“…The research of Sharma et al [ 25 ] offered evidence that the replacement of mandibular conventional denture with an implant-supported mandibular overdenture considerably reduces mean particle size. Disagreeing with the previous study, but in accordance with this study’s results, the randomized controlled trial reported by Fontijn-Tekamp et al [ 26 ] found that there is no difference between patients with complete dentures and implant overdentures regarding food comminution, and the study of Van Doorne et al [ 8 ] showed that objective masticatory performance is similar in wearers of complete denture and mini dental implant overdentures. The lack of improvement of food fragmentation in mandibular implant overdentures compared to conventional dentures might be related to retention and stability problems, known as factors that impair mastication in bimaxillary complete denture wearers [ 27 ].…”

“…State-of-the-art research into masticatory performance highlights the importance of both subjective and objective methods of evaluation, as it is able to produce complementary data, frequently showing a weak association [ 6 , 7 ]. Moreover, objective assessments are considerably fewer than subjective ones, posing greater methodological challenges and difficulties [ 8 ]. Considering the importance of the objective knowledge of medical phenomena in general, masticatory performance included, we have chosen a method of assessment based on sieving the comminuted food, which is one of the most used in this regard [ 7 ].…”

“…Moreover, considering that oral, systemic and general factors may act as confounders, multiple studies are recommended in order to draw a conclusion with an adequate degree of certainty on the masticatory performance associated with different types of prosthetic rehabilitation. To our knowledge, a comparison between the specific prostheses analyzed in this research has not been made [ 8 , 9 , 10 ], and overall, more research is required on this topic, which is very important from a clinical perspective.…”

The objective of this study is to evaluate food bolus properties (mass, moisture content and food comminution) in patients wearing fixed or removable dental prostheses. Methods: A cross-sectional study was conducted on a convenience sample of patients aged at least 55 years old. Patients chewed a 10 g sample of fresh raw carrot until they felt ready to swallow. The mass of the food bolus was determined as collected and after drying. Food comminution was assessed by the multiple sieve method. Results: Patients with fixed prostheses compared to those with removable prostheses registered a similar mass of food bolus as collected (4.40 g vs. 4.60 g; p = 0.856); a higher mass of dried food bolus (3.46 g vs. 0.86 g; p < 0.001); lower moister of food bolus (24.65% vs. 82.35%; p < 0.001); and better food comminution (mass of smaller particles, of size below 2 mm, represented 65.93% vs. 20% of dried food bolus). In removable denture wearers, food comminution was slightly better in partially than in completely edentulous patients, and rather similar in completely edentulous patients with either implant overdenture or complete denture in the mandible, and complete denture in the maxilla. Conclusions: The current results suggest that food bolus properties are dependent on the dentate and prosthetic status.

Patients with atrophic maxilla are a challenge, since this condition can compromise the installation of implants. Hybrid implants system made by CAD/CAM, installed in the zygomatic and canine pillars bilaterally. The AL system consists of mini plates connected in a prosthetic abutment that is screwed into an implant-supported complete denture. There was performed a biomechanical evaluation of the AL system under mastication load simulation. A model of a patient's bone was built using In Vesalius software, exported, and treated in a CAD system. The AL implants and the prosthesis fixation bar were modeled based on the Bio model’s geometry. A structural static simulation of the bar was carried out and the supportive reactions were applied on the implants. The simulation was performed for a critical chewing load of 756 N. In this case, the maximum von Mises tension in the fixation bar and the minimum safety factor were respectively 366 MPa and 1.91. In a simulation of a 5 times lower load total edentulous chewing load, the safety factor was 9.55 and 17.10 for the fixation bar and the implants. The fixation bar and implants have the capacity to withstand the stresses to which they will be subjected during chewing.

“…8,9 The MP index can be assessed using standardised tests which analyse the ability to grind or mix food. 10,11 A suitable method for edentulous subjects is the mixing-ability test based on colorimetric technique measurement. 7 The degree of mixing of a two-colour material (usually a two-colour chewing gum) is evaluated visually on a reference scale or optoelectronically.…”

ObjectiveThis prospective study is part of a randomised clinical trial and reports the changes in masticatory performance (MP) and bite force, and explores their influential factors, 1 year after the provision of mandibular overdentures retained by four titanium–zirconium mini implants.MethodsEdentulous patients received conventional complete dentures, followed by placement of four mini implants (Straumann® Mini Implant System) in the anterior mandible and converting the conventional prosthesis into a mandibular overdenture. Treatment protocols were randomised using a 2×2 factorial design combining different surgical (flapped vs. flapless) and loading (immediate vs. delayed) protocols. MP was assessed using a two‐colour mixing ability test and a colorimetric analysis to measure the level of colour mixing (Variance of Hue–VoH). Maximum voluntary bite force (MBF) was measured by a digital gnathodynamometer in the posterior and anterior regions. Sex, age, surgical and loading protocols and ridge morphology were tested as independent variables. MP and MBF tests were performed at baseline (pre‐treatment) and the 3‐, 6‐ and 12‐month after implant loading. Descriptive statistics, independent t‐test, and linear mixed‐effect model (LMM) regression were used for data analysis.ResultsSeventy‐four participants were assessed and 73 completed the 1‐year follow‐up. Statistically significant improvements in functional parameters were observed in all follow‐up periods compared to baseline (p < .001). The flapless protocol was associated with higher improvement in MP at the 3‐month follow‐up (p = .004), while less resorbed ridges were associated with better MP (p = .038) and higher MBF (p < .001).ConclusionThe mandibular overdenture protocol using four titanium–zirconium mini implants was effective in improving MP and MBF of edentulous patients, compared to pre‐treatment values. The findings also suggest that improvements in chewing function and bite force are impacted by clinical factors since better outcomes were observed for flapless surgeries and less resorbed edentulous ridges.CLINICAL TRIAL REGISTRATIONClinicalTrials.Gov ID NCT04760457.
