Dentistry is a branch of medicine, which encompasses science, art and mechanical engineering: the competent operator must be a master of all three disciplines. In this 3 part TubulesLive, Dr. Jason Smithson covers the art of the anterior direct composite, describing the protocol required to produce a class 4 restoration that is invisible to the human eye. This is followed by a more technical analysis of the process required to prepare and place a posterior composite resin restoration, which requires no or little occlusal adjustment. Finally, a novel technique is outlined which allows rapid restoration of deep class 1 cavities without post-operative sensitivity.

The dentist as an artist and a technician. Tips on anterior and posterior composite. Part 1 - Dr. Jason Smithson

Aims and objectives:

Gain an overview of posterior composites, taking into consideration:

  • The dentist as a technician (posterior)
  • Pre-operative status of the case, RCT referral
  • Isolation
  • Preparation, minimal, air abrasion
  • Material, dentine bonding agent, resin-modified glass ionomer, dentin shade, final
  • Adjustment free restorations, limited adjustment restorations
  • Aesthetics vs functional anatomy, form follows function
  • Occlusal compass
  • Invisible restorations
  • Simplified placement, placement with no. 6 probe, condense with microbrush, define the fissures
  • Successive build-up technique, enamel layering, MB, DB, MP, DP, light curing, timing
  • Concave dentin
  • Photographic documentation, standardised illumination, exposure settings and prospective
  • Selective enamel demineralisation
  • Neutralisation
  • Enamel and dentin, macrostructure
  • Internal effects
  • The third dimension, occluso-apical dimension, cuspal inclinations
  • Value modification
  • Final outcome
