A technique for using maxillary anterior soft-tissue undercuts in denture placement: a case report

Area of Science:

• Dental Prosthodontics
• Biomaterials Science

Background:

• Restoring large anterior maxilla edentulous spaces with deep soft tissue undercuts poses significant challenges.
• Traditional prosthetic approaches may struggle to achieve adequate retention and patient comfort in such cases.

Observation:

• A partial denture was fabricated using a semi-rigid exterior flange and a soft liner, a technique termed "triple lamination."
• This prosthesis was designed to engage and utilize the depth of a soft tissue undercut.

Findings:

• The triple lamination technique successfully engaged the deep soft tissue undercut, actively contributing to prosthesis retention.
• Immediate denture placement was achieved with minimal postoperative tissue trauma and high patient comfort.
• The combination of materials in triple lamination proved effective for managing challenging undercuts.

Implications:

• Triple lamination offers a promising prosthetic solution for cases requiring engagement of deep soft tissue undercuts.
• This technique enhances denture stability, comfort, and immediate usability in complex anterior maxilla reconstructions.
• Consideration of triple lamination is recommended for clinicians facing retention challenges due to significant soft tissue undercuts.
