Wilson JP, et al. - Given that previous studies have defined minimum mesiodistal space (MS) and faciolingual alveolar width (FAW) requirements for dental implant sites, and inability to observe these limitations may adversely affect peri-implant health and esthetics, researchers conducted this investigation to determine frequencies at which anterior tooth positions present favorable MS and FAW for implant accommodation. Two hundred five cone-beam computed tomographic images were analyzed by a single examiner, recording MS and FAW available for implant placement at anterior tooth positions. According to results, mandibular incisor positions often presented unfavorable MS in the population evaluated to accommodate conventional implants with a narrow diameter. Additionally, when conventional narrow-diameter implants are used, considerable proportions of mandibular incisor and maxillary lateral incisor sites may be at risk of developing unfavorable peri-implant bone thickness.
