dc.description.abstract | Introduction: Different implant–abutment connections have been developed to reduce
mechanical and biological failure. The most frequent complications are loss of preload, screw loosening,
abutment or implant fracture, deformations at the different interfaces, and bacterial microleakage.
Aim: To review the evidence indicating whether the implant–abutment connection type is significant
regarding the following issues: (1) maintenance of the preload in static and dynamic in vitro
studies; (2) assessment of possible deformations at the implant–abutment interfaces, after repeated
application of the tightening torque; (3) evaluation of the sealing capability of different implant
connections against microleakage. Materials and Methods: In June 2020, an electronic literature search
was performed in Medline, EBSCO host, and PubMed databases. The search was focused on the
ability of different implant connections to maintain preload, resist deformation after tightening
and retightening, and prevent microleakage. The related titles and abstracts available in English
were screened, and the articles that fulfilled the inclusion criteria were selected for full-text reading.
Results: The literature search conducted for this review initially resulted in 68 articles, among which
19 articles and 1 systematic review fulfilled the criteria for inclusion. The studies were divided
according to the three proposed objectives, with some studies falling into more than one category
(maintenance of preload, surface abutment–implant deformation, and resistance to microleakage).
Conclusions: Conical abutment appears to result in fewer mechanical complications, such as screw
loosening or fractures, and higher torque preservation. After SEM evaluation, damage was observed
in the threads of the abutment screws, before and after loading in internal and external connections.
Internal hexagon implants and predominantly internal conical (Morse taper) implants showed less
microleakage in dynamic loading conditions. We suggest further studies to guarantee excellence in
methodological quality. | es |
