Introduction
CERAMICS : An inorganic compound with non-metallic prosthesis typically consisting of oxygen and one or more metallic or semi-metallic elements that is formulated to produce the whole part of a ceramic based dental prosthesis. – GPT 7.
The word Ceramic is derived from the Greek word “keramos”, which literally means ‘burnt stuff’, but which has come to mean more specifically a material produced by burning or firing.

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

RMD24 | Debunking the non-endemic revenue myth Marvin Vacquier Droop | First ...BBPMedia1
Marvin neemt je in deze presentatie mee in de voordelen van non-endemic advertising op retail media netwerken. Hij brengt ook de uitdagingen in beeld die de markt op dit moment heeft op het gebied van retail media voor niet-leveranciers.
Retail media wordt gezien als het nieuwe advertising-medium en ook mediabureaus richten massaal retail media-afdelingen op. Merken die niet in de betreffende winkel liggen staan ook nog niet in de rij om op de retail media netwerken te adverteren. Marvin belicht de uitdagingen die er zijn om echt aansluiting te vinden op die markt van non-endemic advertising.
2. DEFINITIONS
• Ceramic –
• An inorganic compound w/ non metallic
properties typically composed of metallic and
non metallic elements
• Dental ceramic –
• An inorganic compound w/ non metallic
properties typically composed of O2 and 1 or
more metallic or semi metallic elements that is
formulated to produce the whole part of a
ceramic based dental prosthesis
6. Non oxide Ceramics
• Impractical for dental use
• Why?
• High sintering temp
• Unesthetic color
• opacity
7. Glass Ceramics
• Are partially crystallized glass
• Produced by nucleation and growth of crystals
in glass matrix phase
8. Dental ceramics
• May consist primarily of :
• Glasses , glass ceramics or highly crystalline
structures
• Ceramics are more resistant to corrosion than
plastic
• Remain stable for a long period of time
• Do not react with most liquids, gases
• Excellent – fair fracture toughness
• Zirconium dioxide
> Flexural strength similar to steel
9. Dental ceramics
• Biocompatible
• Long term color stabbility
• Wear resistance
• Ability to be formed into precise shapes
11. Dental ceramics can be classified
according to :
• Use or Indication
- Anterior
- Posterior
- Crowns
- Veneers
- Post and cores
- FPDs
- Stain ceramics
- Glaze ceramics
12. • Composition
- Pure alumina
- Pure zirconia
- Silica glass
- Leucite-based glass ceramic
- Lithia based glass ceramic
18. Metal Ceramic Prosthesis
• COMPOSITION OF DENTAL PORCELAINS
• Most dental porcelains consist of
• Kaolin
• Silica
• Feldspar
• Glasses
19.
20. Glass modifiers
• Manufacturers employ glass modifiers to
produce dental porcelains with different firing
temperatures
Categories Firing temperature
High fusing 1300oC or above
Medium fusing 1101 to 1300oC
Low fusing 850 to 1100oC
Ultra low fusing < 850oC
21. Feldspathic Porcelains
• Feldspar- main ingredient of classical metal
ceramic porcelain. ( crystalline and opaque)
• Chemically designated as K2O.Al2O3.6SiO2
• These ceramics are called porcelains because
they contain a glass matrix and one or more
crystal phases.
22. Other Additives
• B2O3 ( Boric Acid) – behaves like a glass modifier
• Alumina – not a true glass modifier but can alter
softening temperature and viscosity
• Pigmenting oxides – natural shade of tooth
• Iron or nickel oxide – brown
• Copper oxide – green
• Titanium dioxide – yellowish brown
• Manganese oxide – lavander
• Cobalt oxide – blue
• Opacity– zirconium oxide, tin oxide
23. Esthetic potetial
Metal ceramic All Ceramic
• 70% of all fixed restorations • Matches appearance of
• Not the best esthetic choice adjacent natural tooth
• Dark line at facial margin • More susceptible to
fracture
• Ceramic margin
24. Porcelain Condensation
• Supplied as a fine powder to be mixed with water
or another vehicle and condensed into desired
form
• Dense packing has 2 benefits:
1. Lower firing range
2. Less porosity
• Packing may be achieved through
1. Vibration
2. Spatulation
3. Brush technique
25. Drying
• The restoration is placed in an open furnace to
be dried.
• Until 480 deg C is reached
• Drying stage – 5- 8 minutes
• Ensures the remaining water is removed
• Dries too quickly – spontaneous breakage
• If wet structure is placed onto firing in hot
furnace – steam-crumble-explode
26. Sintering of porcelain
• The purpose of firing :
• To sinter the particles of powder together
properly to form the prosthesis.
• Sintering – process of heating closely packed
particles to a specified temp to densify and
strengthen a structure
• After porcelain is preheated, firing cycle is
initiated.
27. Overglazing and shading
• Natural glazed porcelain is much stronger than
ground, rough, non glazed porcelain.
• Glaze – effective in reducing crack propagation
within the outer surface.
• Stains and glazes
28. Cooling of metal-ceramic prosthesis
• Sudden changes in temperature – fracture
• Slow cooling followed by slow opening of
furnace door
29. Benefits and drawbacks of metla
ceramics
• Stronger and more durable than all ceramic
crowns
• Permanent aesthetic quality
• Fracture resistance
• No abrasion wear
• No staining along metal and veneer interface
• Less tooth structure is removed to provide
proper bulk for the crown.
30. Ceramics for Ceramic Metal
Restorations
• 5 requirements:
1. Must simulate appearance of tooth
2. Fuse at low temp
3. Must have compatible thermal expansion
with metals
4. Must withstand oral environment
5. Must not abrade opposing teeth
31. Ceramics for ceramic metal
restorations
• Ceramics are composed of crystalline phases
in an amorphous , glassy vitreous matrix.
• Glass
• They fuse at a lower temp , to prevent metal
from distorting
35. • Ceramics are the best materials to match
esthetic complexity of human teeth
• Used for ceramic metal crown
• FPD
• All ceramic resto
• To fabricate denture teeth
36. Ceramic metal crowns
• ADVANTAGE:
• Better abrasion resistance
• More durable
• Better adhesion with resin cements
• DISADVANTAGES:
• Occlusal adjustment is more difficult
• Not for high stress areas
37. All Ceramic Crowns, inlays , veneers
• Ceramic veneer – layer of ceramic bonded to
the facial surface of a prepared tooth to cover
any defaults.
• Custom made , fabricated in lab.
Editor's Notes
