Defects or deformities in the head and facial area almost always lead to a severe emotional burden requiring rehabilitation. The use of craniofacial implants is an effective treatment for Patients with deformities, burns and cancers sequelae. The swede Per–Ingvar Branemark succeeded in 1950s in discovering that titanium possesses an exceedingly high compatibility in bones.He coined the term osseointegration.This concept of Osseointegration, made titanium suitable for dental implants.The first use of percutaneous titanium fixtures outside the oral cavity was by the Oto-rhinolaryngologist Anders Tjellstom in 1977 for a bone anchored hearing aid, and in 1979 for a bone anchored prostheses. Grouped implantsystems were developed following solitary extra-oral implant systems which may be placed more reliably in areas with low bone presentation, as in the nasal and orbital region, or the ideally pneumatised mastoid process. Today, even large facial prostheses may be securely retained.This review outlines the important features of extra-oral implantology.
