Radiographic Evaluation Cervical Crestal Bone Resorption around Dental Implants in Maxilla and Mandible: One Year Study

摘要

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. Materialand 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.
