By masking the implants with artificial gingiva, 2 other distinct definitive casts were obtained for 2 subgroups: the 4–24 subgroup, which included 4 implants (right first premolar, right lateral incisor, left lateral incisor, and left first premolar) and the 4–26 subgroup, which also included 4 implants (right first molar, right lateral incisor, left lateral incisor, and left first molar). Three methods were used to record implant location in these 3 subgroups: conventional impression making using the open-tray splinted technique (group CNV), intraoral scanning with the use of conventional scan bodies (group IOS-C), and intraoral scanning using newly modified scan bodies (group IOS-M). To assess accuracy, the best-fit algorithm was used, and root mean square (RMS) values were calculated. Descriptive statistics, including the median, interquartile range, and minimum and maximum values, were used to summarize the variables. Accuracy among different groups was compared, and the influence of the number of implants and the scan distance on the accuracy of group IOS-M was investigated.

A restorative material used for occlusal veneers should have a smooth surface, adequate wear resistance, and low abrasiveness to the antagonists, as total wear of occlusal veneers and their antagonists determines the stability of the reestablished VDO. Studies on roughness, wear, and abrasiveness of occlusal veneers are scarce.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Purpose&lt;/h3&gt;&lt;div&gt;The purpose of this in vitro study was to assess the surface roughness, wear, and abrasiveness of printed and milled occlusal veneers after thermomechanical aging against natural cusps and restorative materials.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Material and methods&lt;/h3&gt;&lt;div&gt;Forty-eight extracted mandibular first molars were prepared for occlusal veneers and scanned with an intraoral scanner. The scans were exported to a computer-aided design program to design the occlusal veneers in 3 groups (n=16) according to the restorative material: group IP: milled lithium disilicate; group EN: milled hybrid ceramic (Vita Enamic), group VA: printed hybrid ceramic (Varseosmile Crown plus). The occlusal veneers in each group were bonded to their corresponding abutments and subjected to 250 000 mechanical cycles and a simultaneous 1000 thermal cycles in a mastication simulator. During thermomechanical aging, half of the specimens of each study group (n=8) were opposed by natural cusps (antagonist C) and the other half by antagonist cusps fabricated from the same restorative material as the occlusal veneers (antagonist R). The wear of the occlusal veneers and their antagonists was assessed with a 3-dimensional processing software program. The surface roughness of the veneers was assessed with a contact profilometer. The results were statistically analyzed with a 2-way ANOVA followed by the post hoc Tukey HSD test (α=.05).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;The 2-way ANOVA indicated a significant effect for the material and the antagonist on surface roughness, wear, and abrasiveness (&lt;em&gt;P&lt;/em&gt;&lt;.05). When opposed by antagonist C, VA showed significantly higher surface roughness than IP and EN (&lt;em&gt;P&lt;/em&gt;&lt;.001). VA had significantly higher surface wear followed by EN and IP (&lt;em&gt;P&lt;/em&gt;&lt;.001). IP caused significantly higher wear to antagonist C than EN and VA (&lt;em&gt;P&lt;/em&gt;&lt;.001). In addition, IP had significantly higher total wear (combined wear of veneers and their antagonists) followed by VA and EN (&lt;em&gt;P&lt;/em&gt;&lt;.001). When opposed by antagonist R, no significant difference was found among the 3 materials for surface roughness (&lt;em&gt;P&lt;/em&gt;=.08), material wear (&lt;em&gt;P&lt;/em&gt;=.12), opposing wear (&lt;em&gt;P&lt;/em&gt;=.11), or total wear (&lt;em&gt;P&lt;/em&gt;=.11).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;div&gt;Both material and antagonist had a significant effect on surface roughness and occlusal stability when occlusal veneers were fabricated to restore VDO.
