This playlist is a workshop carried out by Dr Allesandro Conti in February 2017. Dr Conti provided insights into the use of microscopes and magnification in restorative dentistry and proceeded onto to show hands on elements of adhesive indirect and direct restorations.

Lecture 1. Introduction to microscope dentistry

Aims and objectives of Part 1

  • 1. Understand the optical characteristics and how microscopic vision works with the operator vision.
  • 2. Understand how the eyes accommodate to focus on the retina.
  • 3. Understand the reasons for eye strain and the symptoms.
  • 4. Understand how microscopes allow for improvement in these symptoms.
  • 5. Understand the benefits of microscopes over loupes.
  • 6. Understand loupes and the difference between Prismatic and Galilean loupes.
  • 7. Understand the differences between operative and diagnostic microscopes.
  • 8. Gain some good tips on how to adjust your microscope and its elements such as the eye piece etc to get the correct vision, setting inter-pupillary distance.
  • 9. Gain some tips on how to get the best focus on the microscope and the best patient and clinician positioning.

Part 2. Microscope Dentistry, Posture, Clinical Applications and Working position

Aims and objectives and learning outcomes

In this video you will learn about:

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

Part 3. Refining tooth preparation margins

Dr Conti gives a demonstration of how he refines a tooth preparation in order to move the tooth preparation margin. This first video does not have CPD as it is short.

Part 4. Tooth preparation for an anterior tooth

In this video, Dr Conti gives a demonstration of an anterior tooth preparation for an incisal fracture AND preparation for any onlay cavity.

Dr Conti discusses and shows by demonstration video:

  • 1. How to prepare the buccal chamfer
  • 2. How to finish the interproximal margins
  • 3. How to finish the margins to ensure a nice smooth restoration to tooth margin to gain an aesthetic result for an anterior restoration.

He then discusses the steps for an onlay preparation for a molar

  • 1. Occlusal reduction
  • 2. How to get interproximal reduction
  • 3. Tips on getting good buccal and palatal reduction
  • 4. Tips on getting good finishing lines using microscopes

Aims and Objectives of Part 4

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

Part 5. Rubber Dam Isolation Practical Video

Aims and objectives: of Part 5

  • Understand how to best use rubber dam
  • Understand how to get a good rubber dam position via a hands-on demo on a typodont model

Part 6. Cavities preparation for class IV cavities

Aims and objectives:

  • Cavities Preparation for Class IV cavities – gain tips on gaining preparation tips for maximum aesthetics.
  • Understand difference 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 of an old restoration.

Part 7. Workflow of an indirect composite - preparation to lab to cementation

Dr Conti and lab technician Davide Bertazzo talk about how they have made an indirect onlay in composite. Dr Conti demonstrates the preparation of the cavity and the core. Dr Bertazzo demonstrates how he prepares it in the lab and Dr Conti completes the process with his adhesion technique. He then demonstrates how you can also prepare and restore this via direct stratification. This video does not constitute verifiable CPD

Part 8. Composite stratification for a posterior cavity

Dr Conti demonstrates a step-by-step procedure for stratification build up of a posterior tooth with composite.

Aims and objectives of part 8

  • 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.

Part 9. Cementation phases of an onlay

Dr Conti demonstrates a step-by-step procedure for cementation of the onlays

Aims and objectives of Part 9

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

Part 10. Laboratory workflow using microscopes

Dr Davide Bettazzo provides an input into his lab workflow and how he prepares an indirect restoration using microscopes.

He provides an insight into the principles and aims of his daily work and how microscopes fit into this.

Aims and Objectives of part 10

  • Understanding the challenges within the dental laboratory workflow and how microscopy can help.
  • A demonstration of procedures where microscopy is used.
  • A full demonstration of fabrication of an indirect restoration with precision margins using microscopes.
  • A demonstration of where microscopy is used to study impressions and its benefits.

Part 11. Practical demonstration and positioning of the microscope

In this video, Dr Alessandro Conti explains how to use the Pico, with the varioscope and Mora interface and the positioning for your daily clinical needs.

Aims and objectives of Part 11

  • Understand how to set up the microscope and each individual elements.
  • Understand the intrapupillary distance for yourself.
  • Understand how the clinician can position themselves for each sextant.
