Evaluation of the eruption of permanent teeth and their association with malocclusion

Early Diagnosis and Treatment of Mandibular Second Premolar Impaction: A Case Report

Odontogenesis, the process of tooth formation, is complex and susceptible to disruptions that can result in dental anomalies such as tooth impaction. The mandibular second premolar, though less commonly impacted than wisdom teeth, presents a unique challenge in pediatric dentistry due to its intricate etiology and the need for timely intervention. This case report aims to highlight the significance of early diagnosis and conservative management strategies in treating mandibular second premolar impaction. The case involves a pediatric patient with impacted mandibular second premolars. Initial treatment included the use of a lower removable appliance with an expansion screw to alleviate crowding, followed by a fixed space maintainer and a Haas rapid palatal expander. These interventions created the necessary space for the premolars to erupt. Self-ligating brackets were later applied, reducing friction and improving periodontal health. The patient underwent two CBCT examinations to monitor progress, which confirmed the successful eruption and alignment of the impacted premolars without the need for surgical exposure. This case underscores the effectiveness of early diagnosis and minimally invasive treatment in managing mandibular second premolar impaction. The tailored approach facilitated the natural eruption of the teeth, highlighting the importance of individualized treatment plans. Future research should focus on optimizing these conservative strategies to enhance patient outcomes in similar cases.

Abnormal tooth maturation associated with port wine stains

OBJECTIVE

This study aims to evaluate the potential impact of port wine stains on the development of permanent teeth in mixed dentition and provide insights for managing tooth abnormalities in patients with port wine stains.

MATERIALS AND METHODS

A retrospective analysis was conducted on 21 patients with mixed dentition and unilateral maxillary port wine stains. Two researchers concurrently utilized Nolla Analysis to assess the developmental stage of bilateral maxillary and permanent mandibular teeth based on panoramic radiographs. The cumulative developmental values of upper and lower permanent teeth on both sides were calculated, and a comparison was made between the developmental stages of the upper and lower jaws.

RESULTS

Port wine stains can influence the maturity of permanent upper teeth, within the unilateral maxillary port wine stains range, with an early developmental completion observed on the affected side compared to the unaffected side. While the developmental stages of the lower teeth on both sides showed similarities.

CONCLUSIONS

Port wine stains can accelerate the maturity of teeth on the affected side, leading to alterations in the order of tooth eruption and subsequent abnormal occlusion in children with mixed dentition. These findings provide a basis for developing appropriate management strategies for addressing tooth abnormalities in patients with port wine stains.

Myobrace versus twin block in the treatment of class II malocclusion in Children: A systematic review

Background

One of today's largest global problems is malocclusion. We must prevent this through the screening and early treatment of young children, because malocclusion treatment conducted during a child's growth and development stage either the primary or mixed dentition era yields the best outcomes. Functional appliances are usually used during initial orthodontic treatment, such as myobrace and twin block appliances. Myobraces come in various sizes. The size chosen depends on the treatment objectives, which may include correcting class II malocclusions. The twin block appliance is a functional device commonly employed to treat class II malocclusions.

Purpose

This investigation's main goal was to compare the efficacy of the myobrace and twin block appliances in class II malocclusion treatment to select a more appropriate pediatric dentistry device.

Results

A total of 5 articles were selected from 306 articles based on relevant keywords. All selected studies were conducted within the last 10 years.

Discussion

Myobrace and twin block appliances can address overjet issues and achieve significant overjet measurement reductions. This appliance promotes mandibular growth and enhances the facial profiles of individuals with class II malocclusions.

Conclusion

In order to treat individuals with class II malocclusions, the myobrace and the twin block both address skeletal and dentoalveolar discrepancies. But compared to the myobrace, the twin block appliance had more noteworthy outcomes.

Comparisons of Two Different Treatment Methods for Impacted Maxillary Canines: A Retrospective Study

Background: The impaction of the maxillary canine is a common occurrence, and orthodontists must be prepared to manage it. The purpose of this article is to present a study of the efficacy of a double-wire orthodontic appliance compared to a control group in the alignment of impacted maxillary canines in the dental arch. Methods: To diagnose an impacted maxillary canine, a panoramic radiograph was taken and a detailed analysis was performed by the same orthodontist. This article presents the results of 28 impacted maxillary canines with inclusion criteria of A2 (tooth angulation to the midline 16°-45°), V1 (vertical height of the tooth crown above the cementoenamel junction but less than half the length of the root of the maxillary lateral incisor), and O3 (medial position of the canine crown of more than half but less than the entire root width of the lateral incisor) positions in 21 patients (7 males and 14 females) with a mean age of 14.02 years (SD = 1.61) who were treated by the same orthodontist for impacted maxillary canines using a fixed double-wire orthodontic appliance. The analyzed data were compared with the control group (treated with a fixed orthodontic appliance and active ligature), which was matched for pretreatment age and the A2, V1, and O3 positions of the impacted maxillary canine. Results: With both methods, the impacted maxillary canines were aligned and guided into a correct position in the dental arch, but the mean active orthodontic traction of 31 ± 4.2 weeks in the SG was statistically significantly shorter (p < 0.05) in comparison to 37 ± 6.3 weeks in the CG, and the number of visits was statistically significantly (p < 0.05) fewer in the SG (5 ± 2) than in the CG (11 ± 5). Conclusions: The findings of this study are important to the field of orthodontics and show that the alignment of impacted maxillary canines with A2, V1, and O3 positions can be achieved with both methods, but with the double-wire appliance, the treatment time was shorter and the number of visits was statistically significantly fewer. The results of this study suggest that this approach may be more efficient and cost-effective compared to conventional methods.

Mini-Implant Insertion Using a Guide Manufactured with Computer-Aided Design and Computer-Aided Manufacturing in an Adolescent Patient Suffering from Tooth Eruption Disturbance

Due to dental diseases, anatomical restrictions, and mixed dentition, the reduction in the number of teeth and the displacement of tooth germs pose challenges in orthodontic treatment, limiting anchorage options. The presented case demonstrates an advanced treatment solution using digital CAD/CAM-technologies and medical imaging for the creation of a mini-implant template. A 12-year-old male patient experiencing delayed tooth eruption, multiple impacted germs, and maxillary constriction underwent intraoral scanning and CBCT. Utilizing coDiagnostiXTM Version 10.2 software, the acquired data were merged to determine the mini-implant placement and to design the template. The template was then manufactured through stereolithography using surgical-guide material. Mini-implants were inserted using the produced appliance, enabling safe insertion by avoiding vital structures. Surgically exposed displaced teeth were aligned using a Hyrax screw appliance anchored on the mini-implants for rapid palatal expansion (RPE) and subsequently used as fixed orthodontics to align impacted teeth. The screw was activated daily for 10 weeks, resulting in a 7 mm posterior and 5 mm anterior maxillary transversal increase. Skeletal anchorage facilitated simultaneous RPE and tooth alignment, ensuring accuracy, patient safety, and appliance stability. The presented case shows a scenario in which computer-aided navigation for mini-implant positioning can enhance precision and versatility in challenging anatomical cases.
