“…Recent publications on the theme of nonoriginal implant abutments also seem to point in the direction of more favorable results for original components (Alonso‐Pérez et al, 2022 ; Berberi et al, 2022 ; Jarman et al, 2017 ). However, much of that research was performed, at least in part, on zirconia abutments.…”

“…Most revolve around the degree of misfit. It is suggested that more misfit between implant and abutment leads to a higher degree of complications, such as screw loosening or screw fracture, especially after cyclic loading and fatigue testing (Alonso‐Pérez et al, 2022 ; Berberi et al, 2022 ; Fokas et al, 2019 ; Karl & Irastorza‐Landa, 2018 ; Karl & Taylor, 2016 ). This would entail that testing nonoriginal components from other suppliers, especially suppliers with less stringent quality control and design specifications, could lead to a larger distinction between original and nonoriginal components.…”

ObjectivesThe study aimed to assess the impact on the mechanical strength and failure patterns of implant‐abutment complexes of choosing different abutment types, designs and manufacturers, aiding in selecting the optimal restorative solution. Stock and custom abutments from original and aftermarket suppliers were subjected to thermomechanical aging.Material and MethodsStock and custom abutments from the implant manufacturer (original) and a aftermarket supplier (nonoriginal) were connected to identical implants with internal connection. Custom abutments were designed in a typical molar and premolar design, manufactured using the workflow from the respective suppliers. A total of 90 implants (4 mm diameter, 3.4 mm platform, 13 mm length) equally divided across 6 groups (three designs, two manufacturers) underwent thermo‐mechanical aging according to three different regimes, simulating five (n = 30) or 10 years (n = 30) of clinical function, or unaged control (n = 30). Subsequently, all samples were tested to failure.ResultsDuring aging, no failures occurred. The mean strength at failure was 1009N ± 171, showing significant differences between original and nonoriginal abutments overall (−230N ± 27.1, p < .001), and within each abutment type (p = .000), favoring original abutments. Aging did not significantly affect the failure load, while the type of abutment and manufacturer did, favoring original and custom‐designed abutments. The most common failure was implant bending or deformation, significantly differing between original and nonoriginal abutments and screws. All failure tests resulted in clinically unsalvageable implants and abutments.ConclusionsWithin the limitations of this study, original abutments exhibited a higher mechanical strength compared to the nonoriginal alternative, regardless of the amount of simulated clinical use. Similarly, custom abutments showed higher mechanical strength compared to stock abutments. However, mechanical strength in all abutments tested was higher than average chewing forces reported in literature, thus components tested in this study can be expected to perform equally well in clinical situations without excessive force.

“…47 The dimensions and geometry of such components may not be specifically designed to match the specifications of the original implant system. This can lead to compatibility issues, such as improper fit, 48,49,50,51,52 inadequate sealing, 53 rotational misfit, 54 leakage 53 and/or compromised stability. Poor compatibility can, in the longer-term, result in mechanical complications, including component failure, screw loosening, 55 or even implant fracture and loss.…”

Current research has identified features of the prosthetic design with potential to significantly impact the long-term health of peri-implant tissues, while the choice of prosthetic components is also shown to be critical in an effort to reduce long-term complications of implant therapy. Overcontouring of the prosthesis emergence profile has been associated with marginal bone loss, recession and peri-implantitis, while the mucosal emergence angle is shown to have a strong association with peri-implant tissue inflammation. Further elements of interest include convexity/ concavity of the restoration, the prosthetic connection and the different geometric configurations of junctions, as well as the peri-implant tissue dimensions. With regards to implant components, the choice between original and thirdparty-manufactured components might come with implications, as differences in material and microgeometry might impact precision of fit and overall performance, potentially leading to complications. Scrutiny of the specifications and manufacturing is essential when third-party-manufactured components are considered.The aim of this narrative review was to summarise the current evidence with regards to the restorative features of the implant prosthesis and also the selection of prosthetic components which can have implications for the longterm success of the implant therapy. Furthermore, the review aimed at interpretating current scientific evidence into meaningful strategies and recommendations to implement in clinical practice of implant dentistry.

Position and posture measurement of stereo probes for dental implants with a four-camera vision system

.The fixed denture supported by multiple implants can effectively improve the retention and stability of traditional complete dentures, and greatly improve the masticatory ability and life quality of patients, which has been proven to be a reliable treatment method. However, how to accurately obtain the position and posture of multiple implants while the patient feels comfortable is still one of the main clinical difficulties. We design a four-camera system and propose its corresponding method, which accurately measures the position and posture of stereo probes (note that the stereo probes are finely screwed on the implants, i.e., the coordinate systems of the implants are transferred to the stereo probes). In the calibration, a ChArUco calibration board is introduced and the calibration parameters are derived utilizing the proposed three-stage calibration strategy. In the measurement, the stereo probes are screwed on the implants and captured by the four-camera system. Through Canny/Devernay method, the gauge points on the surface of the stereo probe can be solved. Subsequently, the decoding of the gauge points and stereo probes is achieved by the implementation of the proposed matching and decoding strategy. In addition, to achieve higher accuracy, a refinement approach under multiview for the position and posture of stereo probes is established. The result of the experiments verifies that our system and method have higher accuracy and effectiveness (note that the distance error between the two stereo probes is about 19 μm), which is entirely satisfactory for the application of digital implant impressions.
