Tooth Selection Flashcards
Antieror teeth selection is primary selected for what
To meet the aesthetic demands
Posterior teeth is primarly selected for what
For its function
When do we select the antieor teeth
EARLY before the final impression and the anti and post should be ordered together
Guides to select anti teeth
1- pre-extraction record \ photos radiographs or cast
2- facial profile and apperance
3- arch size and form
4-gender and age and personality
5-paitens relatives
6- patients prefrance
7-existing denture
Square Tooth Molds
1-angular shape
2-gingivo-incisal curvature is moderate
3-centra incisor is dominant
4- offers maximum light REFLECTION
5- bold affect
Tapering Characterized by
1- rounded shape
2-tapers toward the cervical
3- moderate gingivo-incisal curvature
4-large triangular incisor
Ovoid characterized by:
1-pronounced gingivo-incisal curvature
2-scatter the light reflection
3-create softened appearance
Dentogenics concept (Frush and Fisher)
Is a concept that integrated the selection of teeth into an esthetic system governed by age, sex and personality of the patient
The dentogenic concept (sex)
Males tends to have more square and bold central incisors
Females have more pronounced curvature and round point angel
Dentogenics concept (age)
Children: tappired ovoid and round
Olds : square and sharp corners
Bold Characteristics
1- angular outlines
2- central overlaps the lateral
3- large central and lateral
4-blunt cannine
5-square arch form
Soft Characteristics
1- lateral overlaps the central
2- antireors follows the lower lip
3-round teeth corner
4-rounded arch form
5-smaller lateral and cuspid
6- pointed canine
Sequence of Anterior Tooth Selection
1- size. 2- middle form. 3- shade
When selecting the anterior teeth we have to take into consideration
1-lip support
2- occlosal plane
3- vertical dimmention of occlusal
4- aesthetic
What do we mark on the mx rim?
1- midline
2-high smile line ( where we place the neck of the central incisor)
3- relaxed corner
4- junction of the commissure of the lips or interalar width ( which where the distal proximal surface of the canine would be )
Trubyte tooth indicator used for what
To estimate the size and outline and profile of the anti mx
What is the average raito between the bizygomatic width and length of the face and W-L of the teeth?
16:1
Facial-meter Blue line form selector
A meter that compare or see the width of both the nose and central incisor
interprets the teeth measurement and gives a suggested list of tooth molds that fit into the patient’s individual inter-alar measurement
Facial meter - Ivoclar Vivadent -
After we select the shade based on the paitents skin color and hair and also the sclera we show them the shade in 3 positions
1- outside the mouth and beside the cheek
2-below the upper lips and only show the incisal edge of it
3- below the lower lip with the mouth open and 2/3 to 3 to 4th are exposed
Hirsch B. et al., J.P.D. 1972
This study concluded that
regarding aesthetic problems in complete denture, to obtain a satisfactory result for the patient and for the dentist, it is very important to involve the patient in decision-making.
Posterior mold selection
The selection is based on the anteriors
And the selection is the dentists responsibility
Considerations of posterior tooth selection
1- mastication
2-ridge preservation
3-soft tissue heath
4-denture stability
5-esthetic
The mesiodistal length of the posterior teeth is determined by
The length of the md ridge
Post teeth are not set on the slope from ?
Residual ridge to the retromolar pad to avoid inclined plane
