实验性的:BioHPP Clasps Opposing Natural Tooth Abutments
Participants receive mandibular bilateral distal extension removable partial dentures with BioHPP clasps engaging natural tooth abutments.
The surface topography of the clasp fitting surfaces will be evaluated using scanning electron microscopy (SEM) at denture insertion, 6 months, and 12 months to assess surface wear.

实验性的:BioHPP Clasps Opposing Zirconia Abutmen
Participants receive mandibular bilateral distal extension removable partial dentures with BioHPP clasps engaging zirconia full-coverage abutments.
The surface topography of the clasp fitting surfaces will be evaluated using scanning electron microscopy (SEM) at denture insertion, 6 months, and 12 months to assess surface wear.
