Abstract
The present study was employed in an attempt to evaluate the dental implants placed immediately post-extraction and immediately loaded, in patients suffering from aggressive periodontitis, clinically and radiographically.
Twenty implants were included in this study. The implants were installed immediately after periodontally hopeless teeth extraction in the anterior mandible of twelve aggressive periodontitis patients. The patients were divided into two groups six patients of each; the immediate loading group (Group1) and the delayed loading group (Group2). Each group received ten implants. Group1 received the final porcelain-fused-to-metal (PFM) restoration within 72 hours after implant installation, while group 2 received the final PFM restoration after 6 months of implant installation. Success rate was 90% for group1 and 100% for group 2 after one year follow up.
The clinical follow up was nine months and twelve months after implant placement including probing depth, gingival index and plaque index. The difference of the means of the clinical follow up measures between both groups were statistically insignificant (p<0.05).
The radiographic follow ups were performed one week, three months, six months and 12 months after implant placement. Crestal bone changes level were measured using Digora Software showing statistically insignificant difference between both groups (P<0.05). Bone density changes around dental implants of group1 were measured using IDRISI Kilimanjaro software showing statistically significant higher bone density at the 3-month follow up. Bone density changes around dental implants of group2 showed statistically significant higher bone density at the 6-month and 12-month follow up (P<0.05).
