Group-specific cumulative prosthetic survival was qualitatively and quantitively compared using Kaplan–Meier, generalized linear mixed models and univariate cox proportional hazard analyses.

This follow-up study collected and examined the 5-year data to answer the main question: What are the survival and the success rates of custom-made ZrO&lt;sub&gt;2&lt;/sub&gt; implants in the maxillary premolar region after 5 years?&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Material and Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Of the 31 included patients in this prospective 5-year follow-up single-arm clinical trial, 30 received a custom-made ZrO&lt;sub&gt;2&lt;/sub&gt; implant to replace a missing single maxillary premolar, which was subsequently restored with a lithium disilicate crown. Parameters regarding clinical performance, marginal bone-level (MBL) changes, and patient-related outcome measures (PROMs) were assessed preoperatively, at the baseline, as well as 1 and 5 years after crown placement. Chances of survival and success of the implant were calculated and displayed using Kaplan–Meier statistics. Kaplan–Meier survival analysis was also performed with stratification based on the variables “manipulation of the implant prior to impression taking” and “occlusal scheme” and compared using log-rank tests. Bone-level moderation in time was compared using a paired samples &lt;i&gt;t&lt;/i&gt;-test. Patient's expectations and satisfaction after 5 years were compared as a measure of fulfilled expectations, using a Wilcoxon signed-rank test. Performance of the implant-supported crowns was evaluated using validated criteria.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Survival and success probabilities after 5 years were, respectively, 75.8% (95% CI [60.0%; 91.0%]) and 71.0% (95% CI [54.0%; 88.0%]) for the custom-made ZV3 implants.
