i500 Case Study: Onlay After Endo and Reconstruction

Share this with a friend:


Dr. José Gabriel Martínez is an Associate Professor at the Universitat Internacional de Catalunya (The International University of Catalonia) in Barcelona Spain. His practice is exclusively dedicated to restorative work, prosthodontics, and aesthetics. Dr José shares with us a case study of an onlay after endo and reconstruction with the Medit i500 intraoral scanner. 


Before I begin, I’d like to give a brief summary of the case. This case was done in collaboration with Ibiza Dental Lab by Carlos OrtízAt my practice, we always scan every patient during their first visit. For this case, we cloned the case, erased the working area, and re-scanned. We always delimit the margin line of our restorations, allowing the lab to have precise info about the prep by the moment they start the design. In addition, we also communicate the rehabilitation space to the lab in order to be sure that everything works perfectly. Let’s go over the case study now. 




This is the initial situation after endo treatment and preparation. We are now ready to scan.

Adding the margin line. We always try to draw the margin line to ensure that the lab will take reference from our prep work. This is because as a clinician, we know that the person preparing the case will know the exact boundaries and will be able to better convey that information to the lab for a better end result.

We then selected the prep area. The objective is to measure the interocclusal distance to know how much rehabilitation space we have to work with.

Here, we measure the interocclusal distance.

This feature allows us to have an exact measurement of the distance between teeth points.  

This is very important for us to select the restorative material, as well as to check if we need additional prep work in order to have sufficient space. 

Our lab then designed an onlay restoration, done in exocad.

We usually specify and request for the restorative material which we decide on depending on the situation. In this case, we also printed a model from our exported .stl file from the case. The restorative material used was Vita enamic multi.

Finally, a protocol was performed with Vita Adiva dual cure system. The cement color used was A2.

Material: Vita Enamic Multi 
Cement: Vita Adiva dual cure 
Scanner: Medit i500
