Introduction to complete edentulism, digital denture workflow, oralmy of complete dentures
anato
1. Increase in esthetic awareness: What has prompted an increase in patient demand for quality removable
prosthodontic restorative treatment
2. Intra-oral scans
3D printed record base + wax rims, BMFI+JRR 3D printed denture
try in
Milled denture placement: What is the digital workflow of edentulous patients without dentures
3. Scan pre-existing complete dentures 3D-printed
copy of denture, BMFI+JRR 3D printed denture try in
Milled denture placement: What is the digital workflow for edentulous patents with pre-existing dentures
4. Convex: What is the typical facial profile in a dentate patient
5. Becomes straighter or concave: What happens to the facial profile of a eden- tulous patient as resorption occurs
6. Becomes greater: What happens to the angle of the colummela and the philtrum in an edentulous patient
7. Modiolus, buccinator, mentalis, incisivus labii superiorus, incisivus labii inferiorus, orbicularis oris: What
are the muscles of facial expression
8. Modiolus: A concentration of several muscle groups and is situated laterally and slightly superiorly to the corner of
the mouth.
9. Modiolus: This is an area where extrinsic perioral muscles join intrinsic fibers of the orbicularis oris muscle
10.Modiolus: A very forceful area which can influence the labial flange thickness of the maxillary denture
11.Buccinator: Provides support and mobility of the soft tissues of the cheek. The muscle fibers contract in a line
parallel to the plane of occlusion. As people age, tension is lost in the muscle which predisposes to cheek biting.

12.Mentalis: Elevates the skin of the chin and turns the lower lip outward.
13.Mentalis: Dictates the length and thickness of the labial flange extension of the lower denture
14.Incisivus Labii superioris and inferiorus: Their actions on the vestibular space are similar to that of the
mentalis
15.Orbicularis oris: The sphincter muscle of the mouth. Has no skeletal attach- ments, is a composite muscle,
composed not only of intrinsic but also extrinsic fibers of many muscles that converge at the Modiolus
16.Muscles of facial expression: What muscles generally do not insert in bone and need support from the teeth and
denture flanges for proper support and function

17. Anatomy and physiology of the edentulous patient
A thorough knowledge of the origins and kinetics of the muscles of mastica- tion, facial expression, tongue and
floor of the mouth is essential: In order to properly construct a denture what must one understand?
18.Retention, stability, support: What are the 3 major parts of the prosthodontic assessment of complete dentures
19.Retention: Resistance to vertical displacement of the denture away from the denture bearing surface during
function
20.Stability: Resistance to lateral displacement of the denture during function
21.Support: Resistance to vertical forces of occlusion. Factors of the bearing surface that resist or absorb
occlusal loads during function.
22.Key anatomic landmarks and their roles with respect to retention, stability, support, preservation and
esthetics: What needs to be mastered so that dentures can be fabricated as integral parts of each patients oral cavity and
not just mechan- ical artificial substitutes
23.Nature of the bearing mucosa, bone contours, muscle attachments: Factors that impact retention, stability and
support
24.Labial vestibule: Peripheral or limiting structures that run from one buccal Frenum to the other
25.Frenum: Folds of mucous membrane that do not contain significant muscle fibers.
26.High Frenum attachments: What type of Frenum attachments will compromise denture retention and may require
surgical excision
27.Labial vestibule: When this vestibule is properly filled with denture flange it greatly enhances stability and
retention
