CLINICAL OUTCOME OF 2,560 IMPLANTS AFTER A MEAN OF 30-MONTH FOLLOW-UP

The advantage of implantology is to replace dental loss with a fixed prosthesis even in cases of partial or total edentulism without damaging the natural teeth. In the period between January 2008 and December 2013, 877 patients (498 females and 379 males) were operated at the BDD private Practice Clinic (Milan, Italy). The mean post-surgical follow-up was 30±17 months (max – min, 84 – 1). Two thousand five hundred and sixty out of 2,657 implants had a complete record and were evaluated in the present study. The implants were of different diameters and length, inserted both in mandible (1,327) and in maxilla (1,233) with immediate or delayed loading, and with graft, split crest, post-extraction, osteo-condensation, small and big sinus lift techniques, respectively. Fifty-nine out of 2,560 implants were lost (i.e. SVR = 97.7%). Cross-tabulation between failures and timing of loading (p= 0.008) had a statistically significant value, with a worse result for immediate loading (28 failures out of 783). In other comparisons between lost implants and diameter (p= 0.074), length (p=0.293), jaws (i.e. maxilla vs mandible, p=0.208), replaced teeth (incisors plus cuspids vs premolars plus molars, p=0.074), insertion torque (p=0.528), surgeons (p=0.452) and additional surgical procedures (i.e. split crest, post-extraction, graft, osteo-condensation, transposition, small and big sinus lift techniques, p= 0.713) no statistically significant difference was detected. EDIERRE Implant System SpA (Genova, Italy) implants have a high SVR (97.7%) allowing more simple surgical procedures for oral rehabilitation of partially or totally edentulous jaws.
