This is a series of videos, recorded as a workshop with Dr. Alessandro Conti and Davide Bertazzo, providing insights into the use of microscopes and magnification in restorative dentistry with demonstrations on adhesive indirect and direct restorations.

Introduction to microscope dentistry

Aims and objectives :

  • Understand the optical characteristics and how microscopic vision works with the operators vision

  • How the eyes accommodate to focus on the retina
  • The reasons for eye strain and the symptoms
  • How microscopes allow for improvement in these symptoms
  • Understand the benefits of microscopes over loupes
  • Understand loupes and the difference between Prismatic and Galilean loupes
  • The differences between operative and diagnostic microscopes
  • Gain some tips on how to adjust your microscope and its elements such as the eye piece, to get the correct vision, setting inter-pupillary distance
  • Gain some tips on how to get the best focus on the microscope, and the best patient and clinician positioning

Microscope dentistry, posture, clinical applications and working position

Aims and objectives:

In this video you will learn:

  • Tips on posture and positioning
  • Clinical situations where the microscope can be used, with live examples – diagnosis, hygienist, direct and indirect restorative work, prosthodontics and surgical
  • Working positions for each arch

Tooth preparation - refining tooth preparation margins

Aims and objectives:

  • Demonstration of how he refines a tooth preparation in order to move the tooth margin

Tooth preparation - an anterior tooth

Aims and objectives: 

  • Learn the preparation steps to ensure smooth margins for an incisal fracture
  • The preparation steps for a posterior onlay cavity

Rubber dam - demonstration

Aims and objectives: 

  • Understand how to best use rubber dam

  • How to achieve a good rubber dam position via a hands-on demonstration on a typodont model

Preparation of class IV cavities

Aims and objectives:

  • Preparation of class IV cavities – gain tips for maximum aesthetics

  • Understand different prep techniques for bevel, 45-degree chamfer and shoulder, and indications for each type of margin
  • Demonstration of cavity preparation of a class V cavity in an old restoration

Workflow of an indirect composite - preparation to lab to cementation

Aims and objectives:

  • Learn how to make an indirect onlay in composite
  • Demonstration of the preparation of the cavity and the core
  • How it is prepared in the lab
  • Adhesion technique

Composite stratification for a posterior cavity

Aims and objectives:

  • Gain an insight into how to build posterior composite, step by step, as a direct restoration
  • Understand the need for each step of the stratification
  • Tips on enamel and dentine build up for each aspect of the tooth - smooth surface, the passage and interproximally
  • The role of staining
  • Tips on the final finishing 

Cementation phases of an onlay

Aims and objectives:

  • Understand the steps for cementation of onlays
  • The importance of isolation and checking interproximal contacts
  • The sandblasting and the choice of the right sandblasting
  • Understand the step by step approach to ensure a good bond
  • How to place onlay cement, remove excess and achieve a final good result

Laboratory workflow using microscopes

Aims and objectives:

  • Understand the challenges within the dental laboratory workflow and how microscopy can help
  • Demonstration of procedures where microscopy is used
  • Demonstration of the fabrication of an indirect restoration with precision margins using microscopes
  • Where microscopy is used to study impressions and its benefit

Microscope positioning - demonstration 

Aims and objectives:

  • Understand how to set up the microscope and each individual element

  • The interpupillary distance for yourself
  • Understand how the clinician can position themselves for each sextant
