Mandibular implant-retained overdenture: a clinical trial of two anchorage systems.
نویسندگان
چکیده
This in-vivo study aimed to investigate the load on the working-side implant and on the edentulous distal mucosa of the nonworking side in a mandibular implant-retained overdenture (MIR-OVD) anchored to 2 implants by either a ball- or a clips-and-bar attachment. Three female patients were provided with duplicate dentures anchored in the 2 ways. Strain on the implant was investigated using a strain-gauged abutment, and load on the mucosa was measured using a suitably placed load cell. Ball attachments appeared to provide greater stability to the MIR-OVD, since load was more evenly distributed onto the distal mucosa of both sides. When the MIR-OVD was bar-anchored, axial load on the working-side abutment increased.

Single Versus Two Dental Implant Retained Mandibular Overdenture: Study Protocol for a Randomized Controlled Trial
Background: The consensus is that the standard treatment of choice for the edentulous mandible should be a two implant retained mandibular overdenture. Some clinicians have tried single median implant to retain the mandibular overdenture, however, there is lack of scientific information with single implant retained mandibular overdenture. Therefore the purpose of the current randomized clinical...
متن کاملMandibular implant-retained overdenture: finite element analysis of two anchorage systems.
Transmission of masticatory load in mandibular implant-retained overdentures was evaluated using a three-dimensional finite element model. The reaction forces on the distal edentulous mucosa and the stress on the perimplant bone were compared in overdentures retained either by two ball attachments or by two clips on a bar connecting two implants. In the finite element model, a 35 N load on the ...
متن کاملImplant Retained Overdenture Improves the Retention and Stability by Using a Locator System in a Mandibular Edentulous patient: A Case Report
Abstract Complete maxillary and mandibular dentures have been used as a conventional treatment of edentulous patients for longer than a century. Suitable complete maxillary dentures are usually well tolerated but many patients struggle to chew and swallow with the complete mandibular denture because it is too unstable. Previous studies have shown that a mandibular two-implant retained overdentu...
متن کاملEarly Loaded Single Implant Reinforced Mandibular Overdenture
Rehabilitating atrophied mandible with two-implant supported denture is a common treatment modality for implant retained removable overdenture in mandible. This paper aims to design a treatment modality where single implant reinforced overdenture is fabricated for a severely atrophied mandibular ridge with early loading protocol. Results of studies have shown that a single implant mandibular ov...
متن کاملSurgical and prosthetic planning for a two-implant-retained mandibular overdenture: a clinical report.
A 2-implant-retained mandibular overdenture is considered by some to be the standard of care for mandibular edentulism. Compared to a conventional complete denture, an implant-retained overdenture requires more thorough planning. Careful consideration is necessary regarding the 3-dimensional orientation of the implants to ensure adequate horizontal and vertical space for prosthetic components. ...
