ABSTRACT
3D printing technology can be used in prosthodontics to obtain detailed structures. The technique offers a possible supersession for the most conventional restorations technologies. Contemporary aesthetic restorations encounter difficulties in the consistency between the analysis and design stages and the clinical implementation stage. 3D printing transfers aesthetic designs to customize the finial restoration fabrication, which could be an appropriate optimization to the aformentioned problem. Meanwhile, 3D printing technology can be employed to manufacture target restoration space guide (TRS guide), which is a blueprint for the aesthetic ceramic restorations and presents a general functional and aesthetic situation of patients. The guidance provided by TRS guide ensures precision and minimal invasive operation in aesthetic restorations. These new digital technologies have revolutionized aesthetic rehabilitation. This paper introduces the application of 3D printing in aesthetic oral rehabilitation.

“Dental fluorosis,” a specific disturbance in tooth formation and an esthetic condition, is defined as a chronic, fluorideinduced condition, in which enamel development is disrupted and the enamel is hypomineralized. Fluorosis can be prevented by having an adequate knowledge of the fluoride sources, knowing how to manage this issue and therefore, avoid overexposure. Controlling the fluoride intake is the best preventive measure for dental fluorosis, however when this is already installed and causing esthetic problems to the patient, many treatment techniques are recommended. This article describes an esthetic rehabilitation of a case of severe fluorosis using a new system for placing direct composite veneer, the Uveneer System (Ultradent) which simulates predictable shape and symmetry of natural teeth. In cases of severe dental fluorosis, the tooth enamel usually becomes porous and tooth whitening methods are not recommended. Therefore, minimally invasive technique of direct composite veneering using facial templates is the treatment of choice as it is easy to use, enhance clinical productivity, saves time, requires minimal preparation and is cost effective.
ABSTRACT
Loss of anterior teeth in patients with diastema presents a great esthetic challenge for the prosthodontists. In cases with midline diastema and interdental spacing, the option of a conventional fixed partial denture becomes impossible to use. This is because of the excess space available for pontic, which makes the incorporation of the diastema in the planned prosthesis, a compulsion. Diastema closure in such cases with the help of conventional fixed partial denture is bound to result in esthetic failures. This article presents a case of midline diastema successfully maintained by lingual loop connectors between the pontic and the retainers to achieve esthetic rehabilitation in the mandibular anterior region.

En la actualidad el aumento de la demanda estética y la necesidad de procedimientos mínimamente invasivos ha llevado a un aumento de la técnica adhesiva. Ribbond® es una marca de fibra de polietileno que permite un eficiente traspaso de fuerzas, es virtualmente plegable y se adapta fácilmente a la morfología dentaria y al contorno del arco dentario. Dentro de sus principales características podemos encontrar: Biocompatibilidad, inerte, translúcido y durable. Dentro de la odontología se le han dado distintos usos para esta fibra, ya sea como mantenedor de espacio, puente adhesivo, poste y núcleo endodóntico, ferulización, restauraciones tipo inlay y estabilización postortodóncica. En el caso de los pacientes fisurados se ha hecho relevante el uso de Ribbond® como puente adhesivo ya que permite mejorar la estética y rehabilitar temporalmente los espacios desdentados causados por la ausencia de un incisivo, principalmente una vez terminado el tratamiento de ortodoncia y en espera de una rehabilitación definitiva, aún más cuando el paciente no ha terminado su crecimiento y desarrollo. En este artículo se presenta un caso clínico de un paciente con labio leporino y fisura velopalatina operado demostrativo de la técnica de rehabilitación con Ribbond®.
Today the increasing demand of aesthetic and minimally invasive procedures has led to a boom of the adhesive technique. Ribbond® is a polyethylene fiber that allows an efficient transfer of forces, is virtually foldable and is easily adapted to tooth morphology and dental arch contour. Among its main features we can find: Biocompatibility, inert, translucent and durable. In dentistry, different uses have been given to this fiber, whether as space maintainer, adhesive bridge, endodontic post and core, splinting, inlay type restorations and postorthodontic stabilization. In the case of cleft lip and palate patients the use of Ribbond® as an adhesive bridge has become relevant, as it improves aesthetics and temporarily rehabilitates the edentulous spaces caused by the absence of an incisor. It is used especially after completion of the orthodontic treatment and waiting for a final rehabilitation, even when the patient has not completed their growth and development. This article presents a clinical case of a patient with lip and cleft palate operated with the rehabilitation technique using Ribbond®.

Restauração de dentes tratados endodonticamente constituidesafio permanente na odontologia, uma vez que aspectos biomecânicos,estéticos e complexidade de execução técnica podemresultar em insucesso com consequente perda do elemento dentário.Geralmente dentes tratados endodonticamente se encontramenfraquecidos devido à perda de estrutura dentária o queresulta em redução de resistência mecânica da dentina. Estesfatores resultando em maiores riscos de falhas biomecânicasquando comparados aos dentes com vitalidade pulpar. Este trabalhotem por objetivo apresentar procedimentos clínicos reabilitadorespara devolução de harmonia estética com ênfase emprocedimentos realizados em incisivo central superior com extensaperda de estrutura coronária e restauração em resina compostainsatisfatória. Foi empregada a associação de pino de fibrade vidro (Exacto, Ângelus) e resina composta para reconstruçãointerna seguido de coroa em cerâmica pura (In Ceram Alumina,Vita). São destacados os passos clínicos e breve revisão de aspectosbiomecânicos e estéticos desta alternativa reabilitadora.
Restoration of endodontically treated teeth is a challenge inoperative dentistry, since the biomechanical, aesthetic and complexityof the technique can result in failure with subsequenttooth loss. Generally endodontically treated teeth are weakeneddue to loss of tooth structure and reduce the mechanicalstrength of dentin. These factors result in a higher risk of biomechanicalfailure when compared to teeth with pulp vitality.This paper aims to present clinical rehabilitation procedures torecover the smile harmony with an emphasis on aesthetic proceduresperformed in the maxillary central incisor with extensiveloss of coronal tooth tissue and unsatisfactory compositeresin restoration. It was employed the combination of fiberglasspost (Exacto, Angelus) and coronal reconstruction with compositeresin followed by all ceramic alumina crown (In CeramAlumina, Vita). Highlights the clinical steps and brief review ofbiomechanical and aesthetic rehabilitation of this alternative aredescribed.
