RESUMO

Este relato descreve o caso de uma paciente jovem que necessitou de reabilitação na região maxilar anterior devido a insatisfações estéticas. O artigo objetivou relatar a sequência clínica da reabilitação de um implante pré-existente na região do dente 21 com UCLA de zircônia personalizável e coroa de dissilicato de lítio associada a instalação de facetas de dissilicato de lítio dos dentes 15 ao 25 para harmonização do sorriso. Previamente ao tratamento reabilitador, foi realizado o planejamento do caso que incluiu a necessidade de gengivectomia e condicionamento do perfil de emergência na região peri-implantar. Após a cicatrização, foram confeccionados preparo minimamente invasivos de acordo com as informações do mock-up. UCLA personalizável de zircônia foi selecionada como componente protético, visando a estética do caso. Para a moldagem, utilizou-se transfer de moldeira aberta para cópia do perfil de emergência e posicionamento do implante na região do 21 e moldagem simultânea com silicone de adição. Após a prova, a cimentação das facetas de dissilicato de lítio foi realizada com cimento adesivo fotopolimerizável. Os resultados estéticos e funcionais foram satisfatórios. No presente caso clínico, conclui-se a importância da abordagem multidisciplinar para alcançar resultados satisfatórios. Ademais, a associação das facetas e a coroa de dissilicato de lítio implantossuportada com UCLA de zircônia personalizável proporcionou os resultados estéticos e funcionais da paciente(AU)

RESUMO

Os pilares personalizados são usados em reabilitações protéticas sobre implantes quando há exigências de angulação, perfil de emergência e margem gengival, em que os pilares convencionais não conseguem reabilitar de forma correta os conceitos de forma, função e estética. Através de um relato de caso clínico, onde houve a reabilitação dos elementos 21 e 22, com o uso de implante e próteses, usando o pilar personalizado em zircônia sobre o implante do 22, confeccionado com a tecnologia CAD/CAM. Esse sistema de pilares personalizados oferecem o desenho mais próximo do ideal e o ajuste mais perfeito em relação ao implante e ao tecido gengival, além de considerar as vantagens e desvantagen em relação aos pilares convencionais pré-fabricados nas questões de tempo de tratamento, custos e resultado estético e biológico. Concluimos que a reabilitação com pilares personalizados CAD/CAM confere uma excelente alternativa reabilitadora, devolvendo função e estética aos pacientes, desde que haja conhecimento adequado por parte dos profissionais envolvidos(AU)

RESUMO

Parotid gland tumor is the most common salivary gland tumor and surgery is the main treatment method. The conventional surgery for the treatment of parotid tumor is mostly performed by using large incision which often causes complications and aesthetic problems to patients. With the advancement of medical technology, deeper understanding of histopathology and anatomy by the surgeons, as well as patients' higher demands on aesthetics and functions, the surgical methods and incisions have been constantly improved. This review focuses on the evolution of surgical approaches and incisions for the treatment of parotid tumors and provides an outlook based on the preliminary application of endoscopically assisted parotid tumor resection.

RESUMO

OBJECTIVE: The aim of this experimental in vitro study was to evaluate whether dental bleaching performed before orthodontic treatment change the shear bond strength (SBS) of monocrystalline and polycrystalline esthetic brackets. METHODS: Sixty (60) bovine incisors teeth were used and randomly divided into the following six groups (n=10): SCP (without bleaching/polycrystalline brackets); SCM (without bleaching/monocrystalline brackets); 1CP (one bleaching session/polycrystalline brackets); 1CM (one bleaching session/monocrystalline brackets); 3CP (three bleaching sessions/polycrystalline brackets); and 3CM (three bleaching sessions/monocrystalline brackets). The brackets were bonded seven days after the bleaching sessions. The samples were submitted to the SBS test in a universal testing machine (Instron model 4411) at 1 mm/min crosshead speed. The two-way analysis of variance (ANOVA) and the Tukey tests were performed at a 5% level of significance. After the mechanical test, samples were evaluated to determine the adhesive remnant index (ARI). RESULTS: The SBS values were significantly higher for the monocrystalline brackets, when compared with the polycrystalline type (p< 0.0001), and significantly higher with three bleaching sessions than without bleaching (p< 0.0436). The ARI showed predominance of failures between the bracket and resin for all the groups (score 3). CONCLUSION: Three dental bleaching sessions increased the SBS values. Monocrystalline brackets showed higher SBS values than the polycrystalline type.

