简要总结
The alveolar ridge, a component of the periodontium, is crucial for maintaining both natural teeth and dental implants. Sufficient bone volume at the implant site is essential for achieving favorable biomechanics and long-term aesthetic results. After tooth loss, the alveolar bone experiences dimensional changes due to factors like periodontal disease, trauma, and pathology. These changes typically occur immediately following extraction and result in loss of ridge dimensionsin both horizontal and vertical directions, highlighting the importance of ridge augmentation for successful implant therapy.
Ridge augmentation around dental implants is essential for creating adequate bone volume and ensuring successful implant placement, especially in cases with significant bone loss or insufficient bone width and height.
A successful ridge augmentation depends majorly on tooth critical factors one is the type of graft used and the other is the stabilization of graft material.Although different types of membranes and titanium meshes are available to stabilize the graft additional screws or tags are needed to stabilize the membrane itself which stabilizing screw itself cause a wound and loss of bone around the implants.
To overcome this, tent pole abutments have been introduced to stabilize the graft in the vertical direction, but they lack horizontal stabilization.To overcome the above limitations, a modification of the abutment with wings will be introduced to support both horizontal and vertical components.
The winged abutments are tailor-made according to the type of defect and edentulous space.The winged abutments are made from castable abutments using cobalt chromium.
Although Various grafts and methods can be employed to achieve ridge augmentation, each with its specific techniques, advantages,and considerations ridge augmentationremains challenging. The study evaluates the efficacy of winged abutment and guided bone regeneration membranes in vertical and horizontal ridge augmentation around implants.
