“The Effect Of Collagen Cone Blended With Gentamicin On The Success Of Dental Implant Placement In An Infected Site” (A Randomized Controlled Clinical Study)

Abstract

After extraction of the tooth, multiple physiologic changes to the hard and soft tissue of the alveolar ridge take place leading to a reduction in both vertical and horizontal dimensions. The average of this reduction reaches 50% in the horizontal dimension and 11-22% in the vertical dimension. This reduction interferes with the correct positioning of dental implants, especially in the esthetic zone. The present study was carried out to evaluate the use of collagen cone blended with gentamicin in chronically infected sockets and its effect on the success of the dental implant. The study aimed to compare the immediate placement of the implant following tooth extraction versus delayed placement of the implant four months after the treatment of the extraction socket with collagen cone impregnated with gentamicin in case of chronic infection. This comparison was done clinically and radiographically. Twenty patients were selected who required the extraction of non-restorable tooth with chronic infection and requested implant restoration. Two treatment modalities were carried out; the first one (ten patients) was extraction and placement of the implant immediately while the second (ten patients) was extraction and alveolar ridge preservation using collagen cone blended with gentamicin then implant placement 4 months later. Radiographic evaluations were performed by CBCT to measure the