RESUMO

INTRODUCTION: Having a beautiful smile is the main desire of people seeking dental treatment. To achieve this goal, many variables must be considered. These include tooth alignment, color, shape and size, besides their harmonious relationship with the lips and face. An individualized diagnosis is essential to achieve the best result. Within this context, facial analysis and the characteristics of shape, size and position of maxillary incisors play a key role. METHODS: This paper describes clinical situations in which interdisciplinary treatment was performed to achieve esthetic results in a conservative manner and ensuring greater stability. In most cases requiring reshaping of maxillary incisors for esthetic reasons, prior orthodontic movement is essential. The main focus of this paper is to discuss the many variables involved in these situations. RESULTS AND CONCLUSION: The results of treatments described in this paper were obtained by means of a multidisciplinary approach, involving Orthodontics and Esthetic Dentistry, acting in harmony and recognizing their possibilities and limitations, in order to offer patients the best esthetic solution for their smile. The best treatment option is not always the easiest or fastest. The dentist, as a health professional, should consider the patients' wishes but also perform treatments with minimal intervention, and the best and most predictable esthetic result, also focusing on function and health.

RESUMO

PURPOSE: The purpose of this study was to investigate the patient satisfaction and the clinical effect of biofunctional complete denture via questionnaire survey. METHODS: Fifty-six patients(26 males and 30 females) with biofunctional complete denture were asked to fill in a questionnaire about satisfaction and the type-variety of food after repair for 1 week, 1 month and 3 months during regular follow-up visits or telephone visits. SPSS 26.0 software package was used to analyze the data. RESULTS: After 3 months of wearing bio-functional complete denture, the average score of the five indicators of aesthetic degree, speech function, chewing function, retention function and comfort level of the patients were >6, reaching the level of "satisfactory" or "fair"; among which the aesthetic degree was the highest (7.71±1.46). The food type score reached 33.96±1.21 at the third month. Repeated measures ANOVA showed that each group of indexes changed significantly over time (P<0.05). Except that the mean value of aesthetics score was equal at 3 months and 6 months, the other indexes all increased along time. Among 56 patients, two had 5 or more times of modification due to pain, accounting for 3.57%. CONCLUSIONS: Bio-functional complete denture can achieve good clinical effect in the early stage of denture repair in patients with dentition loss.

RESUMO

INTRODUCTION: Anterior synostotic plagiocephaly recognizes the synostosis of one of the hemicoronal sutures as a cause and can manifest itself with varying degrees of severity. Clinically it presents a reduction of the sagittal growth of the affected side and flattening of the frontoparietal complex. MATERIALS AND METHODS: The authors retrospectively examined our case sample dividing it into 3 groups based on the Di Rocco classification. For each category, we assessed the extent of facial alterations at the end of skeletal growth and retrospectively analyzed the surgical options aimed at correcting aesthetic and skeletal deficits. RESULTS: The authors found that predictable results could be obtained by standardizing the surgical procedure based on Di Rocco's classification groups; in particular, the authors achieved satisfactory results by assigning a specific surgical procedure to each class.

RESUMO

ABSTRACT: The present study aimed to investigate how "Gull in Flight" appearance and alar-columellar relationship change following maxillary surgery. Thirty-three patients who underwent Le Fort I osteotomy with or without mandibular osteotomy were included in this retrospective study. Measurements which were angle of columella triangle, alar-rim angle, columella lobular angle, and distance of points forming "Gull in Flight" appearance were evaluated on pre and postoperative frontal and lateral photos of patients. Data was submitted to statistical analysis and significance level was determined as 0.05. Following Le Fort I surgery, distance of points forming "Gull in Flight" appearance with respect to canthus was decreased significantly (P < 0.05). Positions of these points to each other were not changed (P > 0.05). Every 1 mm maxillary impaction led to 0.58 mm reduction in y3 (the distance from the point that illustrates Gull's body) (P = 0.032). There was a decrease in angle of columella triangle, alar-rim angle and increase in columella lobular angle. However, these changes were not found significant (P > 0.05). Angle of columella triangle was increased 2.51 degree for every 1 mm maxillary advancement (P = 0.028). In conclusion, maxillary surgery had an impact on nasal region from frontal view. However, "Gull in Flight" appearance which is one of the aesthetic parameters in nose was not changed following maxillary surgery.

