A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Dentistry, Maxillo, Facial and Oral Surgery Johannesburg, 2017 / Introduction: The mandibular angle fracture remains one of the most common mandibular fractures with a reported incidence of ~20 – 40%. Its treatment is rife with controversy with a reported global complication rate of ~30%. Aim: The purpose of the study is to determine the optimum management of the compound, isolated mandibular angle fracture. Methods and materials: A prospective, randomised, study was carried out within the department where all cases of isolated, compound, mandibular angle fractures were allocated to 1 of the three treatment groups: Group1: Superior border wire; Group2: Single miniplate; Group3: Double miniplate. The patients were assessed for the presence of post-operative infection, malocclusion and fixation failure and the outcomes were correlated. The data was analysed statistically and reported upon using STATA. Results: 75 patients were included in the study with 25 patients per group. Complication rates were equal between the miniplate groups (16%), with the Superior border wire having the best outcomes. The average ―days to surgical fracture repair post-injury‖ (p = 0.08) and the category of ―severely displaced fractures‖ (>5mm) are the factors shown to increase the incidence of complications, p = 0.02. Overall a 13.3% complication rate was noted. Conclusion: The use of 2 miniplates seems to offer no benefit over a single miniplate. In stark contrast to previous global findings, fixation using a superior border wire with intermaxillary fixation (IMF) showed the best outcomes with a 92% success rate and its usage should be reaffirmed as a cost-effective alternative in a resource-constrained environment. / MT2017

Indiana University-Purdue University Indianapolis (IUPUI) / This investigation examined the relationships of preparation and resin material types in the reattachment of fractured anterior tooth fragments. A total of 44 extracted maxillary central incisors were tested. Statistical analysis revealed that no-handpiece preparation was as retentive as a 45° circumferential bevel (p <.01). In addition, the light-cured resin proved as retentive as did the chemically-cured resin (p<.01). Also examined was the effect of the initial fracture angle on retention of the fragment after reluting. Teeth fractured with an angle sloping cervically in a lingual-to-facial direction when viewed proximally were more retentive than other types of fractures when subjected to a lingually directed force from the labial (p L.OS).

Bone fracture, particularly that occurring in osteoporotic conditions, has become a major health issue. Fracture healing is a well-orchestrated regenerative process, the enhancement of which has been one of the major goals in fracture management. Low-magnitude high-frequency vibration (LMHFV) is osteogenic for intact bone and beneficial for limb blood circulation, which implies a potential of enhancement for fracture healing. Three parts of the experiments were conducted in this study to test the hypothesis that LMHFV would accelerate fracture healing by promoting chondrogenesis, endochondral ossification, and remodeling in both normal and osteoporotic bones. / Part I study. Three-month-old female SD rats underwent closed femoral fracture and were randomized into either vibration group (VG-I, 35Hz, 0.3g, 20min/day, 5days/week) or sham-treated control group (CG-I). Femora were harvested at 1, 2 and 4 weeks for micro-CT analysis, histomorphometry, and mechanical testing. Part II study. Osteoporotic model was established in nine-month-old SD rats after three months of inducement following ovariectomy. Similar grouping (VG-II and CG-II) and treatment regimes were performed after fracture, with the femora harvested at 2, 4 and 8 weeks for assessments like those in the Part I study. Part III study. After fracture, 3-month-old female SD rats were grouped (VG-III and CG-III) and treated as in the Part I study. At 1, 2 and 4 weeks, femora were collected for gene quantification (Col-1, Col-2, BMP-2, VEGF, and TGF-beta1) using real-time PCR. Type I and II collagens were located immunochemically in histological sections. / Results of the Part I and II studies demonstrated that LMHFV promoted callus formation (together with chondrogenesis), mineralization (endochondral ossification), and remodeling, which led to faster healing and better mechanical outcomes in both normal and osteoporotic fractures. In molecular level, the effect of LMHFV was reflected by the stimulation of chondrogenesis and osteogenesis related matrix collagen formation and growth factor expression. The molecular data echo Part I and II findings well. This study proved that LMHFV accelerated fracture healing by promoting chondrogenesis, endochondral ossification, and remodeling in both normal and osteoporotic bones, and indicated great potential of its future clinical application on fracture healing. / Shi, Hongfei. / Adviser: Kwok-Sui Leung. / Source: Dissertation Abstracts International, Volume: 70-06, Section: B, page: 3422. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2008. / Includes bibliographical references (leaves 180-201). / Electronic reproduction.
