Let’s discuss the clinical try-in phase. On the left, you see a raw try-in – the teeth and gingival areas are monochromatic as it’s a monolithic print or mill, typically printed for cost-effectiveness. Traditionally, you’re accustomed to evaluating wax try-ins. I often find it amusing when presenting this concept to dental students – it’s a no-brainer whether they prefer handling wax or simply maneuvering a mouse. Students readily embrace this technology without the baggage of previous analog experience.

To enhance the try-in aesthetics, you can add some pink wax or triad material to differentiate the teeth from the base. Roane Dental Lab can provide suggestions for enhancing the printed try-in appearance, potentially even incorporating some tooth shading to an extent. But ultimately, it remains a monolithic try-in unit, regardless of whether you started with a wax rim bite, impressions over an existing denture, or the direct tooth setup workflow.

We’ll evaluate the try-in through three main phases. First, the patient tries it in, and you assess the fit. These try-in bases precisely replicate the anticipated final denture fit – a key advantage over traditional wax try-ins where the bases never accurately represented the final product due to blockout distortions. Here, you’re trying the actual final fit, so don’t expect improvements when proceeding to the definitive prosthesis. This try-in allows an accurate assessment to implement any needed fit modifications.

Next is the evaluation phase, scrutinizing aspects like midline, incisal lengths, lip support, etc. Make note of any adjustments needed, whether directly on the try-in or using the provided chart. Also, assess the bite relationship and determine if new impressions, a bite registration, or both are required. If the fit is acceptable but the bite is off, you may only need a bite registration. If neither is ideal, then new impressions and a bite are necessary.

This typical try-in appointment will likely involve one of those two pathways – impressions plus bite, or just a bite alone if the fit is satisfactory. A couple of quick tips: you can grind the lower posteriors to create space for impression materials and marking areas. I personally like to indicate tooth positions by drawing on the try-in with a marker, or simply grinding areas where I want the teeth positioned differently, as shown in this example.

There are multiple ways to communicate adjustments to the lab using these try-ins. If dealing with a particularly discerning or challenging patient, have them take the try-in home to evaluate in a relaxed setting. It may prevent a costly remake down the line if they’re not fully satisfied chairside.

And if significant changes are required after the first try-in, don’t hesitate to schedule another try-in appointment before proceeding to the final denture, even if it means charging for the additional try-in. It’s preferable to get everything exactly right through multiple verified try-in stages for challenging cases, rather than rushing prematurely to final delivery.
