This document provides information on making complete denture impressions. It defines an impression as the negative form made of oral tissues using a plastic material. A complete denture impression captures the entire denture bearing area of an edentulous mouth. Preliminary impressions are used for diagnosis and tray construction, while final impressions make master casts for denture fabrication. Key objectives of impressions are preservation of ridges, stability, support, esthetics and retention. The document outlines techniques for primary maxillary and mandibular impressions using stock trays and high viscosity materials like alginate or impression compound. Common errors in impressions include gaps, excess material, shallow sulci and visible tray edges. Corrections involve adding material or remaking impressions.

The Pt. adaptation on his complete dentures are based on the ability of the dentures to restore the missed functions due to the loss of the teeth. Good impression is the first step in the success of the complete dentures. A trial to review all the basics necessary to have a good impression is exposed in this lecture.
The anatomy of the edentulous ridge in the maxilla and mandible is very important for the design of a complete denture. Objective in fabrication of a complete denture is to provide a prosthesis that restores lost teeth and associated structures functionally, anatomically and aesthetically as much as possible with preservation of underlying structures and the knowledge landmarks help us in achieving our objective.

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder
2. DEFINITION
o AN IMPRESSION is the negative form of the
teeth and/or other tissues of the oral cavity
made in a plastic material that becomes
relatively hard or set while in contact with these
Tissues.
oA COMPLETE DENTURE IMPRESSION
is a negative registration of the entire denture
bearing, stabilizing and border seal area
present in the edentulous mouth.
(Heartwell 5th edn.)
3. IMPRESSION TYPES
PRELIMINARY (Primary)
IMPRESSION
PURPOSE
•Diagnosis
•Construction of tray
FINAL (Secondary)
IMPRESSION
• Making master casts
used for making dentures
4. PRINCIPLES AND OBJECTIVES
OF IMPRESSION MAKING
The impression technique for CD must strive to accomplish the following
five primary objectives:PRESERVATION: The preservation of remaining residual ridge is one
of the important objectives of impression making.
STABILITY: It refers to the resistance against horizontal movement and forces
that tend to alter the relationship between the denture base and its supporting
foundation in a horizontal/rotatory direction.
Close adaptation to the undistorted mucosa is most important for stability.
Stability decrease with the loss of vertical height of the ridges or with increases
in flabby movable tissues
5. SUPPORT: It is the resistance of a denture to the vertical
components of mastication and to occlusal or other forces
applied in a direction towards basal seat.
Maximum coverage provides the ‘SNOWSHOE’
effect which distributes applied forces over as wide
an area as possible .
This helps in:oPreservation
oStability
oRetention
6. ESTHETICS
Border thickness should be varied with the
needs of each patient in accordance with the
extent of residual ridge loss.
The vestibular fornix should be filled but not
overfilled, to restore facial contour.
7. RETENTION
Retention for a denture is its resistance to removal in a
direction opposite that of its insertion or
Resistance of a denture to vertical movements away
from the tissues (Prosthetic Dent. Glossary 1995
Quintessence).
The quality inherent in the prosthesis acting to resist the
forces of dislodgment along the path of insertion. (GPT
1999 7th edn.)..
8. BASIC CONCEPTS TO ACHIEVE
A SUCCESSFUL IMPRESSION
The tissues of mouth must be healthy.
Impression should extend to include all of the basal seat
within the limits of the health and functions of the supporting
and limiting tissues.
Borders must be in harmony with the anatomical and
physiological limitations of the oral structures.
9. Proper space for selected impression material should
be provided within the impression tray.
A physiologic type of border molding procedure should
be performed by the dentist or by the patient under the
guidance of the dentist.
Selective pressure should be placed on the basal seat
during the making of impression.
10. The impression should be removed from the mouth
without damage to the mucous membrane of the residual
ridges.
A guiding mechanism should be provided for
positioning of impression tray in mouth.
The tray and impression material should be made of
dimensionally stable materials.
External surface of impression should be similar to the
external surface of complete denture.
11. AIM OF PRIMARY IMPRESSION
Record the denture bearing areas of each arch in stock
metal trays.
According to the guides to standards in prosthetic dentistry
there are basic requirements required for primary
impressions.
12. THE MINIMAL REQUIREMENTS OF AREAS TO BE RECORDED IN
PRIMARY IMPRESSIONS FOR COMPLETE DENTURES
MAXILLARY ARCH
Residual ridge including
full extent of the tuberosities
and hamular notch.
Functional depth of labial
and buccal sulci, including
fraenae and muscle
attachments.
The hard palate and its
junction with soft palate.
13. MANDIBULAR ARCH
Residual ridge, including the
full extent of retro molar pads.
Functional depth of labial and
buccal sulci, including fraenae,
muscle attachments and
external oblique ridges.
The lingual sulci, lingual
frenum, mylohyoid ridges and
retromylohyoid areas.
