Food Bolus Properties in Relation to Dentate and Prosthetic Status

Abstract

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.

The Biomechanical Impact of Loss of an Implant in the Treatment with Mandibular Overdentures on Four Nonsplinted Mini Dental Implants: A Finite Element Analysis

“…MDIs have certain advantages compared to conventional implants: studies have demonstrated the occurrence of lower stresses, the smaller diameter and the resilience offered by the attachment system, which allow the comparison of MDIs behavior to a stress breaker [ 29 ]. Moreover, the presence of conventional implants or MDIs improves the stability of the denture and, implicitly, functional efficiency in the preparation of the food bowl [ 32 ]. The denture design must cover the entire support area of the prosthetic field, and meet all the clinical and technical conditions for the realization of such a prosthodontic restoration; one of the most important parameters to consider is the type of connection with the implant, occlusal scheme and marginal adaptation [ 31 ].…”

“…The finite element partitioning was a compromise between the accuracy of the discretization and the computational possibilities. The loading was the pressure on the surface of these cylinders, so that the total equivalent force was 150 N [ 23 , 27 , 29 ]. To simulate some clinical aspects, the application of pressure was carried out as follows: on the incisal surfaces of the frontal teeth, a clinical situation specific to the action of cutting food; bilaterally, on the occlusal surfaces of the lateral teeth, a situation that corresponded to the maximum intercuspation position and deglutition; unilaterally, on the occlusal surfaces of the lateral teeth, a situation that corresponded to unilateral chewing action.…”

“…Prosthodontic manufacturing technology is also important, and the use of modern injection under the pressure techniques of thermo-polymerizable resins can ensure that more reliable dentures are obtained, in terms of bending resistance, decreasing the risk of the denture bases fracturing [ 22 ]. In situations where the overdentures’ support becomes deficient, due to the involution of bony, mucous, or muscular structures of the dento-maxillary apparatus, areas of acrylic base overload may appear near certain implants or MDIs, with an increased risk of fracture, considering that the support differs depending on the chosen implant system [ 23 ]. Through the loss of one or more implants, biomechanical changes may occur in the behavior of the overdentures, increasing the risk of complications.…”

Psychometric Assessment of the Romanian Version of the Index of Dental Anxiety and Fear (IDAF-4C+)

“…Therefore, it is suggested that people with a high level of dental anxiety are at risk to become wearers of removable prostheses. This alternative is not always the most indicated when compared with other variants, in regard to several aspects such as oral health-related quality of life or masticatory performance [23][24][25]. In this study, participants who had removable denture treatment had a higher chance of responding affirmatively to "fear of going to the dentist significantly affects my life in some way (dental pain, avoiding eating some foods, embarrassed or self-conscious about appearance of teeth or mouth, etc.)".…”
