“…It was applied twice a week for 20 minutes each session that commenced two weeks after stage I implant surgery and continued for 10 weeks. The intensity of ultrasound therapy used was 30 mW/cm2 with a frequency of 1.5 MHz and temporal average power of 20 mW, as per Kerr et al 15) . The same ultrasound therapy protocol was repeated 2 weeks after crown installation and continued for another 10 weeks.…”

“…The coronal and sagittal reference lines were set at the intersection point at the implant center that was to be examined. The peri-impant bone dimension measurements were done per Uzbek et al 15) . For linear measurements of bone height and width around dental implants, bony landmarks (points) were located and identifi ed and Linear Distance-Line connecting between two points were measured.…”

The aim of this study is to evaluate the eff ect of Low Intensity Pulsed Ultrasound (LIPUS) on marginal bone loss and osseointegration of dental implant using Cone Beam CT (CBCT) image analysis, torque wrench and Resonance Frequency Analysis (RFA) techniques. The study sample comprised of 22 patients; who were divided randomly into two equal groups (n=11). Each patient received one dental implant placed in the maxillary premolar region. Following fi rst stage implant surgery, in Group I, LIPUS was delivered to the implant operation site for 10 weeks before loading and for another 10 weeks post loading, while in control Group II, the implant wound was allowed to heal in the conventional way. The patients in both groups were followed up at 3 months and 6 months using clinical and radiological assessments that comprised of CBCT image analysis, Torque wrench and RFA values. The peri-implant bone height and width were measured and compared at three diff erent views (coronal, sagittal and axial) using CBCT at day 0, 3 months and 6 months. Statistical analysis using repeated measure ANOVA with signifi cance level of p<0.05 was employed for the evaluation and comparison within the same group and among the two diff erent groups based on specifi c time points. There was an increase in marginal bone level in Group I at six months post-operative and marginal bone lone loss in Group II within the same time interval. The marginal bone gain in Group I was statistically signifi cant at the buccal bone plate site. In both groups, there was an increase in torque wrench and RFA values but the increase was more signifi cant in Group I (LIPUS treated) compared to control group at six months post-operative. LIPUS promote bone healing around dental implant and can be utilized as a treatment modality to save implant with questionable stability and to enhance bone regeneration and quality osseointegration

“…Many studies have demonstrated that the height and especially the width of the alveolar ridge 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). A clinical study reported a reduction of 50% in the width of the alveolar ridge at 12 months and an average bone loss of between 5 and 7 mm (Schropp et al, 2003), leading to insufficient bone volume at the implant site.…”

“…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.

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.
