Abstract
The esthetic zone presents particular challenges in implantology due to its high esthetic demands and visibility during speech and smiling. This paper presents a clinical case of a 26-year-old female patient with an unsatisfactory esthetic outcome following the placement of a dental implant in the right lateral incisor region of the maxilla, despite successful osseointegration. Through a personalized surgical approach and a minimally invasive protocol, the implant was explanted, the alveolus preserved, tissues augmented, and reimplantation performed in an ideal position, resulting in excellent functional and esthetic outcomes.
The development of implantology has revolutionized the treatment of tooth loss—especially in the esthetic zone, encompassing the anterior maxillary teeth (incisors, canines, and premolars). These teeth are visible during speech and smiling, so their replacement necessitates not only function, but also optimal esthetics.
Implant placement in this region demands a meticulous approach, due to anatomical and esthetic challenges. These include the thin nature of the vestibular bone plate, the critical position of the implant in relation to the lip line and interdental papillae, and the patient-specific morphology of soft tissues—all factors that directly affect esthetic success.
Implant mistakes—such as improper implant placement, inadequate bone volume assessment, incorrect implant selection, or poorly timed placement—can lead to significant functional and esthetic consequences. These include gingival recession, loss of interdental papillae, exposure of the implant body, and disharmonious smile lines. Failures are not limited to implant loss; rather, they often reflect failure to achieve esthetically acceptable outcomes—issues that are much harder to correct than failures in non-esthetic zones.
Furthermore, corrective reconstructive interventions—such as soft and hard tissue augmentation, reimplantation, or advanced prosthetic techniques—require time, cost, and may fail to fully restore the esthetic result. This makes careful planning and precise execution—both surgically and prosthetically—absolutely essential.
Implant mistakes—especially those involving improper reconstruction of hard and soft tissues before or during implant placement—are critical to the achievement of natural, long-term outcomes. Techniques in this context include using autologous soft tissue grafts, resorbable membranes, particulate or block bone grafts (autologous/autoplastic), and socket preservation techniques. These play a key role in ensuring stable gingival contours and harmonious integration of restorations with adjacent dental structures.
In this manuscript, we will examine the most common esthetic-zone implant mistakes, their underlying causes, and the protocols for their correction—anchored by a concrete clinical case illustrating esthetic failure and subsequent surgical-prosthetic resolution.
