Effect of prefabricated bar design with implant-stabilized prostheses on ridge resorption: a clinical report.
This investigation was concerned with the resorption of the posterior mandibular residual ridge in patients wearing mandibular overdentures supported by either parallel-sided bars (rigid joint) or oval straight bars (resilient joint) on two activated implants. Rotational tomographs were taken shortly after implant placement and up to 8 years later. Using proportional measurement, the area of re...
متن کاملComparison of the Effect of Ball and Bar Attachment Designs on Retention and Stability of Mandibular Implant-Supported Overdentures
Objectives: The present study evaluated the effect of bar and ball attachment designs on retention and stability of a mandibular overdenture supported by four implants. Methods: An edentulous mandibular acrylic resin model with four implants in the anterior part of the ridge (A, B, D and E) was fabricated. A metal framework simulating the overdenture was also fabricated. Totally, 30...
متن کاملComparison of prefabricated and custom-made bars used for implant-retained mandibular complete overdentures.
PURPOSE To compare prefabricated and custom-made bars used for implant-retained mandibular complete overdentures. MATERIALS Ten completely edentulous patients were selected for replacement with dental implants. Each patient received 2 (press-fit) dental implants, 1 implant on each side in the canine regions of the mandible. The implants were left submerged (unloaded) for a healing osseointegr...
متن کاملRitva Kuoppala Outcome of Implant - Supported Overdenture Treatment
The retention of a complete denture and the patient’s adaptation varies considerably among different individuals. Resorption of the edentulous alveolar ridge differs greatly and some patients need implant-retained overdentures to enable adequate retention of their prostheses. In some extreme cases it is necessary to increase the volume of the alveolar ridge with bone grafts. The aim of this stu...
متن کاملRehabilitation of resorbed mandibular ridges using mini implant retained overdentures: A case series with 3 year follow-up
With the increasing average life expectancy of human beings, the need to cater geriatric patients is ever increasing. Complete dentures are an indispensable tool in this regard. The loose and unstable lower complete denture owing to residual ridge resorption is one of the most common problems faced by edentulous patients. Dental implant retained overdentures have emerged as an efficient treatme...
