Enhanced Lip-Contour During Facial Scan for 3D DSD and Implant Planning: A Blue Screen Approach.

Area of Science:

• Dentistry
• Medical Imaging
• Biotechnology

Background:

• 3D facial imaging for digital smile design (DSD) and dental implant planning often suffers from inaccuracies due to lip distortion.
• Precise planning for bone reduction in implant reconstructions is crucial.

Purpose of the Study:

• To introduce a clinical technique reducing facial scanning deformation for improved 3D DSD and implant planning.
• To enhance the accuracy of 3D visualization of the lip-tooth interface.

Main Methods:

• A custom-made silicone matrix was utilized, functioning as a blue screen during facial scanning.
• This technique was applied to a patient requiring a maxillary screw-retained implant-supported fixed complete denture.
• Volumetric changes in facial tissues were assessed with the silicone matrix in place.

Main Results:

• The silicone matrix effectively minimized deformation in the lip vermilion border region during face scanning.
• Imperceptible volumetric changes were observed in facial tissues with the matrix.
• The technique provided satisfactory precision in reproducing the lip contour and the transition to teeth.

Conclusions:

• The silicone matrix blue-screen technology overcomes common lip distortion issues in 3D facial scanning.
• Accurate lip contour reproduction improves communication and visualization for 3D DSD.
• Implementing this technology in reconstructive dentistry can increase predictability by reducing scanning errors.
