Morphological Changes in Alveolar Bone Following Orthodontic Space Closure
… </em>Changes occurring in anterior alveolar bone following orthodontic tooth movement are controversial. Some research has shown that orthodontic tooth movement results in the adaptation of cortical bone; others have shown that it results in dehiscence and fenestrations.</p> …

Influence of Biomaterials in Alveolar Bone Regeneration and Preservation
… documented. However, they require a minimal bone quantity (in height and thickness). But alveolar bone defects are very frequent, for instance due to periodontitis, traumatism or acute dental infection. Moreover, a simple tooth extraction leads to significant bone resorption. Therefore, …

Assessment of Human Alveolar Bone Density by Using Volumetric CT Machine
<p>This study evaluated bone density in designated implants sites using cone-beam computed tomography (CBCT) and compared the measurements to those of quantitative computed tomography (QCT) and subjective bone density evaluation. Sixty-two designated implant sites in 9 human cadavers jaws were …

NG2/CSPG4 Regulates Alveolar Bone and PDL Microstructure in a Sex-Dependent Manner
Periodontal disease leads to alveolar bone loss through a complex, multifactorial process involving chronic inflammation. Understanding the molecular mechanisms that regulate bone formation and resorption in alveolar tissues is essential for identifying new therapeutic targets for periodontitis. …

CBCT Evaluation of Morphological Changes to Alveolar Bone Due to Orthodontic Tooth Movement
… the risk of potential damage to tooth roots and alveolar bone. A decision regarding the correct placement of the lower incisors will be largely determined by the amount of adaptation possible within the alveolar bone. Purpose: The purpose of this study was to use Cone Beam Computed Tomography …

Easily Applicable Fixation Method of Open Alveolar Bone Fractures in the Emergency Department
본 논문의 목적은 응급실에서 개방성 치조골 골절을 간편하게 고정하는 술기법을 연구하기 위함이었다. 저자는 2006년 1월부터 2006년 12월까지 본원 응급의료센터로 내원한 개방성 치조골 골절 환자를 대상으로 고정술의 효과를 비교하기 위하여 고정 후의 안정성, 교합상태, 출혈 정도, 시행 시간, 시행에 따른 어려운 점을 평가하였다. 총 8례가 본 연구의 대상이 되었으며, 모든 증례에서 고정술은 지혈에 효과적이었다. 각각의 환자는 고정술 후 확연한 출혈의 감소를 보였다. 4명의 환자는 철사를 이용하였고, 나머지 환자는 나일론봉합사를 …

Effect of Zoledronic Acid on Maxillary Alveolar Bone Coverage in Rice Rats With and Without Dental Trauma
… for the treatment of pathologies affecting bone remodeling. Currently they represent the most commonly prescribed therapy for osteoporosis, with over 5 million prescriptions filled in the United States every year. Over the last decade the use of high dose nitrogen-containing bisphosphonates …

Comparative Study on Alveolar Bone Level of Maxillary Molar Area and Anatomical Variation of Maxillary Sinus with CT Image
… to 2007, the presence of the amount of remaining bones and septum near the maxillary premolar and molar regions has been examined. Then, it has been found that the amount of remaining bones had significant differences by region and the frequency of septum and that of patients with the pathological …

The Incidence of Dental Caries, Periapical Root Resorption, and Alveolar Bone Loss Among the Navajo Indians of Monument Valley, Utah
… permanent tooth periapical root resorption, and alveolar bone loss was assessed. The relationship of tooth malpositioning to the specific parameter was subsequently determined.</p> <p>The sample was divided into arbitrary age groups.</p> <p>Periapical roentgenograms were taken of each subject and …

Digital Radiographic Analysis of Mineral Density of Adjacent Alveolar Bone in Relation to the Molar Translation Rate After Use of Retromolar Implant Anchorage
… related to the mineral density of adjacent alveolar bone. It was hypothesized that the rate of molar translation was inversely correlated with bone mineral density ahead of the moving tooth. Periapical radiographs were obtained every six months during 24 months of active treatment of eight …

Osteoimmunological Characterization of Borrelia burgdorferi-Induced Bone Loss: From Phenotype to Molecular Mechanisms
… and disseminates to various tissues, including bone. B. burgdorferi induces trabecular long bone loss in murine models, but its phenotype and molecular mechanisms remain unknown. Furthermore, it is not known if B. burgdorferi induces loss of alveolar bone (supporting teeth). We first conducted …

Three-Dimensional Evaluation of the Effect of Maxillary Incisor Retraction on the Palatal Bone and Root Resorption
… and labiolingual thickness of labial and palatal alveolar bone and incisor apical root resorption. <strong>Methods:</strong> Maxillary central incisor apical root resorption, labial and palatal alveolar bone height, and labiolingual thickness were assessed on pre-treatment and post-treatment …

An Investigation of the Effects of a Dietary Calcium and Vitamin D Supplement on the Resorption of the Alveolar Ridge of the Jaw in Immediate Denture Patients
… and vitamin D supplement on the resorption of alveolar bone following teeth extractions in human subjects. Studies have been cited which indicate a positive relationship between adequacy of calcium intake and maintenance of the bones of the jaw.</p> <p>In this investigation, patients who …

Prevalence of Bifid Mandibular Canals in a United States Dental School Population
… The mandibular canal, which houses the inferior alveolar neurovascular bundle, is a critical anatomic structure that needs to be accurately identified for mandibular dental procedures such as dental implant placement, extractions, and endodontic procedures. Damage to the mandibular neurovascular …

Maize and Bone: An Evaluation and Expansion of a Proposed Model for the Differential Diagnosis of Pellagra in Human Remains
… Collection were evaluated for caries, alveolar bone loss, periostitis, osteoporosis, cribra orbitalia, and porotic hyperostosis. Results indicate that the pellagra sample had lower rates of caries and alveolar bone loss, and higher rates of periostitis of the tibia and fibula in …

The Effect of Corticision on The Rate of Orthodontic Tooth Movement in Rats
… Orthodontic tooth movement (OTM) is a result of bone resorption and apposition; factors influencing the rate at which these processes take place may affect OTM. Various attempts have been made to shorten treatment time. The regional acceleratory phenomenon (RAP) has been used to modify the …

Influence of the Type of Grating Materials on the Rate of Bone Regeneration in Sinus Floor Elevation with Lateral Approach and Deferred Placement of Implants /// Влияние на вида на костновъзстановителните материали върху темповете на костна регенерация при повдигане на синусния под с латерален достъп и отсрочено поставяне на имплантати
… the fact that this region often presents loss of alveolar bone and increased maxillary sinus pneumatization, particularly when all of the molars are absent. The shortage and quality of the remaining bone often implies a challenge when rehabilitating with dental implants. Different kinds of grafts …
