant under occlusal load
  15. What are the steps to the two-stage implant placement procedures
    • 1. one surgery is to place the implant and cover it completely. Leave it covered for osseointegration to occur.
    • -There is no occlusal load and it’s protected from microorganisms
    • 2. second surgery uncovers the implant and places a “healing cap”, allowing epithelial tissue to form around it
  16. Single – Stage Implant Procedure is ________ used and can be described as the ______
    • widely
    • implant is surgically placed along with the healing cap extending through the tissue into the mouth
  17. The last phase of implants is the ______ phase where the _______
    • Prosthodontic
    • Healing cap is removed and the abutment is placed on to the implant
  18. The abutment is held into the implant by a ________ which is tightened to a specific amount of _______
    • screw (the abutment screw)
    • torque
  19. ________ is critical to osseointegration and maintaining the bone afterwards
    Occlusion
  20. In a critical _________, a temporary abutment, along with an ideally shaped temporary crown may be placed at the same time that the implant is placed
    esthetic zone (anterior),
  21. What are the four uses of implants
    • Restorative dentistry
    • Maxillofacial prostheses
    • Orthodontic uses
    • Orthopedic devices – titanium orthopedic devises (ex. hips, knees) use osseointegration for fixation
