12. ADVANTAGES OF DIGITAL DENTISTRY
1. Patient engagement.
It’s possible to present the final result to a patient even
before treatment starts .
engage in dialogue with them around their expectations, and adjust the
plan based on their wishes regarding the esthetics and the treatment
timeline.
13. 2. More accurate treatment planning:
Software solutions for dental treatment planning enable designing and
planning with digital precision and accuracy, which is a good way to
minimize errors .
14. 3. Time-saving:
Digital solutions allow dentists to take impressions quicker and give
patients the option to get treatment in a single visit, with less chair-time
for the patient. As for the labs, digital dental technologies speed up
processes, which lets them handle more orders in the same amount of
time.
15. 4.Space-saving :
With digital impression technology clinics can store all models on a
single computer, server or in the cloud, thus freeing up an entire room
that can be used for other purposes!
16. 5. Cost-effectiveness:
Dentists can save money on impression materials and transport by
taking them digitally instead.
6. No more gag-reflex:
Dentists taking traditional impressions are often faced with the patients’
gag-reflex or teeth hypersensitivity to cold washing agents. The
discomfort of conventional impression taking can be avoided by taking
impressions digitally.
17. 7.Entertainment:
Digital pediatric dentistry can help children experience dental
procedures as less stressful. Their 3D image on screen — looking like
a video game — helps them understand what’s happening.

18. History of digital dentistry
The history of digital dentistry can be traced back to the 1970s, when
the first computerized tomography (CT) scanners were introduced
This technology allowed for more accurate and detailed imaging of the
teeth and jaw and helped to improve diagnosis and treatment planning.
19. Later, in the 1980s, the first CAD/CAM system was introduced for
dental restorations allowing the computer-aided design of dental
restorations, which could then be milled out of a block of material using
a CAM system.
20. On the other hand, the first 3D printer for dental uses was introduced in
the 1990s and since then, 3D printing technology has advanced
rapidly, and is now widely used in dental practices for the design and
fabrication of crowns, bridges, and other restorations
21. one of the early pioneers of digital dentistry was CEREC (Chairside
Economical Restoration of Esthetic Ceramics), a system developed in
the early 1990s by German company Sirona
CEREC used digital imaging and CAD/CAM technology to create
custom restorations, such as crowns and bridges, in a single visit.
22. digital dentistry actually continued to evolve rapidly. Indeed, other
companies, such as 3Shape, Dentsply Sirona, and Align Technology, to
mention a few, developed advanced digital imaging and scanning
technologies, 3D printers, and software systems for virtual treatment
planning and simulation
23. Different categorization of digital system:
Intra oral scanner:
Intraoral scanning (IOS) is a newer technology widely used with
CAD/CAM for milling machines (subtractive technology) and 3D
printers (additive technology).
24. The procedure of IOS begins by taking a direct optical/digital
measurement of the patient's teeth or gums. This creates a 3D picture
of the surface topography of the target teeth and the gingival contours,
the antagonistic tooth/teeth, and/or the state of the dental occlusion
25. The IOS method has both advantages and disadvantages.
The major disadvantages most commonly mentioned are its purchase
and the management costs and the operator error of inexperienced
individuals.
On the other hand,
the main advantages of IOS are reduction in patient discomfort, time
efficiency, simplicity of operative steps, and the feasibility of better
communication amongst the dentist, dental technician, and patients,
particularly in distant locations.
26. How do intraoral scanners work?
An intraoral scanner consists of a handheld camera wand, a computer,
and software.
The small, smooth wand is connected to a computer that runs custom
software that processes the digital data sensed by the camera. The
smaller the scanning wand, the more flexible it is in reaching deep into
the oral area to capture accurate and precise data
27. The dentist can view the real-time images on the computer, which can
be magnified and manipulated to enhance details.
The data will be transmitted to labs to fabricate any needed appliances.
With this instant feedback, the whole process will be more efficient,
saving time and allowing dentists to diagnose more patients
28. dentists will insert the scanning wand into the patient's mouth and
gently move it over the surface area of the teeth.
The wand automatically captures the size and shape of each tooth. It
only takes a minute or two to scan
29. CAD/CAM TECHNOLOGY:
What is CAD/CAM dentistry?
