Abstract

Aim: This study was performed to evaluate Ball versus locator attachment for immediately loaded two Trabecular Implants supported mandibular over denture.
Material and methods: Eighteen patients will initially receive treatment with a complete denture, and subsequently, two Trabecular implants will be placed in the mandible at the canine region .On the day of implant insertion, eighteen implants supported by an overdenture will be loaded immediately . Patients will be split into two equal groups : Group A: Using a ball attachment the two Trabecular implants were connected . Group B: Using a locator attachment the two Trabecular implants were connected . changes in bone height around the implants in vertical and horizontal planes were assessed radiographically using CBCT at the time of overdenture insertion (T0), six months (T1), and twelve months (T2) after insertion, the health of the peri-implant tissue was assessed for at T0,T1 and T2 the Plaque and Bleeding Indices were utilized .Pocket depth was determined and implant stability.
Results: There was no significant difference in the vertical bone loss between attachments at T6. In contrast to Locator attachments, ball attachments at T12 showed a significant higher vertical bone loss. There was a significant variation in the horizontal bone loss for both attachments between time intervals. For both attachments, horizontal bone loss significantly increased from T6 to T12.
Conclusion : locator attachment was associated with reduced vertical and horizontal bone loss around the implant and also reduced peri -implant tissue inflammation and higher implant stability than ball attachment.
