MEDPOR Implants in Rehabilitation of Maxillofacial Defects
Polyethylene or MEDPOR has many advantages for medical implants as a biomaterial and is applied to fabricate polyethylene implant which is of high density and porous in nature for facial and cranial reconstruction. It is semi crystalline polymer and with high fracture toughness. They are made up of straight chain which is aliphatic in nature. MEDPOR implant comprises of medical grade, high density polyethylene which is sintered to make a flexible framework of pores which are interconnected. The treatment of maxillofacial defects is tough due to technologies shortcomings which donot provide regular protocol to re establish patient-specific anatomy. Due to increase in usage of implants in various types in restorative dentistry, use as maxillofacial prosthesis has become famous, even proven beneficial in varied number of clinical management. The material being highly stable, flexible, porous, rapidly vascularized, tissue ingrowth property makes it sustainable for its use in maxillofacial defects and aesthetic surgery.
MEDPOR implants can be extensively used for ear, nose and orbital deformities. In cases of ear defects like microtia or complete loss of ear, in cases of trauma caused to nose while an accident or involvement of structures which are in close proximity with nose, eye loss or any other orbital or ocular defects MEDPOR implants has come out with flying colours.
