Fabrication of the trial denture and the try in procedure Flashcards
Things you need to know for the esthetic aspects during Selection and arrangement of artificial teeth
Esthetic aspects
* Color
* Color of skin
* Width of teeth *
Form
* Smiling
Selection and arrangement of artificial teeth
-> What should you know about The Smile line?
1mm of the incisal edge should be visible, when the upper lip is relaxed
In older patient the mandibular anterior teeth are more visible
Selection and arrangement of artificial teeth
Distance between the tips of the canines = __
width of nose
Selection and arrangement of artificial teeth
Width of centrals = __
width of philtrum
Selection and arrangement of artificial teeth
=> What should we know about selection of tooth forms?
Selecting tooth forms (in harmony with facial forms):
* Square face with square forms
* Oval face with oval forms
* Triangular face with tapered forms
Advantages of acrylate and ceramic teeth
- Shaping
- Chemical bonding
- Individualisation
- Cheap
- „Abrasion”
- Esthetic?
- Fracture…
disadvantages of acrylate and ceramic teeth
- Abrasion
- Light
- Discolouration
9 Methods for setting up the teeth
- Gysi
- Fisher
- Fehr
- Gerber
- Haller
- Hiltebrand
- Strack
- Monson
- Sears
How to do Arrangement of front teeth (Gysi)
The buccal and facial surfaces of the artificial teeth should follow the facial contour established by the wax rim
4 General principles of posterior tooth arrangement
- Muscular balance between tongue, lips, cheeks
- For effective occlusion requires 3 pairs of
antagonistic teeth on each side - Cusp-to-fossa relationship
- Bilateral balance occlusion
Arrangement of posterior teeth
-> What do the arrows indicate?
Wilson and Spee curve
What is Stop-line?
the distal border of the occlusal surface on the mandibular complete denture, on the lower alveolar ridge, just afore the ascending part of the alveolar ridge
What are the 3 Articulation forms?
- Canine guidance
- Unilateral balance
- Bilateral balance
Purpose of The Esthetic Try-In
- Evaluating
- Corrections
- Depending on the patient’s esthetic and emotional needs
5 steps of The Esthetic Try-In
- Inspecting the denture on the master cast
- Positioning the teeth on the articulator
3.Checking anterior teeth for shade, form, color, function - Checking posterior teeth for shade, form, color, function
- Checking the denture base form
(4 & 5 - Evaluating the final trial of dentures)
What do we need to do when Evaluating the final trial of dentures
Evaluating the length of the vestibular borders,the coverage of the retromolar pad area
