B -TRJCALCIUM PHOSPHATE VERSUS DEMINERALIZED FREEZE-DRIED BONE AS AUGMENTATION MATERIALS IN IMMEDIATE DENTAL IMPLANTS

Abstract


The original Bn1nemark protocol advocated placing implants into existing edentulous ridges or extracting severely diseased teeth and placing the implants 6-12 months later, thereby permitting bone to form in the extraction sockets. However, starting in the 1980's, clinicians and researchers began to report the successful placement of titanium (root form) implants into bone sockets immediately after teeth were extracted. Frequently, pre-existing bony defects can be found in the extraction area. Depending on size, the bony defects may be treated with regener(l.tive techniques. Socket preservation is a term in implant dentistry, which implies the placement of various implantable materials within extraction sockets to maintain the socket anatomy. To date, there is inconclusive evidence that this procedure maintains the original socket dimensions. In contrast, evidence exist that placement of foreign materials into extraction sockets may interfere with normal bone formation. The current study was conducted to compare by linear and densitometric bone changes using direct digital radiography (Digora system)· between -tricalcium phosphates (B-TCP) and demineralized freeze-dried bone (DFDB) as grafting materials in immediate implantation. The present study comprised 12 ANKYLOS dental implants were inserted in 10 healthy patients immediately after extraction. Ages of the patients shared in this study ranged from 18-35 years old, 8 patients were males while 2 were female. All patients in our study have no any contraindications for surgical intervention.
