Summary

The aim of this clinical study is to evaluate two different implant-abutment connection design on preserves gingiva and bone health in the long term. As part of this study, two different implant systems will be applied to the posterior edentulous areas on both sides of the mouth. Implants featuring a new macro-design and a special surface technology (TiUltra surface and N1 system), aimed at accelerating tissue healing, will be placed in one area; meanwhile, implants with a conical design and the same special surface technology, which are widely used in clinical practice (Nobel Active), will be placed in the other area. Procedure for Participants First, an intraoral examination will be performed, and CBCT will be taken to assess suitability for the procedure. Surgical Procedure: Implant placement. Prosthetic Phase: Once healing is complete, impressions will be taken, and porcelain teeth will be placed on the implants. Follow-up Appointments: Follow-ups will be conducted at 1, 3, 6, and 12 months following the placement of the teeth. During these check-ups, gingiva health will be assessed, and X-rays will be taken to observe changes in bone levels.
