NCT06554041

Brief Summary

The goal of this clinical trial is to learn how different materials used in dental implants affect the surrounding gum tissue in adults who need dental implants. The main questions it aims to answer are: How do different materials (titanium, PEEK, zirconia, and lithium disilicate) affect inflammation around dental implants? What changes occur in inflammation markers in the gum tissue after 3 and 6 months? Researchers will compare the different materials to see which one causes the least amount of inflammation. Participants will: Receive dental implants made from different materials. Have samples of fluid from around their implants collected for analysis at 3 and 6 months. Undergo regular dental check-ups to measure gum health, such as bleeding and pocket depth around the implants.

Outcome Measures

Primary Outcomes (1)

  • Concentration of Inflammatory Biomarkers in Peri-Implant Crevicular Fluid

    The primary outcome measure will evaluate the concentration of inflammatory biomarkers in the peri-implant crevicular fluid, including IL-6, IL-8, IL-10, IL-17, TNF-alpha, IL-12, IL-1-beta, and IL-4. These biomarkers all have the same unit and will be measured to assess the inflammatory response of peri-implant soft tissue to different prosthetic materials (titanium, PEEK, zirconia, and lithium disilicate). The goal is to determine which material induces the least amount of inflammation, indicating better biocompatibility and a lower risk of peri-implantitis.

    3 and 6 months post-implantation

Secondary Outcomes (2)

  • Clinical Measurements of Bleeding on Probing (BOP) and Pocket Depth

    3 and 6 months post-implantation

  • Clinical Measurements of Pocket Depth

    3 and 6 months post-implantation

Study Arms (4)

Dental Crown with Titanium-Abutment

EXPERIMENTAL

Participants in this arm will receive dental implants and single crowns made from titanium. The impact of titanium on peri-implant soft tissue health will be evaluated by measuring inflammatory markers and clinical outcomes such as bleeding on probing and pocket depth at 3 and 6 months post-implantation.

Device: Dental Crown with Titanium-Abutment

Dental Crown with PEEK (Polyetheretherketone)-Abutment

EXPERIMENTAL

Participants in this arm will receive dental implants and single crowns made from PEEK. The study will assess the biocompatibility of PEEK by examining inflammatory responses and clinical outcomes, including bleeding on probing and pocket depth, at 3 and 6 months post-implantation.

Device: Dental Crown with PEEK (Polyetheretherketone)-Abutment

Dental Crown with Zirconia-Abutment

EXPERIMENTAL

Participants in this arm will receive dental implants and single crowns made from zirconia. The effects of zirconia on peri-implant soft tissue will be analyzed by measuring the levels of inflammatory markers and observing clinical outcomes such as bleeding on probing and pocket depth at 3 and 6 months post-implantation.

Device: Dental Crown with Zirconia-Abutment

Dental Crown with Lithium-Disilicate-Abutment (e.max)

EXPERIMENTAL

Participants in this arm will receive dental implants and single crowns made from lithium disilicate (e.max). The study will evaluate the biocompatibility of e.max by measuring inflammatory markers and clinical outcomes, including bleeding on probing and pocket depth, at 3 and 6 months post-implantation.

Device: Dental Crown with Lithium-Disilicate-Abutment (e.max)

Interventions

Participants in this clinical trial will receive dental implants and single screw-retained crowns made from one of four different materials: titanium, PEEK (Polyetheretherketone), zirconia, or lithium disilicate (e.max). The implants will be placed in the posterior region of the mandible or maxillae. The study will evaluate the impact of these materials on peri-implant soft tissue health by measuring inflammatory markers in the peri-implant crevicular fluid and assessing clinical outcomes such as bleeding on probing and pocket depth at 3 and 6 months post-implantation.

Intervention Model
PARALLEL
Model Details: This clinical trial employs an interventional study model with a parallel assignment. A total of 40 edentulous patients, will be randomized into four groups. The study is open-label, meaning that both the researchers and the participants will know which material is being used for each patient. This design is intended to evaluate the impact of these different materials on the health of the peri-implant soft tissue by measuring inflammatory markers and clinical outcomes such as bleeding on probing and pocket depth over a six-month period.
