“…As there are many obvious differences between male and female subjects, muscle volume correlated to electromyography (EMG) activity appear also to influence the amount of force exerted by masticatory elevator muscles. In the survey of smaller and moderate numbered cohort studies, bite force in edentulous patients both with and without dental implants seems to correlate well with masseter muscle thickness and measured EMG activity 52–57 . As EMG amplitude is considered a surrogate for occlusal force in some smaller case series, this factor increased for temporalis and masseter muscles in individuals where the number of chewing cycles were restricted 58 …”

Purpose: The purpose of this Best Evidence Consensus Statement was to search the literature to determine if there is a relationship between patient specific factors and occlusal force. Materials and Methods: A literature review was conducted in the following databases: Evidence-Based Medicine Reviews (EBMR), Cochrane Database of Systematic Reviews, Embase, and Ovid MEDLINE(R) and Epub Ahead of Print. Articles on patient factors and occlusal force were compiled by using a combination of the key words: "bite force," "occlusal force," "partial and complete edentulism," "bruxism," and "orthognathic class." Inclusion criteria included meta-analyses, systematic reviews, randomized controlled trials, case series, and journal articles. Exclusion criteria were case reports, studies in children, animals, and bench studies. Results: Of the 1502 articles that met the initial search criteria, 97 related to patientspecific factors affecting occlusal forces. These articles were evaluated, rated, and organized into appropriate categories addressing questions of foci. Conclusions: The range of occlusal force is highly variable among subjects correlated to patient specific factors such as age, gender, partial and complete edentulism, the presence of a maxillofacial defect, location of edentulous area, orthognathic profile, and magnitude of occlusal vertical dimension. Tooth replacement therapies targeted at increasing occlusal contact seem to have a positive effect on increasing occlusal force. Bruxism does not necessarily demonstrate higher occlusal powering but may have greater tooth contact time. Occlusal force is not clearly affected by the type of dental restoration or restorative material used. The clinical significance of the changes in occlusal forces is yet to be determined.

“…3 In this context, the mandibular single-implant overdenture (SIO), as opposed to a maxillary CD, has been investigated as an alternative to a set of conventional CDs. 1,4,5 Recent studies have shown that SIO improves masticatory performance (MP) and efficiency, 4,[6][7][8][9] maximum bite force (MBF), 6,10,11 muscle thickness, 11 and muscle activity 12 compared to the CD. Other studies revealed that the attachment type and load protocols for SIO could interfere with the prospective care of the SIO, mainly in terms of prosthetic maintenance events and implant survival rates, 5,7,13,14 requiring multiple clinical aftercare visits.…”

“…SIO fractures can be explained by the high concentration of compressive stress near the implant and attachment area, 16 resulting from the relining in the inner part of the CD made to house the matrix. 5,13,14,17 To delay or even prevent SIO fracture, some authors have suggested the inclusion of a framework in the anterior region of the overdenture 11,18,19 to dissipate mechanical forces better and reinforce the denture base. 8 Manufacturing a cobalt-chromium (Co-Cr) framework to strengthen the SIO can be considered an efficient and cheap procedure.…”

Introduction: To prevent single-implant overdenture (SIO) fracture, the inclusion of a framework in the overdenture has been suggested. However, no investigations verified their benefits.Objective: To evaluate prosthetic maintenance events, patient satisfaction, and mastication of SIO reinforced by metallic framework users.Material and methods: Fifteen volunteers had a new set of complete dentures converted into an SIO containing a framework. Maintenance events were recorded, while patient satisfaction was assessed using a visual analog scale. Masticatory performance (MP) was evaluated using the sieving method, maximum bite force (MBF) by pressure sensors, and masseter thickness by ultrasound.Measurements were performed 2, 12, and 24 months after SIO use. Repeatedmeasures ANOVA and paired Student's t-tests (p < 0.05) were applied.Results: Matrix exchange was the most prevalent maintenance event (83.6%), and no SIO was fractured during the entire follow-up. Satisfaction with the SIO stability decreased (p < 0.01) after 12 months. MP did not change between evaluations (p > 0.05). Conversely, MBF and masseter thickness improved after 12 and 24 months of SIO use (p < 0.05).Conclusions: Reinforced SIO did not fracture during 2 years but requires maintenance. It improves bite force and muscle thickness, maintaining MP values.Satisfaction with SIO stability decreased in the first year of use.

“…(4)(5)(6) In comparison to conventional dentures, implant-retained prosthesis will improve the denture retention, stability, chewing function, biting force as well as patient satisfaction. (7)(8)(9) It also has a relatively reduced cost and less surgical and prosthetic procedures compared to an implant-supported fixed prosthesis, which are considered particularly important for older edentulous patients.…”

Objective: To evaluate and compare the peri-implant marginal bone height changes in two implant retained overdentures constructed by either CAD/CAM technology or conventional processing techniques. Background:The digital denture using CAD/CAM technology has proved high beneficial to the elders and/or the compromised edentulous patient, as it can help decrease the treatment burden on the patient by reducing the clinical procedures, number of visits, treatment time, and incurred costs. Materials and Methods:Twenty completely edentulous patients participated in this study. The patients were randomly allocated to two equal groups of patients (Group A and group B). Group A patients received complete dentures constructed by conventional heat cured technique. Group B patients received complete dentures constructed by CAD/CAM technology. All the patients received two root form implants bilaterally in the canine regions following delayed loading protocol. Locator attachment was then used to retain the overdenture after 3 months healing period. Marginal bone height was radiographically evaluated at baseline, 6 and 12 months after implant loading.Results: There was a significant loss in marginal bone height around the supporting implants in each study group. However, no significant differences in marginal bone height were recorded between the study groups over the observation period (P > 0.05). Conclusion:Peri-implant marginal bone height changes with overdentures fabricated by CAD/ CAM technique are not different from those changes with overdentures fabricated by a conventional heat curd technique.
