Objective
<p>Objective of this study was to evaluate the incidence of complications in dental implants and abutment teeth used for combined tooth‐implant‐ and solely implant‐supported double crown‐retained removable dental prostheses (<hi rend="fc">RDP</hi>s).</p>
Material and methods
<p>Patients were selected from a prospective clinical study. Seventy‐three <hi rend="fc">RDP</hi>s retained by 234 implants and 107 abutment teeth were placed in 39 men and 22 women with a mean age of 65 years. Forty‐five <hi rend="fc">RDP</hi>s were located in the maxilla and 28 in the mandible. Thirty‐four <hi rend="fc">RDP</hi>s were solely implant‐supported and 39 were combined tooth‐implant‐supported. Kaplan–Meier analysis was used to estimate success defined as survival without severe abutment‐related complications, and Cox regression was used to isolate the most relevant prognostic risk factors.</p>
Results
<p>After a median observation period of 2.7 years for the <hi rend="fc">RDP</hi>s, six implants failed and eleven implants were diagnosed with peri‐implantitis. Four abutment teeth were extracted, and three abutment teeth showed severe complications requiring extended interventions. For both abutment teeth and implants, Kaplan–Meier analyses revealed a 5‐year probability of success of 85% for solely implant‐supported <hi rend="fc">RDP</hi>s and 92% for combined tooth‐implant‐supported <hi rend="fc">RDP</hi>s. Multiple Cox regression identified <hi rend="fc">RDP</hi> location (<hi rend="italic">P </hi>=<hi rend="italic"> </hi>0.01), age (<hi rend="italic">P </hi>=<hi rend="italic"> </hi>0.01), and gender (<hi rend="italic">P </hi>=<hi rend="italic"> </hi>0.04) as prognostic risk factors for severe implant‐related complications. Solely implant‐supported <hi rend="fc">RPD</hi>s showed a poorer prognosis, but the risk difference did not reach statistical significance.</p>
Conclusions
<p>Preliminary data suggest that the combination of teeth and implants to support double crown‐retained <hi rend="fc">RDP</hi>s may result in a prognostic advantage. The present findings should be validated in independent studies.</p></abstract><textClass><keywords><term xml:id="clr12197-kwd-0001">complication</term><term xml:id="clr12197-kwd-0002">dental implants</term><term xml:id="clr12197-kwd-0003">prognosis</term><term xml:id="clr12197-kwd-0004">removable dental prosthesis</term><term xml:id="clr12197-kwd-0005">telescoping double crown</term></keywords><keywords rend="articleCategory"><term>Original Article</term></keywords><keywords rend="tocHeading1"><term>Original Articles</term></keywords></textClass><langUsage><language ident="en"></language></langUsage></profileDesc></teiHeader></istex:fulltextTEI></fulltext><metadata><istex:metadataXml wicri:clean="Wiley, elements deleted: body"><istex:xmlDeclaration>version="1.0" encoding="UTF-8" standalone="yes"</istex:xmlDeclaration><istex:document><component type="serialArticle" version="2.0" xml:id="clr12197" xml:lang="en"><header><publicationMeta level="product"><doi origin="wiley" registered="yes">10.1111/(ISSN)1600-0501</doi><issn type="print">0905-7161</issn><issn type="electronic">1600-0501</issn><idGroup><id type="product" value="CLR"></id></idGroup><titleGroup><title sort="CLINICAL ORAL IMPLANTS RESEARCH" type="main">Clinical Oral Implants Research</title><title type="short">Clin.

Seventy‐three RDPs retained by 234 implants and 107 abutment teeth were placed in 39 men and 22 women with a mean age of 65 years. Forty‐five RDPs were located in the maxilla and 28 in the mandible. Thirty‐four RDPs were solely implant‐supported and 39 were combined tooth‐implant‐supported. Kaplan–Meier analysis was used to estimate success defined as survival without severe abutment‐related complications, and Cox regression was used to isolate the most relevant prognostic risk factors.</abstract><abstract>After a median observation period of 2.7 years for the RDPs, six implants failed and eleven implants were diagnosed with peri‐implantitis. Four abutment teeth were extracted, and three abutment teeth showed severe complications requiring extended interventions. For both abutment teeth and implants, Kaplan–Meier analyses revealed a 5‐year probability of success of 85% for solely implant‐supported RDPs and 92% for combined tooth‐implant‐supported RDPs. Multiple Cox regression identified RDP location (P = 0.01), age (P = 0.01), and gender (P = 0.04) as prognostic risk factors for severe implant‐related complications. Solely implant‐supported RPDs showed a poorer prognosis, but the risk difference did not reach statistical significance.</abstract><abstract>Preliminary data suggest that the combination of teeth and implants to support double crown‐retained RDPs may result in a prognostic advantage.
