Using a 3D printed shell to reduce excessive gum display
Management of Excess Gingival Display Using Tunnel Technique With 3D Designed PEEK Shell: A Case Series
NA · Cairo University · NCT06017791
This study is testing a new 3D printed shell to see if it can help people with excessive gum display smile better compared to traditional surgery.

What this trial studies
This study evaluates the effectiveness of a tunnel technique that utilizes a 3D printed PEEK shell to address excessive gingival display (EGD) caused by a lack of lip support due to maxillary overgrowth. The intervention aims to fill the skeletal subnasal depression, which contributes to upper lip retraction during smiling. By comparing this method to traditional lip repositioning surgery, the study seeks to determine the stability and outcomes of this novel approach. Participants will undergo a thorough evaluation to ensure they meet specific cephalometric criteria related to their condition.
Who should consider this trial
Good fit: Ideal candidates are patients aged 20-60 with excessive gingival display of 2.5mm or more and an exaggerated subnasal concavity.
Not a fit: Patients who are pregnant, lactating, smokers, diabetics, or have parafunctional habits may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could provide a more effective solution for patients suffering from excessive gingival display, improving their aesthetic appearance and confidence.
How similar studies have performed: While there have been limited studies on similar techniques, this specific approach using a 3D printed PEEK shell is novel and has not been extensively tested.
