Immediate and Delayed Implant Placement Protocols: A Comparative Case-Based Perspective

Dental implants have become a predictable and widely accepted treatment modality for replacing missing teeth, offering functional and esthetic rehabilitation. Advancements in implant design and surgical protocols have enabled clinicians to adopt various placement and loading strategies that are tailored to individual clinical scenarios. The selection of an appropriate protocol is critical for optimizing the treatment outcomes. This report describes two clinical scenarios involving a 55-year-old female patient who required mandibular first molar replacements. In the first scenario, the tooth was extracted atraumatically, followed by immediate implant placement; loading was deferred until after a six-month healing period. In the second scenario, implant placement was postponed for six months post-extraction, after which immediate nonfunctional loading was carried out within 48 hours. Standardized surgical protocols were followed in both cases to ensure adequate primary stability and preservation of the surrounding tissues. Clinical and radiographic evaluations revealed successful osseointegration, stable peri-implant soft tissues, and minimal marginal bone loss using both approaches. No complications, such as infection, mobility, or peri-implant inflammation, were observed during follow-up. Within the limitations of this report, immediate implant placement with delayed loading and delayed implant placement with immediate nonfunctional loading demonstrated predictable and favorable outcomes when appropriate case selection and clinical protocols were followed.
