“…Thus, after implant treatment, subjects needed only about half the number of chewing cycles as before treatment to comminute their food to half the initial size. Jaw muscle activity during chewing did not significantly change after implant treatment (193, 194). A decrease in masseter muscle activity during swallowing was observed after implant treatment, which may indicate adaptation to the new condition of more stability of the mandibular denture (194).…”

The long‐term effects of implant treatment on oral function also proved to be promising (80, 185, 195–197).…”

During chewing, food is reduced in size, while saliva moistens the food and binds the masticated food into a bolus that can be easily swallowed. Characteristics of the oral system, like number of teeth, bite force and salivary flow, will influence the masticatory process. Masticatory function of healthy persons has been studied extensively the last decades. These results were used as a comparison for outcomes of various patient groups. In this review, findings from literature on masticatory function for both healthy persons and patient groups are presented. Masticatory function of patients with compromised dentition appeared to be significantly reduced when compared with the function of healthy controls. The influence of oral rehabilitation, e.g. dental restorations, implant treatment and temporomandibular disorder treatment, on masticatory function will be discussed. For instance, implant treatment was shown to have a significant positive effect on both bite force and masticatory performance. Also, patient satisfaction with an implant-retained prosthesis was high in comparison with the situation before implant treatment. The article also reviews the neuromuscular control of chewing. The jaw muscle activity needed to break solid food is largely reflexly induced. Immediate muscle response is necessary to maintain a constant chewing rhythm under varying food resistance conditions. Finally, the influence of food characteristics on the masticatory process is discussed. Dry and hard products require more chewing cycles before swallowing than moist and soft foods. More time is needed to break the food and to add enough saliva to form a cohesive bolus suitable for swallowing.

“…To some extent, these results are surprising and should be thought over. Authors as Greska 11 (1995) and Papas et al 16 (1998) evaluated the impact of oral rehabilitation the neuromuscular coordination involved in the masticatory process 24 , influencing the dietary intake.…”

“…The improvement of dentures benefits the masticatory ability with positive impact on the nutritional status 21 , increasing body weight and albumin level 22 without changes on intake of energy and nutrients 23 . Moreover, the treatment with implanted-supported dentures can modify the function of stomatognathic system 24 and the nutritional status of edentulous elderly individuals, thus enhancing their anthropometric 25 and biochemical evaluation 26 .…”

Purpose: the aim of this study was to evaluate the nutritional status of elderly individuals submitted to surgical-prosthetic oral rehabilitation procedures. Methods: fifteen patients completely edentulous aged 60 years or more were assessed (10 women and 5 men). All individuals wore removable dentures in both arches and had their mandibular dentures replaced by implant-supported prostheses, were submitted to nutritional evaluation comprising anthropometric aspects, biochemical blood analysis and dietary evaluation before surgery and at three and six months after surgery.Results: statistical analysis of the anthropometric evaluation did not reveal significant difference between the study periods, for all parameters investigated. The biochemical evaluation revealed a significant increase in albumin three months after dental treatment, returning to lower levels after six months. The dietary evaluation evidenced that the caloric intake, macronutrients proteins and carbohydrates was not altered after dental treatment. Conversely, the ingestion o lipids were lower six months after dental treatment compared to the previous results. Conclusion: therefore, the placement of implant-supported complete dentures in the elderly individuals investigated in this study did not modify the nutritional condition in the short term, suggests that the subjects maintained the previous dietary characteristics. PatientsFifteen elderly individuals were selected, by non-probability convenience sampling, being ten women and five men, aged 60 to 76 years, with median of 64 years, who attended the Maxillofacial Surgery and Traumatology, Prosthodontics and Implantology Clinics of the Dental School at the aforementioned university. How inclusion criterion all individuals had good general health, were edentulous, wore complete removable dentures, and presented good clinical conditions of the maxillary arch and mandibular bone structure that allowed placement of implants with minimum length of 10mm.Individuals with history of neurological diseases, head and neck tumors, psychological and psychiatric disorders were excluded, as well as smokers, alcoholics and individuals with abnormal maxillomandibular relationship, such as mandibular prognathism or retrognathism.The individuals were evaluated at three different periods: before (Pre), three months (Post1), and six months (Post2) after the surgical-prosthetic procedure. Surgical-prosthetic proceduresBefore surgery, the conditions of maxillary and mandibular complete dentures worn by the patients were evaluated. Dentures considered as inadequate were replaced.The patients were submitted to the surgical protocol suggested by Branemark et al. 31 (1977), comprising placement of five endosseous implants with 4, 4.5 or 5-mm diameter with smooth surface in the mandibular arch. After implant placement, the abutments were fixed to the implants, followed by procedures for preparation, finishing, polishing and fitting of dentures. The time interval between the insertion of implants and placement of...

RESUMOObjetivo: Avaliar as funções do sistema estomatognático em idosos usuários de prótese dentária. Material e Métodos: Realizou-se avaliação fonoaudiológica constituída por uma anamnese e uma avaliação clínica composta por duas etapas. Na primeira etapa, foram observadas as características corporais e faciais gerais. Na segunda etapa, realizouse avaliação das estruturas orofaciais e das funções orais por meio da observação e apalpação. Foram incluídos indivíduos com mais de 60 anos, usuários de prótese dentária parcial superior e/ou inferior e total superior e/ou inferior. Resultados: Avaliou-se 44 idosos que foram divididos em três Grupos, de acordo com o tipo de prótese: Grupo 1 idosos sem falhas dentárias com 18 idosos; Grupo 2 composto por usuários de prótese total superior e inferior, com 14 idosos; Grupo 3 constituído por usuários de prótese parcial removível superior e inferior com 12 idosos. Destes 84,9% do sexo feminino. Com relação à função de deglutição observou-se presença de alteração em 55,5% dos idosos no Grupo 1, 85,7% no Grupo 2 e 91,6% no Grupo 3, desta forma os usuários de prótese dentária apresentaram valores maiores em comparação ao Grupo controle. Na função mastigatória, encontrouse alterações em 57,1% indivíduos do Grupo 2, e em 66,6% do Grupo 1 e 3. Conclusão: Desta forma, conclui-se que a utilização da prótese dentária ocasiona alterações nas funções do sistema estomatognático, mastigação e deglutição. Além disso, o tipo de prótese dentária utilizada pelo indivíduo ocasiona diferentes alterações com relação às estruturas. DESCRITORESFonoaudiologia. Prótese Dentária. Mastigação. Deglutição ABSTRACT Objective: To evaluate the stomatognathic system functions in aged denture wearers. Material and Methods: A phonoaudiological assessment was carried out consisting of anamnesis and a two-step clinical examination. Firstly, general facial and body features were observed. Secondly, orofacial structures and oral functions were checked through observation and palpation. The sample was composed of individuals aged more than 60 years, wearing upper or lower partial/ complete dentures. Results: A total of 44 elderlies were examined, who were divided into three groups according to the type of denture: group 1 including elderlies with no dental issues (n=18); group 2 consisting of elderlies wearing upper and lower complete dentures (n=14); and group 3 including elderlies with upper and lower partial dentures (n=12). Of these, 84.9% were female. Modifications of the swallowing function were observed in 55.5% of the subjects in group 1, 85.7% in group 2, and 91.6% in group 3, hence showing that denture wearers had higher prevalence of alterations in this function as compared to those in the control group. As to the chewing function, we found changes in 57.1% of subjects in group 2, and 66.6% in groups 1 and 3. Conclusion: The use of dentures leads to modifications in the functions of the stomatognathic system concerning chewing and swallowing. Furthermore, the type of denture used by the individual may...
