Abstract Purpose To evaluate the survival and success rates of a novel two-piece zirconia implant system restored with screw-retained glass–ceramic crowns over 12 months, including assessment bone levels, soft tissue parameters, patient-reported outcome measures. Methods Twenty-four patients received single implants (CERALOG ® Hexalobe) in healed sites. After 6-month healing period, provisional on PEKK temporary abutments, followed by definitive lithium disilicate (IPS e.max Press) abutments. Clinical radiographic examinations were performed at placement, re-entry, loading, 12-month follow-up, along Results The rate months was 60.9%. Nine lost: two due to lack osseointegration four mobility after three fractures coronal third loading. Surviving showed stable parameters mean probing pocket depths 2.7 ± 0.7 mm months. distance from shoulder first contact decreased 1.9 0.6 loading 1.4 Patients surviving reported high satisfaction scores (4.8 0.4) for function aesthetics. Conclusions restorations unsatisfactory rates. combination ceramic prosthetic may have contributed higher failure observed. As pilot study relatively small sample size, these findings should be confirmed larger multicenter studies validate preliminary results.
