A new field in dental implantology is developing with the goal of finding new ways to improve the osteoconductivity of bone substitutes and to study new molecules able to dictate cellular differentiation and improve bone regeneration. The real future in bone regeneration seems to be in connection with the rhBMP-2s, currently obtained by synthesis using recombinant DNA. Since the first rhBMP-2 studies in humans by Boyne, There are many studies for bone regeneration at oral and maxillofacial area. The rhBMP-2 is widely used at sinus augmentation, alveolar bone defect, and socket preservation.
BMPs are multi-functional growth factors which are members of the transforming growth factor-beta super family and their ability is that plays a pivotal roll in inducing bone. About 18 BMP family members have been identified and characterized. Among of them, BMP-2 and BMP-7 have significant importance in bone development. In this case reports, patients of maxillary sinus graft were received who visited LivingWell Dental Hospital. We focused on the results of the surgical intervention. We suggest that new strategy of treatment used to rhBMP-2 and -TCP scaffold for patients of sinus graft. The purpose of this paper is to give a brief overview of BMPs and to critically review the clinical data currently available on rhBMP-2 and synthetic bone scaffold.
To overcome shortcoming of autogeneous, allogenic, xenogenic and alloplastic bone grafts, various growth factors related to bone regeneration have been identified and developed. Among them, rhBMP-2 is regarded as the most potent osteoinductive growth factor and it can trigger the differentiation of mesenchymal stem cells to osteogenic cells for accelerated new bone formation And several commercial products of rhBMP-2 are available in Korea. It is applied to maxillary sinus augmentation, guided bone regeneration and preservation of extraction socket. In this review, the development, action mechanism and clinical applications of rhBMP-2 will be described.
Objectives: The objective of this work was to investigate the hospital nursing care of oral and maxillofacial health in jeju province. Methods: 438 Registered nurses(RN) who were working at each of secondary hospitals in Jeju province had responded to the questionnaire. The data were analyzed via frequency analyses and one-way ANOVA to assess the state of RN on hospital nursing care of oral and maxillofacial health. Results: The class of education on density in formal density that marked ‘0 hour’ and ‘1-3 hours’ were 73.5% and 19.9%, respectively. The class of refresher training on density that marked ‘0 hours’ and ‘1-3 hours’ were 92.9% and 6.6%, aggregately 99.5%. The nursing education on appearance after tumor of maxillofacial area that marked ‘formal education’ and ‘none’ were 45.2% and 52.1%, respectively. The score of question ‘function, effect and side effect of hexamedin gaggle’ was 2.68 0.95 by Likert 5-point scale. Likewise, the scores were 2.82 0.88 on question ‘management of removal denture’, 2.83 0.95 on question ‘preventive dental treatment before anticancer therapy’, 2.88 0.86 on question ‘function of saliva’, 2.96 0.99 on question ‘oral management of tube feeding patient’, 3.13 1.00 on question ‘bacterial endocarditis from oral microflora’, 3.36 0.89 on question ‘dysphagia’ and 3.62 1.03 on question ‘aspiration pneumonia’. RN replied that ‘lack of knowledge’ and ‘delay of cooperation’ formed 53.7% and 33.3% respectively, on question ‘problem in dental consultation other diseased patient’. Conclusions: From this study, it is necessary for RN and student of nursing science to be educated on the oral and maxillofacial nursing. Authors suggest further co-study and nation-wide research.
Obstructive sleep apnea (OSA), most common respiratory disorder of sleep, is characterized by intermittent partial or complete occlusions of the upper airway due to loss of upper airway dilating muscle activity during sleep superimposed on a narrow upper airway. Termination of these events usually requires arousal from sleep and results in sleep fragmentation and hypoxemia, which leads to poor quality of sleep, excessive daytime sleepiness, reduced quality of life and numerous other serious health consequences Untreated OSAS can cause various problems such as hypertension, diabetes, stroke, cardiac disease, daytime sleepiness. Various treatments are available, including non-surgical treatment such as medication or modification of life style, surgical treatment, continuous positive airway pressure (CPAP) and oral appliance (OA). Oral appliance is known to be effective in mild to moderate OSA, also genioglossus muscle advancement (GA) or maxillomandibluar advancement (MMA) is a good option for OSA patients with muscular or skeletal problems. Although the prevalence of OSA is increasing, the proportion of the patient treated by dentist is still very law. Dentists need to understand the mechanism of OSA and develop abilities to treat OSA patients with dental problems. The purpose of this paper is to give a brief overview about OSA and the dentist’s role in OSA patients
