The invention discloses a personalized temporal-mandibular joint fossa implant which comprises an outer side retainer wing plate and a condyle process supporting surface, wherein the inner side face of the outer side retainer wing plate is in retaining fit with the outer side face of zygomatic arch of a patient; the lower edge of the outer side retainer wing plate and the condyle process supporting surface are connected into a whole; a top bulge is formed on the top surface of the condyle process supporting surface and positioned in a direction of the inner side face of the outer side retainer wing plate; the top surface of the condyle process supporting surface with the top bulge is attached to the temporal-mandibular joint fossa of the patient; the bottom surface of the condyle process supporting surface is attached to the lower condyle process head in a wrapped form; and the shape and size of the top bulge of the condyle process supporting surface and at least one of the width of the top surface and the width of the bottom surface of the condyle process supporting surface are in personalized matching according to the temporal-mandibular joint fossa and the lower condyle process head of the patient. The implant can be in close fit with the temporal-mandibular joint fossa of the patient, traumas and injuries of temporal-mandibular joint fossa implant surgery on peripheral tissues of the temporal-mandibular joint fossa can be reduced, and the joint fossa implant has high stability.
