ARTICLE HIGHLIGHTS
Research background
At the patient’s request, we tried to perform immediate implant placement of the mandibular molars with CAP in clinical practice.
Research motivation
Most physicians consider the molars with CAP lesions as contraindications for immediate implant placement.
Research objectives
Immediate implant placement of the mandibular molars with CAP can achieve satisfactory 5-year clinical results.
Research methods
In this study, we retrospectively analyzed and compared the 5-year outcomes of immediate implant placement of the mandibular molars with CAP and those without obvious inflammation based on quantitative peri-implant bone mass changes evaluated using Simplant and Image J software.
Research results
The peri-implant bone density was 528.2 ± 78.8 Hounsfield unit (HU) in the CAP group and 562.6 ± 82.9 HU in the no-CAP group 5 years after implant placement. The peri-implant bone density did not differ significantly between the two groups. The marginal bone resorption or jump gap did not differ significantly between the two groups. In the CAP area, the gray values of the bone tissue immediately and 5 years after implant placement differed significantly from those of the surrounding bone tissue (P < 0.01).
Research conclusions
The results of this study suggest that immediate implant placement of the mandibular molars with CAP can achieve satisfactory 5-year clinical results, without significant differences in the complications, survival rate, or bone tissue condition from the no-CAP mandibular molars.
Research perspectives
Immediate implant placement of the mandibular molars with chronic apical periodontitis (CAP) can achieve good clinical outcomes.
