Summary
This study compared six cements for retaining metal copings on titanium abutments. Panavia 21 showed the highest retention, while Temp Bond NE had the lowest, indicating cement choice impacts implant crown stability.
Area of Science:
- Dental Materials Science
- Biomaterials
- Prosthodontics
Background:
- Dental implant restorations require reliable cement retention for long-term success.
- Titanium abutments present unique surface characteristics influencing cement bond strength.
- Limited data exists on cement retention specifically for ITI solid titanium abutments.
Purpose of the Study:
- To evaluate and compare the retention strength of six different dental cements.
- To assess cement performance when bonding metal copings to solid titanium abutments.
Main Methods:
- Ten ITI implants with solid titanium abutments were used.
- Metal copings were cemented using six types of dental cements.
- A pull-out test measured the load required to dislodge the copings.
Main Results:
- Panavia 21 exhibited the highest mean retention load (36.53 kg).
- Temp Bond NE showed the lowest mean retention load (3.18 kg).
- Significant differences in retention were observed among the tested cements.
Conclusions:
- Cement retention varies significantly when used with titanium abutments.
- Results differ from those obtained with natural teeth, highlighting abutment material influence.
- Clinicians should consider abutment characteristics when selecting cement for implant restorations.
