A free gingival impression for achieving optimal interdental papilla height: a case report

Area of Science:

• Dentistry
• Prosthodontics
• Periodontology

Background:

• Inadequate crown contours during dental restoration trials can lead to long-term free gingival form disharmony.
• Achieving precise gingival contours is crucial for successful and aesthetically pleasing dental prostheses.

Observation:

• This case report introduces a novel technique for capturing free gingival impressions, transitioning from a provisional restoration to a final zirconia crown.
• The technique involves creating two die casts from a single silicone impression: one for the zirconia crown and another for the provisional restoration and transfer coping.

Findings:

• A free gingival impression was successfully obtained using a provisionalized transfer coping, resulting in a detailed soft gingival model.
• The proximal contact position was effectively managed by predicting the convex curve of the interdental papillae.
• One year post-placement of the zirconia crown, no inflammation was observed around the interdental papillae, and symmetric papilla heights were maintained.

Implications:

• The two die-cast technique for free gingival impressions appears effective for achieving optimal interdental papilla height and form.
• This method can contribute to improved long-term gingival health and aesthetic outcomes in patients receiving zirconia crowns.
• This technique offers a valuable approach for clinicians aiming to enhance the precision of gingival contour management in restorative dentistry.