RESUMO

In this case of a comprehensive dental restoration, a predictable course of treatment is demonstrated in which dental risk was stabilized and definitive treatment was provided in a phased approach to accommodate financial limitations of the patient. Utilizing digital photographic analysis, facial reference glasses, and intraoral scanning, the clinician implemented a treatment plan that was aimed at minimizing and managing the patient's biomechanical and functional risks and resolving his concerns about past failing dental work and an unattractive smile. The phased rehabilitation plan included opening of the vertical dimension of occlusion to accommodate restorative space, appropriate incisal edge position, and function.

RESUMO

PURPOSE: The purpose of this cone beam computed tomography (CBCT) study was to investigate the probability of using straight screw-channel screw-retained restorations following an immediate implant placement and provisionalization protocol in maxillary anterior teeth utilizing implant planning software. MATERIALS AND METHODS: A retrospective review of CBCT images was done. The midsagittal images of maxillary anterior teeth (right canine to left canine) were created in implant planning software, screen-captured, and transferred to a presentation program. The digital implant templates were created for 3.5-mm-diameter (used for central and lateral incisors) and 4.5-mm-diameter (used for central incisors and canines) tapered implants with lengths of 13, 15, and 18 mm. The frequency percentages of immediate implant placement and provisionalization and immediate implant placement and provisionalization with straight screw-channel screw-retained restorations were recorded and compared among all maxillary anterior teeth. RESULTS: CBCT images from 1,200 teeth were evaluated. The overall frequency percentages of immediate implant placement and provisionalization and immediate implant placement and provisionalization with straight screw-channel screw-retained restoration were 84% (range = 74% to 92%) and 14% (range = 10% to 24%), respectively. CONCLUSION: Although the probability of being able to employ immediate implant placement and provisionalization with a straight screw-channel screw-retained restoration in the esthetic zone is low, the use of smaller-diameter implants can substantially increase the probability.

RESUMO

Nowadays, the objective of esthetic rehabilitation is not only to guarantee the results to the patients in terms of esthetic parameters but also the possibility to show the pre-visualization of possible results and therapy planning. OBJECTIVE: The aim of this study is to apply the 3D-DPS digital planning technique, in the prosthetic treatment of a patient, to produces digitally the mockup for the digital previewing and esthetic crown and veneer for the final prosthetic treatment. MATERIALS AND METHODS: A case report participant is a young patient, a female, 26 years old, with no oral, periodontal, or systemic diseases. After a sign of an informed consent and an explication of a plan of treatment, technical intraoral and extraoral pictures and intraoral digital impressions were taken. The digital images improved from the 2D Smile Lynx Software and the scanner stereolithographic (STL) file was matched into the CAD Lynx to obtain a virtual previsualization of teeth and smile design. Then, the mockup was milled using a CAM system. Minimally invasive preparation was carried out on the enamel surface with the mockup as position guides. Finally, the esthetic CAD-CAM veneer and crown were produced digitally using the CAD Wax as a guide. RESULTS: The use of the digital project and the pre-operative mockup allowed a perfect initial evaluation and a better understanding of the patient's treatment plan. CONCLUSIONS: The 3D digital planning technique is a new, predictably and minimally invasive technique. It allows diagnosis and a better communication with the patient. It helps to reduce the working time and the possible errors usually associated with the classical prosthodontic manual step.

