Clinical Trial Summary

A randomized clinical trial (RCT) was designed. The participants were randomly allocated into either of the two groups intervention or control group each of 14 participants. Participants in control group (Group-A) received conventional manufactured implant overdenture while participants in intervention group (Group-B) received CAD-CAM manufactured implant overdenture.

Description:

Introduction: Mandibular single implant overdenture is a well-established treatment modality that address limited financial resources of patients and simultaneously enabled the management of conventional complete denture problems. CAD/CAM technology helped to mitigate the problems encountered with conventional fabrication techniques, which results in improved dentures fit and retention. Therefore, the aim of the current trial study was to evaluate whether overdentures fabricated using CAD/CAM printed technology exhibited improved patient satisfaction, denture retention, implant survival rate and decreased post-insertion maintenance or not compared to overdentures manufactured using conventional techniques. Methods: A randomized clinical trial (RCT) was designed. The participants were randomly allocated into either of the two groups intervention or control group each of seven participants. Participants in control group (Group-A) received conventional manufactured implant overdenture while participants in intervention group (Group-B) received CAD-CAM manufactured implant overdenture.
