which is placed surgically into the jaw bone to
substitute for a missing tooth and its root(s).
In 1952, Professor Per-Ingvar Branemark,
a Swedish surgeon, while conducting research
into the healing patterns of bone tissue, accidentally discovered that when pure titanium comes into direct contact with the living bone tissue, the two literally grow together to form a permanent biological adhesion. He named this phenomenon "osseointegration".
All current implant designs are modifications of this initial design
STEP 1: INITIAL SURGERY
STEP 2: OSSEOINTEGRATION PERIOD
STEP 3: ABUTMENT CONNECTION
STEP 4: FINAL PROSTHETIC RESTORATION
• Fibroosseous integration
– “tissue to implant contact with dense collagenous tissue between the implant and bone”
• Seen in earlier implant systems.
• Initially good success rates but extremely poor long term success.
• Considered a “failure” by todays standards
Implant adapted to prepared site
Undisturbed healing phase
Hence the Epithelial surface attachment is IMPORTANT
Attention must be paid to both the coronal and interradicular spaces
