“…A similar tendency has been observed for patients treated with fixed prostheses, where the majority were generally satisfied with this type of rehabilitation (1,2,30). Therefore, the present results are similar to those already reported, indicating that patients treated with implant-supported total prostheses, whether removable or fixed, are contented with the result, especially due to the fact that previously they had worn total conventional prostheses, which were ineffective in terms of retention, stability and support (5).…”

“…Assessments of rehabilitation treatments must consider patients' opinions as a variable of treatment success (3). Patients often express dissatisfaction with their lower arch dentures (4), and complaints include reduced retention stability of conventional dentures, and difficulties with mastication and verbal communication, all due to bone resorption of the alveolar process with time (5).…”

Oral health impact profile and prosthetic condition in edentulous patients rehabilitated with implant-supported overdentures and fixed prostheses

The complexity of rehabilitation for totally edentulous patients makes it necessary to devise treatment strategies that meet the patients' expectations in terms of function, esthetic, psychological, and social aspects. The aim of this study was to i) compare the satisfaction of edentulous patients who had been rehabilitated with implant-supported overdentures and fixed prostheses in the mandible, and ii) assess the technical aspects of the prostheses in relation to patient satisfaction. This was a cross-sectional study involving 30 patients, 15 of whom had been rehabilitated with implant-supported overdentures and 15 who had been treated with fixed prostheses. The patients answered the OHIP-EDENT questionnaire, validated for the Brazilian Portuguese language, to assess satisfaction. Also, patients underwent clinical examination to assess the condition of their prostheses. Statistical analysis using the Mann-Whitney U-test revealed no significant differences in satisfaction between patients with overdentures and those with fixed prostheses. Likewise, Fisher's exact test demonstrated no significant differences in patient satisfaction concerning the condition of the prostheses as evaluated by the prosthodontist. It was concluded that both types of prostheses were perceived as being equally satisfactory by edentulous patients, and that the condition of the prostheses did not influence individual satisfaction in

“…Additionally, there are complications associated with conventional removable dentures, fixed crowns and bridges; for example, the reduced bearing area that supports the removable prosthesis due to the gradual bone resorption of the residual ridge following tooth extraction. Thus, using endosseous titanium implants is more convenient with better functionality than conventional dentures [4].…”

Abstract:Recently, an increasing amount of research has focused on the biological and mechanical behavior of highly porous structures of metallic biomaterials, as implant materials for dental implants. Particularly, pure titanium and its alloys are typically used due to their outstanding mechanical and biological properties. However, these materials have high stiffness (Young's modulus) in comparison to that of the host bone, which necessitates careful implant design to ensure appropriate distribution of stresses to the adjoining bone, to avoid stress-shielding or overloading, both of which lead to bone resorption. Additionally, many coating and roughening techniques are used to improve cell and bone-bonding to the implant surface. To date, several studies have revealed that porous geometry may be a promising alternative to bulk structures for dental implant applications. This review aims to summarize the evidence in the literature for the importance of porosity in the integration of dental implants with bone tissue and the different fabrication methods currently being investigated. In particular, additive manufacturing shows promise as a technique to control pore size and shape for optimum biological properties. OPEN ACCESSMetals 2015, 5 1903

“…[3][4][5][6][7][8] A number of randomized-controlled trials reported significantly increased patient satisfaction and a positive impact on quality of life with implant-retained mandibular overdentures compared to conventional dentures.

1.-Effect of bar design and dimensions on bar extension fracturePrevention of distal extension cantilever fracture in mandibular overdentures. Materials and methods:The 2 nd moment area and static strength were calculated for 11 frequently used bar designs using finite element analysis (FEA). For two specific designs (Ackermann round ∅ 1.8 mm and Dolder Y-macro, the former with and without a support rib) additional physical static and fatigue strength tests were included. Results:The FEA static strength data corresponded well to the 2 nd moment area (a similar ranking when maximum allowed force was considered). The application of a rib support (Ackermann ∅ 1.8 mm) and limitations of the bar extension length (6 mm for the Ackermann ∅ 1.8 mm, 8 mm for the Dolder Y-macro) allowed the bars to exceed 5x10 6 cycles of 120 and 250 N respectively, before fracture. The region of highest stresses in FEA corresponded well with the locations of the fractures observed in static-and fatigue testing. Conclusions:With some simple guidelines/modifications, the number of bar extension fractures can be reduced significantly. Clinical significanceThis study focusses on distal bar extensions which improve the positioning of an implant supported overdenture. By combining laboratory testing and finite element simulations we aim to: (1) explain why fractures occur (dependent on physical characteristics of the bar), and (2) give clinical guidelines on how to prevent such fractures. 2.-Effect of bar design and dimensions on bar extension fracture
