THE 9 PILLARS OF THE SUCCESS OF THE CONCEPT
We developed the HUG® subperiosteal implant in collaboration with Biotech Dental®.
It makes it possible to treat cases of severe bone atrophy without bone grafting and in a single procedure.
But HUG® is much more than a subperiosteal implant — it is an innovative concept, from the design and engineering of the implant to its implementation by the dental surgeon.
This concept is based on 9 pillars with a single objective: achieving the best possible tissue integration!
Come train with us and implement this concept in your practice for your patients!
A CUSTOM-DESIGNED IMPLANT TO PROMOTE BONE GROWTH
It all starts with an innovative design.
The optimized structure of HUG® ensures stability and bone compatibility.
Gyroid lattice structure:
- Controlled porosity of 50%, identical to the structure of cancellous bone.
- Promotes colonization of the biomaterial that covers the implant.
- Peripheral rim to facilitate bone growth over the implant.

SURFACE CONDITION AND ANODIZATION
Anodization has a beneficial effect on the osseointegration of titanium, and the pink color offers two advantages compared to other shades:
- Increases collagen synthesis and cellular visibility in vitro.
- Reduces aesthetic issues in case of gingival recession on a prosthetic arm.
The surface condition of the implant will be smooth or rough depending on anatomical areas and the tissues it contacts.

BIOMECHANICAL STUDIES
During its development, several designs were mechanically tested using finite element studies to determine the implant’s resistance to maximal occlusal forces.
But beyond development, each HUG® implant case is custom-designed for each individual patient.
This is why every delivered implant comes with a specific biomechanical study, systematically produced to ensure maximum safety for dentists and their patients.
The HUG subperiosteal implant is systematically accompanied by its finite element mathematical study, ensuring with safety factors :
- Its elastic deformation under a maximum unilateral load of 500 N.
- Its fatigue resistance for chewing cycles of 200 N over 15 years.
THE PTERYGOID ANCHORAGE
In the maxilla, in addition to the canine pillar and zygomatic anchorages, HUG® is the first subperiosteal implant to offer a pterygoid anchorage.
- Improves the stability of the implant, contributing to its proper osseointegration on a bone structure (the maxilla) with very low cortical density.
- Increases the bearing surface of the implant.
- Opposes the incisal occlusal forces that generate stress on the implant due to the significant cantilever between the bridge and the patient’s resorbed maxilla.
The pterygoid anchorage provides a solid and innovative fixation that is essential for success.

THE USE OF A CUTTING GUIDE
This cutting guide, when properly designed and used, is an integral part of the concept and allows:
- To adapt the bone to the implant.
- To harmonize the design of the implant and make it more uniform.
- To promote its tissue and bone integration.
- To reduce the risk of gingival recession around the implant pillars.
« A true precision key, the HUG® cutting guide ensures perfect bone adaptation, optimal biological integration, and long-lasting aesthetics by limiting gingival recessions. »

TISSUE MANAGEMENT
Bone grafting :
We recommend covering HUG® implants with a xenogeneic bone graft and sometimes a collagen membrane.
The goal is to create space between the periosteum and the implant and to achieve osseointegration above the implant structure.
Thickening of soft tissues: several solutions exist to increase soft tissue thickness:
- In the maxilla: shifting the incision palatally.
- In the mandible: using xenogeneic dermal matrices (Novomatrix®) or connective tissue grafts taken from the palate.
Optimize healing and stability through appropriate tissue management.

PMMA REPLICAS OF THE IMPLANT
The implants are delivered decontaminated in pouches ready to be sterilized.
You will therefore find PMMA replicas of the HUG® implant in the delivered package, along with a resin anatomical model of the case.
This allows you to practice safely before your surgery and test the adaptation of the implant to the bone structure.
Use replicas to train before the procedure and be more efficient on the day of surgery.
THE PROSTHESIS: AN INTEGRAL PART OF THE CONCEPT
Full cases : Definitive bridge and Ibarre framework machined in titanium:
- Implants are fixed with the bridge in place screwed onto the pillars.
- Thanks to its controlled workflow, for HUG® this is the definitive bridge.
- Even with severe bone atrophy, the patient leaves the procedure with their permanent teeth.
Partial cases : provisional Full PMMA bridge :
- This provisional bridge also allows precise positioning of the implants before fixing them to the bone and improves handling during surgery.
- This bridge can be left in place in underbite or removed and fitted 4 months after the procedure to load the HUG® implants before placing the definitive crowns.
A well-adapted prosthesis prolongs the lifespan and comfort of the implant.
« HUG® redefines immediate rehabilitation: thanks to its complete digital workflow, fully edentulous patients leave with their definitive bridge the same day, even in cases of severe atrophy. »
SECURE DIGITAL WORKFLOW AND DESIGN SOFTWARE AT YOUR FINGERTIPS
From the first selected case, all data is transmitted through Biotech Dental’s secure LaGalaxy® platform.
Once the design is completed, you can view it in extreme detail and validate it using the exclusive online Medprint® software.
Finally, for your surgery, a complete planning report is delivered with the implant, including the following information:
- Screw length and diameter.
- Their axis and face order to ensure perfect passivity on the bone structure.
From digital planning to placement, the optimized and secure workflow of the HUG implant ensures unmatched precision and speed.
