“…Lekovic et al (1998) reported an average buccal height reduction of 1.5 mm, Camargo et al (2000) reported 1 mm, and van der Weijden et al (2009) reported 1.67-2.03 mm. Most studies were consistent with the conclusion that the height reduction was more pronounced at the labial bone wall than at the palatal bone wall (Lekovic et al, 1998;Schropp et al, 2003;Araujo and Lindhe, 2005;Barone et al, 2008).…”

“…This might partially be the reason why studies using the method of flap elevation (Lekovic et al, 1998;Camargo et al, 2000) reported more resorption. Despite the inconsistent amount of bone resorption, most studies agreed the fact that the horizontal reduction was more pronounced at the labial bone wall than at the palatal bone wall (Lekovic et al, 1998;Schropp et al, 2003;Araujo and Lindhe, 2005;Barone et al, 2008).…”

Abstract:The purpose of this study was to apply cone-beam computed tomography (CBCT) to observe contour changes in human alveolar bone after tooth extraction of the maxillary central incisor and to provide original morphological evidence for aesthetic implant treatment in the maxillary anterior area. Forty patients were recruited into the study. Each patient had two CBCT scans (CBCT I and CBCT II), one taken before and one taken three months after tooth extraction of maxillary central incisor (test tooth T). A fixed anatomic reference point was used to orient the starting axial slice of the two scans. On three CBCT I axial slices, which represented the deep, middle, and shallow layers of the socket, labial and palatal alveolar bone widths of T were measured. The number of sagittal slices from the start point to the pulp centre of T was recorded. On three CBCT II axial slices, the pulp centres of extracted T were oriented according to the number of moved sagittal slices recorded in CBCT I. Labial and palatal alveolar bone widths at the oriented sites were measured. On the CBCT I axial slice which represented the middle layer of the socket, sagittal slices were reconstructed. Relevant distances of T on the sagittal slice were measured, as were the alveolar bone width and tooth length of the opposite central incisor. On the CBCT II axial slice, which represented the middle layer of the socket, relevant distances recorded in CBCT I were transferred on the sagittal slice. The height reduction of alveolar bone on labial and palatal sides was measured, as were the alveolar bone width and tooth length of the opposite central incisor at the oriented site. Intraobserver reliability assessed by intraclass correlation coefficients (ICCs) was high. Paired sample t-tests were performed. The alveolar bone width and tooth length of the opposite central incisor showed no statistical differences (P<0.05). The labial alveolar bone widths of T at the deep, middle, and shallow layers all showed statistical differences. However, no palatal alveolar bone widths showed any statistical differences. The width reduction of alveolar bone was 1.2, 1.6, and 2.7 mm at the deep, middle, and shallow layers, respectively. The height reduction of alveolar bone on labial and palatal sides of T both showed statistical differences, which was 1.9 and 1.1 mm, respectively.

“…11B). Comparative data from modern human populations (Lekovic et al 1998;Kiliaridis et al 2000;Christou and Kiliaridis 2007;Barone et al 2008) permit to provide minimum estimates of the "edentulous life span" of the D3900 individual. Assuming ~0.25-0.65mm of alveolar bone resorption per month of edentulous life [calculated from external and internal vertical wall loss over a period of 6-7 months (Lekovic et al 1998;Barone et al 2008)] results in a minimum of ~26-64 months of edentulous life.…”

Objectives: Due to the scarcity of the fossil record, in-vivo changes in the dentognathic system of early Homo are typically documented at the level of individual fossil specimens, and it remains difficult to draw population-level inferences about dietary habits, diet-related activities and lifestyle from individual patterns of dentognathic alterations. The Plio-Pleistocene hominin sample from Dmanisi (Georgia), dated to 1.77 million years ago, offers a unique opportunity to study in-vivo changes in the dentognathic system of individuals belonging to a single paleodeme of early Homo. Materials and Methods: We analyze dentognathic pathologies in the Dmanisi sample, and in comparative samples of modern Australian and Greenlander hunter-gatherer populations, applying clinical protocols of dentognathic diagnostics. Results: The Dmanisi hominins exhibit a similarly wide diversity and similar incidence of dentognathic pathologies as the modern human hunter-gatherer population samples investigated here. Dmanisi differs from the modern population samples in several respects: At young age tooth wear is already advanced, and pathologies are more prevalent. At old age, hypercementosis is substantial. Discussion: Results indicate that dentognathic pathologies and disease trajectories are largely similar in early Homo and modern humans, but that the disease load was higher in early Homo, probably as an effect of higher overall stress on the dentognathic system. Key words: aging, tooth wear, caries, periodontitisThe Plio-Pleistocene site of Dmanisi has yielded a large sample of hominin fossils associated with abundant and diverse faunal remains and Mode I stone artifacts (Gabunia et al. 2001;Ferring et al. 2011;Mgeladze et al. 2011). Occupation of the site began shortly after 1.85 Ma. The fossil hominin finds are dated to 1.77 Ma (Ferring et al. 2011). Dmanisi thus represents the earliest evidence of Homo outside of Africa. The well-preserved cranial, mandibular and postcranial remains of five individuals are unique in offering detailed insights into patterns of morphological variation within a paleodeme of early Homo, and into patterns of growth and aging Margvelashvili et al. 2013;Zollikofer et al. 2014). The craniomandibular morphology of the Dmanisi paleodeme has been described previously (Gabunia and Vekua 1995;Gabunia et al. 2000;Gabunia et al. 2001;Gabounia et al. 2002;Lordkipanidze et al. 2005;Lordkipanidze et al. 2006;Rightmire et al. 2006;Rightmire and Lordkipanidze 2010;Lordkipanidze et al. 2013;Margvelashvili et al. 2013). Cranial and mandibular morphological variation within the Dmanisi paleodeme is wide, but well within the range of variation seen in modern humans populations, and in populations of chimpanzee subspecies (Skinner et al. 2006;Lordkipanidze et al. 2013;Margvelashvili et al. 2013;Zollikofer et al. 2014). Variation in size, shape and dentognathic features among the Dmanisi mandibles has received special attention and has been studied to address questions of phylogeny, taxonomy, sexual dimorphism, die...
