Svrha: Godinu dana nakon ugradnje želio se analizirati gubitak alveolarne kosti u maksili i mandibuli oko implantata BREDENT Sky Blue različitih dimenzija. Materijali i metode: U maksilu je bilo umetnuto 36 implantata promjera 3,5 x 10 mm, a u mandibulu 12. Uz to, 52 implantata promjera 4,0 x 8 mm ugrađena su u maksilu i 61 u mandibulu (dvostupanjska implantacijska operacija). Rezultati: Nije bilo statističke razlike u gubitku kosti između maksile desno i lijevo te mandibule desno i lijevo na mjestima implantacije mezijalno i distalno. Rezultati su dobiveni analizom varijance (ANOVA). Zaključak: Statistički značajna razlika u gubitku kosti zabilježena je između maksile sprijeda i straga te mandibule sprijeda i straga na mjestima implantacije distalno i mezijalno. Rezultati su dobiveni analizom varijance (ANOVA)., Purpose: The aim of the study was to analyze the amount of maxillary and mandibular crestal bone loss around Bredent Sky Blue type of implants of different dimensions one year after implantation. Materials and Methods: 36 implants of diameter 3.5 x 10 mm were inserted in the maxilla and 12 in the mandible. 52 implants of diameter 4.0 x 8 mm were inserted in the maxilla, and 61 in the mandible (two-stage implant surgery). Results: No statistically significant differences were found between the right and left side of the maxilla and between the right and left side of the mandible at the implant sites regarding distal and mesial bone losses as shown by analysis of variance (ANOVA). Conclusion: Statistically significant differences were found between anterior maxilla, posterior maxilla and anterior mandible and posterior mandible at implant sites regarding distal and mesial bone losses as shown by analysis of variance (ANOVA).
