Association of Force Distribution and Bone Resorption
Association of Occlusal Force Distribution and Bone Resorption in Implant Supported Overdentures
研究概览
详细说明
A total of forty-six edentulous patients participated in this clinical study divided into two groups as following; complete denture group (CD) consists of 23 patients wearing conventional complete dentures and another Implant overdenture group (IOD) consists of 23 patients wearing mandibular complete overdenture with 2 implants. Two panoramic radiographs at baseline and in a follow-up to 7 years were used to measure the ratio of bone changes between the anatomical bone area and the reference area in the maxillary and the mandibular ridges. The occlusal contacts percentage of force in maximum intercuspation anteriorly and posteriorly were recorded for both groups by using T-Scan III system.
Oral and written information in English or Malay language, regarding the study, was provided and written consent obtained before enrolment.
