Digital Dentistry refers to a digital
workflow process involving
• the use of 3D Computed Tomography
(CT) scanner,
• 3D treatment planning software,
• 3D Printer,
• 3D intra-oral scanner and
Computer-Aided Design/Computer-
Aided Manufacturing (CAD/CAM)
technology in the field of dentistry.
BENEFITS OF DIGITAL
DENTISTRY
• Allows for more comprehensive pre-
surgery treatment planning so that all
difficult and critical decisions can be
made before surgery
• Reduces guess work and human errors
• Accuracy is improved, e.g. dentists can
decide on the length of implant and
angle of insertion
• Therefore surgery is safer and more
efficient
• Reduces time of treatment/surgery,
which means that the period of time
when patient’s anxiety is high, is reduced
• Minimize post-surgery complications
• Less waiting time for surgery
appointments, especially when seeing
specialists (usually up to 2 months
waiting period.
APPLICATIONS OF DIGITAL
DENTISTRY
• Implant dentistry
• Reduces storage space because
teeth and jaw models can be
scanned and archived digitally
rather than having to store
physical copies
• Create Temporomandibular
(TM) Joint models for
accurately diagnosing and
consulting patients with TM
disorders
• Creating mouth guards, stents
and splints

2. WHY IS THERE
A NEED FOR 3D
SOFTWARE?
• A traditional CT scan comes in a 2D
physical film and as such the
surgeon is unable to plan and
visualize the placement of a dental
implant prior to the actual surgery.
• 3D software is necessary because it
aids in pre-treatment planning to
digitally place the implants.
• This planning will reveals the type
and size of dental implants suitable
for the patient and the exact angle
and orientation of the dental
implant. This allows surgeries to be
efficient without the need to make
last minute decisions
HOW DOES 3D
PRINTING HELP
DENTISTRY?
• Even with a 3D scan and 3D
treatment planning, it still takes the
expertise of the surgeon to place the
dental implant accurately by
freehand.
• Currently, most surgeons utilize a
digital bite-wing X-ray and a drilling
guide to test the angle and direction
of the placement before inserting
the actual dental implant to avoid
nerves and adjacent teeth as
planned.
• By printing a physical dental implant
stent or guide, the surgeon is able to
place the dental implant with pin-
point accuracy thereby eliminating
trial and error. This ultimately also
makes the surgery efficient, safer
and reduces its duration.
WHAT'S THE DIFFERENCE
BETWEEN
DIGITAL DENTISTRY AND
NORMAL DENTISTRY
• Take for example, in the case of dental
implants, diagnosis of dental implant
surgery was done without a 3D cone
beam CT scan and usually only with a
2D X-ray scan.
• This is insufficient to appreciate jaw
bone density and therefore surgeons
only find out whether the patient has
sufficient bone to support the dental
implant during surgery. This inevitably
corners the patient to make a hasty
decision to proceed with bone grafting
or to abort the surgery altogether.
• Currently for single tooth implants,
surgery is usually done without a guide.
• A digital periapical x-ray is used during
surgery to check the angle and depth of
the drill before an actual implant is
inserted.
• For multiple implants, a guide is highly
recommended to ensure accurate
implant placements.
DIGITAL DENTISTRY
IS A REVOLUTION IN
THE INDUSTRY.
• Digital dentistry is a way
of using computers,
scanners, cameras, video
recordings, 3D printers
and sometimes virtual
reality with specific
software programs to
improve the diagnosis and
treatment of oral
conditions in one’s mouth.
• Digital Dentistry allows us
to make mistakes on the
computer, so they do not
occur in our patients’
mouths.
1) CAD/CAM
2) 3D Printing
DISADVANTAGES OF
CAD/CAM
1. The initial cost of the
equipment and software is
high.
2. The practitioner needs to
spend time and money on
training.
3. Large amount of raw
material is wasted because of
unused portions of the mono-
blocks.
ADVANTAGES OF
CAD/CAM
1. Speed.
2. Ease of use
3. Quality.
4. Digital scans have the
potential to be faster and
easier than conventional
impressions
5. No second appointment.
6. No provisional restorations.
7. Scans can be stored on the
computer
• 1985 is the key year to the introduction of
CAD/CAM technology in dentistry.
CAD: Computer
Aided Design
CAM: Computer
Aided Manufacturer
• The CAD/CAM systems are classified into:
1. Laboratory systems
2. Chairside systems
PART 2
Digital impressions can be taken using an
intra-oral scanner – much like a camera
which measures light reflection times.
The data is processed using an algorithm
and displayed as a 3D model on a screen.
Some systems require individual images,
whilst others require video.
The digital impression can then be used
to manufacture the prosthesis using 3D
printers.

