Introduction: Frontal bone fractures show a low frequency of occurrence of about 5% to 15% of all maxillofacial fractures occurring due to high-velocity injuries such as in the case of road traffic accidents, sporting events, assaults. Successful surgical management revolves around the concept of minimizing cosmetic deformity, maintaining normal sinus function, avoidance of short and long-term complications. In this article, the authors report a case series of 24 cases of frontal bone fracture treated with various treatment modalities. Materials and Methods: A total of 24 cases of frontal bone fracture admitted to our facility were treated accordingly and the subsequent follow up data were collected and compiled to be included in this study. Results: In our study, 83.33% cases showed isolated anterior table fractures, 8.3% cases with combined anterior and posterior table fractures. 40% cases managed conservatively, 41.6% with titanium mini plates, 12.5% cases with titanium mesh and 4% with cranialisation with fat obliteration. Conclusion: Our treatment decisions were based upon the extent and severity of the injuries which aided in tailoring the treatment modality. Thereby, curbing the long-term complications which could be foreseen and hence, a better functional outcome was achieved.
Fractures or other major bone defects in the mandible are commonly treated by mounting a reconstruction plate at the fracture site. To avoid complications due to loosening of the implant or the fixation screws, electrical stimulation presents a possibility to accelerate bone healing. The aim of this study was to investigate different combinations of activated electrodes and plate designs regarding their feasibility for electrostimulation of the mandibular bone. The electric field distribution for multiple implant designs was computed using the finite element method. The results suggest that the electrode insulation renders a crucial parameter, which influences substantially the stimulation impact and its power consumption.
As compared to other ethnic groups relatively few measurements on tooth size have been made on Indian population. Hence, a study was carried out in Department of Orthodontics, Saveetha Dental College, Chennai, to discern the average clinical crown dimensions for cervicoincisal heights (CIH) and mesiodistal widths (MDW), permanent dentition for the local population, to find out the amount of variation in CIH and MDW between males and females, between right and left sides and tooth showing maximum and minimum variation. The study was carried out on study models of 100 patients who visited the OPD of the above college, and measurements were done using Digital Vernier calipers. The results showed that CIH and MDW are generally larger for male teeth compared to female and left side 2nd molars showed clinically significant variation in CIH. The study also showed that in both sexes and arches maximum variation in CIH was for central incisor and minimum for 2nd molar. In MDW, maximum variation is for 2nd molar and minimum for 2nd premolars in both arches.The study is helpful in establishling Bolton's standards for assessing tooth size discrepancy and also in application of mixed dentition model analysis and bracket positioning chart for preadjusted edgewise appliance for the local population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
