4. Microsurgery
• Defined as a refinement in surgical technique by
which visual acuity is increased using a
microscope at magnifications exceeding 10x.
• Microsurgery is also an ergonomic methodology
in which surgical manipulations are improved
through better motor coordination.
6. Magnifying Loupes
• Dual monocular telescopes with side-by-side
lenses.
• Image formed : Stereoscopic properties.
• Principle : Convergent optical lens
• System : Keplerian optical system
7.
8. Simple Loupes
• Pair of Single Meniscus lenses.
• Limited Capabilities.
• Primitive magnifiers.
• Magnification can only be
increased by increasing lens
diameter.
• Disadvantage : Magnification
only 1.5x
9. Compound Loupes
• Multi-elemental lenses with intervening air
spaces to gain additional refracting surfaces.
• Advantage : Increased magnification with more
favourable working distance and depth of field.
• Disadvantages : Magnification not more than
3.5x.

12. Prism Telescopic Loupes
• Highly advanced Loupes.
• Produce better magnification, wider depths of field, longer
working distances, and larger fields of view than any other
types of Loupes.
• Prisms used : Schmidt or ‘Rooftop’ prisms; barrel of the
prism can be mounted on any eye-glass frames.
• Magnification : Above 4x
16. For practical use in periodontics, the
surgical microscope must have :
1.Manoeuvrability
2.Stability
3.Side Mounted Illumination

21. Periodontal Microsurgery
Periodontal microsurgery introduces the potential for a less
invasive surgical approach in periodontics.
This includes :
1.Root preparations
2.Surgery under Magnification
3.Microsurgical Instruments
4.Ergonomics (hand & Body Postures)
5.LASERS in Dentistry
