Achieving optimal esthetics while maintaining retention, stability and healthy tooth structure has always been a problem with cast partial dentures. The use of clasps resulted in visible metal display drawing attention to the restoration. Abutment crowns and precision attachments eliminated visible metal but usually required extensive preparation of healthy tooth structure.

Now, with the Saddle-Lock Partial Denture Systems, clasp retained partial dentures can be created without visible metal — and, without the aid of cast crowns or expensive precision attachments.

Proven Retention

• clasp design utilizes only proximal walls (i.e. natural mesial and distal undercut planes) of abutment teeth
• concavities in these surfaces provide undercuts that improve retention
• clasp emergence back at casting finish line (provides necessary strength for proper resiliency)
• clasp terminals positioned at each end of denture saddle, locking segment to the ridge
  

"Retentoscope" Ensures Accurate Clasp Placement

• precision survey and design instrument employed in laboratory to precisely measure depth of undercut (ensures equal, yet gentle, clasp load on all abutments)
• clasps placed in exact location for ideal retention and biomechanics
• provides straight, vertical and effortless insertion of Saddle-Lock partials

Natural Management of Oral Stresses

• conventional buccal clasps transmit lateral stress during insertion (forces borne by abutment tooth alone)
• Saddle-Lock transmits stresses in anterior-posterior direction (utilizes adjoining teeth)
• guide plates in contact with guide plates of natural teeth not only resist lateral and horizontal forces but also assist with retention in same manner as precision-attachment intracoronal retainers

Cosmetically Natural Appearance

• need for unsightly buccal clasps eliminated
• no visible metal display

Flexible Design

• can be used with completely tooth-borne removable partial dentures and with both unilateral and bilateral distal extension prostheses
