IPG-DET technique is a surgical procedure that interfaces with the upper posterior jaw to support dental implants and a future dental prosthesis. [ 1 ] [ 2 ] The basis of this innovative technique is a biological process called osseointegration where materials, such as titanium, form an intimate bond to bone.
The GBR principle was first examined by Dahlin et al. in 1988 on rats. The selective ingrowth of bone-forming cells into a bone defect region could be improved if the adjacent tissue is kept away with a membrane; this was confirmed in a study by Kostopoulos and Karring in 1994. GBR can be used for bone regeneration on exposed implant coils . [4]
Dental implants require bones underneath them for support and proper integration into the mouth. As mentioned earlier bone grafts come in various forms such as autologous (from the same person), Allograft, Xenograft (mainly bovine bone), and Alloplastic materials. Bone grafts can be used prior to implant placement or simultaneously. [20]
Alveolar bone resorption is a common side effect of tooth removal (extraction) due to severe tooth decay, trauma, or infection that limits dental implant placement. Surgical bone augmentation is associated with limitations such as high cost, bone graft rejection or failure, pain, infection, and the addition of 6–12 months to the treatment ...
Over time, screw-root form designs experience bone resorption and "bone modelling and remodelling at the bone to implant interface". [9] Plateau-root form dental implants of 3 different sizes. Plateau-root form designed implants have a different healing process to screw-root form designs. The plateau-root form design has a woven bone formation.
The minimal bone height for a standard implant placement in the posterior region of the upper jaw should be about 10 mm to ensure acceptable implant survival. [3] When there is inadequate bone available, bone grafting procedures and sinus lift procedures may be carried out to increase the volume of bone.
