Area of Science:

  • Dental Prosthetics
  • Biomaterials Science
  • Oral Rehabilitation

Background:

  • Aesthetic concerns with traditional removable partial dentures often stem from visible facial clasps.
  • Alternative designs are needed to improve patient satisfaction and compliance.

Purpose of the Study:

  • To describe a removable partial denture design with a lateral path of insertion.
  • To address aesthetic objections to conventional clasps in prosthetic dentistry.

Main Methods:

  • Utilized rounded rest seat preparations to facilitate lateral rotation of minor connector extensions.
  • Incorporated guiding planes on the contralateral side to ensure a distinct withdrawal path.
  • Illustrated the design using a Kennedy Class IV arch with an extended edentulous span.

Main Results:

  • The described design allows for lateral rotation into embrasure undercuts, providing mechanical retention.
  • Guiding planes ensure controlled dislodgement, independent of retentive elements.
  • Demonstrated feasibility in a complex clinical scenario (Kennedy Class IV).

Conclusions:

  • A lateral path of insertion for removable partial dentures offers an aesthetic alternative to traditional clasp designs.
  • This technique enhances patient acceptance by minimizing visible components.
  • The design provides predictable retention and stability through specific preparation and guidance features.
