Cortical Plate is an osteoconductive graft made from 100% donated human cortical bone.
The shell technique involves using a thin plate of cortical bone, secured to host bone with at least two osteosynthesis screws, to create a biologic container that maintains the necessary space for bone graft particulates. Studies have shown that horizontal and vertical augmentation of an atrophied ridge is possible with thin blocks in combination with particulate bone grafts. (Khoury 2017)1
- Vertical augmentation
- Horizontal augmentation
- Tooth gaps
- The graft is preserved using LifeNet Health’s proprietary Preservon® technology
- Sterilized using patented and proprietary Allowash XG® technology, which provides a Sterility Assurance Level (SAL) of 10-6 without compromising the graft’s inherent osteoconductive properties2
- A minimum of 6 months healing time, is recommended
- Dimensions 30x15x1 mm
- Functions as a stable, slowly resorbed material that can be used as a substitute for autologous bone recovered from the mandibular shelf, eliminating the need for a second surgical site
- Ready to use out of the package, no need for rehydration
- Osteoconductive – Natural bone matrix facilitates cell attachment and proliferation
Important notes regarding procedure
- Host Bone Preparation: Perforating the host bone to create a bleeding site has been shown to improve outcomes.
- The plate should be at least 1 mm from the edge of the implant based on the desired implant position.
- Secure the plate so that there will be no movement of the plate with at least two screws to the patient’s bone. Predrilling the bone will reduce the risk of fracturing the plate, the use of low-profile screws is preferable. Do not countersink the screw heads.
- Prevent irritation or perforation of the soft tissue from sharp edges or corners on the plate using a burr.
- The space between the plate and the defect should be filed with particulate grafting material. The appropriate allograft mixed with some host bone can improve healing and incorporation of the construct.
- Coverage with a barrier membrane is recommended.
- Proper soft tissue management is essential to a good outcome. The soft tissue coverage must be tension free.
- A minimum of six months is recommended, however the healing time is best determined by the surgeon, based on the patient’s health and medical history.
