Reconstruction of the
intermaxillary relationships
Rest position of the mandible
• Then mandible is free between muscules
• The distance between the dental arches is appr. 2 mm
FRONTAL AREA
• Bipupilary line and the occlusal plane are paralell
• The occlusal plane goes through the incisal point (2mm
below the upper lip)
Rest position of the mandible
• Then mandible is free between muscules
• The distance between the dental arches is appr. 2
mm
POSTERIOR AREA
The occlusal plane is paralell to the nasoaural plane
The occlusal plane goes through mesiobuccal cusps og
the first upper molar
Vertical intermaxillary
relationship
• Two markers – subnasale, gnathion
• The distance for physiological rest position – the piece
of paper
• Find this distance on the wax templates
• Cut the wax template for 2 mm
Bite templates
• Wax wall and shellack or acrylic base
• Palec into oral cavity
• Cut with modellation knife upper template the wax wall lies – 2mm
below upper lip, paralell to the bipupillary line in frontal area and to
the nasoaural plane in posterior area
• Cur the lower template – wax wall acc to the upper (ir must fit on it)
untill the distance between two markers is in accordance to the
physiological rest position.
• Cut the lower wax wall for 2 mm – vertical intermaxillary relationship
Horizontal intermaxillary relationship
• The patients swallows, the head is in the position bend back
