Laser technology has several applications in dental laboratories and prosthodontics. Lasers are used in 3D scanners to scan dental impressions and structures via triangulation or confocal scanning. Digital data from scans can be used to print 3D casts or mill restorations using additive manufacturing techniques like 3D printing or laser sintering of powdered materials layer-by-layer. Lasers are also used in welding techniques like laser deposition or laser sintering of metal alloys to fabricate dental frameworks and prostheses.

Dentistry in the digital age
Digital dentistry refers to the use of dental technologies or devices to carry out dental procedures rather than using mechanical or electrical tools. The use of digital dentistry can make carrying out dental procedures more efficient than using mechanical tools, both for restorative as diagnostic purposes. 'Godfather' of Digital Dentistry is the French professor François Duret, who invented dental CAD/CAM in 1973.

Coherent, Whitepaper: LAM - Laser Additive Manufacturing with new laser power...Dirk Grebert
Novel Beam Diagnostics Improve Laser Additive Manufacturing.
Laser additive manufacturing (LAM) is rapidly becoming an important method for the fabrication
of both prototype and production metal parts.
Now, a novel system from Haas Laser Technologies addresses both these issues. It can deliver
very rapid measurements of beam mode, and nearly instantaneous power for both CW and
pulsed, high power lasers using PowerMax™-Pro sensing technology from Coherent.
Novel Coherent PowerMax-Pro sensor technology:
"Measure One Million Times Faster!"
In order to directly measure beam power, which is critical for the system to accurately calculate
laser power density at the precise location the powder layer is being processed, the system
incorporates a Coherent PowerMax-Pro detector. This utilizes a relatively new type of detector
technology called a transverse thermoelectric (Patent #9,059,346), first introduced to the market
in 2014, which combines the broad wavelength sensitivity, dynamic range and laser damage
resistance of a thermopile with the response speed of a semiconductor photodiode (see
side bar).
Revolutionary:
50mW up to 6kW, every pulse > 10µs, at full power!
YOUR Benefits:
Increase yield, save time and costs, enhance production throughput.

From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
2. 1- laser optical laboratory scanners(
laser is used as a light source)
• laser scanner: is a 3D scanner measuring the distance
to an object surface by triangulation mechanism
• Most dental optical scanners are triangulation or
confocal scanners. In case of triangulation, a light
source, typically a laser, shines onto an object and its
reflection is captured by a sensor that is positioned
slightly off-angle to the angle of the incident light. As
the next laser beam is reflected by an adjacent location
at a different distance to the light source, it is recorded
in a different location on the sensor array. It is this
difference that is used to compute the difference in
distance to the original source, and by inference the
topography of the surface being scanned.

6. 2- Resin polymerization of 3D printed
casts.
• Virtual casts may be generated from data
captured directly intraorally or by a scan of a
solid model of the dentition obtained through a
conventional impression technique in the dental
laboratory with a laboratory scanner.
• These digital data can be used to generate solid
working casts by an additive process in which
incremental layers of resin are
polymerized by a laser.

7. CAM(computer aided manufacturing
• CAM refers to the use of computer software to program
the machinery that is responsible for the milling or
printing of intermediate and final restorations.
• CAM is separate from the actual design of restorations—it
is the communication between the CAD software and the
milling units. This involves the selection of where on the
block of material a crown should be milled, how thick the
layers of wax should be during wax printing, and so on.
• CAM manufacturing techniques are:-
• subtractive.
• Additive.
• Combination(subtractive then additive).

9. 3-New Technologies for Base Metal Alloys
(laser deposition or LENS technology)
• Optomec (http://www.optomec.com) developed laser deposition, or
LENS (laser-engineered net shaping), technology in which a high-power
laser in an argon environment is used for melting elemental or alloy
powders, which are directed onto a small area of a substrate through
special nozzles to build up, layer by layer, a complex part in a raster
(horizontal lines)pattern.
• This technique enables functionally graded titanium alloy compositions
to be created with controlled microstructures and mechanical
properties for orthopedic applications. However,
further development of the LENS system is needed for clinical usage in
prosthodontics, because dental restorations are much smaller than
orthopedic implants.

10. Definitions
• Selective laser melting: SLM; an additive CAM continuous
layering buildup process in which elemental metal or alloy
powder deposition is closely followed by laser melting to
create a finished shape under computer control.
• Selective laser sintering: SLS; an additive CAM technique by
sintering plastics, glass, or ceramics into 3D structures.
• generally sintering means densification.
• But in PFM RESTORATIONS, Sintering is the process of firing
the compacted ceramic powder at high temperature to
ensure optimal densification. This occurs by pore
elimination and viscous flow when the firing temperature is
reached.

11. • In laser sintering/melting dental technology, developed
by several companies (BEGO, Phenix Systems and
Heraeus Kulzer), a high power laser is used to
selectively fuse particles lying on a powder bed and
build a complex part layer by layer.
• This is used with Biocompatible Co-Cr alloys, titanium
and a gold-platinum alloys.
• As a result of further developments in laser sintering,
this technology may replace the dental casting
technology that has served the profession well for the
past century.

12. 5- Laser sintering of dry milled partially
sintered Co-Cr alloy blanks
• Amann Girrbach (well known dental
manufacturing company, AG) introduced Ceramill
Sintron partially sintered Co-Cr alloy blanks that
can be readily dry-milled by means of a milling
machine and subsequently final sintered in a
special furnace with an argon atmosphere.
• Both the milling machine and the furnace can be
obtained from the manufacturer, which claims
that the process yields restorations and
frameworks with homogeneous and distortion-
free structures.

13. 6- Laser Welding (e.g:- laser star and I -
weld laser welding devices
• Laser welding is the joining of metal components through the
use of heat generated with a laser beam.
• Laser assembly of FDPs has been reported to have higher
strength and reduced corrosion in comparison with
conventional soldering, although laser-welded connectors
seem as susceptible to fatigue failure and may be less suitable
for joining noble-metal alloys than for base-metal alloys. Laser
welding is a practical way to join cast or milled titanium or
cobalt-chromium components (i.e., if these are to be used for
implant-supported prosthesis frameworks).
• RIGID CONNECTORS, Rigid connections in metal can be made
by casting, milling, laser sintering, soldering, or welding.

14. • Manual laser welding systems are an essential tool for today's
modern dental laboratory. An excellent alternative to
conventional soldering procedures, manual laser welding
systems assist dental laboratory technicians in fabrication and
reconstructive repair procedures, including new cast clasp
assembly, loops and posts for tooth additions, cast extensions
for existing partials, new wrought wire single-arm clasping, as
well as many other common laboratory welding services. The
state-of-the-art, free-moving concept allows operators to
benefit from pin-point accuracy and localized heat, which
produces excellent seam welds and eliminates thermal
expansion on passive fit bridgework, implant bars and frames,
and other common dental prosthetic connections. E.g:-
LaserStar welding systems are suitable for most dental alloys
including titanium.
