Abstract:
Objectives: In this study, the impact of occlusal adjustment by two different methods (T scan and articulating paper) on the variations in vertical bone height surrounding dental implants retained mandiblar overdenture by Peek bar.
Materials and Methods: 16 male patients whose mandibular and maxillary arches were completely edentulous with an age range above 55 years participated in this study. Both the right and left implants were inserted in canine areas Every patient was fitted with an implant mandibular overdenture retained by a CAD/CAM machined PEEK bar.
The patients were divided into two equal groups depending on the occlusal error detection and adjustment technique: Group I used the T scan III device to identify occlusal problems, At the same time Group II employed articulating paper for occlusal adjustment. During the follow-up period, radiographic evaluation was conducted using a digital periapical radiograph to assess the degree of vertical bone loss surrounding the dental implant.
Results: During the follow-up, it was shown that both groups I and II had increased vertical bone loss. When the two groups were compared collectively, group II showed significantly more vertical bone height alterations surrounding the implants than group I.
Conclusion: Within the limitations of this study, it is possible to conclude that using the T scan III device, as opposed to articulating paper, results in reduced vertical bone loss surrounding the dental implants and facilitates better occlusal adjustment in implant-retained lower overdentures.
