What type of implant is shown?
Blade implant
What type of implant is shown here?
Cylindrical basket
What type of implant is shown here?
Titanium implant
What type of implant is shown here?
What does this image depict?
Radiographic appearance of a cylindrical root form implant
What does this image depict?
Soft tissue interface
What are the advantages of a titanium implant?
- Biocompatible
- Poor conductor
What are the disadvantages of a titanium implant?
- Soft, scratches easily
- Titanium particles in tissue causes an immunologic reaction in some patients: Periimplantitis, Periimplant mucositis
What is the purpose of an implant abutment?
- Attaches to the implant body
- Supports the restoration
- Transition btw crest of the bone and oral cavity
- Soft tissue adapts to the titanium or zirconia surface of the abutment
What is osseointegration?
- Implant to bone interface
- Absence of clinical mobility
- No pain or discomfort
- No increased bone loss
How is the implant to connective tissue interface characterized?
CT fibers are parallel to the implant surface
Fibers encircle the abutment like a drawstring
No PDL present
Keratinized tissue may or may not be present
Implications of an implant to CT interface?
Periodontal pathogens can cause inflammation and bone loss more rapidly along the implant surface
What is the biological seal?
- Where the soft tissue (epithelium) adapts to the abutment
- Acts as a barrier between the implant and oral cavity
areWhat is the differences between the tissue interface with a natural tooth vs. a dental implant?
- Implant has a biologic seal
- Implant lacks cementum
- CT around implant runs parallel, encircling implant
- Implant is osseointegrated, no PDL
What are the 4 periimplant diseases and conditions?
- Peri-implant health
- Peri-implant mucositis
- Peri-implantitis
- Peri-implant hard and soft tissue deficiencies
