Full ceramic single crowns were placed after 16 weeks healing on PEKK abutments, and after one year of loading the success rate was 100%. Conclusion 1. CERALOG implants are a trendsetter in terms of ceramic dental implant development and clinical use. 2. The reversible screw-retained abutments are just one of the key benefits of the CERALOG Hexalobe implants. 3. The primary stability of CERALOG implants is comparable to that of titanium implants. Clinical case A 38-year old female patient presented with a vertical longitudinally fractured root of the left first upper premolar. The tooth was extracted four months prior to placing a CERALOG Hexalobe implant (L 10 mm). After a healing period of 4 months, the implant was restored with a screw-retained zirconium oxide crown which had been previously bonded onto a PEKK abutment in the laboratory (Figs. 6-11).
