Summary: This study evaluated the effects of different fabrication techniques and materials on implant-supported mandibular overdentures with a Hader bar attachment. The use of converting adapters on implants was found to decrease force transmission and improve stress distribution. The type of material used for bar fabrication did not significantly influence stress values.

Summary: This study aimed to demonstrate the clinical outcomes of implants supporting mandibular overdentures in edentulous patients using guided surgery, showing a 100% success rate for the implants but with some patients experiencing mechanical prosthodontic complications and peri-implantitis.

Summary: This study examined the retentive characteristics of different retentive element materials and their performance after thermocycling using a two implant-retained mandibular overdenture model. The results showed that the percentage of retention loss significantly increased over time for PEEK, nylon, and PVS silicone. Nylon and PEEK, which have strong polar groups, exhibited a higher rate of retention loss compared to polyvinylsiloxane.

Summary: This study reviewed the application and maintenance of attachment systems in implant-retained overdentures. The initial retention force of cylindrical systems is higher, but this advantage decreases over time. Plastic retention devices wear out faster but have similar maintenance rates compared to metal ones. There is no clear superiority between ball and cylindrical systems.

Summary: This study found that patients treated with different types of implant treatment for edentulous mandible were at risk of post-treatment prosthodontic complications and required regular recall visits to ensure satisfactory function and prevent further problems. Overdentures required higher rates of maintenance visits, particularly for replacement of the retentive inserts, while fixed implant prostheses required longer clinical times for management of complications when compared to overdentures.

Summary: The study investigated the long-term performance of tooth-implant-supported and solely implant-supported double-crown-retained overdentures for complete restoration of the jaw over a period of up to 11 years. The results showed high survival and success rates for both types of restoration, but common minor complications required significant aftercare.

Summary: This crossover clinical study aimed to evaluate and compare patient satisfaction and masticatory performance of mandibular two implant overdentures with zirconia bar and cobalt chromium bar attachments. The results showed that patient satisfaction with zirconia bar was significantly higher than with Co-Cr bar in terms of appearance, time, hygiene, recommend procedures, and overall experience.

Summary: The study found that patients interested in mandibular implant-supported complete denture are mainly influenced by their previous experience with mandibular complete dentures and dissatisfaction with retention.

Summary: The use of implant-supported prostheses significantly improves masticatory function compared to conventional rehabilitations, but stable bioavailability is observed for most nutrients, especially in complete edentulous patients. These results highlight the importance of a multidisciplinary approach, involving nutrition specialists, during oral rehabilitation to enhance food choices and promote health benefits.

Summary: This in vitro study compared the wear behavior of two different attachment systems of dissimilar materials in mandibular implant-retained overdentures. The study found that the attachment system with a titanium-to-titanium interface had more wear than the system with a titanium-to-nylon interface.

Summary: The purpose of this study was to evaluate and compare the initial retention force of three resilient unsplinted attachment systems for implant-retained mandibular overdentures. The results showed that the initial retention force varied among the three attachment systems, with the Locator R-Tx & REG; having the most comprehensive range, the Novaloc & REG; providing more reproducible values, and the Ball System requiring activation by the operator.

Summary: This study compared the effects of implant overdentures and conventional dentures on patients' satisfaction and quality of life. The results showed that implant overdentures were preferred by patients in terms of overall satisfaction, speaking ability, comfort, esthetics, and stability.

Summary: The concept of a single midline implant in the edentulous mandible has been a topic of controversial discussion. Initial clinical results showed high implant survival rates and significant improvements in oral comfort, function, patient satisfaction, and oral health-related quality of life for edentulous patients. However, these trials had limitations in terms of sample size and follow-up period. Recent clinical investigations with longer-term observation periods have provided more insights. This overview aims to present the current literature and highlight clinical issues.
