What is it about?

Tooth wear in bruxing patients often results in a need for treatment with composite restorations and/ or with occlusal splint as a protective means .However, the wear between these opposing materials has not been investigated yet. In this in- vitro study the wear of known composites are tested against different PMMA's commonly used for the fabrication of occlusal splints.

Why is it important?

Now a days there's more materials and manufacturing options for occlusal splints .Our findings show that conventional splints made of PMMA and milled splints made of PMMA are wearing faster than other materials as the printed PMMA splints. This is important when consider that we would like to protect as much as possible the restorations done on bruxing patients or just to protect their own dentition. At this moment we have more splint options according to the patient needs and according to the type of patient we are treating.


Occlusal splint is a very common treatment for bruxing patients or for patients that experiences TMD complains. Up to now we just prescribe splints without really looking at the composition and or at the manufacturing process of splints. With new improvements of the digital era is very important to look at the type of splints in terms of manufacturing and to whom we are going to prescribe. The digital era brings great improvements for the daily practice. But as practitioner we are not really looking at the splints wear i.e. Very often splints are just prescribe without looking at the patient type. It is not the same to prescribe a splints to a bruxing patient that is grinding and clenching very often at the night than to a TMD patient. Sometimes the consequences between these two type of patients might be different. Therefore now we can choose which splints might last longer and wear less according to the patient indication. I hope you find this article thought-provoking .
