Special Issue Information

Dear Colleagues,

Orthodontics and maxillofacial surgery are distinct yet interconnected specialties within the realm of dentistry. Orthodontics focuses on the diagnosis, prevention, and treatment of dental and facial irregularities, primarily through the use of braces, aligners, and other corrective devices. On the other hand, maxillofacial surgery involves surgical interventions to address complex craniofacial conditions, corrective jaw surgeries, and other related procedures.

The integration of these two disciplines offers a comprehensive approach to correcting diverse skeletal and dental discrepancies, functional impairments, and aesthetic concerns. The collaboration between orthodontists and maxillofacial surgeons is crucial for planning and executing interdisciplinary treatments that yield harmonious facial proportions, improved dental occlusion, enhanced oral function, and enhanced aesthetic outcomes.

This Special Issue aims to provide a platform for researchers, practitioners, and educators to share the latest advancements, clinical experiences, and scientific insights in the field of orthodontics and maxillofacial surgery. It encompasses a wide range of topics, including but not limited to:

  • Diagnosis and treatment planning: Evaluating the diagnostic tools, imaging techniques, and software applications that aid in accurate assessment and treatment planning for orthognathic surgeries and orthodontic treatments.
  • Surgical techniques and innovations: Exploring evolving surgical approaches, advancements in technology, and novel surgical techniques in maxillofacial surgery, with an emphasis on their impact on orthodontic treatment outcomes.
  • Orthodontic considerations in maxillofacial surgery: Discussing the role of orthodontics as a preparatory phase for surgery, including strategies for pre-surgical orthodontic treatment, the coordination of orthodontic and surgical treatment timelines, and the management of post-surgical orthodontic care.
  • Multidisciplinary collaboration: Highlighting successful collaborations between orthodontists, maxillofacial surgeons, periodontists, and other allied healthcare professionals to optimize patient care and achieve comprehensive treatment goals.

Evaluation of the Influence of Vestibular Surface Morphology Variability of Maxillary Incisors on Torque: Examination Using 3D Intraoral Scans

Proper torque is an important element of orthodontic treatment. There are many factors affecting effective torque expression, e.g., the interplay between an archwire and a bracket, the precision during bracket positioning, and the morphology of the crown vestibular surface (CrVS) of the tooth. Our study focused on the impact of the maxillary incisor CrVS morphology on the torque exerted by the archwire–bracket interplay. Three-dimensional models of 50 patients acquired through the use of an intraoral scanner were used to examine the four maxillary incisors. A total of 200 teeth were examined. The influence of the tooth crown shape on the bracket position and the related torque change was analyzed with Ortho Analyzer software 2015 (3Shape, Copenhagen, Denmark). All calculations were made for full size archwires. Central incisors showed less variability in their vestibular surfaces than lateral incisors. For the central incisors, the mean values of the additional palatal root torque ranged from 0.6° to 1.6°. For the laterals, the mean values ranged from 1.4° of additional vestibular root torque to 3.5° of additional palatal root torque. The results showed essential morphological differentiation of the CrVS of the maxillary incisors. Therefore, when the bracket is positioned, the individual variation in the tooth surface should be considered and evaluated. Full article

This systematic review aims to determine the impact of temporomandibular joint (TMJ) replacement on health-related quality of life. The review was reported following the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) guidelines. An electronic search using the Bielefeld Academic Search Engine was performed to identify primary studies reported in English and published up until November 2023. Ten reports fulfilled the inclusion criteria and were assessed according to the Critical Appraisal Skills Programme (CASP): Qualitative Studies Checklist. The overall research value of the studies ranged from high (dominant) to moderate. The synthesis of the results concerning TMJ replacement in severe degenerative disease showed an improvement in (1) quality of life, (2) pain intensity, (3) mastication efficiency, and (4) mandibular mobility. One study presented favorable outcomes for patients suffering from ankylosis. Full article

The swift integration of ‘Gummetal’ into the orthodontic armamentarium can be attributed to its distinct advantages as an entirely new Ti-Nb-based beta titanium alloy. Developed by Toyota Central R&D Labs and publicly revealed in April 2003, this innovative material is rapidly reshaping orthodontic practices. Its sui generis properties allow its use as a potential substitute for the Multi-Loop Edgewise Archwire (MEAW) method. Three-dimensional orthodontic movement using this new alloy could eliminate the disadvantages of the MEAW method, such as its technical complexity and patient discomfort. In our comprehensive review of the current literature, we examined relevant publications sourced from the PUBMED database and explored one seminal work on Gummetal from the journal literature. Characteristic properties of Gummetal, such as its exceptional flexibility, superelasticity, and malleability (approximately 10 times greater than conventional metals), enable seamless formation of bends without posing challenges, thereby allowing precise control over orthodontic force application. Also worthy of mention are Gummetal’s biocompatibility and non-toxic properties, along with its low coefficient of friction. The wire seems to be a relatively easy way to achieve good occlusion. Its usage does not require extensive experience in terms of manual skill, and it is not time consuming. Diligent usage of any prescribed plastics by the patient is crucial to prevent complications and ensure successful orthodontic outcomes. Full article
