Immediate Loading of Edentulous Mandible With Prefabricated Bars: A Long-Term Study of 7 Years.

Purpose: To present clinical data from a 7-year follow-up study of edentulous mandibles rehabilitated according to an immediate loading protocol with prefabricated bars.

Materials And Methods: Forty-four implants were inserted in 11 patients and were evaluated by means of resonance frequency analysis (RFA) and clinical and radiographic examination.

Results: Ten patients returned for the 7-year evaluation and presented no implant loss.

Benefits of rehabilitation with implants in masticatory function: is patient perception of change in accordance with the real improvement?

This study aimed to compare the index of satisfaction and masticatory function of edentulous patients before and after rehabilitation and to evaluate if patients' perception of the changes in their oral health status is in agreement with the results of masticatory performance test. Fourteen edentulous patients were rehabilitated with lower implant-supported fixed prosthesis and upper removable dentures. Index of satisfaction and masticatory capacity (subjective analysis) and performance test (objective analysis) were evaluated before and 20 days and 8 months after rehabilitation.

Implant stability measurements of two immediate loading protocols for the edentulous mandible: rigid and semi-rigid splinting of the implants.

Aim: Primary and secondary stabilities of immediately loaded mandibular implants restored with fixed prostheses (FP) using rigid or semi-rigid splinting systems were clinically and radiographically evaluated.

Methods: Fifteen edentulous patients were rehabilitated using hybrid FP; each had 5 implants placed between the mental foramens. Two groups were randomly divided: group 1-FP with the conventional rigid bar splinting the implants and group 2-semi-rigid cantilever extension system with titanium bars placed in the 2 distal abutment cylinders.

Occlusal concepts application in resolving implant prosthetic failure: case report.

The prosthetic management of a poor implant treatment is presented in this case report. The recommended occlusion concepts for implant-supported prostheses were applied for the resolution of the case. The rehabilitation of the posterior segments provided a mutually protected occlusion with adequate distribution of the axial and lateral bite forces with stable posterior occlusion.
