“…However, instability of the maxillary denture with mandibular implantretained overdentures has been reported in number of studies. Nevertheless, others found no differences between mandibular overdenture and mandibular complete denture groups related to complaints about the maxillary denture [4], [14], [15], [16].…”

PURPOSE: This study aimed to compare patients’ satisfaction with mandibular overdentures retained by three-splinted implants versus conventional complete denture wearers during a 7-year follow-up study period. MATERIALS AND METHODS: Thirty edentulous male patients (mean age: 60 years) were carefully selected and divided into two equal groups. All patients received a new set of complete dentures. Group I patients received three implants in the anterior mandible and were connected after 3 months with bars, clips, and loaded. Group II patients received conventional complete dentures. Patients’ satisfaction was recorded for both groups at 3 weeks (baseline) and after 1, 3, 5, and 7 years. Patients were then asked to grade their overdentures/dentures on a visual analog scale and written questionnaire to evaluate their overall satisfaction. RESULTS: Satisfaction scores of Group I patients were found to be statistically significantly higher than that of Group II patients (p < 0.05) at 3, 5, and 7 years follow-up, meanwhile, no statistically significant difference was found at baseline or after 12 months. CONCLUSION: The long-term results suggest that three-implant-retained mandibular overdenture with a clip-bar attachment appears to be a successful rehabilitation strategy which is superior to conventional dentures for patients with advanced ridge resorption.

“…Findings obtained in a current systematic review study show that there is no significant difference between bar, ball, and O-Ring attachment types in terms of retention, mastication, maximum occlusal force, and bone loss. 42 In the future, with the attachment types evaluated in this study, long-term clinical studies that include bar attachment systems should be conducted.…”

“…Moreover, prosthetic restoration of the severely resorbed edentulous mandible is challenging due to the pattern of bone resorption and the presence of the alveolar nerve [ 2 ]. Compared to a maxillary denture, a mandibular denture has a base with a longer periphery and smaller contact area between the alveolar ridge and the denture base; fixed mucosa are also frequently lacking.…”

Rehabilitation of extremely atrophic edentulous mandible in elderly patients with associated comorbidities: a case report and proof of concept

Background Oral rehabilitation of the atrophic mandible is, most of the time, a challenging procedure, especially in elderly patients with associated comorbidities. Case presentation This clinical report describes the rehabilitation of an extremely atrophic mandible using an overdenture supported by four splinted implants, two of which are placed in the interforaminal region and the other two bypassing the inferior alveolar nerve at the level of the antegonial notch. A passive-fit bar structure splinting the four inserted implants was designed to compensate for mandibular flexure, to reduce the amount of strain on the implants, and avoid bone resorption and prosthetic failure. The 14-month postoperative cone-beam computed tomography (CBCT) and the clinical follow-up showed the bilateral integrity of the inferior alveolar nerve and the successful restoration of the atrophic edentulous mandible with a significant improvement in the patient’s quality of life. Conclusions The applied technique depicts several benefits such as a minimally invasive approach, reduced number of surgical interventions, reduced total treatment time, reduced treatment costs, and higher psychological acceptability.
