In oral and maxillofacial surgery, tracheostomy is an occasional procedure in patients with inflammatory diseases, neo plastic diseases, and trauma. Subcutaneous emphysema is one of the complications of tracheostomy, and is consequence of air introduction or other gases into soft tissues. It is not a common complication, but it does occur occasionally. In 3 cases, Subcutaneous emphysema occurred after tracheostomy accompanied by oral and maxillofacial surgery. And it improved in 2, 3, and 13 days after the occurrence. The purpose of this study is to analyze the treatment and results of clinical cases of subcutaneous emphysema after tracheostomy in patients who underwent oral and maxillofacial surgery and use them as indicators of future treatment.
We report a case of a pediatric patient who developed systemic reactions due to nickel allergy after receiving stainless steel crown treatment for dental caries. The patient experienced eczema, itching, and rash on her thighs, gingiva, hands, and feet after the treatment. The symptoms were diagnosed as a nickel allergy reaction and were subsequently treated with first generation antihistamine. This case highlights the potential risk of developing nickel allergy reactions after receiving stainless steel crown treatment and emphasizes the importance of careful selection of materials and monitoring of patients during and after dental procedures.
Onlay block bone graft for vertical augmentation is quite difficult and has been performed by only oral and maxillofacial specialists. In specific situation such as severely resorbed posterior mandible, there is no other choice for implant surgery except block bone graft. Onlay block bone graft for dental implant in the severely resorbed posterior mandible could be achieved when the principles of block bone graft are carefully attained. In this article, principles for onlay block bone graft with surgical procedure were described.
When attempting to place a dental implant in a missing area, there is often not enough room for the restora tion because the surrounding teeth are tilted toward the missing area, there is an diastema, or the antagonistic teeth are extruding into the edentulous space. To create a functional and aesthetically pleasing prosthesis in such cases, it is essential to pre-establish a sufficient and normal-sized restorative space to achieve a more natural looking restoration. As part of the pre-implant treatment process, minor tooth movements can be performed to achieve this goal. The importance of orthodontic treatment in relation to implant therapy is often overlooked, but simple orthodontic tooth movements of adjacent teeth before the completion of implant prostheses can yield significant improvements. Implant therapy performed without correcting abnormal spaces can lead to vari ous biological and mechanical complications, highlighting the substantial value of such orthodontic treatment. Here, representative cases encountered in clinical practice involving common horizontal and vertical space is sues and their resolution through orthodontic intervention before completing implant prosthodontic procedure will be introduced.
Alveolar ridge preservation was introduced many years ago however, the concept is not widely accepted among the patients as well as the clinicians. Recently, the author has newly proposed the terminology of 'imme diate guided bone regeneration, iGBR' and the relocated clinical knowhow and iGBR has received lots of inter est since then. The clinicians should choose the indication for iGBR carefully, and the selection of biomaterials, compression knowhow, the application of polydeoxyribonucleotide, and the suture technique, Hidden X should be also considered. Especially, the open healing concept using collagen 3D matrix can produce wide zone of keratinized tissue by secondary healing and it may prevent the future peri-implantitis. In conclusion, iGBR is a patient and clinician friendly technique with lots of advantages in terms of hard and soft tissue.
