Methodology: Qualitative and retrospective systematic bibliographic review, an electronic search was carried out through PubMed, Google Scholar and Elsevier using the terms "adhesive bridge", "minimally invasive", "zirconia" and "E.Max".

Results: There is a wide variety of materials for the manufacture of Maryland adhesive bridges such as: Zirconia, which has excellent physical and mechanical properties; Lithium Disilicate with a highly aesthetic property due to its translucency, porcelain metal with its various favorable characteristics and PMMA with its simplicity in manufacture.

Conclusions: There are different situations for which the Maryland bridge is indicated, mainly to maintain some space after orthodontic treatment. It is important to have previous knowledge of the protocol indicated for the adhesion of the adhesive bridge and its materials.
