PRODUCTS 16 LOCATOR ® ATTACHMENT FOR COMFOUR ™ SYSTEM ACKNOWLEDGED RESTORATION CONCEPT FOR OVERDENTURES *LOCATOR ® is a registered trademark of Zest Anchors The COMFOUR ™ System by CAMLOG is distinguished by its application spectrum with a multitude of variants. Since April 2016, the angled bar abutments can also be restored with LOCATOR ® Attachments. The LOCATOR ® Attachment system (Fig. 1) with its patented technology, is a practi- cal and acknowledged treatment concept for overdenture restorations with implants for elderly edentulous patients, whose nancial means or hygienic abilities are limited through physical disability. How- ever, anchoring a prosthetic on two in- terforaminally placed implants is often an unsatisfactory solution as the prosthesis rotates around an axis during masticatory loading, which causes pain and sores and can thus initiate bone degradation. Good support to stabilize the prosthesis under masticatory loads, tilting movements and horizontally acting shearing forces, is par- ticularly important in this type of situation. The anatomical options in the atrophied jaw are severely limited for the placement of implants to achieve an adequately large load polygon. A good treatment option in this instance are the LOCATOR ® Attachments for straight and angled bar abutments. Taking the anatomical structures into considera- tion, a suf ciently large load polygon can be achieved with implants inserted at an angle without making elaborate bone augmentation necessary. As the overden- tures are supported in a resilient manner, the implants need to heal without being loaded in these cases. The bar abutments are inserted after approximately a three month healing period. Different proce- dures are possible for the fabrication of the prosthesis: 1. The LOCATOR ® Attachments are screw- retained and the LOCATOR ® Retention housings with corresponding replacement males worked directly into the existing prosthesis. 2. The LOCATOR ® Attachments are screw- retained and an impression taken with the aid of the impression caps. After fabricating the model, the prosthesis is fabricated on the model with the LOCATOR ® Retention housings and replacement males. 3. Impression taking is performed at the abutment level with the COMFOUR ™ Tita- nium caps. After fabricating the model, the LOCATOR ® Attachments are screw- retained and the prosthesis is fabricated on the model with the LOCATOR ® Retention housings and replacement males. The sur- gical intervention improves the condition of the prosthesis and the prosthetic sup- port. The resilience of the LOCATOR ® Sys- tem applies force speci cally to the hard and soft tissue and avoids tilting move- ment of the prosthesis during the chewing function – for the bene t and comfort of the patient. The COMFOUR ™ System also allows the conversion of an existing bar restoration to a LOCATOR ® -retained restoration without the need for changing the bar abutments. Complex, permanent implant-supported restorations inserted in younger patients, can lead to hygienic problems with advanc- ing age. Easy handling and cleanability of the denture is subject to prevailing individ- ual conditions, the manual and mental lim- its of elderly patients. Acceptable hygienic capabilities as well as aftercare of the orally screw-retained construction and also of the dentures, possibly through nursing personnel, through conversion of the bar restoration to a LOCATOR ® -retained den- ture is possible. 17° 4.0 mm 4.5 mm 30° 4.3 mm 6.0 mm Fig. 1: The LOCATOR ® Attachments can be supplied in two sizes depending on the implant diameter (3.3–4.3 mm or 5.0 mm). They are screwed onto the straight or angled COMFOUR ™ Abutments (17° or 30°).
