Clinical and Radiographic Evaluation of Bone and Tissue Level Single Unit Implants: Two-piece Abutment Concept

Dental implants have become one of the most common treatments used for the rehabilitation of lost teeth. The success rate of dental implant treatment is quite high. One of the criteria used for long-term implant success is the evaluation of radiographic marginal bone loss. Implants are used at the bone and tissue level in implant treatment. In this study, it was planned to use 20 implants of the same brand, with a single implant in the bilateral posterior regions in 10 patients.The study will be designed as split-mouth. The implant will be placed at the bone level with the same protocol in the two edentulous areas and the flap will be closed primarily. After 3 months, the substructure of the two-piece abutment concept system will be placed in a region during the healing head placement stage, and the bone level implant will be converted to the tissue level. A conventional healing cap will be placed in the other area. Periapical radiographs will be taken from the patients who participated in our study, as in all implant patients, during the pre-surgical planning phase and after implant placement. With the control periapical radiographs to be taken as a result of one-year follow-up, the marginal bone loss amount in the implants will be evaluated using soft-ware. Clinical measurements will be taken in all patients at the prosthetic loading session and 1 year after loading.
