Background: There is a growing need for prosthetic replacements in humans due to various reasons. Oro-facial deformities contribute more for these treatment modalities due to impairment in both function and esthetics. Biomaterials play an important role in replacing any form of defects. Selection of a good biomaterial is of prime importance as these materials determine the success of the treatment outcome. Acrylic resins and silicones are the most popular materials for replacing the lost tissues as far as the maxillofacial prosthesis is concerned. But these materials only help in covering the defect and give a very little therapeutic effect. Acrylic resins are very rigid materials and are less tolerated by the ailing patients. Silicones have very poor edge strength and colour retaining capacity. Purpose of Study: Hydrogels are hydrophilic gels which can be manipulated using polymeric network, are considered suitable maxilla facial materials. Hydro gels in dentistry can readily replace silicones as they have good physical, chemical and biological properties. They can also act as drug delivering devices which aids in healing of the defect and carriers for growth factors by which they stimulate the bone and tissue growth and they can be modified for their rigidity to have a good edge strength more recently. All these factors facilitate the hydrogels to serve as a good maxillofacial prosthesis material. Summary and Conclusion: Hydrogels are biocompatible materials which act as both therapeutic and replacement devices for the oro facial defects and can improve the patient's perception towards the positive outcome of the treatment.
