Primary Stability and Peri-implant Outcomes of Short Implants in Post-extraction Single-tooth Sites
Primary Stability and Peri-implant Outcomes of Short Implants in Post-extraction Single-tooth Sites: a Randomized Controlled Trial.
University of Bari Aldo Moro
10 participants
Jan 10, 2025
INTERVENTIONAL
Conditions
Summary
The placement of short implants in post-extraction sockets is a valuable option when residual bone height is limited, minimizing morbidity and treatment time. The management of the peri-implant gap and soft tissues may influence primary stability, hard/soft tissue remodeling, and implant success.
Eligibility
Inclusion Criteria5
- Age ≥18 years.
- Single-tooth post-extraction sites requiring immediate implant placement in posterior regions (premolars/molars) or selected anterior sites.
- Planned short implant (≤7-8 mm length, 3.5-5.0 mm diameter).
- Adequate oral hygiene, no active periodontal disease.
- Written informed consent.
Exclusion Criteria6
- Heavy smoking (\>20 cigarettes/day).
- Uncontrolled diabetes or systemic conditions affecting bone healing.
- Current bisphosphonate/antiresorptive therapy.
- Immunosuppression, pregnancy.
- Poor oral hygiene or acute infection at site.
- Severe bone dehiscence preventing primary stability.

Interventions
Two widely used approaches include: 1. Socket grafting with a fully resorbable synthetic biomaterial (β-tricalcium phosphate + calcium sulfate). 2. Socket grafting with a xenograft and a custom Sealing Socket Abutment (SSA) with a concave emergence profile. No randomized controlled trials have yet compared these protocols with integrated outcomes including resonance frequency analysis, peri-implant health indices, radiographic bone level changes, and digital intraoral scanning (IOS)-based morphometric analysis.
