Abstract
Customized porous titanium root-analogue implant (RAI) can be produced using CBCT data acquisition and three-dimensional image processing, combined with selective laser melting (SLM) technology. However, there is no report on the treatment of chronic periapical periodontitis with RAI. We report a case of longitudinal fissure of mandibular molars with periapical periodontitis and immediately implanted RAI after extraction. After a continuous observation for one year, it was found that the bone around the root grew into RAI and achieved a good effect of osseointegration. This report describes a situation in which traditional immediate implantation is untreatable, and the use of customized porous titanium RAI may open up new indications for immediate implantation.
