Abstract
Objective: To analyze the amount of crestal bone loss in maxilla and mandible around Bredent Sky Blue implants of different dimension a year after implantation. Material and Methods: 36 implants diameter 3.5 x 10 mm were inserted in the maxilla and 12 in the mandible. 52 implants diameter 4.0 x 8 mm were inserted in the maxilla, and 61 in the mandible (two-stage implant surgery). The data were analysed using the IBM SPSS v.17 software package (descriptive statistics, ANOVA -test). Results: No statistically significant differences were found between maxilla right, maxilla left, mandible right and mandible left side at implant sites regarding distal and mesial bone losses. Statistically significant differences were found between maxilla front, maxilla posterior, mandible front and mandible posterior at implant sites regarding distal and mesial bone losses. Conclusion: This study showed more bone loss for anterior implants compared to the posterior ones, but there was no significant different bone loss between maxillary and mandibular implants regarding sites.

Summary
The process of healing around the implant is similar to that in the normal bone tissue. Success of therapy is surgically, esthetically and functionally predictable only if we have sufficient bone and gingival tissue [3]. One of the most important criteria for evaluating implant success is determining crestal bone levels surrounding an implant [4]. Implant surgery in the posterior regions of the upper and lower jaws is in cases with a satisfactory bone volume of the alveolar process not difficult. In cases of alveolar atrophy the anatomical limitations with the maxillary sinus cavity and the alveolar nerve canal the situation becomes more problematic and has to be solved by different kinds of graft techniques. With the techniques which are available today most cases can be solved with good results [6]
