DOI: 10.11607/ijp.3976, PubMed ID (PMID): 25588171Pages 37-39, Language: EnglishMenini, Maria / Pera, Francesco / Migliorati, Marco / Pesce, Paolo / Pera, PaoloPurpose: This in vitro study evaluated the adhesive strength of a technique to lute implant cylinders to metal frameworks in implant-supported prostheses and ensure a good passive fit.
Materials and Methods: Different height samples were tested: In group 1, implant cylinders were 5 mm long; in group 2, they were 10 mm long. A universal testing machine (Instron) was used to perform pullout tests.
Results: The luting technique provided enough adhesive strength for clinical use with greater adhesive strength in group 2 (mean pull-out strength: 2.85 kN in group 1 versus 3.79 kN in group 2).
Conclusions: The luting technique provides enough adhesive strength for clinical use. Moreover, specimens with a larger surface for adhesion demonstrated higher adhesive strength compared with shorter specimens.
