“…Rodrigues (2000) presented clinical cases of mandibular implant overdenture using cast metal reinforcement. These overdentures had a bar attachment, and its reinforcement was an over-the-clip-ofthe-bar attachment.…”

“…As a result, the overdenture around the coping is thin, and the overdenture is susceptible to deformation or fracture (Ohtani et al, 1991;Rodrigues, 2000). Ohtani et al (1991) examined denture repair cases (n =237) and found that the most frequent fractures of resin denture bases occurred in areas adjacent to abutment teeth in overdentures.…”

“…Ohtani et al (1991) examined denture repair cases (n =237) and found that the most frequent fractures of resin denture bases occurred in areas adjacent to abutment teeth in overdentures. Fracturing of the denture base around a coping is a longstanding problem and common clinical occurrence in prosthodontic practice (Polyzois et al, 1996;Rodrigues, 2000).…”

Prolonged edentulism has been associated with progressive alveolar resorption. To reduce alveolar bone resorption and to preserve proprioception, Overdenture can be the treatment modality. Retention of denture can be increased by using attachments.Bar attachment helps in splinting and retention of the appliance. But the diminished denture base dimensions required to accommodate bar attachment and tooth abutments render the prosthesis more susceptible to fracture. This case report describes tooth supported overdenture with bar attachment and the procedure for reinforcement of the denture base with metal framework.

“…Moreover, fracture of denture bases tends to occur more frequently around abutments due to insufficient thickness of acrylic resin resulting from attachment thickness (11). Despite the annual global cost of repairing fractured dentures, repaired dentures are not so strong or functional as intact ones (12).…”

Objective: To evaluate the effect of glass fibers on acrylic resin fracture strength in simulated implant-supported overdenture (IOD) abutments. Methods:A model was designed to simulate the clinical situation of an IDO (50×12×1.5 mm). Thirty models were divided into three equal groups: ten models not supported with glass fibers (control group), ten models with one layer of glass fibers (experimental group I) and ten models with two layers of glass fiber (experimental group II). All models were exposed to a three-point bending test, and fracture loads were analyzed using a one-way analysis of variance (ANOVA) followed by Bonferroni post-hoc test.Results: IOD models reinforced with two layers of glass fibers (experimental group II) showed a mean ultimate load at fracture of 48.69 ± 3.71 Newton (N) compared to mean loads of 32.78 ± 2.41 N and 24.42 ± 2.73 N for the models reinforced with one layer (experimental group I) and non-reinforced with glass fibers (control group), respectively. ANO-VA showed a statistically significant difference between the three groups regarding the mean ultimate load at fracture, and Bonferroni post-hoc test showed statistically significant differences between both experimental groups and the control group as well as between experimental group I and experimental group II. Conclusions:The fracture strength of IDO abutments increases significantly by the addition of acrylic resin preimpregnated with glass fibers, even when the thickness of acrylic is thin.

“…A rigid attachment system for the overdenture seems to give better results than a structure with some micromovement , Jemt et al 1992, Smedberg et al 1993. The reinforcement of implant overdenture bases with chromium alloys makes the denture base more fracture resistant (Rodrigues, 2000, Gonda et al 2007. Also, because of the increased strength, the thickness of the acrylic resin may be reduced.…”
