1. Lack of parallelism
2. Positioning
3. Mechanical adaptation requirements

The following options for implant prosthetics are identical to natural abutments:

1. Fixed Bridges.  Often requires segmentation and attachments for parallelism.
2. Fixed Removable Bridges
3. Combination of Fixed and Removable.  Often fixed bridgework may be implemented in the anterior region, and a removable partial denture in the posterior. To avoid the negative esthetics and force distribution of clasp retention, precision attachments should be selected.
4. Removable Prosthesis

The most popular selection is a Removable Prosthesis, due to ease of implant inspection, servicing, hygiene, and maintenance. Three approaches are available:

a. Bars--provide outstanding stability

b. Stud Overdentures--must be parallel  

The Sphero Flex is combination abutment and ball attachment that compensates for up to 15º deviation from parallel and is the stud attachment of choice for all implant cases.  The LOCATOR can handle up to 40º of divergence between abutments.

c. Magnets--Do not require parallelism, have no specific path of insertion and significantly reduce or eliminate the transfer of lateral loads or torquing of the abutments.

The Locator Implant Abutment

This self-aligning ability of the attachment aids the patient in positioning their prosthesis in similar manner as a guide plane created by a milled bar. The implant retained overdenture can be properly seated without damage to the attachment components. This is especially important for a patient lacking anatomical structures necessary to orient their denture due to a severely resorbed mandibular ridge.

Clinical use has proven the ability of patient problems with inserting their implant retained overdenture to be solved in as little as one appointment.

Tested to provide retention for up to 60,000 retention cycles--28 times longer than the ERA®.

Precision Design and Milling Center

The PREAT Precision Design and Milling Center will assist you in designing your more complex and difficult implant fixed and removable prosthetics.

Overdenture bars, bars with attachments, hybrid "screw-down" dentures, and bridge frameworks are available in Titanium, ceramic chrome cobalt, and zirconium for all major implant systems.

Locator Bar Attachment System

The new LOCATOR Bar Attachment System contains the same self-aligning feature, superb retention, long lasting durability, and low attachment profile that you currently enjoy with our top selling LOCATOR Attachments. Now these benefits are available for your immediate use when the splinting of implants is required with a bar for added stability.

Sphero Flex Self Paralleling

The unique Sphero Flex is a self paralleling combination titanium implant abutment and ball attachment. It is the ball attachment of choice for all implants. It is designed for use on implant cases where there is up to 15º of deviation between implants, but can also be used on all other cases where both retention and stability is needed. The resiliency protects weaker abutments. The small size (the ball is 2.5mm) saves precious space. Preat Corporation can custom design a Sphero Flex abutment/attachment for you! All we need to know is the implant manufacturer, the diameter of the implant (specify internal, external hex, etc.), and the height or cuff length desired. The female component is a soft nylon (approximate life span: 12 months) with a metal housing that can be either seated in acrylic, or incorporated into a cast frame. The females give dental professionals the option of picking the females up chairside with self cure resin, or also can be processed in the denture by the laboratory.

Revax Hybrid Implant Bars

Prosthetic Concept of Resilient Construction

Prosthetic Concept of Rigid Construction

The Revax retained Hybrid prosthesis is a bar supported removable prosthesis. It may be tissue supported (resilient) or abutment supported (rigid).

When a limited number of implants are present in either the mandible or maxilla, the tissue supported overdenture is the preferred prosthetic option. When an adequate number of well integrated implants are present in an arch, a traditional fixed bridge is the prosthetic modality of choice. Often this is not an option in the maxilla, due to combined vertical and horizontal resorption, quality of bone, and position and/or flare of the implants. In this instance, a traditional fixed bridge would not meet patient requirements for hygiene maintenance, esthetics, phonetics, and comfort. The viable alternative is the rigid supported Revax bar removable prosthesis.

The concept is to separate support, lateral stabilization, and retention.

Each of these aspects can be altered according to the individual situation without influencing the other aspects of esthetics, phonetics, stabilization, oral hygiene, and patient comfort. Support is derived from three elevated areas: on the midline, and on the extensions of a bar construction which primarily splints the implants. The distal support zones may be planned to be in the axis of rotation of the resilient hybrid prosthesis. Lateral stability is achieved by incorporating a cast frame into the removable prosthesis that closely fits the bar in a passive state. Retention is derived from two or four CEKA REVAX attachments with adjustable, serviceable retention without influencing support or stability.

Pin Screw

The Pin Screw system is a set or locking screw for dentist removable crown, bridges, or removable prosthesis over implant suprastructures or telescopic castings. The Pin Screw is primarily utilized horizontally with telescopic dentist removable prosthesis.

Choose either a 1.4 or 1.6 mm diameter pin screw. The screw length is 3.0 mm. The minimum crown wall thickness is 1.2 mm. The channel is 1.2 mm for the 1.4 screw, and 1.4mm for the 1.6 mm pin screw. The locking screw bore depth is 0.7 mm for the 1.2 screw and .8 mm for the 1.6 pin screw.

New Double Mandrel BPD

By inverting the BPD,

• no metal is shown on the occlusal surface for better esthetics. 
• placing the male extracoronal of the crown does not require additional space, or abutment reduction. 
• On long span bridges for mandibular implant cases, the female tends to follow the taper of the male and allow for some flexing of the lower jaw.
