An interventional study of Zirconia crowns (Prettau®) and lithium disilicate crowns (IPSe.max®) in Sleep Bruxism and Monolithic Ceramic Fixed Dental Prosthesis (Single Crowns), sponsored by Heidelberg University. Completed at 1 site in Germany. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-05-16.
Sponsored by Heidelberg University · Not applicable, Interventional, and Treatment
The aim of the study is to evaluate the complication rate of 2 types of all-ceramic crowns in patients with or without bruxism.
63 studies on the registry are indexed under Sleep Bruxism; 10 are open to participants now.
This study's enrollment of 109 is above the median of 40 across 41 interventional studies indexed under Sleep Bruxism.

Success of all-ceramic crowns as determined by complication rate
In this study, a complication is defined as any event happening at the study crown or the supporting tooth that requires a clinical intervention.
