Abstract
The advancement of implant dentistry has ushered in innovative solutions to overcome the limitations of traditional implants, notably the absence of the periodontal ligament (PDL). Ligaplants—a hybrid of biocompatible implant material and bioengineered PDL—represent a paradigm shift in dental rehabilitation. These next-generation implants aim to recreate the natural tooth attachment apparatus by integrating tissue engineering techniques, including the use of scaffolds, signalling molecules, and stem cells derived from dental follicle or PDL tissue. This review explores the development, preparation, biological integration, and challenges associated with Ligaplants. While still largely experimental, animal studies and early clinical trials suggest that Ligaplants may restore proprioception, distribute occlusal forces more physiologically, and promote bone regeneration without the need for grafting. Despite high costs, ethical concerns, and the complexity of culturing PDL tissue, Ligaplants hold immense promise as a biologically functional alternative to osseointegrated implants, offering new horizons in regenerative dentistry.
