A new CAD/CAM-based procedure has the potential to revolutionize the way complete dentures are manufactured.
The term "Digital Denture" describes an integrated manufacturing process for CAD/CAM-based complete denture prosthetics. The Digital Denture process was presented to the public for the first time at IDS 2015. Key elements of this process include innovative devices, software programs and coordinated materials geared towards the needs of dental technicians and clinicians. Especially designed software programs streamline complex working steps, i.e. the setup of denture teeth. Digital Denture results in accurately fitting CAD/CAM denture bases and reduces the active working time required for accomplishing complete dentures.

Rough composite fillings scatter more light thus appear opequewhere as smooth highly polished filling do not.
Esthetics play a very important role in modern dental treatment. The ideal restorative material should match the color of the tooth it restores. In maxillofacial prosthetics the color of the gums,
external skin and the eyes have to be duplicated. Clinically in the operatory or dental lab, color selection is usually done by the use of shade guides.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

orderly numeric system of color description that
is still the standard today. In this system color is
divided into three parameters:
-Hue
-Chroma
-Value.

22. Anatomy of smile:Anatomy of smile:
Most people feel they can recognize an attractive
smile ,but individual opinion will vary, particularly
when cultural factors are considered. In general,
an extensive smile that showed the complete
outline of maxillary anterior teeth and teeth
posterior to the first molar was considered most
attractive and youthful. In smiles that were
considered the most attractive, the incisal edges
of the maxillary teeth were parallel to the lower lip.
www.indiandentalacademy.comwww.indiandentalacademy.com
23. ProportionProportion::
-Esthetics depends largely on proportion. An object is
considered beautiful if it is properly proportioned, and is
unattractive if it is top-heavy, squat, or out of proportion.
-Their growth is closely related to mathematical
progression called (Fibonacci series) in which each
number is the sum of two immediately preceding it :
0,1,1,2,3,5,8,13,21,34,55,89, and so on (n1+n2 = n3).
www.indiandentalacademy.comwww.indiandentalacademy.com
24. The ratio between succeeding terms converges
approximately 1.618 to 1 known as golden proportion.
When a line is bisected in the golden proportion, the ratio
of smaller section to the larger section is the same as the
ratio of the larger section to the whole line. A harmony
exists in the smile when the golden proportion exists
between the maxillary central incisor and the lateral
incisor as well as the lateral incisor and the canine .
www.indiandentalacademy.comwww.indiandentalacademy.com
26. Application of sizing the central incisors from
certain facial measurements is known as 1 to 16
theory, whereby the height of an ideal maxillary
central incisor from the incisal edge to the gingival
crest is 1/16th
of distance from inferior border of the
chin to the inter-pupillary line. The same tooth
width can be measured from the mesial to distal
contact areas and is 1/16th
of the distance
measured from either zygometic prominence
through an imaginary facial midline.
www.indiandentalacademy.comwww.indiandentalacademy.com
27. Balance:Balance:
Balance, including the location of the midline is an
important prosthodontic concept. The observer expects
the left and right side of the mouth to balance out, if not
to match precisely.
An obvious restoration on one side may be balanced if
there is a diastema or a large tooth on the other side. A
balanced arrangement implies stability and permanence.
www.indiandentalacademy.comwww.indiandentalacademy.com
28. MidlineMidline
-Coincidence of facial and incisal midline is stressed
when assessing orthodontic treatment planning and
should be carefully evaluated when treatment –planning
prosthodontics.
-Studies have shown that mean threshold for acceptable
dental midline deviation is 2.2-1.5 mm.

laminates:
Tooth preparation will depend on the existing color
of the teeth , whether change in alignment or an
increase in height of the final restoration is sought.
When a mild or moderate discoloration has to be

44. Shade selection:Shade selection:
To provide the patient with esthetic restoration ,the
dentist must consider the scientific basis of color as well
as the artistic aspects of the shade selection.
Considerable variation exists among dentists, some
dentists are unable to duplicate even their own shade
selection from one patient to the next. Shade selection
can be improved by applying the principle of light and
color and dental ceramics techniques.
www.indiandentalacademy.comwww.indiandentalacademy.com
45. Shade selection sequence:Shade selection sequence:
There are few simple guide lines to be followed by
practitioners;
-Use the shade guide that matches the porcelain your
technician is using.
-The shade should be matched prior to preparation of the
tooth to be restored.
-Ask the patient to remove all distractions before
attempting to match a shade, such as lipstick, earings,
glasses, and heavy facial makeup.

