“…The lack of peripheral feedback mechanisms in patients with implant-supported full fixed prostheses may lead to a lack of control over the biting force [3, 29]. Such control is needed for refinement and control of the biting force for various types of food [7, 30–32]. While patients with implant-supported bridges are able to bite food with varying levels of hardness, it could be questioned whether they are able to differentiate between the hardness variations and thus apply an adapted chewing pattern [33].…”

“…Although adaptation to food texture during mastication by dentate subjects has been tested [34], it has not yet been followed up in patients receiving implant placement. In a recent cross-sectional study, mastication adaptability in patients with implant-supported bridges was assessed with soft and hard food models using an electromyogram (EMG) [7]. Patients with implants showed a significantly weaker increase in EMG activity with increased food hardness.…”

Short-term follow-up of masticatory adaptation after rehabilitation with an immediately loaded implant-supported prosthesis: a pilot assessment

BackgroundWhen teeth are extracted, sensory function is decreased by a loss of periodontal ligament receptions. When replacing teeth by oral implants, one hopes to restore the sensory feedback pathway as such to allow for physiological implant integration and optimized oral function with implant-supported prostheses. What remains to be investigated is how to adapt to different oral rehabilitations.The purpose of this pilot study was to assess four aspects of masticatory adaptation after rehabilitation with an immediately loaded implant-supported prosthesis and to observe how each aspect will recover respectively.MethodsEight participants with complete dentures were enrolled. They received an implant-supported acrylic resin provisional bridge, 1 day after implant surgery. Masticatory adaptation was examined by assessing occlusal contact, approximate maximum bite force, masticatory efficiency of gum-like specimens, and food hardness perception.ResultsOcclusal contact and approximate maximum bite force were significantly increased 3 months after implant rehabilitation, with the bite force gradually building up to a 72% increase compared to baseline. Masticatory efficiency increased by 46% immediately after surgery, stabilizing at around 40% 3 months after implant rehabilitation. Hardness perception also improved, with a reduction of the error rate by 16% over time.ConclusionsThis assessment demonstrated masticatory adaptation immediately after implant rehabilitation with improvements noted up to 3 months after surgery and rehabilitation. It was also observed that, despite gradually improved bite force in all patients, masticatory efficiency and food hardness perception did not necessarily follow this tendency. The findings in this pilot may also be used to assess adaptation of oral function after implant rehabilitation by studying the combined outcome of four tests (occlusal contact, maximum bite force, masticatory efficiency, and food hardness perception).

“…The adaptation of chewing behavior to food hardness can also characterize healthy mastication. Adaptation to increasing food hardness results in an augmented number of chewing cycles and an increase in the chewing sequence duration, with no modification of the chewing frequency (number of cycles per second) in healthy subjects 3,7,13 . The mean chewing frequency is slowed down in subjects with chewing deficiencies while eating any type of resistant food.…”

Impact of removable partial denture prosthesis on chewing efficiency

Removable partial denture prostheses are still being used for anatomic, medical and economic reasons. However, the impact on chewing parameters is poorly described.ObjectivesThe objective of this study was to estimate the impact of removable partial denture prosthesis on masticatory parameters.Material and MethodsNineteen removable partial denture prosthesis (RPDP) wearers participated in the study. Among them, 10 subjects were Kennedy Class III partially edentulous and 9 with posterior edentulism (Class I). All presented a complete and full dentate opposing arch. The subjects chewed samples of carrots and peanuts with and without their prosthesis. The granulometry of the expectorated boluses from carrot and peanuts was characterized by median particle size (D50), determined at the natural point of swallowing. Number of chewing cycles (CC), chewing time (CT) and chewing frequency (CF=CC/CT) were video recorded.ResultsWith RPDP, the mean D50 values for carrot and peanuts were lower [Repeated Model Procedures (RMP), F=15, p<0.001] regardless of the type of Kennedy Class. For each food, mean CC, CT and CF values recorded decreased (RMP, F=18, F=9, and F=20 respectively, p<0.01). With or without RPD, the boluses' granulometry values were above the masticatory normative index (MNI) determined as 4,000 µm.ConclusionRPDP rehabilitation improves the ability to reduce the bolus particle size, but does not reestablish fully the masticatory function.Clinical relevanceThis study encourages the clinical improvement of oral rehabilitation procedure.

“…That was shown during mastication of edible viscoelastic model foods. Adaptation to increasing food hardness results in an increased number of chewing cycles and an increase in the chewing sequence duration, with no modification of the chewing frequency (number of cycles per second) in healthy subjects [Lassauzay et al, 2000;Peyron et al, 2002;Grigoriadis et al, 2011]. The mean chewing frequency is slowed down in subjects with chewing deficiencies while eating any type of resistant food.…”

Chewing Deficiencies in Adults with Multiple Untreated Carious Lesions

2013

View full text Add to dashboard Cite

Persons who have multiple untreated carious lesions are at high risk of chewing difficulties and consequently an unhealthy diet, but few data are available on the impact of untreated caries on mastication in adults. This study in adults with multiple untreated caries lesions aimed to evaluate chewing deficiencies using physiological and psychosocial indicators. Forty-five patients, mean (±SD) decayed teeth 11.5 (±5.2), and 20 fully dentate caries-free subjects were observed during mastication of raw carrot and two jelly model foods differing in hardness. Criteria for chewing evaluation were carrot bolus granulometry, food refusals, chewing activity (chewing time, number of chewing cycles, chewing frequency) and oral health-related quality of life (GOHAI). Dental status was characterized by caries experience (DMFT) and posterior functional pairs of teeth. Adults with multiple untreated caries lesions suffered from chewing deficiencies, demonstrated by a decrease in food comminution related to the number of posterior functional teeth, food selection and functional alterations in oral health-related quality of life. The ability to adapt chewing activity to food hardness was preserved in this group. Further studies should be conducted to determine whether chewing function could be improved after dental treatment.

Adaptability of mastication in people with implant-supported bridges

Abstract: People with implant-supported bridges show an impaired adaptation of the muscle activity to food hardness during mastication. We suggest that a lack of sensory signals from periodontal mechanoreceptors accounts for the impairment.
