The objectives of the present study are to analyze and to compare the survival rates and possible biological and technical complications arising from the use of composite-ceramic posterior implant-supported crowns with those obtained when using their counterparts prepared using monolithic zirconia restorations. The null hypothesis is that no differences would be found between the parameters studied for each type of restoration.
