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.

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.

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.
