Abstract

The invention discloses a personalized mandible substitute compounded with an autologous bone. Two ends of a substitute are respectively provided with a fixing wing plate to realize connection with anatural mandible, and the upper part of the substitute is provided with a fixing groove for fixing an autologous bone; bone fusion areas are arranged in contact areas of two ends of substitute and natural mandible, the contact area of the fixing wing plate and natural mandible and the contact area between the substitute and autogenous bone and a soft tissue fusion area is arranged in the area, making contact with the surrounding soft tissue, of the substitute so as to promote fusion of the substitute and the surrounding tissue, improve the biocompatibility of the substitute and enhance the biomechanical strength of the substitute; and the rest is a mandible body supporting area. According to the invention, a problems of autogenous bone shortage, difficult shaping, poor fusion of a thermoplastic material as a mandible implant with natural bone tissues and surrounding soft tissues and the like can be solved, so that the fusion of the mandible substitute and the surrounding tissues is promoted, the healing of a wound after the substitute is implanted is accelerated, and the living quality of a patient is further improved.

Description

technical field [0001] The invention belongs to the technical field of mandibular repair, and in particular relates to a personalized mandibular substitute compounded with autologous bone. Background technique [0002] The mandible is the largest bone in the maxillofacial region of the human body, and it is also the main supporting structure of the facial shape. Mandibular defects are more common in maxillofacial defects, which can be caused by trauma, tumor resection and other reasons. Mandibular and adjacent soft tissue defects caused by mandibular defects often lead to serious facial deformities and dysfunction, which seriously affect the physical and mental health of patients and reduce their life satisfaction. [0003] At present, bone transplantation is often used clinically to repair mandibular defects, including autologous bone, allogeneic bone or xenograft bone transplantation and artificial bone substitute transplantation. Among them, autologous bone transplantat...
