Background: Three millimeter is considered as the minimum distance to obtain soft and bone tissue stability in case of adjacent implants. The possibility to preserve peri-implant bone level using a platform switching connection has questioned this concept.
Purpose: The study evaluates soft tissue maintenance and marginal bone stability around implants, placed at 2 or 3 mm of distance.
Materials And Methods: Thirty patients received two immediately loaded implants either at 2-mm (test) or at 3-mm (control) of distance in the premolar area. Soft tissue esthetics (papilla height and fill, keratinized tissue, recession) and radiographic peri-implant bone level changes were measured at 3, 6, and 12 months.
Results: No significant differences between the two groups were detected neither for all soft tissue esthetic outcomes nor for bone level modifications up to 12 months.
Conclusion: The results suggested that up to 12 months post-loading, both 2- and 3-mm inter-distance platform-switched implants in healed site, supported adequate esthetic outcomes and peri-implant bone stability.

Introduction: Complex soft tissue injuries in the facial area can arise from various causes. Surgeons face significant challenges when reconstructing these injuries, as they must select appropriate materials based on texture and color, while also considering their composition and properties. The anterolateral thigh (ALT) flap has emerged as a versatile option in clinical reconstructive surgery, offering many advantages over other free flaps.

The vitamin B complex, a group of water-soluble vitamins, is essential for various metabolic and cellular processes and critical for achieving optimal surgical outcomes in plastic and cosmetic procedures. This review examines the mechanistic contributions of this complex at the cellular level, including any roles in mitochondrial bioenergetics, redox balance, gene regulation, and cellular repair mechanisms. Niacinamide, as a precursor to NAD⁺, enhances mitochondrial efficiency and facilitates energy production, supporting tissue regeneration.

Titanium is widely used for dental implant abutments due to its mechanical strength, biocompatibility, and corrosion resistance; however, its gray coloration can compromise esthetic outcomes, particularly in patients with thin or translucent gingival biotypes. Anodization, a surface modification technique altering the titanium oxide layer, has been proposed to improve soft tissue aesthetics by producing abutments with warmer tones (eg, pink or gold) that harmonize with the surrounding gingiva. This systematic review aimed to evaluate the clinical and aesthetic outcomes of anodized titanium abutments compared to non-anodized titanium and other materials, with a focus on peri-implant soft tissue health and visual integration.

Functional reconstruction of large mandibular defects, especially in young patients, presents a significant clinical challenge. The ideal approach should not only restore skeletal contour but also address nerve deficits and facilitate final occlusal rehabilitation, all while minimizing morbidity. This report describes a comprehensive, multi-staged strategy for such a case.

Periorbital defects resulting from oncologic resections, trauma, or congenital malformations pose a complex reconstructive challenge, due to the need to simultaneously restore eyelid function and facial esthetics. We present the case of a male patient in his seventh decade of life with a right orbitomalar squamous cell carcinoma, who underwent a wide oncologic resection involving the upper and lower eyelids, as well as the malar and infraorbital regions. Reconstruction was performed using a radial free forearm flap from the left arm, including the palmaris longus tendon, which was strategically anchored to the medial canthus and orbital rim to provide dynamic eyelid support.
