Clinical Challenge
Anterior aesthetic cases often face dual constraints of space and material. Here, buccal prep space was extremely limited, and the design had to work within the dentist-specified 3M Lava zirconia block. The patient's neighboring teeth also had high incisal translucency, setting a high bar for chroma match and overall aesthetic harmony.

Framework Design
To balance "strength" and "anterior aesthetic translucency" within a limited space, Ping Ho adopts the following strategies:
The palatal side extends the zirconia to the incisal edge to ensure strength.
The labial side undergoes a 0.5 mm facial cutback and porcelain layering to balance both structural strength and aesthetic requirements.
Cutback 0.5mm
Technician's Insight
Under conditions where coping thickness is restricted and space is insufficient, we apply a pre-staining treatment to the coping surface before layering porcelain to enhance the overall chroma from the inside out, while using transparent stain to strengthen the incisal translucency.

Takeaway
Anterior aesthetic success depends on the clinician's preparation and the lab's deep understanding of material behavior.
Even with limited buccal space and a fixed material brand, pre-staining and precise cutback design let Ping Ho Dental Laboratory deliver restorations that balance strength and natural beauty.
