Abstract

Complete anodontia and alveolar ridge resorption are responsible for lack of retention and stabilization of conventional acrylic lower denture.
Hybrid prostheses on 4 implants placed immediately in the first 7 days is therapeutic solution which allows patients better chewing and increased effective masticatory force.
Aim: The study aims to assess the functional and subjective treatment outcomes of full-arch fixed overdenture hybrid rehabilitation.
Material and Methods: 60 patients with hybrid prostheses over 4 implants were included in the study. The measurement of the masticatory force was done in the chewing center in the projection of the distally placed implant. Electro-gnathic-dynamometer measured the force of the muscle elevator and depressor of the mandible. Sensor was placed in plastic bite templates and the force value was registered three times.
Results: The mean masticatory forces measured in the chewing center before implants and overdenture were 95.7 N. One month later with the prosthesis the value was increased to 185.6 N and after 18 months 186.2 N.
Conclusion: There is significant increase in masticatory force in area of ​​the distal implant. This is indicating increased resistance to load and higher efficiency of the chewing process after the treatment.

Keywords: overdenture, full-arch, hybrid prosthesis
