This case introduces a novel method utilizing partially demineralized dentin plates derived from extracted teeth for guided bone regeneration, showcasing its potential efficacy in addressing ridge deficiencies. Success, in this case, relies on meticulous sectioning of the tooth and processing of the dentin graft, precise adaptation and fixation of the graft to the residual ridge, and achieving primary closure for undisturbed healing. Limitations to success include the availability of teeth for extraction coinciding with the need for ridge augmentation and unstable graft fixation.
