Perfil das condições sistêmicas e bucais de usuários de próteses removíveis atendidos em um Serviço de Medicina Bucal

A presença de doenças sistêmicas, uso de medicamentos, e uso de próteses removíveis, entre outros fatores, podem alterar o equilíbrio fisiológico da cavidade bucal favorecendo o estabelecimento de diversas alterações e/ou patologias bucais. Assim, o estudo das prevalências destes fatores, nos pacientes odontológicos, tornam-se importantes pois devem ser considerados para elaborar o diagnóstico e definir a conduta terapêutica. Com o objetivo de delinear um perfil, avaliamos os prontuários de 500 usuários de próteses removíveis atendidos no Serviço de Medicina Bucal da Faculdade de Odontologia de Araraquara - UNESP. Analisamos os dados referentes a: características da população e das próteses removíveis, prevalência das doenças sistêmicas, uso de medicamentos e diagnóstico final das patologias ou alterações bucais. Os resultados obtidos nos permitem concluir que a maioria (74%) dos usuários de próteses removíveis eram mulheres brancas; metade da população pertencia a faixa etária de 41 a 60 anos e, quase a metade (49,2%) usava a combinação de prótese total superior e inferior. As doenças sistêmicas foram relatadas por 57,2% da amostra e a prevalência maior foi de doenças do sistema cardiovascular (25,4%). A maioria (60,4%) da população relatou uso de medicamentos e, dentre os mais freqüentes, a prevalência maior foram dos cardiovasculares (26,4%). A prevalência de patologias ou alterações bucais foi de 99,6%, sendo as relacionadas ao uso de próteses removíveis as mais freqüentes. Dentre estas, a candidose crônica atrófica ocorreu em 81,8% da população estudada e a hiperplasia fibrosa em 29,2%.

Subjective assessment of adhesives usage by complete denture wearers in a brazilian population

The information about the knowledge and usage of denture adhesives is still limited, particularly in Brazilian populations. Objective: The purpose of this study was to investigate the aspects related to the use or nonuse of denture adhesives by complete denture wearers. Material and method: Questionnaires were applied to 100 bimaxillary complete denture wearers concerning their usage of denture adhesives. The survey was carried out according to three categories: those who had never tried adhesive, those who had tried adhesive at least once but no longer used it, and those who currently used it. Result: Of the 100 participants, 80% had never tried adhesives, 16% had tried at least once but no longer used it and 4% had used on a regular basis. Conclusion: Within the limitations of this study, the results of this subjective assessment suggest that within the participants that had never tried adhesives, 77.5% inform that the adhesive is not needed, and all participants who regularly use it inform its efficiency.

Reabilitação oral de paciente com síndrome da combinação: relato de caso

The Combination Syndrome represents an important pathologic condition of the masticatory system that requires a complex rehabilitation treatment. The presence of flaccid mucosa is one of the most common features due to bone resorption of the pre-maxilla caused by anterior hyperfunction of the mandibular teeth on the maxillary complete denture, where the impact of oclusal loading in this region results in movement of the maxillary prosthesis into the ridge, resulting in increased resorption of the residual ridge, internal misfit and loss of the retention of the maxillary complete denture. The presence of flaccid mucosa, in such cases, leads to problems of support and stability of the maxillary complete denture, which can be treated by surgical reduction of the thickness of the tissue or using specific techniques of fabrication of prostheses. This article describes the oral rehabilitation of a patient with the Combination Syndrome where the surgical reduction of flaccid mucosa was not performed, using a modified technique of functional impression in two steps, with the objective of generating forces and less distortion in flaccid mucosa during functional impression.

Hipertonicidade muscular e confecção de próteses totais pela técnica da zona neutra: relato de caso clínico

Introduction: the oral rehabilitation in edentulous patients using removable complete dentures is a classic treatment, easily accessible, and presenting satisfactory results. However, to succeed in this type of treatment, stability is an extremely important factor. The neutral zone technique for the production of complete dentures determines the oral cavity space for the positioning of teeth and denture base that provide a neutralization of the forces delivered by lips, cheeks, and tongue, providing better stability and retention of prostheses, which is indicated in cases with history of difficulties in adapting the conventional mandibular denture. Objective and case report: this paper aimed to describe a clinical case report of the oral rehabilitation of a patient with paraprosthetic muscles hypertonicity through removable complete dentures produced by the neutral zone technique, using condensation silicone. Final considerations: the use of condensation silicone for the development of the neutral zone technique showed to be a good alternative for the development of this clinical case, providing satisfactory stability and retention of the complete mandibular denture.

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.
