The Histological Effects Of Mandibular Distraction Osteogenesis On Rabbit Condyles, Eunice Jungmin Hong
The Histological Effects Of Mandibular Distraction Osteogenesis On Rabbit Condyles, Eunice Jungmin Hong
Loma Linda University Electronic Theses, Dissertations & Projects
The present study is a histological evaluation of condyles taken from rabbits that underwent either a midline or paramedian distraction osteogenesis procedure on the mandibles. Fifteen rabbits were originally operated on and eight of these fifteen successfully made it through both the distraction osteogenesis procedure and the 1 month holding period that followed. There was one control animal.
In the present study, the condyles from these nine rabbits (1 control, 2 midline distraction osteogenesis, 6 paramedian distraction osteogenesis) were prepared for histological evaluation (18 total). Step serial sections were cut along the coronal plane and the sections from the anterior …
Effects Of Various Hemostatic Agents On Bone, David Daryl Roland
Effects Of Various Hemostatic Agents On Bone, David Daryl Roland
Loma Linda University Electronic Theses, Dissertations & Projects
Previous studies have evaluated the effects of various hemostatic agents on radicular tissues following apical surgery. The purpose of this study was to examine the early osseous responses to seven hemostatic agents under identical conditions in rabbits. Sixteen adult male New Zealand white rabbits were used for this study. Following anesthesia, utilizing a midline submandibular incision, standardized bony defects were prepared on the lateral-superior regions of the mandible. Test materials were placed using standardized volumes and exposure times. Bone wax, Surgicel, Capset, alginate, Cut-Trol, Hemogin-L, and silver nitrate were compared to control sites irrigated with saline. Test materials or controls …

Quantification Of Bone Deposition In Onlay Bone Grafting, Gregory Alan Kammeyer
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study was to quantitatively evaluate; 1) mandibular posterior mono-cortical block onlay bone graft success rates 2) the amount of grafted bone retained after initial resorption in radiographic projections. Seven consecutive patients with 14 mandibular posterior implant sites requiring bone augmentation for implants of a standard 3.8mm x 10mm dimension were sought. Mono-cortical block bone grafts from the ipsilateral ascending ramus were placed then observed with two standardized CT scans, dividing them into two groups: Group A had the first CT at 4 weeks after graft placement and a second taken before Prosthodontic reconstruction, 36.7 weeks later. …
Assessment Of Alveolar Bone Density Using Implant Insertion Resistance Torque, Scott Sangmoo Lee
Assessment Of Alveolar Bone Density Using Implant Insertion Resistance Torque, Scott Sangmoo Lee
Loma Linda University Electronic Theses, Dissertations & Projects
Background: Implant stability during healing is a pre-requisite for successful osseointegration. In the case of early or immediate implant loading, it is necessary to achieve high level of stabilization during surgical placement. Fixture stabilization can be measured by resonance frequency analysis or implant insertion resistance torque measurement. The aim of this study is to correlate pre-operative radiographic bone density to implant insertion resistance torque in human cadaver jaw bone.
Materials & Methods: Sixty-four implant osteotomy sites in human cadaver jaw bones were previously examined radiographically using quantitative computed tomography (QCT) and quantitative cone-beam computed tomography (QCBCT). Forty-two implant insertion sites …
Distraction Osteogenesis In Edentulous Alveolar Bone With Rhbmp-2 Enhancement, Liviu F. Eftimie
Distraction Osteogenesis In Edentulous Alveolar Bone With Rhbmp-2 Enhancement, Liviu F. Eftimie
Loma Linda University Electronic Theses, Dissertations & Projects
Distraction osteogenesis, a unique system of affecting rapid bone healing in fractures, realigning malformed bones, and lengthening congenitally short and traumatically shortened bones has become an increasingly utilized technique for the maxillofacial region. The use of distraction osteogenesis has been described for increasing the height of edentulous mandibular alveolar ridges while concurrently forming new bone within the ridge to allow for adequate reconstruction. A standard protocol for performing distraction osteogenesis in the maxillofacial region has been well documented in the literature. Standard distraction osteogenesis requires an initial surgery to place the distraction osteogenesis device and mobilize the segment to be …
