Evidence
The highest percentage of the edentulous ridges are Class 1. Free end dentures in the mandible,
needed a higher percentage of adjustments of the denture base. This phenomenon is due to
the progression of the resorption in the edentulous parts of the alveolar ridge, which is
accentuated by the amount of pressure on the free end prostheses.
Most patient acceptance on the major connector in maxilla is for the antero-posterior bar. For
this case, for better retention, lingual plate is a great major connector type.
Possibility of vestibuloplasty to improve the ridge form, and implant retained overdentures- but
patient finances is a concern. Precision attachments are also a good form to try, given the RPD
mpstly fail due to caries, periodontal problems and mobility.
