    Abstract: The loss of gingival volume is a major challenge for dental surgeons with implant-supported fixed prosthesis manufactures, particularly from an aesthetics perspective in patients with a high smile line. Gingival tissue remodeling can help in papillae formation to avoid soft tissue surgery by reestablishing the appropriate shape and gingival contour of the tissues. This improves not only the aesthetics, but also the phonetics of the patient. This paper describes a clinical case of gingival conditioning obtained with interim implant-supported fixed partial dentures via incremental addition and adjustment of acrylic resin. The purpose of the gingival conditioning was to obtain improved aesthetics. Gingival conditioning by gradual pressure application is presented as an easy, non-traumatic technique that improves gingival aesthetics.

    Abstract: Extensive treatments can eventually be challenging. Even more so when the patient has limitations such as extensive tooth loss and skeletal changes, including overgrowth of the lower jaw. When indicated, these treatments tend to discourage patients due to the history of previous failures. Therefore, in addition to an interdisciplinary dental team composed of oral and maxillofacial surgeons, and prosthodontists, a nutrologist, a speech therapist, and a psychotherapist were involved in the treatment of this case. A 52-year-old female patient, Angle Class III malocclusion, with few teeth and extensive maxillary bone loss, attended the dental clinic of the Brazilian Association of Dentistry in Uberlândia. The treatment involved reverse planning, extraction of the dental remnants, calvarial bone grafting, placement of 6 titanium implants (Neodent) in the maxilla (upper jaw) and 5 in the mandible (lower jaw), orthognathic surgery, and installation of implant-supported fixed complete dentures in both jaws. Furthermore, psychotherapeutic and nutrologist’s interventions were necessary during the dental treatment, concluding the treatment with speech therapy. Within the limitations of this case, the multidisciplinary approach proved to be efficient. It promoted the reestablishment of the stomatognathic system functions without compromising nutrition during the periods when it was impossible to wear prostheses for better healing of the tissues.

    Abstract: Objective: To identify the ideal and/or most suitable masticatory function assessment methodology or treatment for each group of patients. Material and Methods: A survey was carried out in the MEDLINE, Science Direct, and Embase databases for articles published since 1990. The articles were initially selected by their titles and abstracts, and after application of inclusion and exclusion criteria, some were selected for full text reading. The studies were submitted to qualitative, quantitative, and bias analysis. Results: Of the 1,514 studies retrieved in the initial search, 51 were selected for complete analysis. Advantages of the test foods Optocal and Optosil included reliability and standardization capacity, while their disadvantages included high processing time and hardness. Wax was mentioned for its ease of chewing and testing speed, with the disadvantages of handling and the influence of temperature, in addition to low palatability. Chewing gum exhibited a speedy and easy way of testing, low cost, and reliability, in addition to commercial availability. Conclusion: Among the existing methodologies, those that were used in few studies or not validated require additional data, and for now, their indication is not recommended. Optocal and Optosil should be indicated for patients who do not have impaired chewing function. Chewing gum is a more suitable test food for patients with impaired chewing. Its practicality in being used in tests and evaluation of results makes it a more comprehensive indicator for different types of patients, treatments, or needs to assess masticatory function.

    Abstract: Aim: The crystallization step is required for lithium disilicate ceramics to change color, improve the mechanical properties and yield material to support mouth loading. Several furnaces could complete the crystallization process. This study evaluated the flexural and bond strength of lithium disilicate ceramics crystallized by different furnaces with the presence or not of vacum and different holding time. Methods: Forty lithium disilicate samples were divided into two groups: Programat P300 - control group with vacuum and holding time 7 minutes (CG) and FVPlus- experimental group and without vacuum and holding time 25 minutes (EG) and submitted to 2 experimental tests: 3-point flexural strength test and micro shear bond strength test (µSBS). For this test, the surface of the samples was treated and 1mm² of resin cement was applied on the surface. The samples were stored in artificial saliva over 2 time periods (24 hours: T0; 1-month storage: T1). To analyze the morphologic crystals of the ceramics tested, one representative specimen from each group were analyzed by using Scanning Electron Microscopy (SEM). Results: There was no significant difference in 3-point flexural strength test between groups CG and EG (p= 0.984). The µSBS results showed no statistical difference between groups, considering different storage time. There was no difference in the 3-point flexural strength and μSBS for lithium disilicate samples regardless of heat treatment of furnace type. The storage time had no influence on the μSBS. No differences were noted in the shape and size of these crystals when comparing the furnace analyzed by SEM images. Conclusion: Different furnaces did not influence the flexural and bond strength of lithium disilicate ceramics.

