Clinical Trial: Association of Force Distribution and Bone Resorption
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: Association of Occlusal Force Distribution and Bone Resorption in Implant Supported Overdentures
Brief Summary: To investigate the residual ridge resorption at anterior and posterior maxillary and posterior mandibular ridges among conventional complete dentures and implant overdenture wearers, and determine its association with the relative occlusal forces distribution, treatment groups and other patient variables.
Detailed Summary:
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.
