clinical trial

The goal of this clinical trial is to record the esthetic outcome of the 3d printed hybrid resin crowns. It will also test which method of fabrication is advantageous than the other one. The main questions it aims to answer are:

Does any of the fabrication methods differ in its esthetic outcome?

Researcher will compare 3d printing fabrication to conventional fabrication method which is the milling technique to see if 3d printing of hybrid resin serves patients a better crown's esthetic outcome.

Participants will:

Receive a crown after implants are osseointegrated Visit the clinic once every 3 months for checkups and tests Keep records of level of patient's satisfaction.

Inclusion Criteria:

• Age: between 18 and 70 years old at the time of screening.
• Patients with implants placed and in need for crown restoration
• Medically free with no systemic diseases.
• Good oral hygiene with no active periodontal disease.
• Patient's having adequate interocclusal and mesiodistal restorative space for the fabrication of a single implant-supported crown.
• Patients willing and able to provide written informed consent for participation in the study, understanding its risks, benefits, and alternative treatments.

Exclusion Criteria:

• Uncontrolled systemic diseases (e.g., uncontrolled diabetes, severe cardiovascular disease, active autoimmune disorders, uncontrolled thyroid dysfunction).
• Patients with composite restoration on the labial/buccal surface implant's neighbouring.
• Immunocompromised patients or those undergoing immunosuppressive therapy.
• Patients undergoing radiation therapy to the head and neck region, or chemotherapy.
• Patients currently on or with a history of medications known to significantly affect bone metabolism (e.g., long-term bisphosphonates, corticosteroids).
• Pregnancy or lactation.
• Known allergies to titanium, resin components, or any other materials used in the study (e.g., composite, zirconia).
