You may have heard from professors at some point in your academic or professional training that we should base our decisions in orthodontics on science/literature, right? For example, have you ever heard that if there is no scientific proof of the effectiveness of a certain orthodontic therapy for a particular problem, then it doesn’t work?

Over the years, orthodontics has been blessed with minds that not only challenge the conventional, but reshape paradigms to reflect a deeper and more compassionate understanding of the humanity behind the smile. Thirteen years ago, I had the distinct honor of prefacing a fruitful work by the authors interviewed here: the book “Orthológica”. This work has illuminated the path for countless professionals and students, bringing clarity and direction to a discipline that sometimes seemed...

INTRODUCTION: AThe advantage of using aligners to correct anterior open bite is the greater ease to intrude the posterior teeth, due to the plastic that surrounds the teeth. OBJECTIVE: The present article reports the clinical case of an adult patient with anterior open bite treated exclusively with Invisalign aligners. CASE REPORT: Closing the bite with aligners was performed by the combination of posterior teeth intrusion and anterior teeth extrusion, in addition to a counterclockwise...

INTRODUCTION: Dental anterior crossbite (AC) is a malocclusion characterized by an alteration in the relationship of anterior teeth, and early treatment of this problem is of fundamental importance. OBJECTIVE: To present two clinical cases of dental AC in the mixed dentition phase, treated with fixed orthodontic appliances using the 2 x 4 and 2 x 2 techniques. CONCLUSION: The cases demonstrated that the 2 x 4 and 2 x 2 techniques are versatile and highly efficient, indicated for the...

OBJECTIVE: This article explores the challenges of treating Class II malocclusion, focusing on the distal movement of upper molars, premolars, and canines using distalization appliances such as the Carriere type. METHODS: The mechanics of force application was examined, including traditional elastics, miniscrews, and the combination of techniques, to optimize treatment outcomes. CONCLUSIONS: The analysis highlighted the importance of understanding the system’s center of resistance and the...

INTRODUCTION: During odontogenesis, the union of two teeth may occur, which characterizes the extremely rare tooth anomaly called fusion. Dental anomalies have a hereditary or environmental origin, and raise malocclusion and aesthetic concerns. Therefore, the study of teeth abnormalities association and therapeutic or preventive approaches is essential in orthodontic clinical practice. OBJECTIVE: This article aims to describe the clinical case of a Class II patient with posterior crossbite,...

INTRODUCTION: Anterior open bite, a malocclusion characterized by a vertical gap between the anterior teeth during maximum intercuspation, can be treated with various approaches, including first molars extraction, orthognathic surgery, elimination of the etiological causes, and extrusion of anterior teeth and intrusion of posterior teeth. OBJECTIVES: This case report illustrates the use of a modified C-palatal plate (MCPP) and fixed appliances to treat anterior open bite in an adolescent...

INTRODUCTION: Several authors have investigated the possible influence of different variables on smile esthetics, such as: midline diastemas, dental and/or gingival asymmetries, amount of gingival exposure in a smile, central-to-lateral incisal step, and types of buccal corridors. However, the possible influence of the unilateral or bilateral absence of the upper first premolars has not yet been evaluated. The answer to this question is important because the extraction of these teeth is a...

OBJECTIVE: To define and suggest diagnostic criteria for occlusal trauma in the orthodontic context. METHODOLOGY AND RESULTS: To reflect on and recoverer concepts that are standardized in the relevant literature, and extrapolate them clinically. DISCUSSION AND CONCLUSIONS: 1) Occlusal trauma should be included in the list of differential diagnoses of apical periodontitis and dental trauma. 2) Periapical sclerosing osteitis in a tooth with pulp vitality and inflammatory apical external...

OBJECTIVE: The objective of this article is to report a clinical case of an adult patient with bilateral posterior crossbite (PCB), anterior crossbite (ACB), anteroinferior crowding, transverse skeletal deficiency of the maxilla, in addition to periodontal problems and gingival recession. CLINICAL CASE: The treatment was conducted with periodontal monitoring, and the orthodontic approach was carried out conventionally, consisting of expansion of the maxilla with crossed elastics and expanded...
