The field of orthodontics strives to achieve an aesthetic, healthy, and stable occlusion. However, traditional practices often assess occlusion in maximum intercuspidation without adequately considering the biomechanics of the temporomandibular joint (TMJ), which can lead to overlooking critical occlusal factors. This perspective paper revisits the debate on the role of occlusion in temporomandibular disorders (TMD) and evaluates the efficacy of current treatment approaches, emphasizing the limitations of conventional methods and the lack of evidence supporting joint-oriented orthodontics. By integrating jaw tracking systems and digital workflows, a comprehensive evaluation of dynamic and static occlusion with realistic mandibular movement allows for a more individualized treatment approach to ensure optimal treatment outcomes.

This comprehensive review investigates the treatment of vertical maxillary excess (VME) with and without anterior open bite (AOB) in seven unique case studies. These cases illustrate the implementation of advanced orthodontic techniques, such as miniscrew-assisted intrusion of the maxillary and mandibular arches. The multifaceted nature of AOB must be considered, highlighting the need for clear diagnostic criteria and an understanding of the long-term impacts of treatment strategies. The main goal of treatment is to reduce the vertical dimension of the maxillomandibular complex. A single miniscrew in the midpalatal region for the maxillary arch and two miniscrews in the buccal areas of the mandibular arch can be applied for the effective intrusion of the posterior teeth. The review then delves into the specific challenges and treatment modalities for managing VME without AOB, stressing the critical role of individualized intervention plans. Each case study demonstrates a different aspect of the treatment approach: from differential intrusion of molars to address esthetic concerns and functional issues to comprehensive strategies involving the intrusion of entire dental arches to correct severe malocclusions. The outcomes emphasize the importance of controlled orthodontic mechanics in achieving and maintaining optimal posttreatment stability. This review underscores the effectiveness of these treatment strategies in significantly improving facial profiles and dental function while highlighting the adjunctive use of myofunctional therapy and other retention techniques to prevent relapse. Collectively, these cases provide valuable insights into the tailored treatment of complex orthodontic conditions, offering guidance on achieving long-term success in clinical practice.

Open bite is a multifactorial problem, which is a challenging type of malocclusion for the orthodontist to treat. A careful and detailed diagnosis is important to ensure the correct treatment approach. With the use of temporary skeletal anchorage devices (TSADs), it is now possible in most cases to treat these malocclusions without surgical intervention. Several etiological factors are involved in the development of this malocclusion, including the patient's facial growth pattern, persistent sucking habits, tongue dysfunction, and mouth breathing due to compromised airways. These factors should always be identified early in a patient's life. Treatment strategies have included habit control, tongue crib, and correction of any airway problems, while in the more severe open bite patients, orthognathic surgery was necessary to correct the problem. Now, it can be treated by the intrusion of the posterior teeth using TSADs. This article presents one type of open bite resulting from condylar degeneration. In the past, this problem could have only been corrected with orthognathic surgery. Here, we demonstrate the result of an acquired open bite treated by intruding the posterior teeth with TSADs. In addition, we provide guidelines for selecting those cases that lend themselves to treatment with TSADs and those where combined orthodontic and orthognathic surgical correction is still needed.

Distraction osteogenesis can be described as a procedure that is based on the principles of physiologic remodeling and indirect fracture healing. In dentoalveolar level, conventional appliances may present some difficulties such as the need for multiple stages of DO to achieve a good occlusion due to distraction on a straight vector; incompetency to reduce the oronasal fistula in cleft patients; and the difficulty in achieving complete hard and soft tissue reconstruction, especially in cases with large alveolar defects.
