[A new clamp for the anchoring of partial removable prostheses]

Area of Science:

• Dental prosthetics
• Biomaterials science
• Mechanical engineering in dentistry

Context:

• Conventional dental clasps can present limitations in stability and retention.
• The need for improved prosthetic solutions in restorative dentistry is ongoing.
• Subtotal lower prostheses require robust and reliable retention mechanisms.

Purpose:

• To present a novel dental clasp design integrating two Ney type I clasps.
• To evaluate the clinical efficacy of this combined clasp system.
• To explore its application on cylindrical crowns or natural teeth.

Summary:

• A dental clasp design is proposed, utilizing two Ney type I clasps with overlapping vestibular arms acting on a single tooth.
• This design is applicable to both cylindrical crowns, such as inner telescopes, and natural tooth crowns.
• Clinical application has demonstrated significant success, particularly in the context of subtotal lower prostheses.

Impact:

• This novel clasp design offers a potentially more stable and retentive solution for dental prostheses.
• It may improve patient outcomes and satisfaction with subtotal lower dentures.
• The findings could influence future designs of dental clasps and prosthetic components.
