OralMED x JUSTINLINE is making its debut at the 2026 summer festival season with an activation developed by NERVO, which was responsible for the creative concept, production, stand design and activation mechanics. The new invisible aligners brand has chosen Rock in Rio to introduce a more engaging approach aimed at younger audiences, through an interactive experience that combines entertainment, competition and product discovery.
Moving away from traditional clinical approaches, OralMED x JUSTINLINE is embracing the idea that “he who laughs last, laughs best”. To bring this concept to life, NERVO designed and produced a futuristic two-storey structure, created to capture festival-goers’ attention while delivering an experience that reflects the brand’s disruptive positioning.
The ground floor serves as the activation’s main hub, combining a product discovery and lead generation area with the experience’s central attraction: “The Final Line” game. On the upper floor, visitors can access a VIP space featuring mirror installations and lighting effects designed to showcase some of the festival’s most striking smiles.
The activation’s main attraction, “The Final Line”, transforms the journey of dental alignment into a physical and participatory experience. Inspired by the competitive mechanics of games such as Tetris and Jenga, as well as the challenge-based content formats popular among younger generations, the experience pits two teams of two players against each other.
At the centre of the experience stands a curved structure representing a smile. During a one-minute challenge, teams have just ten seconds per turn to place pieces correctly, following instructions displayed on surrounding screens, while attempting to keep the structure balanced until the very end. The objective is simple but demanding: keep the smile “aligned” until the final second and prove that, indeed, “he who laughs last, laughs best.”
“The main creative challenge was to turn the concept of dental alignment into a tangible, entertaining experience that would make sense within the context of Rock in Rio. After all, nobody goes to a summer festival looking for their next dental appointment. ‘The Final Line’ works precisely because it plays with tension and balance, two key elements shared both by games and by the journey of anyone seeking the perfect smile,” says Miguel Pires, Creative Partner at NERVO.
To further enhance the brand’s visibility across the venue, the activation also includes a LED wall positioned at the front of the stand to amplify the competition experience, as well as a large-format billboard at the rear of the structure featuring brand ambassadors Ricardo Weezy, Sara Maia, Miguel Queirós and Maria Flor Gameiro, hosts of the “Desalinhados” podcast.
From a production perspective, creating the experience required balancing technical robustness with a strong aesthetic vision.
“From a production standpoint, the main challenge was building a two-storey structure within a festival environment that combined the required durability with the futuristic and minimalist aesthetic demanded by the brand. The mechanics of the main game required extensive material testing to ensure the perfect balance between strength, stability and weight. On-site, our main focus will be ensuring that the entire countdown-based experience remains perfectly synchronised across the host, screens and participant interactions, without compromising visitor flow or the overall quality of the experience,” explains Tiago Tarracha, Managing Partner at NERVO.
With this activation, NERVO transforms the world of invisible orthodontics into an engaging entertainment experience, bringing OralMED x JUSTINLINE closer to new audiences through a creative, technology-driven and highly participatory approach.
