Primary Stability and Peri-implant Outcomes of Short Implants in Post-extraction Single-tooth Sites

University of Bari Aldo Moro10 enrolled

Overview

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.

Interventions

Insertion of implants in post-extraction toothPROCEDURE

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.

Inclusion Criteria: * 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 Criteria: * 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.
