These Crazy Little Things – the MultiSafe Latch Attachment

Variant 2: Multisafe Telescope solution

The second fundamental variation is based on the provision of telescopic crowns. These are also primarily blocked. Here, the attachment to the abutment teeth is achieved by the equally blocked secondary crowns, which are usually faced with composite.

Whether to use an RSS or telescopic attachment is a matter of choice and is dependent to a large degree on the existing clinical situation. The majority of monoreductors that we make are RSS variants. The advantages are using tooth coloured anchor teeth with ceramic facings, and the retention provided by the abutments, when the denture is removed.

The height of the bite is also ensured. The telescope variant gives a slightly better fixing, with an easier handling on insertion. It does, however, require considerably more room due to the construction based on primary and secondary crowns.

This requires a greater loss of original tooth material during preparation and there is a risk that the final monoreductor is too bulky. When the denture is removed, the primary crowns are visible as gold caps, especially in the lower jaw. From a material/technical point, we prefer a metal ceramic veneer.

Advantages of key-slides

  • The integrated attachment is very good at absorbing all the forces arising (especially the transverse ones) and simplifies insertion by the patient
  • Only high-quality materials (Degulor, HSL, etc.) are used
  • Multisafe Automatically fits into the primary component
  • Is released automatically by a short pressure on the slide axis
  • Compact housing for difficult space conditions
  • Increased resorption of the alveolar ridge is avoided by regular relining
  • Longevity and a high degree of comfort for the patient if prepared according to their needs and checked on a six-monthly basis
  • Minimal perception as a foreign body by the patient and rapid acclimatisation phase


  • Demands a certain amount of dexterity and practice on insertion.
  • Special consideration with older people!
  • If one of the abutment teeth is lost, the denture cannot be rescued!
  • Also: cannot be extended
  • Needs to be particularly well-serviced in the upper jaw, when the saddle is affected by gravity


  • Removable cast denture with a sublingual arm or plate with cast clasps on the opposite side. A cost-effective solution with all the disadvantages of the clasp cast
  • Acrylic denture with curved metal clasps – no comment!
  • Implants, either as single implants or an implant bridge. Dependent on clinical suitability. Excellent and even more comfortable, but also the most expensive variant. Always associated with a clinical intervention
  • Combination of (own) abutment teeth, implants and slides are common possible alternatives
  • Cantilever bridge fixed alternative for the replacement of one tooth only up to premolar width. A cantilever bridge is a fixed bridge that attaches to adjacent teeth on one end only
