Immediate short implants to replace a single extracted tooth

Primary Stability and Peri-implant Outcomes of Short Implants in Post-extraction Single-tooth Sites: a Randomized Controlled Trial.

NA · University of Bari Aldo Moro · NCT07177521

This study will test whether placing short dental implants right after removing a single tooth in patients with limited bone provides solid support and healthy gum and bone healing.

What this trial studies

Participants who need a single-tooth replacement following extraction (primarily premolars and molars, and some selected anterior sites) will receive a short implant (about 7–8 mm or shorter) placed immediately into the extraction socket. The trial will focus on how the peri-implant gap and soft-tissue management affect primary implant stability and subsequent hard- and soft-tissue remodeling. Clinical measurements and radiographs will be used during follow-up visits to monitor stability, tissue changes, and implant survival. Patients with significant bone defects or contraindications to healing will be excluded to preserve primary stability and standardize results.

Who should consider this trial

Good fit: Adults (≥18) needing immediate single-tooth replacement in posterior sites or selected anterior sites, with good oral hygiene and a planned short implant (≤7–8 mm), are ideal candidates.

Not a fit: Patients who are heavy smokers (>20 cigarettes/day), have uncontrolled diabetes or conditions that impair bone healing, are on antiresorptive therapy, are immunosuppressed or pregnant, have poor oral hygiene or acute site infection, or have severe bone dehiscence are unlikely to benefit.

Why it matters

Potential benefit: If successful, this approach could offer a faster, less invasive option for replacing a single tooth when vertical bone height is limited.

How similar studies have performed: Previous clinical reports on immediate placement and on short implants have shown promising results in well-selected patients, though outcomes depend strongly on case selection and soft-tissue/bone management.
