With the increasing life expectancy and improved quality of life, the conventional prosthodontic removable treatment modalities are being replaced with implant retained fixed prostheses. A full-arch conventional rehabilitation of edentulous ridges requires six to ten dental implants. However, some patients demand fixed implant-supported prostheses inspite of medical conditions and economic concerns. Also in completely edentulous cases, the insufficient bone morphology directs the treatment plan towards alternatives such as cantilever prostheses, short implants or ridge augmentation procedures. These clinical conditions have brought in a quantum shift in treatment planning towards the 'all on 4 protocol' providing immediately loaded fixed prosthesis supported by 4 implants thereby providing optimum and immediate restoration of function and esthetics.

Keloids are characterized by excessive growth of fibrous tissue resulting from abnormal wound-healing processes. They may lead to functional impairments, aesthetic deformities, pruritus, and a decreased quality of life. Various therapies, including intralesional corticosteroid injections, cryotherapy, laser therapy, surgical excision, and radiotherapy, have been used to manage keloids, but the recurrence rates remain high.

Background: The excision of oropharyngeal carcinoma of more than 50% of the soft palate followed by static reconstruction may result in functional deficits, including velopharyngeal insufficiency, swallowing, and speech difficulties. We describe a functional soft palate reconstruction technique aimed at restoring aeromechanical and acoustic functions, enabling swallowing without nasal regurgitation and speech with low nasalance.
Material And Methods: We developed a new operative technique, using muscle transfer and a free flap to create a dynamic reconstruction.

Successful rhinoplasty relies on a deep understanding of nasal anatomy and precise nasal tip control for lasting functional and aesthetic outcomes. Structural grafts, like septal extension grafts, are instrumental in maintaining tip position and projection with minimal long-term changes. This article details a systematic technique to harvest septal cartilage that maximizes graft material and allows for effective septal deviation correction.

Introduction: Soft-tissue sarcomas arising in the thigh may require total or subtotal compartmentectomy, with subsequent need for functional reconstruction with free functional muscle transfer (FFMT). We present our series, describing a new approach with chimeric propeller antero-lateral thigh-vastus lateralis (ALT-VL) free flap, which allows for independent muscle inset and soft tissue defect resurfacing.
Patient And Methods: A retrospective review of a prospectively maintained database was performed, analyzing all patients referred to Fondazione Policlinico Universitario Campus Bio-Medico, Rome, Italy, between 2018 and 2023 for soft-tissue sarcomas of the thigh requiring wide excision and reconstruction with functional ALT-VL.

Free vascularized partial great toe is a composite tissue consisting of the osteo-onycho-cutaneous component with neurovascular pedicle and is used for reconstructing amputated fingers at different levels. The half-big-toe nail flap represents that while it provides a good match and functional results; it also conserves the donor foot by having all five toes intact. The aesthetic and functional aspects of the amputated thumbs and fingers can be worked upon and significantly improved.
