A hands-on guide to vonlays

ONLINE WORKSHOP

What to expect

This comprehensive hands-on at home workshop with Linda Greenwall and João Paulo Martins Esturrado is designed for dentists who wish to develop their knowledge and clinical skills in the use of minimally invasive posterior Volay restorations using GC lisi.

The innovative and engaging new course will explore the principles behind the vonlay concept, its indications and how it can provide a conservative alternative to more extensive indirect restorative approaches. Particular emphasis will be placed on understanding the characteristics of LiSi and how its composition, physical properties, optical qualities and bonding requirements differ from other commonly used restorative materials, including conventional lithium disilicate, zirconia and composite-based CAD/CAM materials.

Delegates will be guided through the clinical and digital design process, including case selection, occlusal assessment, preparation principles, restoration design, thickness considerations, margin positioning and the importance of maintaining a minimally invasive approach.

The theory session will then progress to the cementation process, covering surface conditioning, restoration preparation, tooth preparation, adhesive protocols, cement selection, isolation, seating, removal of excess cement and finishing and polishing. Particular attention will be given to avoiding common errors that may compromise retention, marginal integrity, aesthetics or long-term clinical performance.

During the hands-on session, delegates will have the opportunity to cement a LiSi vonlay using a structured, step-by-step protocol. This practical component will allow participants to translate the theoretical principles directly into clinical technique.

The course will also examine the benefits, limitations and potential risks of LiSi vonlays, enabling dentists to make informed clinical decisions and recognise cases where alternative restorative materials or techniques may be more appropriate.

Each delegate will be sent a specially prepared hamper with everything that you need to use during the hands-on section of the course.

João Paulo Martins Esturrado

João Paulo Martins Esturrado began his dental technology journey at 16, working in a local dental laboratory during school holidays. Growing up in a family of dentists, he gained early insight into the connection between clinical dentistry and laboratory craftsmanship. In 2013, he moved to London to broaden his experience, working with leading dental technicians and developing a philosophy that combines traditional craftsmanship with modern digital workflows. In 2020, during the Covid-19 pandemic, he accepted the opportunity to establish and lead a new dental laboratory, focusing on advanced materials, efficient digital workflows, and high-quality aesthetic restorations. Today, João is founder of Digitally Handcrafted and a Dental Technology Instructor at the Eastman Dental Institute, University College London (UCL). He is actively involved in teaching and mentoring dental professionals, with a focus on digital dentistry, clinician–technician communication, and integrating traditional principles into modern restorative workflows.

With an unwavering focus on product research and development, and a growing digital portfolio in the UK and Ireland, GC continues to shape the future of dentistry and create materials that become part of everyday dentistry.

You use it. We make it.

Feedback from past hands-on at home with Linda Greenwall delegates

I really enjoyed this workshop and also found it very convenient being able to do it all from home!

Amazing to have such an expert in this field provide courses like this
