1. Introduction

3D printing offers a wide range of treatment possibilities to dental clinicians. The added flexibility provided by digital tools and materials allows dental professionals to create new protocols while simplifying existing workflows. A perfect example of this is Formlabs' latest resin, IBT Flex Resin. This material was developed to enable digital workflows where conventional tools and materials – in this case transparent PVS – are being used. Combined with the Form 3B+ Stereolithography (SLA) 3D printer, IBT Flex Resin allows professionals to create customized, end-use appliances that meet clinical needs, enabling the transfer of a virtual wax-up design directly into patients' mouths without the need to print the physical wax-up model.

2. Case Presentation and Diagnosis

A 42-year-old female patient with no systemic health issues came to the clinic for a routine dental check-up. During the clinical examination, a composite restoration on tooth 11 was noticed. The patient reported to have had the restoration for more than 10 years. It had become unsightly, showing discoloration and poor surface condition. It was explained to the patient that it was possible to provide a new and better adapted restoration to rehabilitate the overall smile aesthetics. The patient was concerned by this option as, during the last repair of this restoration, she had needed to return after 48 hours due to the restoration coming off. The patient was reassured by the explanation that we would follow a complete bonding protocol under a dental rubber dam, ensuring the quality of the restoration and bonding.
