Safety Assessment of Placing a Single Dental Implant Without Antibiotic Prophylaxis in Simple Cases: A Pilot Study

2026年11月2日 更新者:Dang Tran Ngoc Hien、University of Medicine and Pharmacy at Ho Chi Minh City

Safety Assessment of a No - Antibiotic - Prophylaxis Protocol for Single - Implant Placement in Straightforward Cases: A Pilot Study

This pilot study will examine whether a single dental implant can be placed safely without giving antibiotics before or after surgery in patients with straightforward cases in Vietnam. Adults who are generally healthy, have one missing back tooth, and have enough bone for an implant will have the implant placed with standard infection-control measures (antiseptic mouth rinse, a surgical guide, and ibuprofen for relieving the pain) but no preventive antibiotics. Antibiotics will be given only if an infection develops. Participants will be seen 2 days, 7 days, 14 days, 1 month and 3 months after surgery. The main outcome is early implant failure, meaning the implant is lost before the replacement tooth is fitted. We will also record infection, pain, painkiller use, and gum health around the implant. The study will enroll 39 participants at the dental specialty clinic of the University of Medicine and Pharmacy at Ho Chi Minh City.

实验性的:Single Implant Placement Without Antibiotic Prophylaxis

Adults with one missing posterior tooth in a straightforward case receive a single dental implant placed with a tooth-supported surgical guide. No systemic antibiotic is given before or after surgery. Standardised care: ibuprofen 400 mg 1 hour before surgery; chlorhexidine 0.12 to 0.2% mouthrinse for 60 seconds; extraoral povidone-iodine 10% antisepsis. After surgery: ibuprofen 400 mg (9 tablets, up to three times daily, stopped when pain resolves) and gentle chlorhexidine 0.12% rinse on day 1. Systemic antibiotics (amoxicillin/clavulanate 1 g twice daily) are used only as rescue treatment if infection is diagnosed. Follow-up at day 2, day 7, day 14, 1 month and 3 months.

Single dental implant placement with standardised perioperative care (ibuprofen, chlorhexidine mouthrinse, povidone-iodine antisepsis, surgical guide) and no systemic antibiotic prophylaxis. Antibiotics are used only as rescue treatment for diagnosed infection.
