Abstract

Endosseous dental implants have been successfully utilized for the last 3 decades to restore partially and fully edentulous patients with at least 3 months healing period of the alveolar bone following tooth extraction. An increasing number of clinical publications report on immediate implant restoration in the extraction. The advantages of immediate implantation after tooth extraction are shorter treatment time, fewer surgical procedures, and ensuring optimal tooth tissue aesthetics. Frequently, however, compromised teeth that are indicated for surgery are involved with acute and chronic infectious conditions which traditionally contraindicate their immediate restoration with dental implants. A review of current literature suggests that immediate implantation in infected sites should be avoided. Recent experimental studies have corroborated this clinical experience and shown that professional alveolar socket debridement and broad-spectrum antibiotics generate adequate conditions for the bone remodelling process around immediate dental implants placed into infected sites. Background: The immediate placement of dental implants into fresh non-infected sockets is an accepted successful technique, while placement of these implants into pathological Dento-alveolar sockets is still a controversial issue. Aim/Hypothesis: The aim of this clinical case-serious study was to report, retrospectively, the survival rate of immediate dental implants placed immediately after extraction of teeth with infected Dento-alveolar sockets in the maxilla and mandible at the osseointegration period (3 months). Materials and Methods: A retrospective analysis was made of the clinical and radiographic findings corresponding to 15 consecutive patients (7 women and 8 men, between the ages 21and 59 years) with a mean age of 44.14 years (SD= 9.28). A total of 36 locking-taper Bicon dental implants (hydroxyapatite, HA-coated) were immediately placed into infected fresh extraction- sockets included radicular cysts, chronic peri-apical lesions and sub-acute periodontal and endodontic infections using the flap or flapless surgery. Retrospective data on implant position, implant size, pathological condition, and baseline radiographs were obtained from patient records. Clinical and radiographic analyses were obtained to evaluate the treatment-outcome. Data were analyzed using descriptive statistics. Results: All the implants (N=36) except 2 achieved osseointegration in 3 months follow up. This reflects a 94.44% success rate within this small study group and 5.55% failure rate. Complications were related to the reasons for tooth loss. Conclusions: This retrospective clinical case-serious study showed the possibility that immediate dental implant placement might be successful in infected extraction sockets.
