Summary
This 3-year study found no significant differences between titanium and coated dental implants. While plaque improved, slight bone loss occurred around implants, which showed more mobility and bleeding than natural teeth.
Area of Science:
- Dental Implantology
- Biomaterials Science
- Periodontology
Background:
- Dental implants are a common tooth replacement option.
- Commercially pure titanium and coated implants are widely used.
- Long-term clinical outcomes and comparative analyses are essential.
Purpose of the Study:
- To compare the clinical and radiographic outcomes of commercially pure titanium implants versus coated implants.
- To evaluate implant performance against natural teeth over a 3-year period.
Main Methods:
- A 3-year prospective study involving 59 titanium implants and 19 coated implants in 59 subjects.
- Comparison with internal control teeth.
- Assessment of plaque index, probing depths, bleeding on probing, relative attachment levels, mobility, and bone height.
Main Results:
- No statistically significant differences were observed between titanium and coated implants.
- Improved plaque scores and slight bone loss around implants were noted over time.
- Implant sites exhibited less mobility but greater probing depths and bleeding on probing compared to control teeth.
Conclusions:
- Both titanium and coated dental implants demonstrate comparable long-term efficacy.
- Dental implants may present increased risks for periodontal issues compared to natural teeth.
- Further research into implant surface modifications and peri-implant health is warranted.
