Effect of maxillary molars distalization using clear aligners and fixed orthodontic appliances on the positional and dimensional temporomandibular joint parameters: a three-dimensional comparative study.

Objective: The use of clear aligners (CAs) for orthodontic treatment has substantially increased in recent decades. However, limited empirical evidence exists regarding their potential effects on the temporomandibular joint (TMJ). The aim of this study was to assess the effect of maxillary molar distalization on the positional and dimensional TMJ parameters between CAs and conventional fixed orthodontic appliances (FAs) in skeletal class II malocclusion.

Correlation between the three-dimensional hyoid bone parameters and pharyngeal airway dimensions in different sagittal and vertical malocclusions.

Objective: This study aimed to explore the relationship between three-dimensional (3D) measurements of the hyoid bone (HB) and pharyngeal airway space (PAS) in relation to sagittal and vertical malocclusion.

Methods: A total of 368 cone-beam computed tomography (CBCT) scans were classified into three skeletal groups (Class I, II, and III) and subdivided by vertical growth patterns (hypodivergent, normodivergent, and hyperdivergent). PAS dimensions, including nasopharyngeal, oropharyngeal, hypopharyngeal, and total airway spaces, were measured in surface area, volume, minimum constricted area (MCA), length, and width, HB position and dimension were analyzed in 3D using InVivo 6.

Patient-reported outcomes after oral cancer reconstructions with radial and ulnar forearm-free flaps.

Objectives: This study aimed to evaluate patient-reported quality of life and incidence of decision regret in patients undergoing radial (RFFF) and ulnar forearm-free flaps (UFFF) reconstruction.

Materials And Methods: Patients undergoing either RFFF or UFFF were assessed with the University of Washington Quality of Life (UW-QOL) and Oral Health Impact Profile (OHIP-14) questionnaires, and the Decision Regret Scale (DRS), both before and at least 12 months post-reconstruction.

Results: In total, 40 RFFF and 40 UFFF were included.

Evaluation of enamel surface integrity after orthodontic bracket debonding: comparison of three different system.

Objective: This study aimed to evaluate enamel surface integrity and time consumed during residual cement removal after bracket debonding using different adhesive removal burs with and without a dental loupe.

Material And Methods: Sixty human-extracted premolars were collected, cleaned, mounted, and prepared for orthodontic bracket bonding. Teeth were randomly divided into three main groups (n = 20) based on the adhesive removal method: tungsten carbide system (TC), sof-lex discs system (SD), and diamond system (DB) groups.

Evaluation of maxillary sinus changes following molar distalization using clear aligners: A three-dimensional study.

Objective: To evaluate the impact of molar distalization with clear aligners (CAs) on maxillary sinus parameters and its proximity to the root apices of maxillary molars using Cone Beam Computed Tomography (CBCT).

Methods: The study involved pre- and post-treatment CBCT images of 27 adult patients. MIMICS 21.

Impact of molar teeth distalization by clear aligners on maxillary alveolar bone thickness and root resorption: a three‑dimensional study.

Objective: This study aimed to evaluate the impact of molar teeth distalization movement by clear aligners on changes in the alveolar bone thickness and orthodontically induced inflammatory root resorption (OIIRR) in maxillary molars using conebeam computed tomography (CBCT).

Materials And Methods: Three-dimensional CBCT scans of 35 adult patients (one hundred forty maxillary molars) with pre-designed selection criteria and a mean age of 24.4 ± 7.

Radial and Ulnar Forearm Free Flaps: A Critical Comparison of Donor-Site Morbidity and Its Impact on Quality of Life.

Background: A poor evidence basis exists regarding directly comparing objective and subjective donor-site morbidity associated with the forearm flap. The authors evaluated the postoperative donor-site complications and quality-of-life outcomes between the radial forearm free flap (RFFF) and the ulnar forearm free flap (UFFF).

Methods: All patients undergoing RFFF or UFFF harvest were included.

Alveolar bone changes following bi-maxillary vertical molars' movements using clear aligners.

Objective: This study aimed to assess the alveolar bone changes following maxillary and mandibular molars' intrusion and extrusion movements using Clear Aligners using Cone-Beam Computed Tomography (CBCT).

Materials And Methods: This is a retrospective clinical study in which 24 adult patients with pre-designed selection criteria and a mean age of 31.1 + 9.

Lower lip reconstruction using McGregor fan technique with or without depressor anguli oris chimeric flap. Is there a difference in function and aesthetic outcomes?

Background: Lower lip reconstruction aims to maintain facial subunit function and aesthetics. We present a minor modification of the McGregor flap technique, in which depressor anguli oris (DAO) muscle is separately elevated as a chimeric flap together to investigate the outcomes for reconstructing lower lip defects using various functional parameters.

Methods: The study included patients who underwent surgical repair of lower lip defects using a McGregor fan flap with or without DAO muscle chimeric flap between January 2018 and May 2021.

Influence of inflammation on bleeding and wound healing following surgical extraction of impacted lower third molars.

Objective: This study aimed to investigate the effect of inflammatory states following impacted lower third molar (ILTM) surgery regarding postoperative bleeding and wound healing.

Methods: The study included patients who underwent extraction of ILTMs associated with or without inflammatory conditions. Post-extraction bleeding and wound healing were assessed.

Proximity of upper central incisors to incisive canal among subjects with maxillary dentoalveolar protrusion in various facial growth patterns.

Objective: To investigate the position of the upper central incisor roots (U1) relative to the incisive canal (IC) among subjects with maxillary dentoalveolar protrusion in various facial growth patterns.
