Reabilitação oral de paciente com sequela cirúrgica utilizando a técnica da zona neutra: relato de caso clínico

Objective and Case report: The purpose of this paper is to describe the neutral zone technique in a patient with oral deformity on the right labial commissure due to the resection of an oral cancer, enhancing the difficulty resulting from mouth limited opening and the use of tissue conditioner material to determine the neutral zone. Complete denture was obtained through this technique, providing good retention and stability which made functional rehabilitation feasible to patient of his or her masticatory function. Final considerations: The neutral zone technique in complete dentures will determine a specific intraoral area for tooth position and denture base contour where the forces generated by lips, cheeks and tongue are neutralized. The objective of this technique is to provide an alternative approach for patients who presented an historic instability of lower complete denture: atrophic ridge, oral deformities and also with disorder problems. An oral rehabilitation using this technique improves comfort to the patient providing retention and stability of mandibular complete dentures.

Estudo prospectivo sobre a utilização de próteses totais implantossuportadas em pacientes edêntulos

The objective of this study was to evaluate the impact of replacing conventional mandibular complete dentures by complete fixed dentures on the oral health-related quality of life and kinesiographic parameters of maxillary edentulous patients. Material and Methods: edentulous patients (n = 16) received one set of new complete dentures and after the intraoral adjustments and adaptation period (30 days), the Brazilian version of Oral Health Impact Profile for assessing edentulous subjects (Ohip-Edent) was used to evaluate the oral health-related quality of life (OHQOL) of the participants. Additionally, the kinesiograph instrument K6-I (Myotronics Research Inc., Seattle, WA) was used to record opening and closure range of movement, mandibular movement, and the pattern of maxillary complete denture movement on chewing. Afterwards, the patients had their mandibular complete dentures replaced by a complete fixed denture and the same evaluation protocol was performed after 3 and 6 months. Ohip-Edent responses were analyzed using Wilcoxon's test for repeated measures (α = .05) and Kinesiographic data using the Student´s t test (α = .05). Results: The Ohip-Edent showed an improvement of general oral health-related quality of life after 3 and 6 months of the treatment with complete fixed dentures. Kinesiographic recordings revealed a significant increase on maximum mandibular movements of vertical opening and no differences for the movement of the maxillary complete denture on chewing after treatment with complete fixed dentures was observed. Conclusion: the installation of complete fixed dentures improved the OHQOL and changed mandibular movements, with increases in vertical amplitude of maximal opening.

Impacto do uso de fita adesiva na qualidade de vida de pacientes institucionalizados e usuários de próteses totais convencionais

Objective: Evaluate the impact of the use of strip adhesive over the quality of life of institutionalized patients and wearers of complete dentures. Material and method: Twenty-nine institutionalized patients wearers of complete denture were selected to this study and after a clinical exam, a questionnaire (adjusted and based upon the index of Oral Health Impact Profile and Oral Health-Related Quality of Life, OHIP and OHQOL) was applied to evaluate issues related to epidemiological conditions (gender and age), quality of life (pain, discomfort, functional limitations, phonetic, social, psychological and esthetic), taste and notion of implant treatment. Following this part, the patients received instruction to use the strips adhesives (Corega Fita Adesiva, Glaxo-Smith-Kline, Rio de Janeiro, Brazil), considering three in maxillary prosthesis and two in the lower prosthesis during a period of 30 days. After this period, all the patients were recall and the questionnaire was reapplied; add some adhesive performance questions, to compare the results before and after the adhesive use in terms of percentage. Result: After the adhesive strips use there were improvement of the functional, social and physcological limitation aspects, but without percentual increasement of phonetic and esthetics aspects. The results showed 65.5% of the answers stating adhesive maintenance between 6-12 hours, easy removal (68.9%), and without change the taste (89.6%). The notion for implant treatment was decreased changing from 75.8 to 37.9% after the adhesive use. Conclusion: The results enhanced a positive impact over quality of life of the respondents after the strip adhesive use, showing decrease of pain and discomfort, mainly of inferior dental prosthesis.

Análise das proporções faciais e sua relação com o formato dentário e com a dimensão vertical de repouso e de oclusão entre discentes institucionalizados

Considering the importance of the esthetic and the adequate register of vertical dimension (VD) to the oral rehabilitation, this study had as aims the analysis and comparison of two methods to get VD (Pleasure and Willis), functional space (FE), acquisition and correlation of facial and dental measurements. To do this, rest (RVD) and occlusal vertical dimension (OVD) and FE were achieved from the 30 students of the Federal University of Goias College of Dentistry. Following that, dental measurements of height and of the superior central incisors (SCI) and canine distance were registered. A facial analysis was performed to get the intercomissura, interalar, interpupilar, intercantal distance, besides register parameters as coincidence of dental and facial line, type of smile, face and SCI forms, and mastication type. The collected data were tabulated, compared by medias and standard deviations, and submitted to non-parametrical statistical analysis of Kruskal-Wallis and .Mann-Whitney with 5% of probability. The results doesn’t indicated statistical significant difference between FE of the two techniques. The measures of facial analysis are comparable with literature published data’s, but can’t be used as a parameter to the selection of intercanine distance. In 56.7% of the cases, there were coincidences of face and SCI forms, which could be a viable parameter in the selection of acrylic resin artificial tooth.

O Uso do Arco Facial para o correto posicionamento dos modelos no articulador

It presented the main features so that the wax plan can be conveniently filling the aesthetic and functional requirement of a denture. The steps of face bow mounting and wax plan transfer form the mouth to the articulator, considering the necessary requirement for this purpose are shown. This sequence aims to instruct and warn those who work with dentures about the needs of using face bows for correct reproduction of the models positioning in the articulator

Como realizar o selamento periférico e a moldagem funcional?

The functional impression technique is one of the most important steps for complete and/or partial edentulism treatment. So, correct analysis and record of supporting structures are essential to determine the denture extension. The functional impression technique has two stages - a customized final impression tray and a border impression - which aims to record the optimal denture supporting area. The aim of this study was to review the literature related to border impression and functional impression techniques, describing the technique and materials, and identifying the procedure’s objectives and function.

Técnicas de obtenção da posição de relação central em pacientes edêntulos

Edentulism causes loss of horizontal intermaxillary relationship, which is defined by the condyle position in the joint cavities, called centric relation. The correct record of centric relation in edentulous pacients has a strong influence on the treatment final result and is considered one of the most difficult clinical steps to achieve success. The aim of this study was to describe the main centric relation recording methods for edentulous patients reported in the literature. The study described physiological methods such as swallowing and pull tongue back, manipulative and graphic methods. It is concluded that the combination of different methods facilitates the correct centric relation record. Dentists must have a good knowledge of those techniques to perform this procedure satisfactorily.

Prova estética e funcional: uma decisão em conjunto

An important phase of rehabilitation treatment, is the aesthetic and functional testing, performed with the patient. Its relevance is because at this time it’s possible to have a very faithful preview of the final result of the prosthesis, but, if necessary, still allow changes. Therefore, the objective of this review is to describe didactically the clinical steps and factors that should be examined by the dentist at the moment of aesthetic and functional testing of a complete denture. This clinical stage basically involves four requirements to be analyzed: mechanical, functional, aesthetic and phonetic. After the jointly analysis with all the requirements, the patient must approve, preferably in writing, the completion of the prosthesis. In case of need for any changes, this is when it should be performed, followed by new aesthetic and functional testing. It should be noted that the patient’s opinion is always sovereign in deciding to end the denture.

Uso de sistema de retenção magnético como opção de tratamento para solução de caso com espaço interoclusal reduzido
