Fig.4: immediately postop (I: implant).
Fig.7: 3 months postop.
A high-noble crown is cemented 4 months postop. The mesial crest has formed cortical bone nearly 2 years post cementation (Fig.8 ^ (25 months postop)). The 4.5 mm 10 degree abutment (Ketac cementation) becomes loose 5 years 7 months. The crown is removed; a 5x5 mm straight abutment is cemented with Calibra. PA is taken when a new high noble crown is cemented with Calibra (Fig.13). There will be no more free hand implant placement.
