“We are going to need a more accurate impression”. If you have ever received that message from your dental lab, you probably cringed. Getting the patient back in for a new impression causes you, the dentist, valuable chair time and inconveniences your patient. An accurate dental impression is critical to assure good appliance fit and minimal chair-side adjustment. Even the most experienced practitioner can encounter difficulties when making an impression.
Making an accurate impression is the first and most important step in creating superior prosthetic restorations for your patients.
A good impression will have the following:
- Uniform, homogeneous mix of materials
- Tray is sufficiently filled with impression material
- Thoroughly applied tray adhesive
- Rigid, sturdy impression tray
- No voids or pulls on margin detail
- Detailed margins with no tears or rough surfaces
- No tray show-through of the impression material
- Good blend between heavy body and light body materials
- Strong bond between impression material and tray
- No tooth contact with the tray
As a dental lab, Image Dental Arts is committed to assisting dentists in saving chair time and delivering superior restorations to your patients.
In our mission to provide educational and helpful articles for dentists, we discovered this wonderful trouble shooting e-book from 3M, Making Better Impressions. In this e-book, common issues with solutions are outlined such as: lack of impression detail, tearing at the margin, voids on the margin, and other problems. Access the guide here.
