Influence of dental implants on the accuracy of measuring the postoperative labial alveolar bone thickness in the maxillary anterior region: An in vivo CBCT study

The distance from the labial alveolar bone surface at the bone crest level to the implant neck, which comprises the thickness of the labial alveolar bone and the jumping gap, was smaller according to the CBCT data than the actual values obtained from intraoperative measurements. However, the average diameter of the 20 implants measured using the CBCT scans exceeded the actual implant diameter of 3.3 mm. When assessing the thickness of the labial alveolar bone around implants in the maxillary anterior region using CBCT during follow-up, a moderate underestimation of the labial bone thickness may occur.
