Treatment of open occlusions with onlay and overlay removable partial dentures.

The onlay removable partial denture has the primary purposes of restoration of esthetics and function through a conservative modification of the existing dentition. It is particularly applicable to open occlusion situations and in improving an uneven mandibular occlusal plane. Its use should be supplemented with specific instructions in proper cleansing and maintenance of underlying dentition and the prosthesis and with scheduled recall appointments.
