Features of the ideal implants
:Implants have to
• Induce healing and bone formation .
• Be easily removed if needed .
Have appropriate reactions with •
surrounding living tissues
• Resist the acting loads and probable
Resist the long-term actions like fatigue,•
• Be easily sterilized .
Possible problems upon
using the implant materials:
First Implant Design by Branemark
All the implant designs are obtained by the
modification of this design.
Dental implant materials
Titanium / Alloys
�Lightweight, corrosion resistant, easily
milled into different shapes, while
maintaining its strength.
�Forms layer of titanium oxide, which
is a stable and reactive interface that
becomes coated with plasma proteins.
�Ti-6Al-4V was alloyed to create a
biocompatible material with added
Dental implant materials
� An inert material with very low
� Has outstanding physical and
� Zirconia implants have proven high
level of osseointegration and bone-toimplant contact.
Dental implant surface treatment
Dental implants with rough surfaces
have been designed to improve
early healing, especially in areas of
poor bone or insufficient bone
�Coating implant surface with
different materials that can enhance
-Bone morphogenic protein.
Bone Quality relates to the degree of bone density present. Type 1 is
dense bone, which provides great cortical anchorage, but limited
vascularity. Type 2 bone is the best bone for osseointegration of dental
implants. It provides good cortical anchorage for primary stability, yet has
.better vascularity than Type 1 bone
.Types 3 and 4 are soft bone textures with the least success in type 4 bone
There are different approaches to place dental
implants after tooth extraction. The approaches
Immediate post-extraction implant placement.
Delayed immediate post-extraction implant
placement (2 weeks to 3 months after
Late implantation (3 months or more after tooth

When teeth are lost, bone will shrink
in several dimensions. Placing an
implant immediately can reduce
this bone loss and provide a

Who can provide implant supported
dental prosthesis ?
The general dentist is usually the first
resource for this service. The key is the
implant dentist’s training, experience
Competent dentists include
periodontists, prosthodontists and oral
surgeons who perform surgical and/or
