Patients are looking for esthetic and functional changes when seeking orthodontic treatment and expect the remaining of a stable occlusion. Occlusion stability is one of the goals of the orthodontist; however, dental relationships changes in long-term can occur leading to a relapse of the treatment. Teeth and shape of arches tend to return to the original form, been the retention phase important after the appliance removal, even after several years of post-treatment. This article approaches a submission of a clinical case of Class II division 1 treated with extraction of premolars analyzing its long-term stability.

The early malocclusion treatment has increased interest of orthodontic community. Among these is the serial extraction that harmonizes the differences between the amount of dental material and permanent deficiency of supporting bone. The technique is applied in mixed dentition through a predetermined sequence of extractions between deciduous and permanent teeth, in order to reach spontaneous immediately alignment of remaining permanent teeth with a minimum orthodontic mechanics. It will be reported a case where the serial extraction was performed in a growing patient with biprotrusion, Class I malocclusion and severe crowding. All functional and aesthetics goals were reached.

The correction of a Class III malocclusion in adult patients is one of the major challenges in orthodontics due to facial deformities occurring during the unfavorable growth of this kind of pattern, as well as the treatment options capable of producing facial changes aesthetically acceptable and adequate for today's beauty standards. One acceptable alternative treatment is the removal of a lower incisor. For a Class III correction through a lower incisor extraction a thorough analysis and planning must be carried out by taking into consideration the amount of overjet and overbite, periodontal condition of the teeth and the possibility of obtaining a good dental occlusion with acceptable facial aesthetics. Will be presented two case reports of patients presenting an anteroinferior crowding, Class III malocclusion condition. The treatment through a lower incisor extraction and the reasons why this treatment was adopted will be discussed.

Introduction: the oral rehabilitation in edentulous patients using removable complete dentures is a classic treatment, easily accessible, and presenting satisfactory results. However, to succeed in this type of treatment, stability is an extremely important factor. The neutral zone technique for the production of complete dentures determines the oral cavity space for the positioning of teeth and denture base that provide a neutralization of the forces delivered by lips, cheeks, and tongue, providing better stability and retention of prostheses, which is indicated in cases with history of difficulties in adapting the conventional mandibular denture. Objective and case report: this paper aimed to describe a clinical case report of the oral rehabilitation of a patient with paraprosthetic muscles hypertonicity through removable complete dentures produced by the neutral zone technique, using condensation silicone. Final considerations: the use of condensation silicone for the development of the neutral zone technique showed to be a good alternative for the development of this clinical case, providing satisfactory stability and retention of the complete mandibular denture.

Objective and Case report: The purpose of this paper is to describe the neutral zone technique in a patient with oral deformity on the right labial commissure due to the resection of an oral cancer, enhancing the difficulty resulting from mouth limited opening and the use of tissue conditioner material to determine the neutral zone. Complete denture was obtained through this technique, providing good retention and stability which made functional rehabilitation feasible to patient of his or her masticatory function. Final considerations: The neutral zone technique in complete dentures will determine a specific intraoral area for tooth position and denture base contour where the forces generated by lips, cheeks and tongue are neutralized. The objective of this technique is to provide an alternative approach for patients who presented an historic instability of lower complete denture: atrophic ridge, oral deformities and also with disorder problems. An oral rehabilitation using this technique improves comfort to the patient providing retention and stability of mandibular complete dentures.

A catarata é a afecção da lente mais comum em cão, caracterizada por uma opacidade do cristalino e alteração de comportamento devido ao déficit visual. O exame oftálmico adequado e completo da lente permite a classificação adequada da catarata auxiliando na escolha do melhor tratamento de cada paciente. O tratamento preconizado para a catarata é o procedimento cirúrgico, que associado com o uso de anti-inflamatórios, midriáticos e antibióticos pré-operatórios e pós-operatórios melhoram os resultados visuais e previnem algumas complicações. A remoção da lente pode ser feita pelas técnicas de discisão, extração intracapsular, extração extracapsular e facoemulsificação, sendo que a escolha correta da técnica para cada caso contribui para o sucesso do procedimento e diminui as complicações pós-operatórias, porém as técnicas de escolha para a remoção da catarata são a extração extracapsular e a facoemulsificação. O objetivo da revisão sistemática é comparar as complicações de duas das técnicas para extração da catarata, extração extracapsular e facoemulcificação, ressaltando qual a técnica que apresentou menores complicações em cães. Foram analisados dez artigos pesquisados nas bases de dado PubMed e Google Acadêmico, sendo complementados com o uso de livros. Foram encontradas como complicações perda da visão, glaucoma, descolamento de retina, hemorragia intraocular, ruptura da cápsula posterior, alterações corneanas, endoftalmites, sinéquia posterior, fotofobia, blefaroespasmo e hiperemia conjuntiva. Essas complicações foram descritas em ambas as técnicas, porém inúmeros fatores
