Lecture: Assessment of Marginal Bone Stability around Dental Implants using Digital Radiography (CBCT)
As we are in an era of digital dentistry, for the dental surgeon the most important digital tool is the cone beam computed tomography (CBCT). The use of CBCT in oral surgery demonstrated its advantages which include high-resolution images, easy handling, and accessibility as well as low radiation dosage. We have come to rely on it as a pre-surgical assessment tool for all of our implant cases. Prior to digital radiography bone sounding and more aggressive tools were used to assess the residual ridge shape and bone defects. With the simplicity of this technology, we can accurately measure the anatomy of the alveolar bone at the implant site. Having marginal bone stability and a thick buccal plate of bone surrounding the dental implant increases its survival rate and improves esthetics by decreasing the chances for soft tissue recession. In this presentation, we will demonstrate the accuracy of CBCT in detecting the marginal bone level around implants that have been followed up for a minimum of 5 years.
1 - Understanding the added benefit of using digital radiography as a measuring tool for marginal bone levels around implants in three dimensions.
2 - To explore the factors that aid in maintaining marginal bone levels around short press-fit implants.
