Extra short 4mm implants used to rehabilitation of atrophic posterior mandible. A serial case reports
2020
Rehabilitation of patients through implants in areas with severe bone resorption in the posterior mandible is a challenge in implant dentistry. In this context, extra short implants configure a treatment option for this type of patient, as they can avoid increased financial cost, treatment time and patient morbidity. The present study evaluated the marginal bone stability in individualized extra-short implants for masticatory function in the posterior mandible. Using digitized periapical radiographs of 13 extra-short implants performed on 7 patients. The mesial and distal regions of each implant were selected, from the bone crest to the region parallel to the apex, and the bone stability of…
Esthetic and functional oral makeover of a 3 year old cleft palate patient suffering from early childhood caries using unconventional techniques
2011
Cleft lip and palate (CL/P) are the most common congenital craniofacial anomalies. It has been observed that these children have a higher caries experience compared their non cleft counterparts. Early childhood caries results in early pulp involvement and gross destruction of the anterior and posterior teeth. This leads to decreased masticatory efficiency, difficulty in speech, compromised esthetics, development of abnormal tongue habits and subsequent malocclusion and psychological problems. The restoration of severely decayed deciduous teeth especially anteriors presents a special challenge to dentists, particularly in uncooperative children. The following case report documents the restor…
Investigating activity of masticatory muscles in patients with hypermobile temporomandibular joints by using EMG
2014
Background: Temporomandibular joint hypermobility (TMJH) can manifest higher range of motions in mandible. The aim of this study was to investigate and compare the activity of masticatory muscle of TMJs in healthy individuals and patients with mild, moderate and severe TMJH. Material and Methods: In this clinical study, 69 patients (between the ages of 22 to 42) with manifestation of TMJH were included. The patients were divided into three groups based on their maximum mouth opening (MMO): (light) with MMO of 50-55 mm; (moderate) with MMO between 55 to 65 mm; and (severe) with MMO >65 mm. Also, 20 healthy people with profiled tomography in the last 6 months were invited as control group (he…
Masticatory efficiency, bite force and electrical activity of the masseter and temporalis muscles in bodybuilders
2021
Made available in DSpace on 2022-04-29T08:32:43Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-09-01 Background: This study aimed to compare the masticatory efficiency, the maximum voluntary occlusal bite force (MVOBF) and the electrical activity (EMG) of masticatory muscles of practitioners of upper limb bodybuilding before and after physical activity. Methods: Twenty healthy individuals (10 men and 10 women, age from 18 to 30 (mean of 24.7 years old) without masticatory system disorders, that regularly practice hypertrophic physical activity were submitted to the analyses of masticatory efficiency, MVOBF, and surface EMG of the temporalis and masseter muscles. The masticatory effi…
Longitudinal effects of rapid maxillary expansion on masticatory muscles activity
2017
Background To investigate the modifications induced by rapid maxillary expansion (RME) on the electromyographic (EMG) activities of the anterior temporal and superficial masseter muscles, in patients without pre-treatment EMG alterations. Material and methods Twenty-one patients with unilateral posterior cross-bite selected from the orthodontic department of the University of L'Aquila (Italy), were enrolled. There was no control group in this study since each subject acted as a control of her/himself. Two surface EMG recordings were taken: T0 (before RME) and at T1 (3 month after the end of expansion). To verify the neuromuscular equilibrium, the EMG activities of both right and left masset…
B-mode versus A-mode ultrasonographic measurements of mucosal thickness in vivo
2002
Abstract Objective: The objective of this study was to compare the measurement accuracy of A-mode and B-mode ultrasonographic assessments of palatal masticatory mucosal thickness in vivo. Study Design: Thickness of palatal masticatory mucosa in the molar region of 50 volunteers was measured once with a B-mode ultrasound device (10 MHz) combined with a standoff for intraoral applications. At identical reading points thickness was also assessed with an A-mode device (5 replicates) and by needle probing for determination of true thickness. Results: On average true thickness ranged between 2.9 and 3.3 mm (95% confidence intervals; median, 3.1 mm). B-mode ultrasonography overestimated truth by 0…
Impact of Parkinson?s disease on the efficiency of masticatory cycles : electromyographic analysis
2019
Background This study evaluated the efficiency of masticatory cycles by means of the linear envelope of the electromyographic signal of the masseter and temporalis muscles in individuals with Parkinson’s disease. Material and Methods Twenty-four individuals were assigned into two groups: with Parkinson’s disease, average ± SD 66.1 ± 3.3 years (n = 12) and without the disease, average ± SD: 65.8 ± 3.0 years (n = 12). The MyoSystem-I P84 electromyograph was used to analyze the activity of masticatory cycles through the linear envelope integral in habitual mastication of peanuts and raisins and non-habitual mastication of Parafilm M®. Results There was statistically significant difference (P ≤…
Satisfaction in complete denture wearers with and without adhesives: A randomized, crossover, double-blind clinical trial
2018
Background The purpose of this study was to compare the satisfaction of patients regarding retention, stability and accumulation of particles with a randomized, double-blind crossed method in users with complete dentures with and without adhesive. Material and Methods Seventeen edentulous individuals were randomized and received new upper and lower complete dentures. After a period of adaptation, they participated in some masticatory tests and clinical revisions, after use the protheses with and without the use of two denture adhesives: Adhesive A (Fittydent, Fittydent International GmbH) and adhesive B (Corega, GlaxoSmithKline) at 0, 7 and 14 days. Satisfaction was measured immediately aft…
Immediate placement of single implant simultaneously with immediate loading in a fresh socket associated to periapical infection: a clinical case rep…
2015
Early restoration of the masticatory function, phonatory and aesthetics is some of the current goals of the therapy based on endosseous implants. Facing the classic protocols of implant insertion, which recommend a period of several months between extraction and implant placement, alternatives have been developed that demonstrate that immediate implant placement after tooth extraction permits adequate osseointegration, even in those cases where there is a periapical disease. The immediate restoration of implants after placement is a possibility where aesthetic requirements are high. This article presents a case with immediate implant placement and immediate loading of a first upper premolar…
The impact of oral rehabilitation with implants in nutrition and quality of life: A questionnaire-based survey on self-perception
2019
Background The association between tooth loss and masticatory problems may influence on food choices and consequently impact nutrition and quality of life. This study aimed to evaluate impact of oral rehabilitation with implants in nutrition and quality of life. Material and Methods A prospective study was performed. The Questionnaire for Healthy Habits (QHH) and the Oral Health Impact Profile-14 (OHIP-14) tools were used to assess nutrition and oral health status, respectively. Oral implants were placed and the adjacent the bone was radiographically assessed. The mean outcomes of the QHH between pre- and post-rehabilitation periods were assessed with the Wilcoxon Signed Rank test. The OHIP…
