    Introduction: The anterior crossbite is the oral encounter of the mandibular anterior teeth with the maxillary anterior teeth when it is in a central relationship. Objective: To determine the risk factors associated with CAM and what type of treatment is most recommended for the correction of CAM. Methodology: For this article we began the search for the information for which we accessed the following databases, PubMed, ESCOPUS, EBSCO. Results: The crossbite initially showed promise with the use of an acrylic adhesive palatine expander that, after fixation and coinciding with the replacement of the maxillary incisor and a reflex anterior sclera, was corrected with masking. The goal of correcting cross-over defects at an early age is to allow improvement of type III bone pattern and reduce the amount of dental compensation and bone misalignment typically associated with severe skeletal abnormalities in childhood; however, the inferiority is long treatment time depending on the types of treatments we are going to use. Conclusions: It is concluded that there must be an early diagnosis so that in this way an early treatment is carried out and thus future problems can be avoided, in such a way that it is necessary to comply with different factors to perform some type of treatment that the patient requires.Introducción: La mordida cruzada anterior es el encuentro bucalmente de los dientes anteriores mandibulares con los dientes anteriores maxilares cuando está en relación céntrica. Objetivo: Determinar los factores de riesgo asociados a la MCA y qué tipo de tratamiento es más recomendado para la corrección de la MCA. Metodología: Para el presente artículo se inició la búsqueda de la información para las cuales accedimos a las siguientes bases de datos, PubMed, ESCOPUS, EBSCO. Resultados: La mordida cruzada inicialmente se mostró prometedora con el uso de un expansor palatino adhesivo acrílico que, después de la fijación y coincidiendo con el reemplazo del incisivo maxilar y una esclerótica anterior refleja, se corrigió con enmascaramiento. El objetivo de corregir los defectos cruzados a una edad temprana es permitir la mejora del patrón óseo tipo III y reducir la cantidad de compensación dental y la desalineación ósea típicamente asociada con anomalías esqueléticas graves en la niñez; no obstante, la inferioridad es de largo tiempo del tratamiento según los tipos de tratamientos que vayamos a utilizar. Conclusiones: Se concluye que debe haber un diagnóstico temprano para que de esta manera se realice un tratamiento precoz y así se podrá evitar futuros problemas, de tal manera que se necesita cumplir con diferentes factores para realizarse algún tipo de tratamiento que requiere el paciente

    Introduction: The defects in the alveolar bone might appear as a result of congenital malformations, traumatic injuries, periodontal disease, surgical traumas, chronic periapical changes and tumors from benign or malignant origin. The aim of this study was to provide solid and healthy area with application of Bio-Oss in the defect. Materials and methods: Based on the clinical diagnosisestablished by previously taken history, clinical examination and radiographic images oral-surgery interventions was made. To realize the aim of this work, augmentative material was implicated in the bone defects made in the patients after removal of follicular cyst, chronic periapical lesion, and parodontopathia. During the first and seventh day of the interventions, the patients have been followed through from aspect of possible development of local and general complications after the oral-surgery intervention. After period of one, three and six mount control x-ray was made. Results: Obtained results confirmed that: volume of the socket and defect of the bone was kept, fast revascularization was achieved, bone formation and slow resorption of the augmentative material was achieved, and period of normal healing without infection was also achieved. Conclusions: The augmentative materials used for treatment of bone defects besides their basic chemical and physical characteristics referring to their solubility in the body fluids, the transformation, modulation and resorption must be completely safe or secure, i.e. not to bring any risk of infection, immunological risk, physiological intolerance or inhibition of the process of restitutio ad integrum. In our study Bio-Oss was confirmed as augmentative material who had this characteristics. Keywords: bone defect, resorption of the bone, augmentative material, Bio-Os

    The development of prosthetic dentistry provides improvement of different dental prostheses to increase the level of dental care efficiency. The manual is aimed to provide comprehension of the present day views on the arch prostheses production considering theoretical and practical value of classical techniques. The manual contains the programme material on prosthetic dentistry educational discipline and concerns the issues discussed in the section «Arch prosthetics». The current methods of arch prostheses fixation are widely covered in the manual as well as planning approaches and prosthesis design choice. Particular attention is paid to the basic technological stages of prostheses manufacturing. The text is illustrated with the color drawings improving the presented material comprehension, the list of questions is directed on self-control of acquired knowledge. The authors will be sincerely grateful to colleagues for constructive remarks and useful suggestions in improving the presented material. Authentic translation from Ukrainian Language

The educational-methodical manual in detail describes the defects of hard tissues of the teeth, the features of prosthetics by various types of artificial crowns, bridges, restoration of damaged teeth with pin constructions. Techniques of prosthetics using CAD/CAM technologies are described. Considerable attention is paid to prosthetics with partial removable plate and clasp prostheses with fixation with the help of clasps and attachments.

    PURPOSE OF THE STUDY: The purpose of this in vitro study was to comparatively evaluate the shear bond strength between repair composite resin bonded to bilayered and monolithic ceramic restorations. MATERIAL AND METHODS: Twenty two wax patterns were fabricated from customized stainless jig (5mm in height for monolithic group and 3mm in height for bilayered group with 10mm diameter and 4 mm diameter central defect with 5mm height). The samples were divided into 2 groups with each group comprising of 11 samples. Group I wax patterns were heat pressed Lithium disilicate ceramic with dimension as 3 mm in height, 2 mm layer of layering ceramic (IPS emax Ceram Powder Dentin, Ivoclar vivadent, Schaan, Liechtenstein) 10 mm diameter and 4 mm diameter with 5 mm height central defect (IPS emax press, Ivoclar vivadent, Schaan, Liechtenstein) and Group II wax patterns were heat press Lithium disilicate ceramic of 5 mm height with 10 mm diameter and with 4 mm diameter with 5 mm height central defect. The samples were etched with 5% HF for 20s, one sample from each group was analysed under SEM for etched surface characteristics. The remaining 20 samples were silanized, bonding agent applied and repair composite resin was filled according to the manufacturer’s instructions. The samples were then subjected to thermocycling and shear bond testing using universal testing machine and data was obtained. The data was then subjected to statistical analysis using non-parametric Mann-Whitney U test. Also mode of failure was analysed using scanning electron microscope. RESULTS: The mean shear bond value for Group I: 5.34 MPa and for Group II: 13.88 MPa. There was high statistical significant difference between the two test groups (P<0.05) CONCLUSION: Within the limitations of this study, the mean shear bond strength of repair composite resin bonded to monolithic lithium disilicate restorations is higher than that of bilayered lithium disilicate restorations
