denture teeth selection

• Loss of muscular tone
• Reduced biting  force 
•  Fatigue of facial muscles
• TMJ problems
• Esthetics compromises
• Angular cheilitis
• Interference with ear function
• Reduction of the tongue space

• Bone resorption
• Continued ridge soreness
• Gagging
• Muscular fatigue and discomfort
• Decreased masticatory efficiency
• TMJ problems
• Clicking of teeth during speech
• Difficulty swallowing

• Physiologic rest position 
• Phonetics and esthetics
• Swallowing
• Comparison with the old denture

• Rounded arch form
• Rounded corners
• Anteriors closely follow the lower lip
• Laterals overlap centrals
• Smaller laterals and cuspids
• Sharp canines

• Angular outlines
• Larger laterals and canines
• Square arch form
• Centrals overlap laterals 
• Blunt canines

• Poor Residual Ridges
• Poor Neuromuscular control (Bruxers, CP etc.)
• Previously successful with Monoplane Dentures or Severely worn occlusion on previous denture
• Arch discrepancies
• Class II or III or Cross-bite
• Immediate Dentures
• except when opposing natural dentition
• Potential poor follow-up

• Good Residual Ridges
• Well Coordinated Patient
• Previously successful with anatomic dentures
• Denture opposes natural dentition
• When “Lingualized” occlusion is desired

• Advantages:
• Reduction of horizontal forces
• CR can be developed as an area instead of a point
• Freedom of movement
• Can develop solid occlusion despite arch alignment discrepancies
• Easily adapted to situations prone to denture base shifting
• Easy to set and adjust teeth
• Disadvantages:
• No vertical component to aid in shearing during mastication
• Occlusal adjustment impairs efficiency unless spillways and cutting edges restored
• Patients may complain of lack of positive intercuspation position
• Somewhat esthetically limited (don’t look like natural teeth)

• Definite point of positive intercuspation may be developed
• Esthetically similar to natural dentition
• Tooth-to-tooth and cusp-to-cusp balanced occlusion can be achieved
• Maintains some shearing ability after moderate wear

• Difficult to set
• Less adaptable to arch relation discrepancies
• Horizontal force development due to cusp inclinations
• Harmonious balanced occlusion is lost with denture base settling
• Requires frequent follow-up and may require more frequent relines to maintain proper occlusion

• Mount maxillary cast with facebow record
• Mount mandibular cast with centric relation record
• Arrange anterior and posterior teeth

With this angular shape, the central incisor is dominant and the gingivo-incisal curvature is moderate. The square facial shape offers maximum light deflection and creates a bold effect.

• Characterized by rounded contours which taper towards
• the cervical ridge. Moderate gingivo-incisal curvature.
• Large triangular incisor slightly triangular in shape.

• Ovoid:
• The teeth have a
• pronounced gingivo-incisal curvature, which tends to disperse the light reflection and create a softened appearance.

• In the majority of pts., a relationship exists
• between the inner canthus measurement
• and the distance between distals of the
• maxillary laterals. This measurement can
• then be carried directly to select the proper
• maxillary anterior teeth.
• Determined by:
• Evaluation of existing denture
• Old photographs
• Width of the six anterior teeth with a flexible ruler
• Trubyte tooth selector
