Title: Immediate implant placement in the anterior maxilla: A step by step approach for esthetic predictability
Abstract:
Background: Immediate implant placement (IIP) in the anterior maxilla is increasingly performed to reduce treatment time and preserve peri-implant tissues. However, it remains a highly technique-sensitive procedure, where minor deviations may lead to esthetic complications such as gingival recession, soft tissue discoloration, or buccal bone resorption.
Objective: To define the biological, surgical, and prosthetic determinants required to achieve predictable esthetic outcomes in immediate implant placement in the esthetic zone.
Materials and Methods: This work is based on the clinical experience of the Department of Oral Implantology at the Central Military Hospital of Algiers, supported by clinical cases illustrating different scenarios. A step-by-step clinical protocol is proposed, integrating patient selection, periodontal phenotype assessment, and cone beam computed tomography (CBCT) analysis to evaluate buccal bone integrity and sagittal root position. Particular attention is given to atraumatic extraction, prosthetically driven implant positioning, and peri-implant tissue management.
Results: Clinical outcomes emphasize the importance of strict adherence to key principles. Preservation of the buccal bone plate through atraumatic extraction is mandatory. CBCT evaluation allows accurate assessment of bone morphology and facilitates implant positioning. Implants should be placed in a palatal position, approximately 3 mm apical to the gingival margin, to ensure a stable emergence profile. Primary stability is achieved through apical anchorage (3–5 mm beyond the socket apex), while avoiding excessive implant diameter. Management of the peri-implant gap is critical: defects exceeding 2 mm require guided bone regeneration, often combined with connective tissue grafting to enhance soft tissue thickness. Immediate provisionalization plays a key role in shaping peri-implant soft tissues and optimizing the Pink Esthetic Score.
Conclusion: Immediate implant placement in the esthetic zone can provide predictable and stable esthetic outcomes when guided by a structured step-by-step approach combining clinical and CBCT-based evaluation. Clinical cases demonstrate that appropriate case selection, precise three-dimensional implant positioning, and meticulous soft tissue management are essential. A clinical decision-making algorithm is proposed to reduce complications and improve long-term esthetic outcomes.
