“…On the contrary, Yilmaz et al [29], conducting a load to failure comparison of 5 different titanium abutments, observed that the manufacturer's abutments were the only one not involved in any of the components fracture. The authors suggested that screw fractures experienced by the aftermarket brands may result in further clinical prosthetic complications [29].…”

Purpose Instead of original abutments, compatible abutments are often selected for financial reasons. The present study aimed to evaluate mechanical outcomes, microleakage, and marginal accuracy at the implant-abutment interface of original versus nonoriginal implant abutments. Study Selection Search strategy encompassed literature from 1967 up to March 2017 to identify relevant studies meeting the inclusion criteria. The following electronic databases were consulted: PubMed database of the U.S. National Library of Medicine, Embase (Excerpta Medica dataBASE), and the Grey Literature Database (New York Academy of Medicine Grey Literature Report). Quality assessment of the full-text articles selected was performed. Abutments were classified in original (produced by the same implant manufacturer), nonoriginal certified (produced by a third-party milling center, certified by implant companies), and nonoriginal compatible (produced by a third-party milling center for similar connections). Results A total of 16 articles fulfilled inclusion criteria and quality assessment and were selected for the qualitative analysis. All of the included studies were in vitro research with high or moderate risk of bias and reported data from 653 implant abutments. Original and nonoriginal certified abutments showed better results in terms of mechanical outcomes, microleakage, and marginal accuracy compared to nonoriginal compatible abutments. Conclusions Following the clear warnings coming from the present systematic review, clinical suggestions regarding the effect of a nonoriginal abutment can be drawn. However, in vivo, long-term, randomized controlled trials are needed to provide definitive clinical conclusion about the long-term clinical outcomes of original and nonoriginal abutments.

“…However, in the present study, hybrid abutments were subjected to a fracture-resistance test without crowns to eliminate failures that might occur on crown material and/or the crown/abutment interface, since the study focused on the resistance of hybrid-abutment material. Previous studies investigating titanium and zirconia abutments reported metal deformation of screws and/or abutments and screw fracture after fracture resistance tests [ 42 , 43 , 44 ]. In the present study, failures were detected at the ceramic material and abutment-screw failures were not observed.…”

Polymer-infiltrated ceramic-network (PICN) material is a new type of material used for the hybrid abutments of dental implants. This study aimed to compare flexural strength, bond strengths, and fracture-resistance values of PICN with lithium disilicate ceramic (LDS) and to evaluate the effect of thermocycling on the tested parameters. Twenty specimens were fabricated using computer-aided design and manufacturing (CAD-CAM) technology for each material according to three-point bending (n = 10), microshear bond strength (µSBS), and a fracture-resistance test (hybrid abutment, n = 10). All specimens of each test group were divided into two subgroups, thermocycled or nonthermocycled. Hybrid abutments were cemented on titanium insert bases and then fixed on implants to compare fracture resistance. Failure loads were recorded for each test and data were statistically analyzed. Thermocycling decreased bond strength to the resin luting agent and the fracture-resistance values of both materials (p < 0.001), whereas flexural-strength values were not affected. LDS ceramic showed significantly higher flexural strength, bond strength, and fracture-resistance values than PICN material (p < 0.001). Within the limitations of this study, LDS may be a preferable hybrid-abutment material to PICN in terms of mechanical and bonding properties.

“…Some of them offer similar implant connection design, being possible to restore implants from one company with non-original prosthetic components but with unknown consequences for the longevity of the prostheses. Some studies have investigated the effect of interchanging components of different brands and they have found discrepancies with the original design [2][3][4][5][6][7]. Variations in the internal tolerances or design of the abutments can lead to modi cations in the mechanical behaviour of the restoration.…”

“…Variations in the internal tolerances or design of the abutments can lead to modi cations in the mechanical behaviour of the restoration. It can result in stress on the prosthetic screw leading to screw loosening or screw failure [3]. Moreover, the cyclic loading could also affect the formation of microgaps at the implant-abutment interface resulting in large differences in the overall contact areas [8,9].…”

“…Or what is the same, which is the load limit to which a specimen could survive for an in nite life. From the restorative point of view, this information is much more useful than the conclusions that could be drawn from a static load test [2,3,15,16] where the specimens will then be subjected to a single-load test until fracture but, as we have seen before, this situation is far from reality and the conclusions obtained should be taken with caution.…”

Background: Restoring implants with not original abutment-implant connection are widely used by clinicians. Due to the current scarcity of in-vitro studies about compatible abutments and lack of relevant clinical studies, long-term fatigue performance of non-original abutments should be analyzed. The aim of this research was to assess the internal accuracy and the cyclic fatigue life after artificial aging of three implant-abutment configurations restored with one original and two compatible non-original “cast-to” gold abutments.Materials and Methods: Forty-eight original internal hexagon connection implants were connected to three different brands of abutments (n= 16 each): one original to the implant system and two non-originals. Internal accuracy and the percentage of surface with tight contact were assessed under Scanning Electron Microscope (SEM) in twelve cross-sectioned samples at three different areas (platform, internal and screw). To evaluate the fatigue mechanical behaviour under cyclic load, samples were loaded according to the ISO Norm 14801 in a universal testing machine at 2 Hz in air. Previously, samples were aged by thermocycling with 10,000 cycles at 5 °C and 55 °C in artificial saliva. Results: Original abutments presented the best accuracy and highest percentage of tight contact in the internal areas. Meanwhile, original abutments showed the lower cyclic fatigue strength degradation and the long-term success. Conclusions: Occlusal loads are transferred more homogenously through the system when original abutments are used because the better fit between the different internal components. This fact provides the highest fatigue resistance for all the restorations studied.
