A Follow-Up Study of Straight and Tapered Dental Implants in the Front Upper Jaw

This prospective study aims to evaluate 5-year clinical, radiographic, and patient-reported outcomes of implant-supported crowns and bridges placed on Neoss implants (ProActive Straight and Tapered) in the anterior maxilla (region 13 - 23). The study is conducted at Brånemarkkliniken, Public Dental Service, Västra Götalandsregionen, Sweden. While the treatment involves established methods and CE-marked devices, long-term data for this specific indication are limited.

The purpose of this study is to conduct a 5-year follow-up of implant-supported crowns and bridges placed on Neoss implants (ProActive Straight and Tapered) in the anterior maxilla (region 13 - 23). This is a prospective, single-center clinical follow-up study evaluating implant-supported prosthetic restorations in the anterior maxilla. Eligible patients receiving crowns or bridges supported by Neoss implants (ProActive Straight and Tapered) will be followed for 5 years. The treatment is based on established methods and CE-marked devices routinely used in clinical practice. However, long-term data for this specific indication are limited, and prospective follow-up is considered to be of clinical relevance. Clinical, radiographic, digital, and patient-reported outcomes will be assessed at prosthetic delivery (baseline), and at 1-year and 5-year follow-ups. The study aims to evaluate the performance of Neoss implants (ProActive Straight and Tapered) as support for single crowns and bridges after 5 years, with respect to complications, function, aesthetics, and patient satisfaction.

No prior bone augmentation required at the implant site. The implant site must be free from signs of infection. Exclusion Criteria: Individuals under 18 years of age. Individuals unable to provide informed consent due to disease, mental disorder, impaired health status, or similar conditions.
