Background and objectives: Orthognathic surgery aims to correct dentofacial deformities and improve both function and facial esthetics. This study assessed long-term patient satisfaction and complication rates following bimaxillary orthognathic surgery, using a customized questionnaire to evaluate esthetic, functional, and psychosocial outcomes. Materials and methods: A total of 126 patients who underwent bimaxillary surgery for Class II or III dentofacial deformities were included in this retrospective cohort study with prospectively collected data and evaluated after a minimum follow-up of 3 years. Surgical procedures included Le Fort I osteotomy, bilateral sagittal split osteotomy, multisegmental osteotomies, genioplasty, and SARPE, with all cases planned and managed by an interdisciplinary team. Patient satisfaction was assessed using a 20-item individualized questionnaire based on validated tools (OQLQ, DAS-59, OHIP-14, VAS). Results: High levels of long-term satisfaction were reported, particularly in smile appearance and self-confidence. Smile-specific satisfaction remained stable regardless of skeletal class, gender, or complications. Postoperative complications occurred in 11.1% of patients and represented the main observed factor significantly associated with reduced overall satisfaction (p < 0.001). The most frequent complications included mandibular plate infection (n = 5), mandibular osteoperiostitis (n = 4), plate detachment (n = 2), plate fracture (n = 1), pseudoarthrosis (n = 1), and malunion with vicious callus (n = 1). All were successfully managed without long-term sequelae. Conclusions: Orthognathic surgery provides consistent long-term esthetic and psychosocial benefits. Individualized planning, interdisciplinary management, and the use of a customized satisfaction questionnaire may have contributed to the favorable patient-reported outcomes observed. These findings support the role of orthognathic surgery in enhancing quality of life beyond skeletal correction.

Background/Objectives: Anterior dental trauma in adolescents presents complex restorative challenges due to ongoing craniofacial development and high aesthetic expectations. This study evaluated the long-term clinical performance of feldspathic ceramic veneers and lithium disilicate crowns used in the anterior region following dental trauma in adolescents. Methods: A total of 209 restorations were placed in 85 adolescents (50 females, 35 males), aged 11.1–17.9 years (mean age: 15.1 years). Of these, 144 were lithium disilicate crowns, and 65 were feldspathic ceramic veneers. All restorations were fabricated using minimally invasive protocols and followed up for periods ranging from 3 to 60 months. Outcomes were assessed based on standardized clinical criteria for success and failure. Results: Lithium disilicate crowns exhibited superior long-term performance, with the majority of failures occurring in feldspathic veneers (p < 0.001), primarily due to chipping or structural fracture. Age and gender had no statistically significant influence on failure rates. Conclusions: Both feldspathic and lithium disilicate ceramic restorations represent viable treatment options for anterior dental trauma in adolescents. However, lithium disilicate demonstrates greater mechanical reliability, particularly in teeth with significant hard tissue loss. These results support the use of durable ceramic materials in adolescent restorative protocols involving dental trauma.

Background/Objectives: The stability of the gingival margin after crown lengthening is a key determinant of esthetic success in anterior rehabilitation. Digital workflows have been proposed to improve surgical precision, but their long-term impact on marginal stability remains insufficiently substantiated. Methods: A total of 87 patients (622 maxillary anterior and premolar teeth) who underwent esthetic crown lengthening were retrospectively evaluated. Patients were allocated to either a digitally guided workflow (G1, n = 62) or a freehand approach (G2, n = 25). Gingival margin stability was assessed using standardized intraoral photography and calibrated digital measurements at baseline, 1–2 months, and 12 months. Recurrence, periodontal parameters, complications, and patient satisfaction (VAS) were recorded. Mixed-effects models accounted for the clustering of teeth within patients. Results: Both workflows achieved predictable crown lengthening outcomes. At 12 months, median gingival margin recurrence was significantly lower in the guided group (G1: 0.14 mm [IQR 0.10–0.19]) compared with the freehand group (G2: 0.27 mm [IQR 0.20–0.34]) (p < 0.001). Secondary surgical revision was required in 1.6% of G1 patients versus 16.0% of G2 patients (p < 0.001). Patient satisfaction was high overall but greater in G1 (mean VAS 9.65 ± 0.52) than in G2 (8.96 ± 0.73). No major biological complications occurred. Conclusions: Digitally guided crown lengthening resulted in improved gingival margin stability and reduced the need for secondary correction compared with the freehand approach. Precise control of the bone crest position relative to the planned gingival margin is critical for long-term esthetic success.
