Clinically, patients performed an adequate OH, and tissues were kept healthy. Probing depth showed a slightly lower value at baseline compared to any follow\u2010up examination (2.26 [0.94] at baseline vs. 2.53 [0.66]\u00a0mm at 12 months). ES, GZP, and the thickness of the peri\u2010implant gingiva improved throughout the course of the study. Radiographically, average marginal bone level (MBL) was 0.40 (0.40)\u00a0mm after 1\u2010year follow\u2010up with no differences in average MBL at all time points. Technically, after 1 year of clinical function, neither abutment fracture nor any other serious complications occurred. Hence, prosthetic reconstruction survival rate was 100%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Clinical outcomes of single\u2010tooth implant restorations using internally connected, screw\u2010retained, computer\u2010aided design and computer\u2010aided manufacturing monolithic zirconia abutments can be considered a reliable treatment alternative after 1\u2010year clinical observation.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jopr.13674","type":"journal-article","created":{"date-parts":[[2023,3,8]],"date-time":"2023-03-08T06:27:36Z","timestamp":1678256856000},"page":"679-688","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Screw\u2010retained internal connection zirconia CAD\u2013CAM abutments in single implant reconstructions: Results of a 1\u2010year prospective case series study"],"prefix":"10.1111","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5264-3708","authenticated-orcid":false,"given":"Rafael","family":"del Castillo","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Eastman Institute for Oral Health University of Rochester  Rochester New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lourdes","family":"Guti\u00e9rrez\u2010Garrido","sequence":"additional","affiliation":[{"name":"PhD Program in Clinical Medicine and Public Health University of Granada  Granada Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6222-1341","authenticated-orcid":false,"given":"Miguel","family":"Padial\u2010Molina","sequence":"additional","affiliation":[{"name":"Department of Oral Surgery and Implant Dentistry, School of Dentistry University of Granada  Granada Spain"},{"name":"Instituto de Investigaci\u00f3n Biosanitaria.
