The PreatLoc™ overdenture attachment system has been developed with an emphasis on predictability, efficiency, and long-term outcomes for practices and laboratories looking to balance performance with practical workflow integration. The attachment system draws on more than 45 years of experience in overdenture component design and laboratory support.
Preat has a longstanding history of working with clinicians and dental laboratories to support component selection, workflow efficiency, and restorative consistency. PreatLoc reflects this background, with design features intended to address current clinical needs while remaining familiar to teams already working with established overdenture attachment systems.
PreatLoc is engineered to be compatible with leading overdenture attachment systems, allowing incorporation into existing clinical and laboratory workflows without additional training or equipment changes. Key compatibility features include: no new tooling requirements; no new color-coding systems; ability to replace worn inserts directly with PreatLoc™ components; and straightforward use for both existing and new overdenture patients.
“The PreatLoc system is a true innovation in overdenture attachment technology,” says Lars Bouma, DDS, MS, FACP, Implant & Prosthodontic Associates. “The commitment to consistency of the inserts has increased my patients’ confidence. What sets Preat apart, beyond their superior engineering, is their unmatched customer service and attention to detail in every product they make. It’s a company that listens to clinicians and technicians—and it shows in every aspect of PreatLoc.”
PreatLoc attachments feature a zirconium nitride (ZrN) coating intended to support tissue compatibility. The coating is designed to reduce biofilm and plaque adhesion, which may help minimize soft tissue irritation and support long-term peri-implant health. The system is manufactured with defined tolerance parameters to support consistent retention forces across inserts. Quality assurance measures include 100% visual inspection of each insert and ongoing verification of pull-off forces to ensure consistency and reliability.
Angulation and retention options include: standard pivot accommodates up to 20 degrees of implant divergence; extended pivot accommodates up to 40 degrees of implant divergence; and retention levels and color options correspond to those used in leading overdenture attachment systems, supporting ease of transition.
An anodized pink titanium denture cap is designed to improve esthetics, particularly in cases with thin denture acrylic, while maintaining prosthesis contours and structural integrity.
Together, these features position PreatLoc as an attachment option intended to integrate smoothly into existing overdenture protocols while addressing material, mechanical, and esthetic considerations relevant to both clinicians and dental laboratories.
