“…Moreover, the atlas is instrumental in supporting the head and facilitating motion and stability within the craniovertebral region, through its articulatory surfaces and connections to various ligaments and muscles ( Cattrysse et al, 2016 ). Multiple anatomical variations of the atlas have been described such as accessory transverse foramina, ponticulus posticus and alterations in the fusion of its arches ( Macrì et al, 2023 ; Ogut et al, 2023 ).…”

Objective and backgroundThis study focuses on the atlas, a pivotal component of the craniovertebral junction, bridging the cranium and spinal column. Notably, variations in its arches are documented globally, necessitating a thorough assessment and categorization due to their significant implications in clinical, diagnostic, functional, and therapeutic contexts. The primary objective is to ascertain the frequency of these anatomical deviations in the atlas arches among a Colombian cohort using cone-beam computed tomography (CBCT).MethodologyEmploying a descriptive, cross-sectional approach, this research scrutinizes the structural intricacies of the atlas arches in CBCT scans. Analytical parameters included sex distribution and the nature of anatomical deviations as per Currarino’s classification. Statistical analyses were conducted to identify significant differences, including descriptive statistics and Chi-square tests. A systematic review of the literature was conducted in order to enhance the current Currarino’s classification.ResultsThe study examined 839 CBCT images, with a nearly equal sex distribution (49.7% female, 50.3% male). Anatomical variations were identified in 26 instances (3%), displaying a higher incidence in females (X2 [(1, N = 839) = 4.0933, p = 0.0430]). The most prevalent variation was Type A (2.5%), followed by Type B (0.4%), and Type G (0.2%) without documenting any other variation. The systematic review yielded 7 studies. A novel classification system for these variations is proposed, considering global prevalence data in the cervical region.ConclusionThe study highlights a statistically significant predominance of Type A variations in the female subset. Given the critical nature of the craniovertebral junction and supporting evidence, it recommends an amendment to Currarino’s classification to better reflect these clinical observations. A thorough study of anatomical variations of the upper cervical spine is relevant as they can impact important functional aspects such as mobility as well as stability. Considering the intricate anatomy of this area and the pivotal function of the atlas, accurately categorizing the variations of its arches is crucial for clinical practice. This classification aids in diagnosis, surgical planning, preventing iatrogenic incidents, and designing rehabilitation strategies.

Purpose: The objective of this work is to know the frequency of PP in a subpopulation of the city of Viña del Mar, Chile. What is the frequency of PP in cone beam tomography (CBCT)? Methods: This was a descriptive observational study of 722 CBCT scans. The presence or absence of PP was analyzed, and the Cederberg and Stubbs classification was used to determine the corresponding degree of ossification. Statistical analysis was performed to establish the relationship with age and gender using the Chi-square test. This study was approved by the Scientific and Ethics Committee of the Faculty of Dentistry, Andrés Bello University. Results: The frequency of PP was of 48.07%, with bilateral PP being more common (61.96%). In terms of laterality and degree of ossification, grade 2 of ossification predominated on both sides (right: 17.87%, left: 17.72%). A slight predominance of PP was observed in males (52.3%) compared to females (45.73%), but this was not statistically significant (p > 0.05). With respect to the frequency of PP and age range, it was observed in 50.75% of images of individuals over 41 years of age, 47.31% in those under 20 years of age, and 43.66% in those between 21 and 40 years of age, but these differences were not statistically significant (p > 0.05). Conclusion: The presence of PP is common in the population and is not associated with age or gender.

Scientific studies have shown that dysfunctional problems associated with dysmorphisms are the base of malocclusion. The position of the mouth and the head is a component of the general postural arrangement, so any head misalignment creates disharmonies and tensions among the neck muscles. Elastodontics is a treatment based on the use of removable elastomeric devices. These functional appliances are made of elastomeric material, acting tridimensionally on a neuromuscular system with orthopaedic and dental effects. Bioactivators have a vestibular and lingual flange with a free central area that permits them to position teeth without constraints. The flanges are linked by an occlusal plane that maintains the two skeletal bases and teeth in first-class normocclusion with propulsive and retropulsive effects on the maxilla and mandible. Elastomeric devices are generally well tolerated by patients requiring simple collaboration and management. This review aim is to describe the indications and limits of orthodontic therapy with elastomeric devices to provide an overview of elastodontics.