CAD/CAM technology in dentistry is used to design and manufacture
dental restorations, such as splints, crowns, bridges, veneers,
inlays, and onlays. It streamlines the traditional workflows by reducing
the time and effort required to produce high-quality dental restorations
30. 1.The use of CAD/CAM in dentistry begins with a digital scan of the
patient’s teeth and oral structures.
2.The dentist uses an intraoral which are used to create a digital model.
Avant also accepts manual impressions scanner to capture precise 3D
images of the teeth and gums
31. 3.This digital model is then sent to a dental lab that typically uses
specialised CAD dental software to design the custom dental
restoration
32. 4. After the design is finalised and approved by the dentist, the CAD
software sends the design to a CAM machine – such as a dental milling
machine or 3D printer – that uses the information to manufacture the
dental restoration from a block of suitable material like ceramic, resin,
or metal.
33. What are the advantages of CAD/CAM in
dentistry?
• Precision and accuracy: Digital scanning reduces the
risk of errors and ensures a perfect fit for the restoration
• Enhanced patient experience: Digital dentistry
eliminates the use of traditional impression materials that
can be quite uncomfortable for patients.
• Superior aesthetics: CAD/CAM restorations can be
highly customized to closely match the patient’s natural
teeth
• Improved efficiency: Digital scans can typically be
completed faster than physical impressions, which means
less chair time and shorter appointments per patient.
34. 3D printing technology:
What Is Dental 3D Printing?
Dental 3D printing is the use of additive manufacturing to create dental
parts such as aligners, dentures, and crowns.
35. WhatAre the Dental 3D PrintingApplications?
1. Implants: 3D printers with high resolutions and printing accuracy
(e.g., SLA and DLP printers) are exceptional at printing complex
geometries like those associated with teeth.
2. Crowns and Bridges: Dental 3D printers can create precise
crowns and bridges of both fixed and removable varieties.
3. Surgical Guides: Dentists can use 3D printers to create surgical
guides for drilling and cutting. These guides assist dentists to make
surgery easier.
4. Anatomical Replicas and Models: Accurate anatomical replicas
of a patient’s mouth and jaws can be made with 3D printing.
36. Digital smile design:
What is digital smile designing?
DSD is a technical tool which is used to design and modify the smile of
patients digitally and help them to visualize it beforehand by creating
and presenting a digital mockup of their new smile design before the
treatment physically starts.
37. WHY DSD?
Clinical information, study models and photographs have been used to
establish a correct treatment plan for esthetic dentistry. Although these
data provide relevant information for diagnosis, they do not offer all the
information necessary for analysing the smile.
Dento-labial parameters vary according to lip dynamic, therefore a
posed smile differs from the smile in motion captured on video.
38. Virtual reality (VR)
Virtual reality (VR): utilizes advanced technologies to create virtual
environments (VE) that allow patients to be immersed in an interactive,
simulated world
These advanced systems interact at many levels with the VE,
stimulating sights, sounds, and motion to encourage immersion in the
virtual world to enhance distraction from pain
39. VR creates a super realistic 3D world using sights, sounds, and even
smells, helping patients escape from the real world. By giving patients
things to see and hear.
Some studies even suggest that VR can be a good alternative to
traditional pain relief methods, whereas another study has shown that
VR might be more effective than traditional pharmacological analgesia.
40. Digital occlusal analysis
Occlusal analysis allows the identification of normal and abnormal
occlusal contact points that alter the craniomandibular cervical system.
41. Example :
T-SCAN® is a computerized occlusal analysis system, which
accurately measures the occlusion (bite) of the teeth, along with other
aspects like bite force, location and timing.
The T-Scan is dentistry's only digital occlusal analysis system. This
dental scan device gives clinicians accurate 2D and 3D representations
of bite forces complete with timing information relative to dental
occlusion
42. Digital radiography
Digital radiography is a type of X-ray imaging that uses digital X-ray
sensors to replace traditional photographic X-ray film, producing
enhanced computer images of teeth, gums, and other oral structures
and conditions.
