Most important are the re- duction of BIC and increase in the time tissue needs to overcome obstacles, if possible. The microscopy findingsconfirmedourinitialsuspicions(seePartIof thisseries).Theydeterminedanumberoffactorsthat influence tissue response and osseointegration. The findings were as follows: – blasting media residue – surface defects – lack of surface treatment – lack of thread precision – production procedure residue – metal cuttings 22 I implants3_2015 No Region Surface irregular roughness irregular surface, partly no surface treatment blast defects blast media residuals, massiv metal cuttings undefined structural defects compromised tissue ongrowth dokumentation fault 1 16 machined collar yes no yes yes, massiv – yes apical third, only thread flanks no 2 45 machined collar yes no yes yes, massiv – yes apical third, only thread flanks no 3 16 textured collar yes no yes yes, massiv – no crestal third no 4 44 textured collar yes no yes yes, massiv – no crestal third no 5 33 textured collar manufacturer manufacturer manufacturer manufacturer manufac- turer manufacturer manufacturer manufacturer 6 15 bone level zikronia blasted no yes yes yes, massiv – yes barely, only thread flanks no 7 43 machined collar yes no yes yes, massiv – no crestal third no 8 15 bone level zikronia blasted manufacturer manufacturer manufacturer manufacturer manufac- turer manufacturer manufacturer manufacturer 9a 46 bone level zikronia blasted manufacturer manufacturer manufacturer manufacturer manufac- turer manufacturer manufacturer manufacturer 9b 36 9c 34 9d 32 9e 42 9f 15 9g 11 9h 21 10 – machined collar yes yes yes, major yes, massiv no no – no 11 – bone level zikronia blasted no no yes yes, massiv yes no – no 12 – textured collar yes no yes, great yes, few no no – M-Line inside 13 – bone level zikronia blasted yes no yes yes – no – no 14 – machined collar yes no yes yes – no – no 116 245 316 444 533 615 743 815
