We can differ from 4 interface models with differences in the supra connections. These 4 models of interface have their own attachments that are not compatible with each other. Therefore, each model has it´s own castable, Scan body and section in the libraries for CAD-CAM.
- Engaging interface: Designed for unitary restorations. It is made-up by a cylindrical part, with an engaging design at the base which consists in a lobe and two flat sides. It has a pinpoint groove for an optimal adjustment of the Scan body. Available in different gingival heights.
- Non-engaging interface: Designed for multiple restorations. The conicity of it´s body eases the insertion of the prosthesis even in some cases of divergence between axes. This cone supra connection has circular grooves that improves the retention of the cement. Available in different gingival heights.
- Non-engaging angled interface: Unlike the previous one, it has a lateral notch that, once we have angulated the chimney, it allows the insertion of the TPA screw and the placement of the driver to give the correct torque. It also has a groove to correctly orientate the Scan Body regarding the lateral notch.
- Multi-unit interface: The Multi-unit interface consists of a conical body with outer circular grooves, which eases and improves the insertion of the prosthesis and cementation. It is compatible with any straight or angled Multi-unit. This interface is used to design with our library for straight and angled jobs indistinctly.
The design of the scan body by IPD is the result of an extensive research of all current scanning technologies and materials used. Thanks to its precise manufacturing, it enables positioning of implants with the maximum precision, as well as the best definition due to the material used to make it: PEEK.
Scan bodies are designed to be used jointly with the Interfaces system, which extends their lifespan and reduces the need for stock. For this reason, IPD has launched 4 types of scan body: one for each of the before mentioned interfaces. The benefit for the client is that, with only these five scan bodies, any type of compatible connection can be worked via Interface.
The 
Hollow Screw System® is exclusively designed to be used with the straight IPD Interface system, providing provisional mechanical securing of the prosthesis to the interface without need of adhesives.
Its main feature is an opening on its longitudinal axis that enables the implant level screw to secure the interface to the implant. This allows the assembled interface-prosthesis system to be taken from the laboratory to the patient’s mouth, to make the corresponding occlusive tests. This new concept significantly simplifies the work in the laboratory, as there is no need for temporary cementation, with all the problems and disadvantages this entails. Either way, permanent cementation can be done in the laboratory, facilitating the work for the clinical specialist.
The Hollow Screw System® is manufactured in grade 5 titanium, therefore guaranteeing total biocompatibility and enabling the option of leaving the screw in the patient’s mouth permanently, complementing cementation and improving stability, reliability and durability of the structure. It is anodised blue to ease detection of the screw if it gets lost.

“The Hollow Screw System® facilitates the protocol both for the Technician and the Clinician, correcting imperfections in the temporary cementation.”
JOAN SAMPOL

“interfaces simplify the elaboration of restorations on implants in our daily activities. Thanks to these machined bases, the passive adjustment, both in small and extensive restorations is no longer a daily challenge. With a very simple protocol, we can save time in the process of generating a structure, regarding adjustment and passivity, thus having more time to invest in the development of the esthetical part.”
FERRAN LLANSANA
Consulting member of the Scientific Committee of IPD
“ interfaces are the ideal and natural solution for implant supported restorations, achieving optimum machined adjustments and ensuring the greatest biocompatibility with the surrounding soft tissues, after the use of ceramic materials placed on them.”
This anchoring system is complemented with a screwdriver especially designed for this screw. It has a practical and ergonomic design that facilitates holding and retaining the screw.
Based on a conical cross-shaped screwdriver with a reduction in diameter that acts as a guide to facilitate fitting. It has a standard flat milling on the upper part that allows it to be fitted to the most common RA Shank handles in the dental sector.
WORK SEQUENCE
- Exploded View: analog, prosthesis -castable -scan body, interface, Hollow Screw System® and permanent screw.
- Screwdriver for the Hollow Screw System®: displaying the work fitted with the tool for said system, showing simulated fitted tightening.
- crewdriver for the permanent screw: You can see how the tool for the permanent screw passes through the Hollow Screw System® and enables it to be tightened or loosened without any difficulty.
- Cementless temporary restoration: You can see how the prosthesis is provisionally secured to the interface without the need of adhesives thanks to the Hollow Screw System®
- CAD-CAM: Simplifies the scanning process in the laboratory, facilitating the manipulation of the attachments.
- Without provisional cementation: There is no need for provisional cementation in any of the adjustment phases of the prosthesis: Metal try-in, Bisque try-in and occlusion test.
- Oxidation free: As the Interface does not require to be heated in the furnace in order to remove temporary cement, there is no oxidation on its surface. It maintains dimensional integrity and surface color, resulting in a superior appearance and a precise adjustment with the implant.
- Less time and cost: Labour time and cost of laboratory work is reduced as there is no need to eliminate the provisional cementation.
- Security fixation system: Being made of grade 5 titanium, it can be left permanently in the patient’s mouth as a complementary safety element, additionally maintaining the post free from excess cement. Under no circumstances does it replace permanent cementation that secures the prosthesis to the interface.
- Different gingival heights: It offers a solution for practically all clinical cases and allows to keep the cement away from the tissues.
- Retention: The engraving on the supraconnections offers additional cement retention, making it possible to do without sandblasting.
- TiN coating: The golden titanium nitride coating offers a warmer and more natural colour for the restoration, as well as being chemically inert, uniform and reducing bacterial adherence.
- Higher ceramic thickness: Its parallel walls allow for thicker ceramic, reducing shadows even in difficult restorations.
- Standardised supraconnections: enables the stock of components required to be reduced. As a result IPD Interface system is the most cost-effective interface system on the market.
