Outcome Assessment On Skeletal Stability After Rigid External Distraction Osteogenesis In Cleft Lip And Palate Patients, Julio Enrique Tabarini
Outcome Assessment On Skeletal Stability After Rigid External Distraction Osteogenesis In Cleft Lip And Palate Patients, Julio Enrique Tabarini
All ETDs from UAB
Purpose: Distraction osteogenesis (DO) using an external distraction device in the correction of maxillary hypoplasia (MH) in cleft lip and palate patients has been shown to be an effective and stable technique. The purpose of this study is to determine the outcome of skeletal stability for this procedure using the Rigid External Distraction (RED) System in patients with cleft lip and palate (CLP). Materials and methods: Twenty CLP patients with moderate to severe maxillary hypoplasia were treated between June 2000 and June 2006. Their average age at the time of the surgery was 12.6 years. DO was started after a …
In Vitro Compressive Fracture Resistance Of The Human Maxillary First Premolar With Different Mod Cavity Design And Restorative Materials, Wen-Chou Wu
All ETDs from UAB
Cuspal failures of MOD (mesial-occlusal-distal) restored teeth have been constantly observed in clinic especially those restored with amalgam. As the pulpal depth and isthmus width of the preparation increases, the strength decreases. A number of studies have investigated the adhesive technique which is intended to increase the fracture resistance by bonding the tooth structure. The results of the studies are controversial because of the differences of research design among studies. The purpose of this study is to evaluate the fracture resistance of the human maxillary first premolar restored with condensable composite (Surefil, Dentsply) and CEREC 3D ProCAD leucite-reinforced ceramic inlays …
Vitamin D Receptor Deficiency And Postnatal Tooth Formation, Xueming Zhang
Vitamin D Receptor Deficiency And Postnatal Tooth Formation, Xueming Zhang
All ETDs from UAB
The reduction of caries is one of the major objectives of Healthy People 2010 (USDHHS, 2000). For individuals at risk for caries, early identification and interception before the occurrence of the disease are crucial to preventing the cariogenesis. However, host genetic variants that compromise the mineralization of dental enamel and dentin are unclear. The vdr mutation has been reported to be associated with bone loss. Therefore, it is likely that vitamin D resistance may affect dental enamel and dentin formation. The objective of this study was to investigate the effects of VDR deficiency on postnatal tooth formation in a vdr …
Micro-Computed Tomographic Analysis Of Bone Healing Subsequent To Graft Placement, Preeti M. Chopra
Micro-Computed Tomographic Analysis Of Bone Healing Subsequent To Graft Placement, Preeti M. Chopra
All ETDs from UAB
A MicroCT analysis of bone healing subsequent to graft (tri calcium phosphate/TCP) placement in the maxillary sinus prior to dental endosteal implant placement was the objective of the current study. Ten trephined rod shaped human bone cores were obtained three months after the placement of particulate graft material and the samples were stored immediately in 10% neutral buffered formalin. Using a Microcomputed tomography, the samples were evaluated at resolutions of 6 and 20μm. The thresholds for bone and graft material were determined using visual image, intensity (grey level) and histogram analyses. The graft and bone threshold was 235 greylevel and …
