Long term facial alveolar bone changes associated with endosseous implants in the anterior maxilla.

Abstract

Inter-observer variability was determined using the Dahlberg formula. The percentage of sites with no FABr at each level was compared between sex, implant type and location using Fisher's Exact test (p ≤ 0.05).vi Results: 55% of all implants have no FABr at the implant/abutment interface. FABr thickness is greater in the apical as compared to the cervical half of all implants (p=0.04).Edentulous spaces restored with tapered implants showed greater radiographic FABr in the apical region than with parallel implants (p=0.04).

Evaluation of Alveolar Bone on Dental Implant Treatment using Cone Beam Computed Tomography

“…These results are slightly better than those found previously, which evaluated 168 dental implants in the anterior region with 56% of dental implants at level 7 (on implant platforms), 44% at level 6, 42% at level 5, 36% at level 4, 27% at level 3, 16% at level 2, and 14% at level 1 (at apical implant) with absolutely no buccal bone [13]. After an average of 8.9 years none of the dental implants they evaluated were covered with bone on the entire surface.…”
