There is paucity in the studies with long-term outcomes of the immediate loading of dental implants immediately placed into infected sites. This case-series aims to evaluate the long-term outcomes of immediate loading of post-extraction implants placed in infected sites in maxillary central incisors.
Material and methods:
Patients were selected if having post-extraction implants in the maxillary central incisors that were immediately loaded. Information were collected about patient’s demographic data, implant details, soft tissue stability and prosthodontic data. The marginal bone loss, implant and prosthesis survival rates were calculated.
Ten patients received 10 dental implants that were immediately placed after the extraction of upper central incisors. The implants were immediately loaded. The average follow-up time was 5.6 years (range 2-6 years). Only 1 of the 10 implants included in the study did not meet the criteria for implant success and survival of the implants was 100%. The mean marginal bone loss was 1.64 mm. No prosthesis failure was recorded. The soft tissues remained stable after treatment in 70% of cases, gingival recession was found in 20% of cases and loss of volume in the remaining 10%.
The immediate loading of implant inserted into fresh and infected extraction socket in upper incisors has not been a risk factor for implant survival. However, the stability of the peri-implant soft and hard tissues has indicated the need to take measures that minimize their loss.
