Mean age was 67 years, mean follow-up time was 3.4 years. 27.75% of prostheses were borne on one abutment tooth, 40.97% on two and 31.28% on three abutment teeth. In 60.4% percent of cases, copings were cast from a precious alloy. The 5-year survival rate for cover-dentures was 64.5%. The most common complication (36.6%) was decementation of a coping. In 30.9% of cases, one or more abutment teeth fractured and in 28.7% of cases one or more abutment teeth were lost. Most common need for maintenance was the removal of pressure points in the prosthesis. In 29.5% of cases, a relining of the cover-dentures was necessary.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A cover-denture prosthesis is a suitable therapeutical option for patients with few remaining teeth. The survival rate is comparable to that of other double crown retained removable partial dentures and occurring complications are manageable. Cover-denture prostheses represent an adequate alternative to complete extraction and can be recommended in clinical practice.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s13005-026-00619-9","type":"journal-article","created":{"date-parts":[[2026,4,21]],"date-time":"2026-04-21T14:29:59Z","timestamp":1776781799000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Survival rate and need for maintenance of cover-denture prostheses borne on three or less abutment teeth: ten-year results"],"prefix":"10.1186","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-7612-3148","authenticated-orcid":false,"given":"Laurentia","family":"Schuster","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali-Reza","family":"Ketabi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Till","family":"Dammaschke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans-Christoph","family":"Lauer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,4,21]]},"reference":[{"key":"619_CR1","doi-asserted-by":"publisher","first-page":"20","DOI":"10.1111\/j.1600-0501.2007.01435.x","volume":"18","author":"NU Zitzmann","year":"2007","unstructured":"Zitzmann NU, Hagmann E, Weiger R.
