Clinically, patients performed adequate oral hygiene, and tissues were kept healthy as determined by plaque index (PI) and oral hygiene index (OHI). The esthetic performance of the restorations revealed an increase in mucosal thickness from 3.2 (0.9) mm after 1 year to 3.3 (1.1) mm after 5 years, and a reduction in the gingival zenith position from 7.9 (1.5) mm after 1 year to 7.7 (1.5) mm at the 5\u2010year recall examination. The prosthetic survival rate after 5 years was 78.9%, as 4 abutments fractured at different time points during the study. All abutment fractures occurred in the mandible, at the level of the second premolars and first molars.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>After 5 years clinical function, Atlantis one\u2010piece, screw\u2010retained, internally connected CAD\u2010CAM veneered zirconia implant\u2010supported single crowns resulted in a relatively low survival rate, mainly associated with posterior single implant\u2010supported reconstructions. However, due to the fact that the present clinical investigation used only one abutment design and reconstruction type, extrapolation of data to different implant systems, abutment designs, and reconstruction types must be cautious.<\/jats:p>\n
