Dental Implant Osteointegrated With The Residual Root

This case report presents the long-term prognosis of an implant resulting in late failure with an osteointegrated root remnant on the fixture 11 years after implant placement. A 68-year-old female patient experienced issues with a maxillary right 4-unit implant-supported bridge placed 11 years ago. During removal, an osteointegrated root remnant was discovered on the middle supporting implant, which had been inadvertently placed over it. Clinicians should be cautious with retained root remnants, as they may impact osteointegration. However, both the implant and root fragment were osteointegrated without adverse effects.

Custom-Made Zirconia Crowns and 3D-Printed Resin Crowns Versus Ready-Made Zirconia Crowns in Primary Molars

The main problem introduced in this study is the aggressive reduction needed for ready-made zirconia crowns to be passively fitted. In addition, its relatively expensive cost and wear of the opposing tooth structure. In this study, different crown materials will be introduced, such as customized zirconia crowns and novel 3D printed resin crowns who may offer better adaptability and gingival health and are relatively cost effective. The proposed study will help in increasing studies of different crown materials for primary teeth
