简要总结
Twenty patients with non restorable maxillary molar that indicate to immediate implant will be included in this study. The patients will be divided randomly (10 patients each group). Group I(study),immediate implant placement will be done using root guide technique.Group II(control),immediate implant placement will be done using surgical guide technique.The patients will be received, clinically and radiologically examined, and managed at the Oral and Maxillofacial surgery Department,Faculty of Dentistry, Tanta University.The patients will be evaluated clinically to evaluate healing and radio graphically using cone beam CT (CBCT) scan to identify bone density post operative and after 6 months.
详细描述
Purpose: This study aimed to evaluate the accuracy of the root guide technique in comparison to the surgical guide technique for immediate implant placement in the maxillary- molar region radiographically and clinically.
Materials & Methods:Twenty patients with non restorable maxillary molar will be included in this study. The patients will be divided randomly (10 patients each group). Group I,immediate implant placement will be done using root guide technique.Group II,immediate implant placement will be done using surgical guide technique.The patients will be received, clinically and radiologically examined, and managed at the Oral and Maxillofacial surgery Department,Faculty of Dentistry, Tanta University.The patients will be evaluated clinically to evaluate healing and radio graphically using cone beam CT (CBCT) scan to identify bone density post operative and after 6 months.
Preoperative evaluation: The patients will be evaluated clinically and radiographically using Cone beam CT(CBCT) scan , before implant placement for assessment of the anatomy of inter-radicular septum and tooth roots ,periapical pathology , bone density and approximation of vital structures , then we will make virtual planning to future implant position.
-
fabrication of surgical guide stent( tooth born ): will be done for Group II, Conventional impression will be taken with irreversible hydrocolloid to make a diagnostic cast.
-
The cast will be scanned with a laboratory scanner.
-
-The scanned data of the cast will exported as a standard tessellation language (STL) file, while the CBCT image will saved as Digital Imaging and Communications in Medicine (DICOM) data 26 .
-
-Design of the surgical guide proceeded with superimposition of the STL file to the CBCT data through a software [Blue Sky software].⃰
-
-Completion of virtual implant treatment planning with proper adjustment, the adequate position of the implant will planned with the creation of open sleeve.
-
-Selection and fabrication of surgical guide based on the computed tomography model and print it by Creality LD006 ⃰⃰
