“…In a recent review, Benic et al (13) stated that in ethically approved clinical research, three-dimensional imaging (computed tomography or cone beam computed tomography) can be used pre-and postoperatively to evaluate bone and soft tissues, as well as the implant position, with reference to the anatomic structures. Cone beam computed tomography imaging is increasingly being used for three-dimensional assessment of bone following ridge preservation (1,7,94), sinus floor elevation (53,93,106,143) and implant placement with simultaneous bone augmentation (23,31,77,83) or staged procedures following block grafts (97,98,129). Besides visualization of bony structures, cone beam computed tomography is also used to assess the contour and dimension of the periimplant mucosa (11,78).…”
