PDF: Immediate implants placed into infected sockets: a case report with 3-year follow-up

Endodontic failures, like persistent infections, must be considered among the factors that lead to tooth loss. 

Immediate-implants


Periapical lesions are areas of inflammatory reactions to various antigens present in infected root canals.

Histological examination of these lesions reveals the presence of granulation tissue infiltrated by immunocompetent cells such as lymphocytes, plasma cells, macrophages, polymorphonuclear leukocytes, and mast cells.

Macrophages and lymphocytes are the predominant inflammatory cells. 

Microorganisms located at the apical part of the root canal system are usually delineated from the inflamed periradicular tissues, either by a dense accumulation of polymorphonuclear neutrophils or by an epithelial plug at or near the apical foramen.

The placement of immediate implants represents an alternative to compromised teeth involved with infectious conditions. 

Alveolar ridge resorption after tooth extraction may considerably reduce the residual bone volume and compromise the favorable positioning of implants required for optimal restoration.
