Fuerza máxima de mordida en pacientes adultos mayores de origen mapuche y no mapuche portadores de prótesis parciales removibles clase I Kennedy / Maximum bite force in elderly Mapuche and non-Mapuche patients with Kennedy class I removable partial dentures

OBJETIVO Comparar la fuerza máxima de mordida (FMM) de los pacientes adultos mayores portadores de prótesis parciales removibles con extremo libre bilateral (clase I Kennedy) maxilar y mandibular, en individuos mapuches y no mapuches durante 2 períodos diferentes de medición. PACIENTES Y MÉTODOS Se dividió a 40 sujetos cuyas edades fluctuaban entre 60 y 80 años en 2 grupos de acuerdo con su origen étnico para medir su FMM en la región de molares a través de un dispositivo hidráulico. Los sujetos fueron instruidos para realizar 3 mordidas por lado lo más fuerte posible y el valor más alto fue considerado como fuerza máxima. Los datos fueron analizados por medio del test t de Student y prueba de Levene. RESULTADOS El género masculino presentó mayores valores de FMM (p < 0,05). Además, el grupo de individuos de etnia mapuche presentó mayores valores de FMM (p < 0,05). Se identificaron valores de FMM considerablemente mayores en el período de un mes posterior a la inserción de la nueva prótesis (p < 0,05). CONCLUSIONESLos mayores valores de FMM fueron observados en la etnia mapuche, en individuos de género masculino y un mes posterior a la inserción de ambas prótesis.

OBJECTIVE To compare the maximum bite force (FMM), in two different measurement periods, of mapuche and non-mapuche elderly patients with both maxillary and mandibular Kennedy class I removable partial dentures. PATIENTS AND METHODS A total of 40 subjects with ages ranging between 60 and 80 years were divided into 2 groups according to their ethnic origins to measure FMM in the molar region using a hydraulic device. The subjects were instructed to perform three bites with each side as hard as possible, and the highest value was considered as the maximum force. Data were analyzed by Student's t- test and Levene test. RESULTS Male gender showed higher FMM values (p < 0.05). The group of mapuche individuals showed the highest values of FMM (p < 0.05). Finally, considerably higher FMM values were identified at one-month period subsequent to the insertion of the new prosthesis (p < 0.05). CONCLUSIONS The highest FMM values were observed in patients of mapuche ethnic origin, in male patients, and at one-month period after both prostheses were inserted.

Maximum bite force in elderly indigenous and non-indigenous denture wearers.

The aim of this study was to compare the measures of maximum bite force (MBF) in elderly edentulous indigenous (Mapuche) and non-indigenous individuals with new complete dentures at two different measuring times. A sample of 100 elderly subjects was divided into two groups: 50 indigenous and 50 non-indigenous, each including 25 females and 25 males. All individuals were totally edentulous, with new maxillary and mandibular removable complete dentures. Measurements were taken at the time of new prosthesis placement and after 1 month of use. Subjects were asked to perform with maximum effort three bites per side at maximum intercuspidation, with a rest time of 2 minutes in between. Statistics were analyzed with Student 's t-test. The MBF values were significantly higher in indigenous than non-indigenous subjects. Force after 1 month of wearing the new prosthesis was significantly higher than at the time of new prosthesis placement. No significant difference was found between sides. Elderly indigenous complete denture wearers had the greatest MBF values. Denture wearers were observed to undergo an adaptation process to the new prosthesis, with MBF increasing considerably after one month of use.

Subjects were asked to perform with maximum effort three bites per side at maximum intercuspidation, with a rest time of 2 minutes in between. Statistics were analyzed with Student s t-test. The MBF values were significantly higher in indigenous than non-indigenous subjects. Force after 1 month of wearing the new prosthesis was significantly higher than at the time of new prosthesis placement. No significant difference was found between sides. Elderly indigenous complete denture wearers had the greatest MBF values.

Maximum bite force idn elderly indigenous and non-indigenous denture wearers

El objetivo de este estudio fue comparar las medidas de fuerza máxima de mordida (MBF) en pacientes desdentados adultos mayores indígenas (Mapuches) y no indígenas, en el momento de recibir sus prótesis totales y un mes posterior a la inserción.Una muestra de 100 sujetos adultos mayores fue dividida en dos grupos: 50 indígenas y 50 no indígenas, cada uno de ellos con 25 pacientes de sexo femenino y 25 masculino. Todos los individuos estudiados eran completamente edéntulos, quienesrecibieron prótesis removibles totales nuevas tanto superior como inferior. Las medidas fueron realizadas en el momento de la inserción de ambas prótesis y posterior a un mes de uso. Seles solicitó a los sujetos que realizaran un esfuerzo máximo con tres mordidas por lado en máxima intercuspidación, con un tiempo de descanso de 2 minutos entre cada medición. El análisisestadístico fue realizado por medio del test t-Student´s. Los valores de fuerza máxima observados en los sujetos indígenas fueron significativamente mayores que en los individuos no indígenas. Además, los valores de fuerza posterior al mes de uso dela prótesis nueva fueron significativamente mas altos que losobtenidos al momento de la inserción de la prótesis. Por otro lado, no se identificaron diferencias significativas en los valores entre los lados izquierdo y derecho. Así, los pacientes indígenasmostraron valores mayores de fuerza masticatoria máxima. También, se pudo observar que los pacientes sufrieron un proceso de adaptación a las prótesis nuevas, en los cuales la fuerza máximamasticatoria posterior a un mes aumentó considerablemente...