3. How 3D Printing is Changing How Dental Implants
are Placed?
A prime example lies in 3D printing; a revolutionary
change is how certain dental implants are placed. we are
pleased to be on the cutting edge of this technology and
have acquired a 3D printer (in addition to cone beam x-ray
machine) to assist in the process of dental implants.
WHAT DOES A 3D PRINTER DO?
The power of 3D printing technology is the ability to take a
broad range of data that is collected from X-ray and other
imaging, and recreate the object from scratch. The
"printed" item is fabricated through a process of
combining small layers together, which is what builds up
the finished piece. In this way, 3D printing is a fabrication
method that is highly accurate, yet far faster than
traditional manufacturing methods.
HOW CAN 3D
PRINTING BE
APPLIED TO
DENTAL
IMPLANTS?
The process of creating
and placing a dental
implant involves numerous
steps. One of those steps
is creating a surgical guide
that will fit over the
patient's existing teeth and
gums. doctors are able to
use data collected from a
cone beam x-ray to pre-
plan the exact location of
your future dental.
Definition
3D printing is also known as :
Additive manufacturing ,
Layered manufacturing ,
It is the process in which
multiple layers of material are
added one by one under
computer control to create
three-dimensional object .
PART 3
It all starts with creation of a virtual
design(CAD) of the object.
The most common and universal file formats for
3D printing are STL and VRML.
Scanner may be used to produce a 3D model.
The 3D model is sliced and then it is ready to
feed into the 3D printer of compatible brand and
type.
The 3D printer reads every slice (2D image) and
creates a three dimensional object.
In 1984, Charles
Hull an American
Engineer, developed the
world’s first working 3-D
printer .
Materials used
Metals like silver, steel,
titanium.
Resins like PLA, polyamide
(nylon), glass filled polyamide,
epoxy resins, photopolymers,
polycarbonate.
Organic materials such as
cells, wood, and chocolate
Surgical Guides
Dental drilling requires a high degree of precision as hitting the
wrong nerve at best results in a high degree of discomfort for the
patient and at worst can cause partial facial paralysis. Such is the
necessity of highly trained and experienced surgeons.
Full-Arch Surgical
Guides
Full-arch surgical guides are
ideal for multi-site, single/dual
arch, tooth, bone and mucosa
supported guide creation for the
clinical placement of dental
implants.
Quadrant Surgical
Guides
Quadrant surgical guides are
ideal for single-site, single-arch,
tooth-supported guide creation
for the clinical placement of
dental implants.
PART 4
Implant Planning Software Is Based On
Three Principles: Intended Final Restoration,
Available Bone And The Overall Clinical
Situation.

WHAT YOU WILL
GET?
Here Are The Main Advantages Of 3D Printing And
3D Scanning For The Dental Industry:
Cost effective Digital manufacturing is a very cost-efficient
approach for dental labs.
Simpler workflow Moving to digital dentistry using 3D scanning and
3D printing greatly reduces the amount of manual work and labor
intensive tasks
High-quality parts one of the most important thing: 3D scanning
and 3D printing allow to improve greatly the efficiency without
compromising on the quality of the end products.
Short turnarounds When it can take 2-3 weeks to produce a dental
crown with conventional methods, using 3D scanning and 3D
printing can bring this number down to 2-3days.
Improved patient experience The combined use of 3D scanning and
3D printing by dentists allows to produce custom dental appliances
in short amounts of time, thus increasing treatment efficiency and
patient comfort.
