Mixin Classes in Odoo 17 How to Extend Models Using Mixin Classes
anatomy-for-complete-denture
1. Terminology
• Prosthodontics: the branch of dentistry that
deals with the replacement missing dental
,oral and craniofacial structure.
• Prosthesis: an artificial replacement of an
absent part of the human body.
2. • Dentulous: A condition in which complete set
of natural teeth are present in the mouth.
3. Edentulous :a condition in which the
mouth is without teeth it may be partially
edentulous or completely edentulous.
14. Lips
• Nasolabial Angle
– Angle between columella of nose & philtrum of lip
– Normally, approximately 90° as viewed in profile
15. • 4- Naso-labial sulcus:
Naso-
– Def.: it is a depression that extends from the ala of the nose
in a downward and lateral direction to the corner of the
mouth.
– Prosthetic importance:
it becomes more prominent with
aging and teeth loss so should be
restored by proper:-
– vertical dimension
- anterior teeth positioning
- labial flange
16. • Mento-labial sulcus
Mento- sulcus:
– Def.: it is the sulcus between lower lip and chin.
– Prosthetic importance:
its curvature indicates the character of maxillo-mandibular
relationship.
Class II angle Class I angle Class III angle
17. • Modiolus:
– Def.: this is located at the confluence of the
buccinator and other facial muscles near the angle
of the mouth.
– Prosthetic importance:
sunken cheeks appearance and
droped angle observed by loss
of maxillary teeth.
20. Residual ridge:
It is the portion of the alveolar process and its soft tissue coverage that
remains after extraction.
the highest continuous surface of the ridge is called
Crest of the ridge
Residual ridge is considered one
of the primary stress bearing area.
22. Maxillary tuberosity
It is a prominent bulge located just behind and above the distal end of the
maxillary ridge
well formed tuberosities offer wide coverage so enhancing support and
retention of the denture.
However extremely large ones
needs surgical correction.
27. Maxilla
• “Hamular” Notch
– Posterior border denture
• Between the bony tuberosity and hamulus
• “Soft displaceable tissue”, for comfort and retention
28. Maxilla
• Soft Palate
– Fovea Palatine
• Bilateral indentations near midline of the soft palate
• Close to the vibrating line
29. Maxilla
• Soft Palate
–Vibrating Line
• Critical posterior border dentures
• Junction of movable and immovable
portions of the soft palate
30. Mandible
• Ridge form
– U-shape best
– Non-moveable best
– Advise patient if poor
– Affects:
• retention
• stability
31. Mandible
• Pear Shaped Pad(retromolar pad)
– Soft pad containing glandular tissue
– Pear shape, posterior border
– Created from scarring after extractions
33. Mandible
• Buccal Shelf
– Primary denture bearing area of mandibular denture
– Between height of bridge & external oblique ridge
– Resorbs more slowly
34. Mandible
• Lingual Tori
– Raised bony structures
– May require relief when covered by a denture
– Thin mucosa can ulcerate easily
35.
36. Mandible
• Mylohyoid Ridge
– Origin of mylohyoid muscle which influences length
of lingual flange
– Can be prominent, and/or sharp, requiring relief
37. Mandible
• Genial Tubercles
– Attachment for the genioglossus muscle
– Tubercles may be higher than the ridge with severe
resorption
40. Frena (singular = frenum)
• Must be relieved to allow movement, without
impingement
• If prominent, adequate relief can weaken a denture
• If too much relief, retention is lost
• Check prominence intraorally
42. Limiting structures of maxillary
denture
Labial frenum
Labial vestibule
Buccal frenum
Buccal vestibule
Hamular notch
Vibrating line of soft palate
43. Limiting structures of mandibular
denture
Labial frenum
Buccal frenum
Lingual frenum Buccal
vestibule
Lingual pouch
Retromolar bad
44. • Retention :resistance to the dislodging forces along
the path of placement.
• Stability :to be firm, steady or constant to resist
displacement by functional horizontal or rotational
stresses.
• Support :the foundation area on which a dental
prosthesis rest. It is the resistance to the force
toward the tissue.

Because time passes… QUICKLY
And NEVER returns!
