AbstractObjectivesThe aim of the present study was to assess the shock absorbing capacity of implant‐supported restorations (CAD/CAMcomposite resin or zirconia abutment with composite resin or porcelain crown/onlay) and a simulated natural tooth complex using the Periometer®.Material and methodsOne hundred and twenty Morse taper implants (Titamax CM 11 mm) were mounted on bone‐simulating acrylic resin base and restored withCAD/CAMzirconia (60) and metal composite resin Paradigm MZ100 (60) abutments. Using CEREC3, standardized onlays (60) and crowns (60) were designed and milled in ceramic (Paradigm C) or composite resin (Paradigm MZ100) to simulate a maxillary premolar. All restorations were luted with a preheated light curing composite resin (Filtek Z100). Fifteen extracted human upper premolars were mounted with a simulatedPDLand used as control group. The Periometer®, a new handheld percussion probe that measures the energy loss coefficient (LC) for both natural teeth and implant‐supported structures, was positioned perpendicularly to the buccal surface of each restoration. Three measurements of theLCwere collected for each specimen. The effect of each variable (abutment material, restoration material, and restoration design) on theLCwas explored using multiple regression analysis.ResultsDifferences inLCbetween the abutment material (zirconia/Paradigm MZ100), the restoration material (Paradigm C/Paradigm MZ100) and the restoration design (onlay/crown) were recorded. The averageLCof zirconia and metal composite resin abutments ranged from 0.040 to 0.053 and 0.059 to 0.068, respectively. Zirconia abutments restored with composite resin restorations (LC0.051–0.053) had the closestLCvalue when compared with teeth with simulatedPDL(0.049).ConclusionComposite resin onlays/crowns bonded to zirconia implant abutments presented similar dynamic response to load (damping behavior) when compared to teeth with a simulatedPDL.