RESUMO

The objective of this study was to explore dental students' facial profile preferences in a large sample of students. Nine hundred and nineteen dental students of four dental schools were involved. As part of a larger study on dentofacial esthetics, six photo series consisting of one unaltered and four altered variants of the same female profile were distributed among the students. The altered features were ones that are esthetically significant according to the literature. The students had to indicate the photo in each series that they preferred. The data were analyzed in a regression model in which preference in the given photo series was the dependent variable and gender, grade of studies, and dental school were the factors. Eight hundred and sixty-one students (93.7%) responded. Gender and dental school were not associated with the observed preferences, but the grade of studies was associated for three of the modified parameters: chin prominence, the sagittal position of the maxillary dental arch, and the simultaneous modification of the prominence of the chin and the nose. This study has confirmed several earlier observations, and new observations have also been made. We have demonstrated that the anteroposterior position of the maxillary incisors may be an important determinant of profile esthetics, even if this position does not influence the situation of the soft tissues and if the forehead cannot be used as a reference. We have also shown that the harmony between the nose and the chin overrides the importance of their individual dimensions.

RESUMO

PURPOSE: To assess hard and soft tissues regenerated around immediate implants placed in compromised fresh extraction sockets using vestibular socket therapy 2 years postoperatively. MATERIALS AND METHODS: Twenty-seven compromised fresh extraction sockets were managed using vestibular socket therapy and immediate implant placement. After immediate implant placement, a cortical bone shield was stabilised through a vestibular incision. The socket defect was filled with particulate bone graft. Labial plate thickness and bone height were evaluated 1 and 2 years postoperatively using CBCT. The pink aesthetic score and probing depth were recorded after 6 months, 1 year and 2 years. A Friedman test was used to study changes in the reported outcomes over time, with the level of statistical significance set at P ≤ 0.05. RESULTS: All implants recorded a 100.0% survival rate. A statistically significant increase in bone height (0.93 mm, P = 0.004) and apical (0.12 mm, P = 0.026), midfacial (1.26 mm, P < 0.001) and crestal (0.86 mm, P < 0.001) bone thickness was observed after 2 years. The changes in pink aesthetic score and probing depth were not significant: the pink aesthetic score was 12.48 ± 1.45 and the mean PD was 2.37 ± 0.79 mm mesially, 2.11 ± 0.70 mm facially, 2.07 ± 1.04 mm distally and 1.00 ± 0.00 mm palatally after 2 years. CONCLUSION: Combining immediate implant placement with vestibular socket therapy to manage compromised fresh extraction sockets offers promising radiographic, aesthetic and periodontal results while minimising the treatment time and number of surgical procedures required.

RESUMO

AIM AND OBJECTIVE: The aim of this study was to evaluate the extent of microleakage beneath stainless steel orthodontic brackets bonded with different adhesive systems. MATERIALS AND METHODS: Freshly extracted 60 human premolar teeth from mandibular arch were included in this study. After sterilizing all teeth, they were stored in thymol solution of 1% for further preparation. Acrylic blocks were used to mount the teeth in a way their roots were totally implanted up to the cement enamel junction in acrylic with crown being visible. A 0.022 slot, stainless steel preadjusted edgewise premolar brackets were taken. Sixty premolars were categorized randomly into three groups (20 premolars in each group) as follows: group I: flowable composite, group II: Fuji Ortho LC, group III: Transbond XT. Later, all the samples were subjected to thermocycling and tested immediately and 24 hours after water storage. The samples were submerged for 24 hours in methylene blue solution (2%) at room temperature. A ×20 magnification stereomicroscope was used to examine all samples. RESULTS: The lowest microleakage (1.34 ± 0.20) was shown by Transbond XT restored teeth, followed by flowable composite group (1.79 ± 0.32) and Fuji Ortho LC group (2.98 ± 0.13). An analysis of variance showed statistically significant differences among various adhesive systems. A statistically significant difference (p <0.05) among groups I and II, and groups II and III adhesive materials was seen. CONCLUSION: This study demonstrated microleakage in all the examined adhesive groups but the lowest microleakage was found with Transbond XT group followed next by Filtek Z350 XT group and Fuji Ortho LC group. CLINICAL SIGNIFICANCE: Due to microleakage, the bacteria and fluids present intraorally penetrate through the gaps along the enamel-adhesive boundary. This penetration results in significant esthetic and clinical complications. Such problems related to microleakage can be addressed with the use of an appropriate adhesive agent.

