Introduction: Facial aging is a multifactorial process characterized by skin laxity, volume loss, and collagen degradation. Calcium Hydroxyapatite (CaHA) is a versatile biostimulatory filler that can provide both structural support and collagen stimulation. This study evaluates a novel technique using CaHA with tailored dilutions for minimally invasive facial rejuvenation, focusing on key ligamentous structures.

Purpose: This study aimed to compare the dimensional and positional deviations of additively manufactured removable dies fabricated using two bio-based resins and one conventional dental cast resin, while also evaluating these outcomes over a 4-week period.
Materials And Methods: A right mandibular first molar preparation on a typodont was scanned to digitally design removable dies and hollow partial arch casts. Based on a priori power analysis, a total of 30 dies (n = 10) and three hollow casts (n = 1) were fabricated using additive manufacturing (AM) from three different dental cast resins: DentaMODEL (DM), FotoDent bio-based model (CB), and soy-based resin (SB).

Segmental mandibulectomy is a valid treatment for advanced medication-related osteonecrosis of the jaw (MRONJ), but subsequent reconstruction is challenging. Spontaneous bone regeneration (SBR) following resection is exceedingly rare, particularly in the elderly. We present the case of a 63-year-old woman with stage 3 MRONJ who underwent a 60 mm segmental mandibulectomy.

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.

Background: Postoperative complications significantly impact outcomes in head and neck free-flap reconstruction. The comprehensive complication index (CCI) offers a continuous measure of complication burden but is rarely applied in head and neck surgery compared to the Clavien-Dindo Classification (CDC).
Methods: This retrospective study analyzed 354 patients who underwent head and neck free-flap reconstruction.
