Overdenture Studs

Stud precision attachments are primarily used on roots and implants for retaining removable partial dentures or overdentures. All stud attachments MUST be parallel to each other to provide ease of insertion and removal and reduce wear potential. Do not engage labial soft tissue undercuts with the denture base flange, as this will alter the path of insertion and cause excessive wear and servicing requirements. Stud attachments are low in profile to reduce leverage upon the retaining abutments, are easy for patient hygiene maintenance, allow physiologic independent movement of abutments, and are easy to independently service.

Clix Ball Attachment

All previous balls–on overdentures for roots and implants, on crowns for removable partial dentures, and on top of bars for implant or root supported bridges–engaged the height of contour of the sphere to provide retention. This small area, or band of retention, may lead to early attachment wear and possibly frequent adjustment or replacement of the female unit.

The Clix design allows the female to engage all around the ball for an increased area of retention. Besides far greater retention than other spherical systems, the Clix offers the patient security of an audible click.

LOCATOR Attachment System

The LOCATOR is arguably the World’s most popular implant attachment system. Why and what does this mean to the dentist or dental technician as well as your patient? This page features troubleshooting techniques, videos, a basic overview of the components, retention inserts and more. If you still have questions we would be happy to assist you!

Ceka Revax Axial and Inverted Axial

Benefits:

  • Male on the post coping or bar for more prosthesis stability.
  • The acrylic retention cap may be easily removed (use heat) from the prosthesis and replaced or repositioned if necessary.
  • Clinical/Intra-oral: the acrylic retention cap is easily connected to a cast frame in the mouth
  • Clinical/Intra-oral: the acrylic retention cap may be easily picked up in the mouth

Preci Ball

The Preci Ball 22 is a resilient (full rotation) 2.25mm spherical stud attachment. It is a simple, effective systems, with many options to protect the abutments and retain both partials and overdentures. The spherical male attachment is available in a prefabricated orax alloy for soldering, a burnout plastic pattern for direct casting, and also a threaded male for direct casting or soldering. The female is available in a prefabricated alloy and a threaded female. There is also an optional threaded replaceable female.

The Preci Ball allows for an easy path of insertion and removal, adjustable female, and easy patient hygienic maintenance. All adjustments are made in the removable prosthesis. These features allow the dental professional to alter the attachment to fit the patient’s needs, not vice versa.

O-Ring Attachment System

The O-Ring Attachment features simple techniques, low cost, versatility, and is the most resilient option to protect weaker abutments

O-Ring Cast To: 3.20mm tall 3.00mm Ø tooth surface 4.50mm Ø housing

O-Ring Abutment: the extremely resilient titanium O-Ring attachment requires 4.0mm vertical, 5.0mm Ø

All abutments include (1) metal housing, (3) black final o-rings, and (1) red processing o-ring

Sphero Flex Post, Sphero Flex Abutment and Sphero Block

Direct Placement or cast coping

The Sphero Flex Post system is an endodontic post rotating ball attachment that corrects misalignment in any plane up to 15 degrees. The advantages of this self paralleling system are the freedom of movement (resiliency) that protects weak abutments, the biocompatibility of titanium, easy conventional techniques, and the small size of the sphere (2.5 mm). Also, no potential debris can enter the female, eliminating potential insertion problems. The female may be seated in the prosthesis, or incorporated in to a cast frame. The posts are available in three lengths– 6.75 mm, 8.40 mm, and 9.75 mm. The 2 degree precision reamer assures accuracy. This system can also be used with a cast coping.

ZAAG

  • Male freely rotates & moves within the housing, or denture cap. Male is replaced in seconds
  • Metal denture cap is in denture base resin
  • Wide band for increased retention area and decreased wear
  • Strong–wide shank prevents bending and breakage
  • Titanium coating for hardness and smooth internal surface
  • New contour adapts better to root

Zest Anchors

After 25 years of use, Zest Anchors has undergone a series of improvements to create the all new Zest Anchor Advanced Generation (ZAAG). Preat has a complete inventory of Zest parts and accessories for servicing existing prosthesis. We recommend the Locator Attachment for all new cases.

Magnet Systems

Magnetic systems provide:

    • no path of insertion for patients with limited dexterity
    • limited servicing requirements for the operator
    • up to 24º of rotation per abutment for non-parallel abutments
    • prosthesis may engage undercuts for increased stability