RESUMO

This case report describes the treatment of a 29-year-old woman with facial asymmetry and 2 hopeless teeth. Her lower dental midline was shifted to the left side, and the mandibular left second molar would need to be extracted because of severe caries. The maxillary right second premolar was root rest, and the upper dental midline was shifted to the right side. Because of the patient's asymmetry and Class III skeletal pattern, a severe Class III relationship in the right canine region and lingual crossbite in the left side was observed. She did not want jaw surgery. The mandibular right first premolar, 2 hopeless teeth, and maxillary left second premolar were extracted, and orthodontic mini-implants were used to correct the dental midline, crossbite, and crowding. The mandibular left third molar was moved to the second molar extraction space by using orthodontic mini-implant anchorage. Adequate functional and esthetic results were obtained. Correction of the crossbite on the left side could improve facial asymmetry by changing the drape of the overlying lips.

RESUMO

As dental composite materials have evolved, their properties and overall quality have improved. New composites can be ideal for simplifying highly esthetic, long-lasting, minimally invasive restorations in a timely manner. This article presents two cases in which a universal composite with a chameleon effect was used in anterior restorations to achieve exceptional blending and a natural-looking appearance with the adjacent dentition. The cases demonstrate techniques for enhanced cosmetic dentistry.

RESUMO

O objetivo do estudo foi realizar uma revisão narrativa da literatura para comparar os métodos visual e instrumental de seleção da cor dentária, correlacionando-os com o fator experiência e a educação continuada. Utilizou-se como base de dados a MEDLINE na qual foram aplicados os descritores "visualshade match", "color measurement", "spectrophotometer" e "tooth color determination". Os critérios de inclusão foram artigos publicados entre 2010 e 2020que abordassem uma análise comparativa entre as duas modalidades de seleção da cor dentária. Se enquadraram nos critérios de exclusão estudos que não contemplavam a temática abordada e aqueles publicados nos anos anteriores a 2010, além das revisões de literatura. No total, onze artigos foram selecionados para compor essa revisão. Os estudos demonstraram que o método instrumental apresentou maior confiabilidade e reprodutibilidade quando comparado ao método visual, isso se deve ao fato de a escolha de cor através de instrumentos eletrônicos proporcionar melhor precisão e atenuação da subjetividade. No que concerne a experiência como fator influenciador da seleção de cor, os estudos são controversos. Mesmo evidenciando melhor precisão, a estimativa instrumental apresenta limitações devido à dificuldade de aferição em função da convexidade da anatomia dentária. Desse modo, foi descrito que a associação de métodos é capaz de elevar a confiabilidade da escolha de cor, melhorando o resultado estético. Não houve consenso entre os estudos com relação à influência da experiência, no entanto, a educação continuada foi sugerida na literatura como alternativa para formar profissionais mais confiantes no processo de seleção de tonalidades(AU)


The goal of this study was to carry out a narrative review of the literature to compare the visual and instrumental methods of tooth color selection, correlating them with the experience factor and continuing education. MEDLINE was used as a database in which the descriptions such as "visual shade match", "color measurement", "spectrophotometer" and "tooth color determination" were applied. The inclusion criteria were articles published between 2010 and 2020 that addressed a comparative analysis between the two types of tooth color selection. The exclusion criteria included studies that did not contemplate the theme addressed and those published in the years prior to 2010, in addition to literature reviews. In total, eleven articles were selected to compose this review. Studies have shown that the instrumental method showed greater reliability and reproducibility when compared to the visual method, this is due to the fact that the color's choice through electronic instruments provides better precision and lessened subjectivity. Regarding experience as na influencing factor in color selection, studies are controversial. Even with better precision, the instrumental estimation has limitations due to the difficulty of measuring it due to the convexity of the dental anatomy. Thus, it was described that the association of the methods is able to increase the reliability of the color's choice, improving the aesthetic result. There was no consensus among the studies in regard to the experiment's influence, however, continuing education was suggested in the literature as an alternative in order to form more confident professionals when it comes to the shade selection process(AU)
