“…Various parameters have been used to identify functional deficits in individuals with dentofacial deformities, the most commonly studied being bite force , muscular activity and masticatory efficiency . Studies have shown that the masticatory muscle strength is lower in individuals with dentofacial deformities than in individuals without them .…”

The objective of this study was to determine whether dentofacial deformities (class II and class III) influence maximum isometric tongue strength compared with a group without deformities. A total of 126 adult patients participated in the study. Of these, 45 had a class II diagnosis (14 men and 31 women) and 81 a class III diagnosis (35 men and 46 women), all of them with indication of orthognathic surgery. Fifty adult volunteers (17 men and 33 women) with no changes in dental occlusion (class I) and with no clinical signs of dysfunction of the temporomandibular joint represented the control group. Tongue strength (in N) was measured with a dynamometer. The maximum strength of the anterior portion was determined with the instrument positioned on the retroincisor region and the maximum strength of the dorsum with the instrument positioned in the region of the hard palate. Data were analysed statistically by analysis of variance (anova) and by the Pearson correlation test. No significant difference (P > 0·05) in tongue strength in the anterior or dorsal region was observed between the groups with dentofacial deformities or between these groups and the control. The tongue strength of the anterior and dorsal regions was not influenced by the dentofacial deformity.

“…Children with distal occlusion, aged 6 -15, have masticatory efficiency reduced to 15 -20%; those with medial occlusion, respectively to 15 -30%; children with occluded front -16 -66 %; and those with deep occlusion -24 -54%. Picinato-Pirola et al (15) have established a statistically significant difference in masticatory efficiency for patients with class I, class II and III dentofacial deformities. There is no statistically significant difference between the two groups with sagittal skeletal deformities, which is a proof that the change in position of the lower jaw is associated with altered occlusal relationships as well as masticatory muscles tone.…”

The impaired balance in articulation and occlusion can be due to anatomical or iatrogenic causes, nevertheless, it always violates the coordination of morphological structures of the masticatory apparatus and their function. The authors of the present paper aim to explore all available literature in an attempt to analyze mastication and speech functions in patients with unbalanced occlusion and articulation, the result of dentofacial deformities and/or missing teeth and inadequate prosthetic treatment.

“…Subjects with dento-facial deformities and orthodontic needs may present a deficient masticatory function (Tate et al, 1994;van den Braber et al, 2001;English et al, 2002;Iwase et al, 2006;N'Gom et al, 2007;Magãlhaes et al, 2010;Picinato-Pirola et al, 2012;Abrahamsson et al, 2013;Hennequin et al, 2015). These subjects often display an interarch discrepancy or inadequacy, as reflected by the significantly reduced functional area (Kobayashi et al, 1993;Henrikson et al, 1998;Magãlhaes et al, 2010;Bourdiol et al, 2017).…”

This review deals with the frequent wide variability of masticatory capacity/incapacity. Neither researchers nor clinicians have taken sufficient account of this variability despite its implications for nutrition. Mastication in normal healthy oral conditions is first described, followed by a short presentation of the mechanisms of masticatory adaptation in the nervous system. Capacity, incapacity, and successful compensatory adaptation of mastication are then defined, along with the different methods used for their evaluation. Examples of adaptation needs are given, such as those concomitant with dental wear or occlusal changes. Finally, given its vital importance for deeply impaired mastication/deglutition function, the impact of masticatory adaptation processes on nutrition is examined.
