Gelatine slightly reduced the gelation rate of CH hydrogel but improved its final mechanical properties in compression. LN had a minimal effect in normal medium but induced significantly more GAG production in degenerative medium (p less then 0.001, 4.7-fold superior to the control), reaching similar results to transforming growth factor (TGF)-β (used as a positive control). GAG production was further increased in CH-gelatine hydrogels, confirming an additive effect of LN and gelatine in a degenerative environment. The results supported the concept that CH-gelatine hydrogels supplemented with LN can help restore the function of the NP during the early stages of IVD degeneration.The purpose of this article is to assess the incidence of lingual foramina and associated vasculature in the anterior mandible to improve the understanding of their locations for dental implant placement. Intra-operative bleeding can be a significant complication. Pre-surgical assessment of the surgical site should be performed to identify anatomical landmarks. This can prevent a potential life-threatening haemorrhage that may compromise the airway. Nutrient canals can occur in the anterior mandible and have been reported to cause significant bleeding if violated. selleck products Using cone beam computerized tomography (CBCT) this study defines the anatomical locales in the mandible. CBCTs of 70 patients were obtained and examined for the presence of lingual foramina. The distance of lingual foramina to the inferior border of the mandible, bifurcations and propensity for the midline were assessed. Lingual foramina were found in all of the examined mandibles with variable configurations. CBCT may be important in planning for surgical procedures in the anterior mandible to prevent an unexpected hemorrhage. The present study is limited by its sample size, method of assessment and confinement to a geographical population. The results will need validation in further studies which may incorporate multiple assessment techniques and a larger sample size with to include greater geographical distribution. Future work may seek to describe emanations of the terminus of the sublingual artery.Systemic sclerosis is a rare multisystem autoimmune disorder that significantly impacts the orofacial region. Several oral features including microstomia and increased tooth loss contribute to the mouth-related disability. Prosthetic rehabilitation is very challenging in these patients. As the spectrum of dental implants indications has been recently extended to patients with various systemic disorders, the aim of this systematic review was to evaluate the outcome of dental implants in patients with systemic sclerosis. A literature search was conducted in Medline/PubMed database to identify eligible case-reports. 10 publications were included in qualitative synthesis. A total of 71 implants have been reported in 10 patients with systemic sclerosis with a mean of 7.1 +/- 3.8 implants per patient. Pre-implant surgeries have been described for 3 patients. Implant survival rates were higher than 98% but the mean follow-up time was only 28.3 +/- 18.6 months. Complications have been observed in 3 patients with 1 implant failure and peri-implant bone resorption in 2 patients. Although implant survival rates were high, an individualized assessment of risk-benefit balance is mandatory before indicating implant-based rehabilitation in patients suffering from systemic sclerosis and a scrupulous maintenance program has to be implemented. Further studies are strongly required to establish clinical guidelines.The aim of this report is to present a digital workflow technique to design a customized abutment for provisionalization of an immediate-placed implant based on the natural emergence profile of the tooth to be extracted. The workflow involves the combination of intraoral and CBCT scans, from which three-dimensional (3D) reconstructions of soft tissue and alveolar bone, as well as of the tooth to be extracted are obtained and exported as STL files. The files are imported to a computer-aided design (CAD) software, in which a virtual wax-up and custom abutment design are performed considering the natural emergence profile of the patient's tooth prior to extraction. Since the customized abutment is digitally designed, it can also be used as a scan body, to be directly scanned intraorally after soft tissue healing around an interim implant restoration. The custom abutment digitally designed can be then produced by milling zirconia with an optimally chosen color, in accordance with the aesthetic needs of the patient.
Bone augmentation and implant placement often lead to a coronal shift of the soft tissue. Therefore replacement of the mucogingival border during second-stage surgery is required. Different techniques have been described in the literature.
In this case report a new technique for second-stage surgery from a combination of a modified roll flap, an apically repositioned split thickness flap and thick free gingival grafts between the implants will be described for predictable gain of keratinized mucosa around and between dental implants.
Stable soft tissue conditions between the implants and buccal in the posterior maxilla could be gained showing almost no post-surgical resorption.
With this modified technique for second-stage surgery functional and esthetic results can be achieved.
With this modified technique for second-stage surgery functional and esthetic results can be achieved.Fungal sensitization is associated with poor asthma control. We aimed to determine the prevalence and factors associated with fungal asthma among Ugandan adults. Individuals aged ≥18 years with a new diagnosis of asthma in the last 12 months participating in the African Severe Asthma Program constituted the study population. Skin prick test results, clinical and demographic data were retrieved from the database, and serum Aspergillus fumigatus specific antibodies and total IgE were measured in stored blood. We enrolled 374 patients, median (IQR) age 34 (25-45) years, 286 (76.5%) females and 286 (76.5%) with severe asthma. Prevalence of Aspergillus fumigatus sensitization was 42.0% (95% CI 37.1-47.0%), allergic bronchopulmonary aspergillosis (ABPA) 3.2% (1.8-5.5%), severe asthma with fungal sensitization (SAFS) 16% (12.7-20.1%) and allergic bronchopulmonary mycosis (ABPM) 2.9% (1.7-5.2%). Older age (55-64 years) (crude odds ratio (cOR) = 2.6), sensitization to at least one allergen (cOR = 9.38) and hypertension (cOR = 1.
