Dental Implant
“A prosthetic device or alloplastic material implanted into the oral tissues beneath the mucosal and/or periosteal layer, and/or within the bone to provide retention and support for a fixed or removable dental prosthesis.”
Implant Categories
- Eposteal: on/around the bone
- Transosteal: through the bone
- Endosteal: in the bone
- ■EPOSTEAL - Subperiosteal
■TRANSOSTEAL-Transmandibular
■ENDOSTEAL - Blade and Root Form
subperiosteal implants
metal? supported by? cost? survival? indication? bone?
■Vitallium metal
■Denture is implant supported /expensive
■Survival rate 85% Ten years (Harvard Consensus)
■Indicated for atrophic edentulous mandible.
■Bone resorption leads to mobility infection and loss
transosteal implants

■Titanium metal
■91% Success rate at fifteen years (excellent)
■Only indicated for the edentulous mandible
■Denture is tissue supported
Requires one surgery usually in the hospital.
External incision / approach.
Excellent for the atrophic mandible where root form implants would weaken the jaw.
Complex surgical procedure therefore not widely used.
Restricted to the anterior mandible. (post=IA nn)
transmandibular implants

■Reversible?
■97% success rate
■used for Implant supported denture
■Used in severe atrophic mandibles <10mm
■Gold Alloy, not titanium
■Reversible – can be removed due to design of screws and degree of integration, but not easy process