50. Vitapan 3D master shade guide:Vitapan 3D master shade guide:
The shade samples are grouped in six light
variation in evenly spaced steps. The shade
guide is spaced in steps of 4 CIELAB units in
lightness dimension and 2 CIELAB units in the
hue & chroma dimensions. The manufacturer
recommends selecting the lightness level first
with this system and then selecting the chroma
or saturation and finally the hue.

52. Shade distribution chart:Shade distribution chart:
Shade distribution charting is a practical approach
to accurate shade selection and is recommended
even when a fairly good match is available from
the commercial shade sample. The tooth is
divided into three region: cervical, middle and
incisal. Each region is matched independently
either to the corresponding area of a commercial
shade sample or to a single color porcelain chip.
Because only single color is matched intermediate

55. Esthetics and Periodontics:Esthetics and Periodontics:
Periodontal therapy plays an important role in
esthetics through the introduction of new surgical
techniques and the adaptation of traditional
periodontal procedures. In addition, the recognition
of the etiology and complicating factors underlying an
esthetic periodontal problem is crucial .
The periodontal defects posing an esthetic problem
can be addressed once the patient is adequately
motivated in periodontal health, maintenance and
efficient plaque control.
www.indiandentalacademy.comwww.indiandentalacademy.com
56. These defects may include:These defects may include:
1) Violation of biological width.
2) Gingival asymmetries
3) Abnormal frena
4) Excessive gingival display.
5) Deficient pontic areas.
www.indiandentalacademy.comwww.indiandentalacademy.com
57. Biologic width:Biologic width:
Interference drawn from autopsy recording suggests that
the mean sulcus depth is 0.69mm, mean length of
junctional epithelium is 0.97mm and connective tissue
attachment is 1.07mm. The combined width of the latter
two is 2.04mm and is referred to as biologic width. This
biologic width is always maintained between the tooth
and periodontal apparatus, violation of which would lead
to gingival inflammation and bleeding resulting in
recession and/or pocket formation.
www.indiandentalacademy.comwww.indiandentalacademy.com
58. Crown lengthening:Crown lengthening:
In cases of single tooth gingival asymmetry
where crown lengthening with minimal osseous
reduction is indicated, where in after the
gingivectomy is carried out, two vertical
incisions are made on the gingival margins
without involving the interdental papilla .
After the raising the flap the osseous reduction is
carried out. While contouring the bone, care
should be taken to avoid any ledge formation in
the bone crest.
www.indiandentalacademy.comwww.indiandentalacademy.com
60. Abnormal frenal attachment:Abnormal frenal attachment:
The maxillary frenum may cause esthetic problems,
especially in cases of gingival smiles. The frenum can
also cause a pulling force on the gingival margin, in
some cases leading to gingival inflammation and
progressive recession of gingiva.
A resection (frenectomy) or a repositioning
(frenotomy) may be necessary. When the esthetics is
the only factor then a frenotomy may be necessary to
give the desired result.
www.indiandentalacademy.comwww.indiandentalacademy.com
61. Pontic design:Pontic design:
Pontics are the artificial teeth of a fixed partial denture
that replace missing natural teeth restoring function and
appearance. The pontic as it mechanically unites the
abutment teeth and covers a portion of the residual ridge,
assumes a dynamic role as a component of the prosthesis
and cannot be considered as a life less insert of gold,
porcelain or acrylic.
www.indiandentalacademy.comwww.indiandentalacademy.com
62. Residual ridge contour:Residual ridge contour:
An ideally shaped ridge has a smooth, regular surface of
attached gingiva , which facilitates maintenance of
plaque free environment . Its height and width should
allow placement of a pontic that appears to emerge from
the ridge and mimics the appearance of the neighboring
teeth. Loss of residual ridge contour lead to unaesthetic
open gingival embrasures, food impaction and
percolation of saliva during speech.
www.indiandentalacademy.comwww.indiandentalacademy.com
63. Siebert classified residual ridge deformities into three
categories.
Class 1 : Facio lingual loss of tissue width with normal
ridge height.
Class2 : Loss of ridge height with normal ridge width.
Class3 : A combination of loss in both dimension.
www.indiandentalacademy.comwww.indiandentalacademy.com
64. Prosthetic gingiva:
When interdental spaces are of concern and no cosmetic
prosthetic work is anticipated, artificial gingiva is an
option. A border molded impression is made of the
involved area. The laboratory fabricates a gingival
veneer of pink denture acrylic, with the apical extent in
the mucobucal fold and the coronal extent restoring a
normal free gingival margin appearance.
