ABSTRACT
Objective@#To present our in-house 3D planning protocol utilizing open-source computer-aided design software and discuss specific applications in reconstruction of various craniomaxillofacial defects, demonstrating a free, accessible, efficient, accurate, and easily learnable alternative to expensive counterparts. @*Methods@#Design: Case Series. Setting: Tertiary Private Training Hospital. Participants: Ten (10) patients who underwent CAD assisted reconstructive surgeries from February 2017 – May 2018.@*Results@#A total of 10 patients were included; 7 mandibular reconstructions were surgically reconstructed using our 3D planning protocol and achieved symmetric mandibular contour, with good functional occlusion after surgery; 1 cranioplasty and 1 orbital trauma case also achieved good symmetry and adequate correction of enophthalmos respectively. However, inadequate soft tissue correction was seen in 1 case of maxillary reconstruction despite achieving symmetric bony contour. @*Conclusion@#Our 3D planning protocol using open-source CAD applications is a viable alternative to expensive professional counterparts. Additional prospective studies may better demonstrate benefits in terms of accuracy and decreasing intraoperative time in craniomaxillofacial and head and neck reconstruction.

Computer-Aided DesignABSTRACT
Atualmente, a busca pela estética tem aumentado a procura por tratamento ortodôntico na população adulta. A agenesia dentária tem uma grande influência na estética do sorriso. Consequentemente, na harmonia da face, a ausência dos incisivos laterais contribui de maneira significativa. Dentre as várias formas de tratamento, pode-se optar pelo fechamento de espaço, com substituição do incisivo lateral pelo canino ou abertura de espaço para uma posterior reabilitação implantoprotética. Neste artigo, foi descrito o tratamento da agenesia dos incisivos laterais superiores e revisadas na literatura as suas possibilidades de tratamento, com enfoque na abertura do espaço associado ao planejamento 3D e reabilitação estética através da reabilitação implantoprotética
Nowadays, the seek for aesthetics has been the subject of increased demand for orthodontic treatment in adults. The tooth agenesis has a great influence on the smile esthetics and consequently the harmony of the face, which is significantly affected by the absence of lateral incisors. Among the various treatment forms, the clinician can decide for space closure with replacement of the lateral incisor or canine space opening for later prosthetic implant rehabilitation. In this article we described the treatment of agenesis of the maxillary lateral incisors and made a literature review about the treatment options, focusing on space opening associated with the planning and 3-D aesthetic management through the prosthetic implant rehabilitatio

O propósito deste trabalho foi apresentar aspectos favoráveis ao uso de implantes curtos nas situações de limitações de altura e volume ósseo em mandíbulas atróficas, onde o tratamento com este tipo de implante torna-se viável. Uma paciente que optou pelo tratamento com implantes curtos, depois de uma grande procura para reabilitação de uma mandíbula com significativa perda óssea e grande instabilidade de suas próteses. Depois dos exames clínico e radiográfico, foram instalados seis implantes Titamax CM na região anterior inferior entre 33 a 43, sendo cinco implantes de tamanho 7 mm e um de 8 mm como base para a confecção de uma prótese total fixa tipo protocolo. Depois do período de espera para a osseointegração, realizou-se a reabertura e, através do aparelho Osstell, verificou-se a alta estabilidade dos implantes com o osso, pré-requisito para a garantia do sucesso na reabilitação implantossuportada. Após três meses houve a troca da prótese total convencional superior e a elaboração de uma prótese fixa protocolo inferior. Foram feitos alguns acompanhamentos semestrais e a paciente apresenta excelente resultado clínico há mais de cinco anos...
The purpose of this study is to promote the use of short implants in situations of limited height and bone volume in atrophic mandibles, whereas treatment with this type of implant becomes feasible, showing a patient that has chosen a treatment with short implants, after spending a long time in search for the best possibilities in a mandible with signifi cant bone loss and the instability of her prostheses. After clinical and radiographic examination, six Titamax CM implants were installed in the lower anterior region between 33-43, seeing that five of them were at the size of 7 mm and one of 8 mm serving as foundation for a future fixed total prosthesis. After the waiting period for osseointegration, a high stability was verified with the aid of Osstell, being a prerequisite for ensuring the successful implant-supported rehabilitation. Three months later, a conventional total prosthesis was placed along with the elaboration of a lower fixed prosthesis. Regular follow-ups were made at each six months and the clinical results are excellent after 5 years...
