The role of cone beam computed tomoraphy (CBCT) for direct sinus lift in atrophic maxillary posterior region: Report of a case

In the posterior maxilla, unfavourable ridge resorption following dental extractions, sinus pneumatisation and poor quality of bone remain areas of concern. It becomes imperative to increase the height of the alveolar bone to facilitate implant placement in such regions. Pre surgical radiographic assessment using Cone Beam Computed Tomography (CBCT) allows the surgeon to plan implant insertion with ease. The article discusses the radiographic evaluation of gain in residual bone height after direct sinus lift technique using CBCT, thereby discussing its versatility and usage.