43. Digital dental images are acquired through three methods: the direct
method, indirect method and semi-indirect method.
The direct method uses an electronic sensor placed in the mouth to
record images.
The indirect technique uses an X-ray film scanner to view traditional
dental X-rays as digital images.
The semi-indirect digital technique combines a sensor and scanner to
convert dental X-rays into digital film.
44. Benefits of Digital Dental Radiography
Benefits of digital dental radiographs compared to traditional dental X-
rays include the following:
• Digital radiographs can be viewed instantly on any computer screen,
manipulated to enhance contrast and detail
• Early detection and treatment of dental problems can save time,
money and discomfort
• Digital micro-storage technology allows greater data storage capacity
on small, space-saving drives.
• Dental digital radiographs eliminate chemical processing and disposal
of hazardous wastes and lead foil, thereby presenting a “greener” and
eco-friendly alternative.
45. • Digital radiographs can be transferred easily to other dentists with
compatible computer technology, or photo printed for dentists without
compatible technology.
• Digital sensors and PSP (photostimulable phosphor) plates are more
sensitive to X-radiation and require 50 to 80 percent less radiation
than film. which promotes radiation safety.
• Digital radiograph features, including contrasting, colorizing, 3-D,
sharpness, flip, zoom.
• Digital radiographs reveal small hidden areas of decay between teeth
or below existing restorations (fillings),
46. Disadvantages of Digital Dental Radiographs:
• Digital radiograph start-up costs are expensive for dentists.
• Sensor size: Some direct systems sensors are thicker and bulkier
than dental films, causing patient discomfort, especially for those
prone to gagging.
• Infection control: Most digital sensors and PSP plates can’t be
sterilized and therefore require protective plastic barriers that must be
changed between patients to prevent cross contamination and
infection.
47. Recent Advanced Technologies
Artificial Intelligence
Applications of Artificial Intelligence in Various Fields of Dentistry:-
• Artificial Intelligence in Patient Management:-
Artificial intelligence based virtual dental assistants can perform several
tasks in the dental clinic with greater precision, fewer errors and less
manpower compared to humans
It can be used to coordinate appointments, managing insurance and
paperworks as well assisting clinical diagnosis or treatment planning.
48. Artificial intelligence in Diagnosis and Treatment:-
•
Artificial intelligence can be used as a useful modality in diagnosis
and treatment of lesions of oral cavity and can be employed in
screening and classifying suspicious altered mucosa undergoing
premalignant and malignant changes.
49. Artificial Intelligence in Oral and Maxillofacial Surgery:-
The greatest application of artificial intelligence in oral surgery is the
development of robotic surgery where human body motion and human
intelligence is simulated [18]. Successful clinical application in image
guided surgery in cranial area include oral implant surgery, removal of
tumor and foreign bodies, biopsy and TMJ surgery
50. Artificial Intelligence in Prosthetic Dentistry:-
In order to provide ideal esthetic prosthesis for the patient various
factors like anthropological calculations ,facial measurements, ethnicity
and patient preferences has been integrated by a design
assistant,RaPid for use in prosthodontics .RaPiD integrates computer
aided design
51. Teledentistry
• Teledentistry is a combination of telecommunications and dentistry
involving the exchange of clinical information and images over remote
distances for dental consultation and treatment planning. Teledentistry
has the ability to improve access to oral healthcare, improve the
delivery of oral healthcare, and lower its costs. It also has the
potential to eliminate the disparities in oral health care between rural
and urban communities.
52. METHODS OF TELECONSULTATION
Teleconsultation through teledentistry can take place in either of the
following ways – “Real-Time Consultation” and “Store-and Forward
Method”.
Real-Time Consultation involves a videoconference in which dental
professionals and their patients, at different locations, may see, hear,
and communicate with one another
Store-and-Forward Method involves the exchange of clinical
information and static images collected and stored by the dental
practitioner, who forwards them for consultation and treatment planning
the patient is not present during the “consultation
53. To create custom parts that match a patient’s anatomy, dental providers
use a tool called an intraoral scanner.
This creates images of a patient's teeth and records them in the form of
a CAD file. Dentists then use this CAD file to create implants or dental
molds through 3D
