APPROVED BY EXPERTS

Expasyl & Cad-Cam
Dr. Fabienne Jordan-Combarieu
A preparation protocol is necessary prior to recording optical data. A system for gentle gum eversion and reliable haemostasis, such as Expasyl, is an essential part of this dental protocol. […] There is an additional specific advantage in using Expasyl with direct CAD/CAM (during treatment): the epithelial attachment is treated with care, which means that bonding can be carried out during the same clinical process whilst respecting the gum collarets during all the phases of creation, in a single operation.

Expasyl & Epithelial attachment
Dr. Jacques Charon
The epithelio-conjunctive attachment is the most fragile part of the periodontium. […] It is really important for the future of the prosthesis to not be iatrogenic. […] The Pierre Rolland laboratories were the first to propose to dental surgeons the Expasyl system which allows a gingival eviction without breaking the epithelio-conjunctive attachment.

THE PASTE THAT CAN BE USED IN ALL CLINICAL APPLICATIONS

Multiple Indications
Expasyl can be used in a wide range of cases:

Conventional and optical imprints
Sealing / Bonding
Conservative dentistry when restoring class II and V cavities
Implantology

02 MAIN CHARACTERISTICS

MAXIMUM EFFICIENCY

The paste opens the sulcus and dries it (bleeding, saliva, fluids) efficiently.
Adding an accessory, a solution or performing any other treatment is no longer necessary.
The cervical limits and emergence profile are perfectly accessible.

Expasyl enables the dental practitionner to obtain an horizontal sulcular opening significantly greater than with a cord⁽¹⁾ and generates a pressure 1.7 to 9.2 times higher than other retraction pastes on the market⁽²⁾.

ATRAUMATIC & PAINLESS PROCEDURE

Expasyl generates 37 times less pressure than cord (143 vs 5 396 kPa)(1).
The epithelial attachment is preserved (beyond 2 400 kPa the epithelial attachment integrity is no longer guaranteed)(2).
The risks of permanent gingival retraction and bone resorption are reduced.
There is no pain for the patient.

SIMPLE, FAST AND ECONOMICAL PROTOCOL

Time is better managed & procedure is simplified

Rinse / Dry the area
Setting in place: Expasyl is easily placed within 20 seconds into the sulcus.
Contact time: Expasyl is effective in only 1 to 2 minutes max.
Removal : Expasyl is easily removed with a gentle air-water spray.

Budget is controlled

With Expasyl, no anaesthesia, no other haemostasis are required.
Time-savings: up to five minutes per tooth (especially important in the case of multiple preparations).
Impression-taking in the same session, even if there is profuse bleeding during preparation.

04 TESTIMONIALS

Even though the majority of prosthetic steps are done using transfers and replicas, often avoiding aggression to the soft peri-implant tissue, clinicians may need a better view of the cervical edges of implants and must therefore keep in mind the fragility of the periimplant attachment (adhesion of the more vulnerable hemidesmosomes, collagen fibres running parallel to the main axis of the implant and therefore less anchored, peri-implant conjunctive tissue with fewer cells and blood vessels than the periodontal conjunctive tissue of a natural tooth, etc.).

05 CLINICAL CASE

Veneer restorations

Digital imprint

Porcelain caps

The teeth are prepared for veneer restorations. The limits are very slightly subgingival.

End of gingival retroversion with nothing but the use of Expasyl left on for 2 minutes.

After removing the product and drying the preparations, light silicone is applied to the incisal portion. It is pushed into the open sulcus with no trauma by the heavy silicone, using the triple mixture method.

Result of the imprint: the sulcular space is defined by the light silicone.

The temporary veneers are in place.

Final result one year after the procedure.
