ABSTRACT
Today, one of the most challenging aspects of esthetic implant modalities is to obtain a predictable immediate implant placement in post-extraction sites, without waiting for the site to heal. This is a treatment modality that has received much attention. Also implants can be successfully placed in human post-extraction infected sites. This prospective study investigates a comparison between osseointegration of immediate implant placement in fresh and infected dentoalveolar sockets. Ten patients [six males and four females] with a different mandibular tooth indicated for extraction were included in this study. Their ages ranged between twenty to fifty two years. Teeth extraction was done as a traumatically as possible; the ten patients were divided into two groups: where there was no periapical pathosis after radiographical examination was referred to as group I, while those who had periapical pathosis identified on radiographical examination were referred to as group II. Each patient was evaluated clinically and radiographically immediately after operation, and 1.5, 3 and 6 months post-operatively. There was no statistically significant difference in the changes which occurred in both group I and group II. The percentages of changes were calculated in relation to the baseline at postoperative records. However the percentage of changes between the two groups at different follow up periods were steady immediately after operation, six weeks and twelve weeks, and it significantly decreased at the last follow up after six months. Immediate implant placement in a fresh socket and also infected socket proved to be of great benefit to both the dentist and the patient as it eliminates the need for second stage surgery and an additional healing period, decreases the total time, better preserves soft tissue contours and height in esthetic zones, reduces overall cost and results in better osseointegration
