Slide 1-

Chapter 15 DAE/DHE 203 Dental Implants
Slide 2-

Implants - defined Surgically inserted into bone Used as “anchors” to support a prosthetic Replace missing teeth in partially and/or fully edentulous areas May be single tooth or several teeth prosthetic Potential for ultimate stability for prosthetic Relies on integration with natural bone/tissues for retention and sustainability Video
Slide 3-

Implants – Basic Diagrams Prosthetics Implants
Slide 4-

Implants – Basic Diagrams Relies on integration with bone (new bone growth) for support. “Osseointegration” There must be a closed interface (implant to oral tissue) for success.
Slide 5-

Types of Implants: Endosseous – resides partially in bone Single tooth replacement thru denture support Screw-shaped Most common type
Slide 6-

Types of Implants:
Slide 7-

Types of Implants: Subperiosteal: rests on alveolar ridge, no bone invasion Less invasive, less stable Supports denture Transosteal: placed through the mandible (only) Attachments reside above ridge Rarely used
Slide 8-

Types of Implants:
Slide 9-

Types of Implants:
Slide 10-

Implant Materials: Titanium: Used as almost pure metal Corrosion resistant Strong & lightweight Great biocompatibility
Slide 11-

Implant Materials: Ceramics: Most biocompatible Formation of hydroxyapatite at surface Potential for chemical bond between bone & implant Coated Metals: Combines strength of metal with good interface potential of ceramic
Slide 12-

Implant Materials: Prosthetics & attachments: Crowns PFM’s most common Could be gold, ceramic, composite Attached by screws or cemented Dentures “Traditional” materials - acrylic Attached by various fasteners: clips, balls, screws, etc.
Slide 13-

Implant Materials:
Slide 14-

Placement of Endosseous Implant Soft tissue “flap” is laid Premeasured implant (body) placed into bone and covered entirely with soft tissue Healing: weeks - months
Slide 15-

Placement of Endosseous Implant The soft tissue is removed, exposing the implant, and a “healing cap” is placed Healing: several weeks
Slide 16-

Placement of Endosseous Implant Healing cap is removed and an abutment is placed Abutment is prepared (“post”/cylinder added) & impressed for prosthetic Sent to lab for fabrication Implant Abutment
Slide 17-

Placement of Endosseous Implant Crown (or other prosthetic) is seated with cement or screw (or other fastener)
Slide 18-

Procedure: Diagrams
Slide 19-

Patient Selection: Highly motivated, healthy patient Time-consuming procedure (months of healing post-sx) No systemic diseases or conditions that impact healing & sustainability of implant Substantial bone support Must be able to practice good OH
Slide 20-

Maintenance of Implants: Great OH by patient: Toothbrushes, floss, interdental aids, etc. Caution during prophylaxis: Scaling with conventional instruments may damage the titanium surface Sonic instruments are contraindicated! Use a very mild abrasive with rubber-cup prophy
