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

Abstract

The esthetics and functional integrity of the periodontal tissue may be compromised by dental loss. Immediate implants became a viable option to maintain the periodontal architecture because of their anatomic compatibility with the dental socket and the possibility of eliminating local contamination. This article describes the procedure of immediate implant placement in the anterior maxilla replacing teeth with chronic periapical lesions, which were condemned due to endodontic lesions persisting after failed endodontic treatment and endodontic surgery, and discusses the relationship between the procedure and periapical lesions. Surgical removal of hopeless teeth 11, 12 and 21 was performed conservatively in such a way to preserve the anatomy and gingival esthetics. A second surgical access was gained at the apical level, allowing the debridement of the surgical chamber for elimination of the periapical lesion, visual orientation for setting of the implants and filling of the surgical chamber with xenogenous bovine bone graft. After this procedure, the bone chamber was covered with an absorbent membrane and the healing screws were positioned on the implants. Later, a provisional partial removable denture was installed and the implants were inserted after 6 months. After 3 years of rehabilitation, the implants present satisfactory functional and esthetic conditions, suggesting that immediate implant placement combined with guided bone regeneration may be indicated for replacing teeth lost due to chronic periapical lesions with endodontic failure history in the anterior maxilla.

Effect of PRF and Allograft Use on Immediate Implants at Extraction Sockets with Periapical Infection —Clinical and Cone Beam CT Findings—

“…Many studies have investigated immediate implant placement in infected extraction sockets due to periapical lesions 5,12,13,17,20,24,31,32,35,55) . Few have investigated the potential adjunctive effect of concomitant use of PRF and DFDBA bone grafts in such cases, however, which was, therefore, the purpose of the present study.…”

“…A high rate of implant failure has been reported in sockets with periapical lesions, especially with placement of machined-surface implants 5) . Moreover, many studies have reported an increase in loss of endosseous implants at sites associated with periodontal disease 12,24,35) , whereas few have reported satisfactory results 13,20) . Similar success rates have been reported, however, with immediate implant placement whether the site was infected or not, provided infection was controlled thorough debridement of alveolar tissue by curettage and administration of broad-spectrum antibiotics 17,20,31,32,50,55) .…”

Immediate Placement of Dental Implant on Freshly Extracted Socket: A Case Report From B. P. Koirala Institute of Health Sciences, Dharan

“…However, periapical pathology can be contraindica ons for placing the implants without 6,7 regression of the lesions. Some authors claim success even [8][9][10][11] in such condi ons with proper debridement and care. Thus immediate implant placement has less contraindica ons in modern era of den stry.…”

A Radiographic Classification for Retrograde Peri-implantitis

“…Twelve of the articles were excluded as they had no IOPAs of the lesion. 7,11,24,25,33,35,[37][38][39]45,48,53 A total of 54 IOPAs from 36 articles were compiled. One periodontist (SR) and one implantologist (TAB) independently analyzed the IOPAs.…”