    Abstract: The purpose of this study was to analyze the influence of the setting and the presence of solid lubricant on the abutment screw surface on the flexural strength of the joint implant/abutment/screw. Forty abutments were connected to external hex implants, divided into 4 groups (n = 10): FE (titanium alloy screw threaded in the extremity), LE (titanium alloy screw with solid lubricant and thread in the extremity), FT (titanium alloy screw with threaded in all its length), and LT (titanium alloy screw with solid lubricant and thread in all its length). Through the mechanical flexural test, the implant/abutment resistance was evaluated with load applied perpendicular to the long axis in a mechanical testing machine (EMIC) under a speed of 0.5 mm/min. Data were submitted to a statistics test, and results showed statistically significant differences between the FE group and the other groups, and the FE group showed the lowest values. The LE group showed greater values than the LT group, and the values were statistically significant. According to the methodology used, it can be concluded that within noncoated titanium screws, a screw threaded along its entire length provided greater rigidity to the implant set, while with the screw containing solid lubricant, the screw threaded in all its length provided less rigidity of the implant set than screws with the thread only on the end. Among screws with the same geometry, those with the solid lubricant are statistically higher than those which do not have threads just at the end, but those with threads along their entire length do not show statistically significant differences.

    Abstract: O objetivo deste estudo foi determinar o efeito da vibração ultra-sônica na força necessária para a remoção de pinos pré-fabricados e moldados e fundidos. Foram utilizados 120 dentes, divididos em dois grupos. No grupo I foi utilizado o pino pré-fabricado metálico, Unimetric-Maillefer, de 0,8 mm; no grupo II foi utilizado o pino em liga de cobre-alumínio com 0,8, 1,0 e 1,2 mm de diâmetro. Os canais radiculares foram preparados com três diferentes diâmetros: 0,8, 1,0 e 1,2 mm, e com 10 mm em extensão. Os pinos foram fixados com cimento ionômero de vidro, resultando em 20 espécimes para cada subgrupo. Metade da amostra foi submetida à vibração ultra-sônica durante três minutos, enquanto a outra metade não recebeu nenhuma vibração. Os espécimes foram submetidos a uma carga de tração axial em uma máquina de testes universal. Os resultados foram analisados por testes não-paramétricos: U de Mann-Whitney, Wilcoxon e Kruskal-Wallis. A aplicação da vibração ultra-sônica reduziu significativamente a retenção promovida pelo cimento ionômero de vidro na fixação dos pinos intra-radiculares. A ação ultra-sônica foi efetiva tanto nos pinos pré-fabricados como nos pinos moldados e fundidos. A efetividade da vibração ultra-sônica não foi relacionada à linha de cimentação ou ao diâmetro do pino.

    Abstract: Um ajuste inadequado na interface pilar/implante pode gerar problemas mecânicos e biológicos. Etapas laboratoriais podem induzir a um desajuste em tal interface quando pilares do tipo UCLA calcináveis são utilizados. Este estudo propôs-se a avaliar comparativamente o desempenho de três laboratórios de prótese dentária (Labs A, B e C) pela análise do ajuste vertical de pilares UCLA calcináveis durante o processo de fundição e solda de uma mesma prótese. Quatro próteses fixas foram confeccionadas por cada laboratório utilizando pilares do tipo UCLA calcinável. A avaliação foi feita em microscopia eletrônica de varredura sob aumento de 500 x nas faces mesial e distal de cada elemento da prótese, totalizando 24 medidas por laboratório. Os resultados foram analisados estatisticamente pelo teste de Kruskal-Wallis (p 〈 0,05). Na fundição, os valores apresentados pelos laboratórios diferiram estatisticamente (p=0,004). Após a análise da solda, os valores não apresentaram diferença significante entre os laboratórios (p=0,948). Pode-se concluir que os valores de ajuste obtidos no estágio de fundição de pilares UCLA, podem ser influenciados quando processados por diferentes laboratórios e que o processo de solda convencional, por si só, aumenta o grau de desajuste da infra-estrutura, independente do laboratório que a realizou.

    Abstract: The aim of this study was to compare vertical and horizontal adjustments of castable abutments after conducting casting and soldering procedures. Twelve external hexagonal implants (3.75 × 10 mm) and their UCLA abutments were divided according their manufacturer and abutment type: PUN (plastic UCLA, Neodent), PUC (plastic UCLA, Conexão), PU3i (plastic UCLA, Biomet 3i), and PUTN (plastic UCLA with Tilite milled base, Neodent). Three infrastructures of a fixed partial implant–supported bridge with 3 elements were produced for each group. The measurements of vertical (VM) and horizontal (HM) misfits were obtained via scanning electron microscopy after completion of casting and soldering. The corresponding values were determined to be biomechanically acceptable to the system, and the results were rated as a percentage. Statistical analysis establishes differences between groups by chi-square after procedures, and McNeman's test was applied to analyze the influence of soldering over casting (α ≤ .05). For the values of VM and HM, respectively, when the casting process was complete, it was observed that 83.25% and 100% (PUTN), 33.3% and 27.75% (PUN), 33.3% and 88.8% (PUC), 33.3% and 94.35% (PU3i) represented acceptable values. After completing the requisite soldering, acceptable values were 50% and 94.35% (PUTN), 16.6% and 77.7% (PUN), 38.55% and 77.7% (PUC), and 27.75% and 94.35% (PU3i). Within the limitations of this study, it can be concluded that the premachined abutments presented more acceptable VM values. The HM values were within acceptable limits before and after the soldering procedure for most groups. Further, the soldering procedure resulted in an increase of VM in all groups.
