PRINCIPLES OF OVERDENTURE ON ONE-PIECE NARROW DENTAL IMPLANTS IN PATIENTS WITH DIFFERENT PATTERNS OF MANDIBULAR RIDGE RESORPTION (Abstract). Aim: To highlight the particularities of mandibular overdenture on one-piece narrow dental implants in patients with two frequent and high-difficulty clinical situations, namely flat alveolar ridge (also known as severe ridge resorption, when mainly vertic...

Secondary bone grafting in the alveolar cleft is performed to improve alveolar shape, guide permanent tooth eruption or move permanent teeth in the alveolar cleft area, and improve a concaved base in the nasal wing [1]. Such bone grafting is typically conducted 6-9 years before canine tooth eruption [2]. However, in some cases, patients obtain their permanent dentition without receiving bone gr...

BACKGROUND Porphyromonas gingivalis has been shown to invade osteoblasts and inhibit their differentiation and mineralization in vitro. However, it is unclear if P. gingivalis can invade osteoblasts in vivo and how this would affect alveolar osteoblast/osteoclast dynamics. This study aims to answer these questions using a periodontitis mouse model under repetitive P. gingivalis inoculations. ...

BACKGROUND It has been reported that the load for (or to) implant-supported restoration may lead to bone remodeling as bone resorption and/or formation. While many authors supported the process of bone resorption, others elaborated bone apposition and increasing bone density close and remote to implant body (or fixture). This may suggest the role of the implant to reserve alveolar ridge from ph...

Objectives were to measure labial alveolar resorption using Lamendin's method; to correlate the measured values of resorption with age at death; to determine whether age influences alveolar resorption, and if so, to quantify this impact. The study was performed during the 1992-1995 period in identified war casualties in Bosnia and Herzegovina. Data on the date, month and year of birth, and on t...

The role of the macrophage in the immunopathology of periodontitis has not been well defined. In this study, we show that intraoral inoculation of mice with Porphyromonas gingivalis resulted in infection, alveolar bone resorption, and a significant increase in F4/80(+) macrophages in gingival and submandibular lymph node tissues. Macrophage depletion using clodronate-liposomes resulted in a sig...

Polymethoxyflavonoids (PMFs) are a family of the natural compounds that mainly compise nobiletin, tangeretin, heptamethoxyflavone (HMF), and tetramethoxyflavone (TMF) in citrus fruits. PMFs have shown various biological functions, including anti-oxidative effects. We previously showed that nobiletin, tangeretin, and HMF all inhibited interleukin (IL)-1-mediated osteoclast differentiation via th...

The resorption of the residual alveolar ridges is a chronic and continuous process of bone remodeling. The aim of this study was to analyse the rate of residual ridge resorption at different sites in the both jaws in complete denture wearers, through a five-year period of denture wearing. Residual ridge changes were measured on successive lateral cephalograms at 5 measurement points of the maxi...

The purpose of this study was to determine the prevalence of abnormal alveolar bone in children and adolescents. Radiographs of 1026 patients were classified as showing negative, questionable, or positive evidence of abnormal alveolar bone resorption, based on criteria that included the distance between the cementoenamel junction to the alveolar bone and the integrity of the alveolar crest. App...
