introduction

introduction

The management of anterior aesthetic edentulism presents a significant challenge due to the complexity of preserving and restoring hard and soft tissue around implant-supported prostheses. Achieving optimal aesthetic and functional outcomes requires meticulous surgical and prosthetic protocols to replicate the natural emergence profile and gingival architecture.

In this case series, we present 3 superimposed single-implant anterior clinical cases involving patients requiring central incisor restoration following extraction, with the dual aims of aesthetic prosthetic rehabilitation and harmonious integration surrounding tissues. A standardized surgical-prosthetic workflow was employed across all cases to ensure consistency in clinical outcomes.

Central to this approach was the utilization of the iPhysio® coded abutment, an innovative solution offering several biomechanical and biological advantages:

  • Emergence Profile Mimicry
    The abutment’s design closely replicates the natural tooth emergence, facilitating optimal peri-implant soft tissue contouring.
  • Enhanced Biocompatibility
    A zirconium-coated surface ensures superior tissue compatibility, promoting passive osseointegration and dynamic gingival adaptation.
  • Multifunctionality
    The abutment serves as a healing abutment, scan body, and interim prosthetic support, considerably simplifying the restorative workflow.
  • Seamless Transition
    The ability to retain the abutment from implant placement to final prosthesis delivery ensures biological continuity, particularly when paired with a zirconia crown, maintaining physicochemical synergy between the abutment and the prosthetic intra-gingival margin.

This case series highlights the clinical rationale and procedural benefits of the iPhysio® abutment, even in challenging anterior implant cases, highlighting its role in enhancing aesthetic predictability and long-term peri-implant tissue stability.

Tooth autotransplantation is the surgical repositioning of a tooth from one site to another within the same individual. When properly indicated, it represents a biological and conservative alternative to prosthetic replacement or implant therapy, particularly in growing patients where the other therapies may be contraindicated due to ongoing skeletal growth.

Modern implant dentistry increasingly relies on digital technologies to enhance diagnostic accuracy, treatment predictability, and workflow efficiency. Among these technologies, artificial intelligence (AI) integrated into advanced imaging systems is rapidly transforming the clinician’s ability to detect pathologies, evaluate anatomical structures, and plan surgical procedures with greater confidence.

Traditional silicone-key direct composite restorations suffer from variable thickness, internal voids, imprecise trimming and high labor cost. Pressed composite integrates facially-guided Digital Smile Design, dual-step 3D-printed IBT-Flex guides, and a volumetric “PRESS” dispenser filled with high-fill composite. In a two-visit restorative session following clear-aligner therapy and guided crown lengthening, this workflow achieved exact replication of the planned anatomy, texture, form, and function. The 18-month follow-up findings show stable margins, minimal wear and high patient satisfaction.

Overall function remained stable but was suboptimal.

Digital dentistry has transformed restorative and esthetic treatments. Technologies such as intraoral scanning, digital smile design, and chairside manufacturing enable clinicians to deliver precise, minimally invasive, and efficient care. Notably, 3D printing allows the same-day fabrication of indirect restorations with excellent esthetic and mechanical properties.

Dr. Miloš Ljubičić

Digital dentistry has undergone rapid developments and changed the contemporary approach to patient treatment in many ways. New chairside digital workflow protocols, for example, enable dental practitioners to simplify previously multistep laboratory procedures, reducing treatment time and lowering the cost of the process. Chairside protocols enable clinicians to perform restorations in a single office visit, providing patients with a more comfortable and efficient experience.
