PROPERTIES
The fibrous layer of RTR+ Membrane allows for the absorption of fluids, especially blood. From a mechanical point of view, this
It promotes stability and adhesion to the walls of the bone defect.
From a biological standpoint, this promotes bone regeneration. Fixation with sutures or pins is possible but not necessary. The dense layer has a smooth, glossy appearance. This gives the membrane a certain rigidity, allowing it to retain its shape even in the presence of moisture, and facilitates prolonged and easy manipulation in indications where it is combined with bone substitute biomaterials. Experimental data show that the membrane maintains its barrier function for over four weeks and then is completely resorbed.
in the body within four to six months. The synthetic origin of the polymer and its biodegradation into lactic and glycolic acid, naturally present in the body, give the RTR+ Membrane excellent biocompatibility, as demonstrated by experimental data obtained according to current standards.
INDICATIONS
RTR+ Membrane is a resorbable synthetic membrane indicated in oral, periodontal, and implant surgery for the treatment of
bone defects and bone preservation after tooth extraction in adults, with the exception of pregnant or breastfeeding women,
according to the following instructions:
> Preservation of alveolar bone volume following extraction
> Covering bone defects during the placement of immediate or delayed implants
> Alveolar ridge reconstruction
The RTR+ Membrane can be used alone or in combination with a graft or bone substitute.
CONTRAINDICATIONS
The RTR+ Membrane should not be used in the presence of active tissue infection at the implant site.
INSTRUCTIONS FOR USE
Opening the packaging: the RTR+ Membrane comes in double packaging. Open the first package and
Place the second one on a sterile field. Gently remove the membrane with the help of sterile surgical forceps, just before placement. In general, the RTR+ Membrane should be handled with care. The placement of the RTR+ Membrane implies adherence to the general principles of sterile handling and good surgical practices:
• a full-thickness mucoperiosteal flap must be created
and wide release incisions extending to the level of the teeth surrounding the site to be covered.
• The bone surface under the membrane must be perfectly clean and free of all soft tissue fragments.
• The RTR+ Membrane can be cut to size.
adapted to the size of the exposed defect. The membrane must cover the walls of the bone defect by at least two millimeters to ensure the barrier function.
• Position the fibrous (dull) layer facing the bone and the dense (shiny) layer facing the soft tissues. Do not separate the two layers of the membrane.
• Slide the membrane under the periosteum at the most fixed part of the flap, then apply the membrane to the bone defect. The fibrous layer absorbs any bloody exudates, promoting adhesion to the bone surface. At this stage, a sterile spatula can be used to optimize the shape or positioning of the membrane.
• The high mechanical strength of the RTR+ Membrane allows for its fixation, which may be indicated in order to prevent it from...
the displacement due to the effect of loading and mobilization.
• When the membrane is exposed, minimize contact with saliva to prevent bacterial contamination.
• The mucoperiosteal flap must be sutured to completely cover the membrane (e.g., with simple sutures and deep mattress sutures)
• If synthetic or biological materials are used to fill the bone defect, it should not be overfilled.
POST-OPERATIVE CARE
• Patients should undergo periodic follow-up and should be prescribed a mouthwash for fifteen days post-procedure. Level 1 analgesics are recommended for forty-eight hours in case of pain. Oral hygiene must be maintained. Brushing the site with a post-surgical toothbrush is recommended for forty-eight hours after the procedure. Healthcare personnel will inform the patient of the need to avoid excessive tobacco consumption and maintain proper oral hygiene for two weeks post-procedure.
• If the membrane is exposed, the dehiscence usually heals on its own within a few weeks.
• Membrane removal is generally not necessary, except in cases of acute infection. If membrane removal is necessary, adjacent tissues must be anesthetized with a local anesthetic and an incision must be made immediately adjacent to the membrane.
