Summary:

Objective: The general objective is to compare the placement of standard implants with a surface photofunctionalization technique based on ultraviolet C radiation (UVC), having as working hypothesis that this photofunctionalization will accelerate the bone apposition on the implant surface and increase the amount of bone that binds to the implant, making it possible to load these photofunctionalized implants in less time.

Design: Pilot, clinical, randomized, prospective, controlled, single-center, prospective study.

Scope of the study: Master's Degree in Oral Surgery and Implantology. Faculty of Dentistry. Complutense University of Madrid.

Subjects of the study: patients attending the Master's Degree in Oral Surgery and Implantology for rehabilitation with dental implants, regardless of the sector in which they have missing teeth.

Key words: ISQ (implant stability quotient), inmediate loading, UVC, dental implants.

Inclusion Criteria:

• Patients over 18 years of age.
• Patients requiring dental implant surgery with or without bone or soft tissue regeneration surgery.
• Acceptance of the informed consent document.

Exclusion Criteria:

• Subjects with systemic diseases leading to untreated or uncontrolled haemostasis or coagulation disturbances.
