s10 - History of Rehab Flashcards
What is the significance of the Egyptian king’s copper peg in implant history?
First recorded metal implant (possibly post-mortem).
How did Hippocrates contribute to early implantology?
Documented re- and trans-implantation techniques (460 B.C.).
What was the major limitation of 18th-century alloplastic implants (e.g., gold/silver)?
High failure rates due to lack of osseointegration.
What did Brånemark discover in 1952, and why was it revolutionary?
Osseointegration of titanium; enabled modern endosseous implants.
Define homoplastic, autoplastic, and alloplastic implants.
Homoplastic: Same species; Autoplastic: Same individual; Alloplastic: Synthetic materials.
What are mucosal inserts, and where are they primarily used?
Metal/ceramic inserts engaging keratinized mucosa; mainly for maxillary prostheses.
List two contraindications for mucosal inserts.
Mucosa <2mm thick, uncontrolled diabetes.
Describe the design of subperiosteal implants.
Metal framework beneath mucoperiosteum with transgingival projections.
What was the 10-year success rate of subperiosteal implants (Bodine & Yansen)?
0.66
When are transosseous implants indicated?
Severely atrophic mandibles to retain removable prostheses.
How do ramus-frame implants differ from subperiosteal implants?
Engage mandibular symphysis + ramus (vs. resting on alveolar ridge).
Who introduced blade-vent implants, and what was their success rate?
Dr. Linkow (1966); 55% success.
Compare threaded vs. non-threaded root-form implants.
Threaded: Primary stability via threads (modern standard); Non-threaded: Press-fit (rare).
Why did threaded root-form implants dominate modern implantology?
Superior osseointegration, stability, and versatility.
What is the key takeaway from Brånemark’s work?
Titanium’s osseointegration enabled predictable, long-term implant success.
