Kret split tekniği ile eş zamanlı implant uygulanması; bir vaka raporu - Simultaneous implant placement with the crest split technique; a case report

Bone resorption following tooth loss is a natural process. In alveolar resorption cases, difficulties in implant placement may occur. Various techniques, such as the ridge splitting(RS) technique, are used to obtain ideal alveolar bone for implant placement.In this case report, 58 years old woman patient with horizontal alveolar bone deficiency in the maxillary anterior region was treated with the RS technique and simultaneous implant placement.Piezosurgery was used to divide the alveolar ridge, and the implant sites were prepared with osseodensification set.The splitting process was completed with bone chisels, and implants were placed simultaneously.Contour augmentation was planned for the maxillary anterior region, and the operation was concluded with the application of xenografts and collagen membranes.The RS technique has some advantages and disadvantages.Bone plates may fracture during bone plate separation, implant drilling and placement. The placement angles of implants may be unpredictable due to changes in the angles of the bone plates. In this technique, there is no need for a second surgical donor site, simultaneous implant placement is possible in most cases and treatment time is shortened.This technique also utilizes autogenous bone plates with intact nutrition.In this way, the uncertainty of the new bone formation process does not affect the osseointegration process. Compared to rotary systems, the use of piezosurgery eliminates the risk of damage to adjacent tissues, provides more controlled incisions, but may prolong the operation time.This RS technique is considered more predictable, reliable, and successful compared to other techniques such as autogenous onlay bone grafting and guided bone regeneration.
