Title |
Effect of Micro-Etching On The Retention Of Dental Fixed Prosthesis |
Clinical Question |
In a patient receiving a fixed dental prosthesis, does micro-etching improve the retention of a fixed prosthesis as compared to not etching? |
Clinical Bottom Line |
For patients receiving a fixed dental prosthesis, micro-etching, by air-abrasion or intraoral sandblasting, improves the retention of fixed dental prosthesis as compared to not micro-etching in an in in vitro study. |

18618029 | Gurbuz/ 2008 | 60 extracted maxillary molars | In vitro | Key results | The In vitro study indicates a significant increase in retention of all the cements and complete metal crowns when airborne-particle abrasion was implemented (p<0.5).
| 20655101 | Shahin/ 2010 | Extracted human premolars | In vitro | Key results | This in vitro study indicates that air-abrasion significantly increased crown retention for CAD/CAM produced zirconia ceramic crowns (p<0.001). | |

Comments on
The Evidence |
Due to the study type being an in vitro study, the evidence found is relatively weak. There were no competing interests. In order to strengthen the evidence supporting the increased retention when using air-abrasion, clinical studies need to be completed. |
Applicability |
When delivering a fixed dental prosthesis, the intaglio surface of the dental prosthesis can be air-abraded using a intraoral micro-etcher in order to increase the retention for complete metal crowns and CAD/CAM zirconia crowns on premolars and molars. |
