Impact of local and systemic factors on the incidence of oral implant failures, up to abutment connection

Abstract

The indication for the use of oral implants should sometimes be reconsidered when alternative prosthetic treatments are available in the presence of possibly interfering systemic or local factors.

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

“…This is possibly due to bacterial contamination of the implant surface during the initial stages of healing 8,46) . 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) .…”

Dental Implant Fractures – Aetiology, Treatment and Case Report

“…When it happens before or at abutment insertions, it is considered as an early failure, and it may be attributed to drawbacks which occur during osseointegration healing phase. On the other hand, after occlusal loading [Table/ Fig-2], any problem which occurs with the implant-prosthesis set is considered as a late failure, and it is related to any process that may affect the maintenance of previously established osseointegration [11].…”

Prosthodontic complications associated with implant retained crowns and bridgework: a review of the literature

“…18 Late implant loss has been associated with occlusal overload, peri-implantitis, poor bone quantity and poor bone quality. 18,22 The reported survival rates for implants supporting crowns and fixed partial dentures exceed 95% over 5 years 2,6,7 and 93% over 10 years. 6,7 However, survival does not equate to success and these rates must be interpreted cautiously because a surviving implant may be failing, unrestorable or may have had extensive remedial treatment.…”

“…16 When implant loss occurs, it occurs before functional loading in approximately 55% of cases. 4,22 When an implant fails an alternative treatment may be considered, the site may be allowed to heal before placing a new implant (Figs 10 and 11) or a new, wider implant may be placed immediately. 23 There is limited evidence to suggest that implants placed at the site of previously failed implants have lower survival rates.…”
