“…The observation interval of this study was three months, shorter than those of the abovementioned studies. Since the alveolar bone resorption continues throughout life (Jahangiri et al, 1998), the longer the interval, the greater will be the amount of bone resorption. In addition, it was well established that the elevation of a full-thickness flap might cause crestal alveolar bone loss of about 0.6 mm (Wood et al, 1972), making tooth extraction no longer the sole factor causing alveolar bone resorption (Fickl et al, 2008).…”

“…Generally, concurrent with new bone growth into the extraction socket, there is also resorption of the alveolar bone. Many studies have demonstrated that the height and especially the width of the alveolar bone decrease significantly after tooth extraction (Lam, 1960;Pietrokovski and Massler, 1967;Johnson, 1969;Jahangiri et al, 1998;Schropp et al, 2003;Araujo and Lindhe, 2005;Kerr et al, 2008;van der Weijden et al, 2009), leading to insufficient bone volume at the implant site.…”

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.

“…Generally, concurrent with new bone growth into the extraction socket, there is also well-documented resorption of the alveolar ridge, resulting in its decreased height and width (Lam, 1960;Pietrokovski and Massler, 1967;Johnson, 1969;Jahangiri et al, 1998;Schropp et al, 2003;Araujo and Lindhe, 2005;Kerr et al, 2008;van der Weijden et al, 2009).…”

Abstract:The purpose of this study was to demonstrate the feasibility of applying cone-beam computed tomography (CBCT) to observe dimensional changes in human alveolar bone continuously after tooth extraction. Sixty patients were selected from a CBCT database. Each patient had two CBCT scans (CBCT I and CBCT II), one taken before and one taken after implant surgery. A fixed anatomic reference point was used to orient the horizontal slice of the two scans. The alveolar ridge width was measured on the horizontal slice. In each series of CBCT I sagittal slices, the number of slices from the start point to the pulp center of the test tooth was recorded. The tooth length was measured on the sagittal slice. In each series of CBCT II slices, tooth length was measured on a sagittal slice selected based on the number of slices from the start point to the pulp center recorded in CBCT I. Intraobserver reliability, assessed by the intraclass correlation coefficient (ICC), was high. Paired sample t-tests of repeated measurements of both tooth length and alveolar bone width showed no statistically significant differences (P<0.05). This study has proved that projection differences among CBCT scans taken at different time points from one patient can be neglected without affecting the accuracy of millimeter scale measurements. CBCT is a reliable imaging tool for continuously observing dimensional changes in human alveolar bone.

“…1 Extreme resorption of the maxillary denture bearing area may lead to problems with prosthetic rehabilitation. These may be due to narrower, more constricted residual ridge as resorption progresses, decreased supporting tissues and a resultant large restorative space between the maxillary and mandibular residual ridge.…”

Rehabilitation of severely resorbed maxilla with a hollow maxillary complete denture

et al. 2014

View full text Add to dashboard Cite

Rehabilitation of severely resorbed maxilla poses a clinical challenge for fabrication of a successful maxillary complete denture. The increased interridge distance often results in a heavy maxillary complete denture that further reduces the retention and stability of the denture. This case report describes the rehabilitation of an edentulous patient with resorbed maxillary and mandibular ridges and an increased interridge distance by hollow maxillary complete denture so as to reduce the weight of the denture which enhances the retention and stability of the denture.
