Use of a single implant to retain mandibular overdenture: A preliminary clinical trial of 13 cases

Abstract

Background/purpose: Given that many patients find the cost of mandibular rehabilitation through complete overdenture implants to be beyond their financial scope, many seek a more affordable treatment. The aims of this study were to compare the clinical outcomes of single mandibular implant-retained overdentures versus that of complete dentures. Materials and methods: Thirteen edentulous patients with a mean age of 71 years were enrolled in this investigation. They were treated with a single implant inserted into the mandibular midline, followed by rehabilitation with complete dentures. The mandibular dentures were adhered with a locator or magnetic attachment after 10 weeks of adaptation.-Patient satisfaction was assessed by means of a visual analogue scale(VAS) questionnaire both on the day of attachment connection and 3 months later. Chewing efficiency was assessed by a sieve test before and after connecting the attachment. Within-subject comparisons were performed either by using paired-sample t-tests or Wilcoxon signed-rank tests to test patient satisfaction and chewing efficiency (P Z 0.05). Results: No implants were lost nor were denture fracture found during the observation period. Significant improvements were observed in all parameters of patient satisfaction (with P values ranging from <0.001 to w0.043) after attachment of the mandibular dentures with a single midline implant. Furthermore, the objective chewing efficiency of patients significantly improved after implant connection (P<0.001).

Comparison Between Patient Satisfaction And Biting Force In A Single Implant Overdenture And Two-Implants Overdenture: A Randomized Clinical Trial

“…This supports the argument that the implant overdenture produced a significant patient satisfaction than a conventional complete denture regardless the implant number whether one or two implants. [14,21,22] The explanation for this is that the implant improves retention, stability, and masticatory performance to a large extent which seems to be logic and in accordance with most previous studies that done on this subject. [13,[23][24][25][26][27][28] Between the groups, at baseline and at 3-month follow-up periods, the difference in the patient satisfaction between single and two implant groups was not significant which was compatible with the result of many previous studies.…”

Single Implant Retained Overdenture Treatment Protocol: A Systematic Review and Meta‐Analysis

“…The data extracted from the publications included were analysed and stratified based on the following (Table ). The SIROD treatment was primarily indicated in edentulous patients with atrophic mandibles, complaining of compromised retention and stability of the mandibular dentures . A minimum ridge height of 10 mm and width of 4 mm was considered adequate to allow for placement of the symphyseal implant .…”

A minimum ridge height of 10 mm and width of 4 mm was considered adequate to allow for placement of the symphyseal implant . Orthopantomography, and conventional tomography, were the most commonly employed diagnostic imaging techniques for treatment planning.…”

“…This treatment modality provided clinicians with a successful, cost‐effective and functional alternative for the management of patients presenting with mandibular ridge resorption that rendered conventional complete dentures cumbersome. Several studies have reported the success and clinical viability of single implant‐retained overdentures (SIROD) . But, these publications presented differences in workflow and were associated with a plethora of complications.…”

Evaluation of Single Implant Assisted Mandibular Overdenture in Diabetic Patients

“…Patients in good general health conditions are best candidates for implant therapy, however since single implant-assisted overdenture is a simplified and less invasive approach, it is a more feasible option for older and/or debilitated patients who have health restrictions or systemic conditions that increase the risk of extensive implant surgical procedures. If any systemic condition or disease is present, like diabetes or hypertension, it must be controlled and properly managed as part of the treatment planning and during the surgical interventions 20,21 .…”
