Implants and Magnets as Retentive Aids in Maxillofacial Region- A Review of Literature
Anchala Sarke, Himanshu Gupta, Roshika Sudan, Monika Subramaniyam, Ranjan Singh

Patients with facial or intraoral defects will seek treatment to address the loss of comfort, function or natural appearance. It is maxillofacial prosthodontist’s responsibility to provide prostheses that do not injure the remaining structures. As anatomy is altered, demands on residual structures increase. The field of maxillofacial prosthetics is embracing the rapid explosion of technology. The use of ossoeointegrated implants has broadened the treatment options. New technologies offer standardized quality, excellent precision of fit and outstanding biocompatibility, combined with adequate mechanical strength and provision for aesthetic design. Magnets in contact with saliva, magnets corrode and experience subsequent loss of magnetism. Encapsulating materials such as stainless steel is effective but susceptible to wear. Magnets therefore have a relatively short life, although more research is required to help the clinician determine their potential lifespan within the mouth. The development of samarium-iron-nitride may offer better resistance to corrosion, and its introduction into prosthodontics will be viewed with much enthusiasm.
Key words: Dental Implants, magnets, retentive, prosthesis.
