22. Definition: “the characteristic features that occur when an edentulous maxilla is opposed by natural
mandibular anterior teeth, including loss of bone from the anterior portion of the maxillary ridge,
overgrowth of the tuberosities, papillary hyperplasia of the hard palatal mucosa, extrusion of mandibular
anterior teeth and loss of alveolar bone and ridge height beneath the mandibular removable partial
denture bases, also called anterior hyperfunction syndrome.
45. compound maxillary rim trimmed buccally and lingually so that the occlusion is free in lateral excursions.
Carding wax added to the compound rim, and the patient is instructed to perform eccentric chewing movements. The carding
wax is slowly molded to the functional movements
The generated occlusion rim is now removed from the mouth, and stone is vibrated into the wax paths of the cusps.
The upper cast is again fastened to the articulator with the generated occlusion rim and the stone cusp path record. The stone
cusp path record is secured to the lower member of the articulator with plaster.
46. Now we have two lower casts.One is a duplicate of the lower teeth and the other is a
replica of the generated path.
The denture teeth are first set to the lower cast of the patient’s teeth.
After the esthetics have been approved at the try-in, the lower cast is removed and the
lower chew-in cast record is then secured to the articulator.
All interfering spots are carefully ground until the incisal guide pin prevents further closure.
Thus, in centric and in eccentric movements maximum bilateral balanced occlusion will
have been established

50. First, the upper cast is mounted on an articulator using a face-bow with an orbitale pointer.
The lower cast is related to the upper by a centric interocclusal record at an acceptable vertical dimension.
The buccal-lingual position of the lower teeth and their relation to the upper arch is studied.
A decision whether to articulate the central fossa of the denture teeth to the lower buccal cusps or to the lower
lingual cusps must be made.

61. • Occlusion should be modified first.
• Resilient attachments are used.
• Advantages :improved speech,retention,lip support.
