1. Dental implants are commonly used to replace lost teeth and rely on osseointegration, the strong fixation of implants within bone, for stability and long-term survival. 2. Implant surface modifications at the macro, micro, and nano levels aim to improve early implant stability and shorten healing time through changes in surface roughness, coatings, and increased surface area to enhance bone formation and growth. 3. Common modification techniques include acid etching, blasting, sol gel coating, and anodization which alter surface topography at different scales to promote higher success rates compared to smooth surfaced implants.

Implant Surface modifications

2. Dental implants are widely used in dental practice to
replace lost teeth.
in 1960s, Professor Per-Ingvar
Brånemark introduced the term
"0sseonintegration". Which indicates
to strong fixation of implant within
bone.

3. osseointegration process is responsible for
implant stability and long term survival rate.
Dental implant especially with titanium material
shows high success rate.

4. Titanium is the most common material used as an
implant material.
- very compatible .
- shows good mechanical and chemical properties.

5. A lot of implant studies in the latest decades
discuss new implant designs and surface
modifications in order to:
- improve implant early stability and,
- shorten the healing time.

6. This is not just to increase implant success rate
but also to deal with some cases that complain
from medical problems that may effect the
osseontegration and healing process.

7. Implant surface modification can be basically
classified into three levels:
1- Macro-level surface modification.
2- Micro-level surface modification.
3- Nano-level surface modification.

8. Macro level modification:
Changes related to implant general design, for
example; screw threads.
The aim is to enhance initial implant stability and
bone in-growth.

9. Micro-level modification:
Surface treatment to make modification on the
surface within range of micro meters:
- To form film by using some coating materials like HA.
- To remove part of surface structure by using acid
etching or grind blasting.

10. Nano-level modification:
Get more attention in the latest years.
Surface modification within range of Nano
meters.
Can increase the surface area of implant.
Believed to improve bone formation process.

11. All this kind of modifications can change the
degree of surface roughness.
This roughness shows higher success rate when
compared with smooth surface implants.

12. The most common techniques used to apply this
modifications:
- Acid etching.
- Blasting.
- Sol gel.
- Anodization