(BDJ)
14. IMPRESSION TRAYS
For primary impression we use stock metal/plastic trays
of varying sizes that are available.
-Trays are the most important part of impression making
procedure
Non perforated impression compound
Perforated alginates, silicone putty
15. Too large a tray will:-
Distort tissue around the border of impression.
Pull soft tissues under the impression away from
bone.
Distorting dimensions of sulcus.
16. Too small a tray :–
the border will collapse inward onto the residual ridge.
Distort dimensions.
Proper support of lips is lost
17. Preliminary impression should be as accurate as
possible
At times even a correctly selected stock tray will
not fit the denture – bearing area perfectly.
Therefore select a impression material that has
relatively high viscosity thereby allowing the
material to compensate more easily for the
deficiencies of the tray.
18. Most suitable materials for primary impression are
1.Silicone putty
-Addition difficult
-High viscosity – poor surface details
2.Alginate
Accurate detail
Simplicity of equipment needed
Ease of manipulation
Little discomfort to patient
Short chair time
Dimensionally unstable
19. 3.Impression compound
-Thermoplastic
-High viscosity
-Support itself
-Additions possible
-Poor surface details
-Inelastic
–hence undercuts not
recorded
4.Impression plaster
MATERIAL OF CHOICE FOR MOST DENTIST
CURRENTLY IS HIGH VISCOSITY ALIGINATE
IMPRESSION MATERIAL.
20. PRIMARY IMPRESSION
•Position of patient
-Seat patient in upright comfortable position
with
the occiput firmly resting in the head rest.
-Allay’s fear of patient of being chocked by
impression material
-Head and neck should be line with trunk
it Relaxes infra and suprahyoid muscles (swallowing
movements easy)
-Prevents easy fall of impression material fragment
(if any) in throat
-Cover the patient to protect patients clothing.
-Warm, flavored mouth wash for rising.
22. TRAY SELECTION FOR MAXILLARY PRIMARY IMPRESSION
An edentulous stock tray that is
approximately 5-6 mm larger than
the outside surface of residual ridge
is selected.
Place the tray in the mouth and
position it by centering the labial
notch of tray over the labial frenum.
Posterior extent of tray relative to
PPS is maintained and the handle is
dropped downward the permit visual
inspection.
Examine the extension of tray
flange at buccal and labial areas.
23.
24. The fingers of one hand are
shifted into the middle of tray
and border molding is carried
out.
The labial and buccal vestibule
are molded by asking the
patient to suck down onto the
tray.
Move mandible from side to
side to record the distobuccal
area and influence of coronary
process and shape of buccal
vestibules
25. Open wide to record pterygomandibular
raphe.
Asked the patient to suck the finger of the
operator – establishes impression of posterior
aspect of upper impression
26. COMMON FAULTS IN UPPER IMPRESSION
1.
A crevice in the midline of palatal posterior third.
Causes
Insufficient composition in palatal area when fitting the
tray.
Insufficient pressure
2. Excessive composition extending well beyond the
posterior palatal border of tray
Causes
Excessive pressure or too prolonged pressure when
seating the tray.
Too much compound in palatal area
27. 3. An impression short in one or more regions of sulci,
especially the areas of tuberosities or labial sulcus.
Causes
Insufficient material in tray
Failure to mold
Failure to pull upper lip out and upwards
Insufficient pressure
4. Tray flange showing through composition
Causes
Poorly selected or adapted tray
Incorrect centering of tray
Most of these deficiencies can be corrected by addition
of small amounts of composition.
28.
29.
30. FAULTS IN LOWER PRIMARY IMPRESSIONS
1. Insufficient depth, in the posterior lingual pouch
Causes
Flange of the tray short in this region
Lack of composition in the tray
To little force used in seating the tray
Tongue trapped by the tray flanges because the patient
failed to raise the tongue as the tray was seated
In some cases it is necessary to push the compound into
the lingual pouch area with the fore-finger just before the
tray is finally seated.
31. 2. Insufficient depth in the lingual, labial and
buccal sulci.
Causes
Lack of impression material
Not seating the tray with sufficient pressure
The presence of a smooth hollow in the buccal distal
peripheral
Causes
The cheek was not released from beneath the
composition border during functional trimming.
32. 3.Edge of the tray showing through the impression
Causes
Incorrect centering of the tray before seating.
In the anterior lingual region. The forward thrust of the
tongue not being countered by sufficient backward
pressure on the tray
Use of too large a tray for the mouth or failure to trim the
flanges adequately.
33. Corrections to faults (1) and (2 may be made by adding small
softened pieces of composition to the imperfect areas and
then reseating and re-molding the impression.
The error due to cheek folds, (3) should be corrected by reheating the impression in that area and re-adapting, whilst
fault number (4) usually requires an entirely new impression.
