*Implant-Retained Maxillary and Mandibular Overdentures - A Solution for Completely… DOI: http://dx.doi.org/10.5772/intechopen.99575*

implant-supported mandibular prostheses considered removable types to be a first class treatment [51, 52]. Half of the primarily older individuals monitored in this trial preferred removable over fixed prostheses for easier cleaning and ability to take them out during the night, but reported to be less efficient for chewing [51, 52]. Therefore, this finding should be used by clinicians when choosing the most appropriate type of dentures in completely edentulous patients, too.

It is also important to mention that both clinical and dental laboratory procedures when fabricating implant-retained maxillary and mandibular overdentures do not differ significantly from the conventional on, with the exception of the use of implant transfers, laboratory analogs and individually adjusted trays (**Figures 6**–**8**).
