When the angle of installation of the additional implant is less than 25 degrees and that of the conventional zygomatic implant is less than 39 degrees , perforation of the maxilla, zygoma, or the infratemporal fossa must be avoided. When the angle of installation of an additional implant is greater than 47 degrees and that of the conventional zygomatic implant is greater than 62 degrees , perforation of the orbital floor must be avoided. The length of an additional implant was greater than the length of a conventional zygomatic implant, and should be measured prior to drilling, because the greatest value found for this distance was 61.94 mm, while the maximum length of the zygomatic implants currently available on the market is 52.5 mm.

SUMMARY:The parotid is the largest salivary gland in humans producing an essentially serous secretion, which normally reaches the oral cavity through a sole duct (the parotid duct) after the latter making its way through the buccinator muscle to reach the mucosa lining the mouth at the level of the cheek. The present study reports on a rare case of double parotid duct found during the dissection the right side of the face of a cadaver of a 46-year-old male individual. The superior (D1) and inferior (D2) ducts were 26.49 mm and 37.25 mm long, respectively. Based on the diameter of both ducts (D1 and D2) taken in the posterior (3.05 mm and 2.84 mm, respectively) and mid (2.84 mm and 2.68 mm, respectively) thirds, as well as on the histological findings, both ducts were considered to be main parotid ducts. These two ducts merged at the level of the anterior third forming one sole opening into the oral cavity. The data hereby reported are relevant to the various clinical and surgical procedures involving the parotid gland.

Introdução: os dentes artificiais de resina acrílica são amplamente utilizados na confecção de próteses, por apresentarem propriedades físicas, mecânicas e biológicas, além de características de fácil manuseio. No entanto, devido sua característica de baixa resistência à abrasão, a escovação pode levar à perda de massa dos dentes artificiais e aumento da rugosidade. Objetivo: avaliar de forma qualitativa a rugosidade superficial e polimento de dentes artificiais das marcas Hereaus Premium; Trilux e Vita, após período de 1 ano de escovação, com fotografias em Lupa Estereoscópica. Metodologia: para a realização deste estudo, serão utilizados 10 dentes artificiais de cada marca comercial (Trilux, Vita e Hereaus Premium). Os dentes serão fixados com resina ortoftálica em tubo de PVC de 15 mm de espessura. Para o teste de abrasão, será usada uma máquina de escovação simulada com escovas de dentes de cerdas macias e solução de pasta de dente. As imagens serão obtidas com câmera digital acoplada a lupa estereoscópica. A rugosidade superficial e o polimento serão analisados antes da escovação simulada e após 12 meses de escovação através das imagens. Resultados: após o teste de abrasão foi observado a presença de um desgaste superficial e/ou ranhuras na superfície dos dentes artificiais em todos os grupos. Porém não houve um padrão similar entre os corpos de prova de um mesmo grupo. Conclusão: Pode-se concluir que a escovação provocou o aumento da rugosidade superficial e alteração no polimento em todos os dentes artificiais utilizados.

Monitoring in universities and university centers aims to initiate students in teaching and contribute to the improvement of undergraduate education through the articulation of theoretical and practical content, thus favoring the production of knowledge under the guidance of the teacher responsible for a specific curricular component. Monitoring allows students to develop skills associated with teaching and deepening their knowledge; however, there are elements that can hinder this practice, such as the conciliation of monitoring activities with regular academic activities. The objective of this study is to analyze the contribution of monitoring to learning and academic training in the Dentistry Course at UFBA. The sample of this research was composed of 34 students of both sexes, all in the condition of student-monitors of the Faculty of Dentistry at the Federal University of Bahia (UFBA), city of Salvador, Bahia, Brazil. A quantitative questionnaire was applied to students in order to analyze various aspects on the monitoring practice. Students interviewed believed that monitoring is relevant for academic training and that this activity brings greater learning during its performance. Of all respondents, 94% believe that monitoring is relevant in initiating students in higher education teaching. Most interviewees reported that they have good relationship with the Advisor Teacher and with monitored students. Monitoring gives the student the opportunity to develop skills and competences associated with teaching, provides personal and professional growth and qualifies the curriculum of those who participate in this process.
