“…The implant connection has not been demonstrated to prevent bacterial contamination [1, 2]. In contrast, the different torques applied to the abutment-implant system condition the bacterial leakage at the implant interface, with no microleakage observed at 20 and 30 N compared to <10 and 10 N [3]. In reality, the microgap acts as a bacterial reservoir that may trigger an inflammatory host response in the peri-implant soft tissues and bone [1, 2, 4].…”

“…More importantly, the gap between the implant and the abutment is a factor in chronic inflammatory infiltration, as it allows the passage of acids, enzymes, bacteria, and/or their metabolic products [5]. In fact, since the IAI is located near the alveolar bone crest, bacterial colonization of the gap has been implicated in the physiological biologic width establishment that occurs during the first 6 months after loading [3, 6]. Interestingly, the 8th consensus of the European Federation of Periodontology [7], as well as the Position Paper of the American Academy of Periodontology [8], agreed upon the likely initial bone remodeling after implant restoration to accommodate biologic width.…”

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.

“…The implant-abutment sealing promoted by the precision of adaptation of implant components is extremely important because it works as a barrier to the penetration of microorganisms residing in the oral cavity, preventing peri-implant pocket formation and promoting bone maintenance in the region (Maeda, et al 2006;Larrucea, et al, 2018;Canullo, Camacho, Tallarico, Meloni, Xhanari, 2017).…”

Objectives: To evaluate in vitro the micromorphological differences of the prosthetic implant-abutment interface in two screw implant systems and a friction one.Materials and methods: Two screw implants (Group 1- Crossfit Internal Connection, Group 2- Tapered Internal Connection), a compressed friction implant (Group 3 - Frictional Connection), and their corresponding prosthetic components were used. The implants were individually fixed in an acrylic resin cylinder and the abutments were positioned with the torque recommended by the manufacturer and taken into a SkyScan 1173 microtomograph. In each implant-abutment image, the regions of interest evaluated were cervical area, abutment area, screw area, and abutment and screw area (G1-G2). In group 3, the cervical and abutment areas were measured. Statistical analysis was performed with ANOVA, Robust ANOVA, and Post Hoc Tukey’s test.Results: In the cervical region, only the samples from group 2 presented maladaptation (12.5 ± 7.0 µm). In the abutment area, the samples from groups 1 (159.6 ± 6.2 µm) and 2 (149.9 ± 9.1 µm) were statistically similar. In the screw area and the abutment and screw area, group 1 had a larger contact surface compared to group 2 but they were statistically similar.Conclusion: The samples from groups 1 and 3 did not present micro-spaces in the cervical third. Nevertheless, the samples from group 2 presented a mismatch in this region but within the acceptable limits found in the literature.

“…9,10 A mixture of this debris with microorganisms in saliva may enter the tissue surrounding the implant, which results in microleakages at the IAI. 11 Various studies have reported the roles of wear debris in peri-implantitis, [12][13][14] but the mechanisms underlying the metal wear debris generated by micromotions at the IAI have not yet been fully elucidated.…”

Fretting damage at the dental implant-abutment interface (IAI) is a critical factor of dental implant failure, and it has been investigated using fatigue cycle (FC) loading tests. For the first time, we applied chewing cycle (CC) loading onto the IAI to simulate masticatory movements. It was found that more serious furrow wear was induced by the sliding forces present under CC loading. Furthermore, four types of metal wear debris and a markedly higher torque loss rate were observed after undergoing both cyclic loadings. Such debris can aggravate the resulting fretting damage, and an increased amount of largegrain wear debris was generated under CC loading. Therefore, CC loading can be an effective approach for exploring the fretting damage at the IAI to improve implant-supported prostheses.
