Resorbable Barrier Effect In Sinus Graft Using Anorganic Bone, Kyung-Soo Choi
Resorbable Barrier Effect In Sinus Graft Using Anorganic Bone, Kyung-Soo Choi
Loma Linda University Electronic Theses, Dissertations & Projects
The effect of a resorbable membrane on new bone formation in human maxillary sinus augmentation using anorganic bovine material is unclear at the present time. As a pilot study, six patients who required bilateral maxillary sinus augmentations for endoessous dental implant treatment were grafted with anorganic bovine bone material. All six patients had a resorbable collagen membrane placed over the graft material on only one side for the sinus augmentation. At the time of implant placement, a minimum of 8 months following sinus graft healing, a biopsy was made of each side to permit histomorphometric analysis.
Similar amounts of new …
Influence Of Common Orthodontic Appliances On Magnetic Resonance Imaging, Joseph Matthew Elison
Influence Of Common Orthodontic Appliances On Magnetic Resonance Imaging, Joseph Matthew Elison
Loma Linda University Electronic Theses, Dissertations & Projects
Magnetic resonance imaging (MRI) is an essential diagnostic tool in modern medicine. Conditions such as cerebral vascular accidents, epilepsy and other seizure disorders, autism, cancer, migraine and cluster headaches benefit from its use. It has been discovered that 4-10% of all children and adolescents will experience a seizure at some point (Hauser, 1994) and MRI is one of the most common imaging modalities for seizure and epilepsy diagnosis. Unfortunately, some orthodontic materials cause distortion on MR images. Radiologists would probably require the removal of any distortion-causing orthodontic appliance prior to MR imaging. It is questionable whether radiologists would be comfortable …
The Effect Of Calcium Hydroxide Pastes On Root Dentin Fracture Resistance, Kurt W. Sturz
The Effect Of Calcium Hydroxide Pastes On Root Dentin Fracture Resistance, Kurt W. Sturz
Loma Linda University Electronic Theses, Dissertations & Projects
Calcium hydroxide is a common intracanal medicament used in the treatment of immature teeth that have been subjected to trauma or decay prior to root canal therapy. The effect of calcium hydroxide on immature root dentin is important. One area of concern is the effect that calcium hydroxide has on the fracture resistance of an immature tooth. It is the aim of this study to compare the effect of four different commercially available calcium hydroxide pastes on the fracture resistance of bovine teeth. Seventy-five freshly extracted, intact bovine incisors were prepared according to a modified Haapasalo and Orstavik technique. Each …
Bone Morphogenic Protein Induced Repair Of The Premaxillary Cleft, Rick J. Rawson
Bone Morphogenic Protein Induced Repair Of The Premaxillary Cleft, Rick J. Rawson
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study is to evaluate the bony augmentation of premaxillary clefts in humans using recombinant bone morphogenic protein (rhBMP-2) in a collagen sponge carrier. 12 patients with unilateral cleft alveolar ridges were evaluated pre- and 4 months postoperatively. 10 patients were repaired with rhBMP-2 while two others were grafted with anterior iliac crest particulate marrow cancellous bone (PMCB). Computed tomographic studies were used to evaluate preoperative alveolar cleft volumes, postoperative bone bridge volumes, and pre/post operative volume ratios.
A pre/post operative volume ratio for patients repaired with rhBMP-2 ranged from 24.1% to 90.6% with a mean of …
Mineralized Bone Allograft In Maxillary Sinuses Histology And Histomorphometry, Sammy Stefan Noumbissi
Mineralized Bone Allograft In Maxillary Sinuses Histology And Histomorphometry, Sammy Stefan Noumbissi
Loma Linda University Electronic Theses, Dissertations & Projects
Background: Demineralized freeze-dried bone allografts (DFDBA) and deproteinized bovine bone xenografts (DMBBX) have been used for sinus augmentation for many years with varying results, but very little has been reported on the clinical efficacy or the histological analysis of mineralized solvent dehydrated bone allografts (MSDBA) as sinus graft materials. This study histologically and histomorphometrically evaluated an MSDBA material called PUROS to augment atrophic human maxillary sinuses.
Materials & Methods: Seven partially and completely edentulous patients requiring unilateral (n=4) or bilateral (n=3) sinus grafts prior to implant placement were selected for this study. Test grafts consisted of MSDBA, and control …
