“…The results contrast with studies in which the curve of Spee showed a statistically significant relapse, with average of 0.84mm in patients with Class II malocclusion [11] and mean leveling of 1.60mm (63%) and average relapse of 0.26 mm (16%) [18]. The long-term stability of orthodontic treatment is a challenge for dentists because it is almost impossible to ensure absolute stability after treatment [21].…”

“…A flat curve is proposed as a way of overcorrection in orthodontic treatment since there is a natural tendency of deepening the curve over time, which can lead to an undesirable increase in overbite and posterior occlusal interferences [8,10]. Alterations due to orthodontic treatment may have undesirable recurrences after device removal, often almost returning to its original features [11]. One of the great challenges of orthodontics is to achieve long-term occlusion stability after orthodontic treatment.…”

Objective: To assess the long-term stability of leveling the curve of Spee after at least 8 years post-treatment in patients with mesocephalic pattern. Material and Methods: Measuring the depth of the curve of Spee in 10 mesocephalic patients at the following times: T0 (before the beginning of orthodontic treatment), T1 (at the end of orthodontic treatment) and T2 (at least 8 years after orthodontic treatment). These measures were compared using paired t-test (significance level of 5%). The curve depths were calculated from the measures of the distances between the lower buccal cusp of the posterior teeth of each side to a reference surface, which was supported by 3 points of the lower cast. Results: The mean curve of Spee depth at T0 was 1.86 mm, 0.50 mm at T1 and 0.53 mm at T2. The mean correction of the curve of Spee depth was 1.36 mm (73.11%) and the average relapse was 0.03 mm (2.2%). No statistically significant difference between T1 and T2 values in left or right sides was found. On the other hand, significant differences among T0 and T1 and T0 and T2 values were found. Conclusion:The results suggest that there was no significant depth relapse of the curve of Spee and also that leveling the curve is a stable procedure after 8 years after treatment in mesocephalic patients still using mandibular fixed retainer. The values found when comparing the depth in T0 and T1 showed that the curve of Spee was leveled during orthodontic treatment.

“…Most of the posterior ones are lost by caries, rarely by trauma [26][27][28]. To maintain the spaces of dental losses, the use of space-saving devices is indicated, as there is no loss of space, since the permanent tooth may take months to erupt [29][30][31][32]. In another study on the incidence of malocclusions, with 41 patients examined, 42 premature extractions of primary first molars and 71 premature extractions of primary second molars were found.…”

Introduction: In the aesthetics scenario, facial optimization is considered an essential outcome of orthognathic treatment (OT) due to its potential advantages in reducing the duration and cost of treatment, providing early aesthetic improvement, and increasing patient satisfaction. Objective: It presents a systematic review study listing the main optimizations of facial aesthetics through orthognathic surgery, to highlight the importance of this treatment for improving patients' comfort and quality of life. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from January to March 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 179 articles were found, 45 articles were evaluated in full and 39 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 15 studies with a high risk of bias and 31 studies that did not meet GRADE and AMSTAR-2. Most studies did not show homogeneity in their results, with X2=69.5%>50%. It was concluded space maintenance is one of the most important activities in the prevention of malocclusion. The maintenance of the lost space is of paramount importance to ensure normal eruption and development of the dentition. Aesthetic/functional rehabilitation is necessary until the eruption of permanent successor teeth occurs. A practical option to obtain this rehabilitation is through the installation of aesthetic or functional space maintainers. There are several requirements, such as maintaining the desired interproximal space, not interfering with the occlusion of the opposing teeth nor with the eruption of the permanent tooth, allowing sufficient mesiodistal space for the permanent tooth alignment to erupt, not inferring in phonetics and chewing and present a simple framework and be easily sanitized. Thus, the neuromuscular stability of the stomatognathic system may be impaired by the presence of deleterious habits.

Introduction: The temporomandibular joint (TMJ), being the only mobile joint in the skull, is one of the most complex structures to study, this joint allows rotation and translation movements, this is due to its double joint with the condyle and its condylar cavity. The term Temporomandibular Disorders (TMD) is used to describe TMJ diseases that may be related to the joint, musculature, ligaments, bone, tooth, and psychological aspects. Objective: It was to address the main considerations and clinical findings of temporomandibular disorders and the use of space maintainers through a concise systematic review. Methods: The present study followed a systematic review model, following the rules of systematic review – PRISMA. The search strategy was performed in the PubMed, Cochrane Library, Web of Science and Scopus, and Google Scholar databases. The quality of the studies was based on the GRADE instrument, and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: The total of 136 articles were found. A total of 76 articles were fully evaluated and 34 were included in this study. A total of 34 studies were excluded with a high risk of bias (studies with a small sample size). Also, 42 studies were excluded because they did not meet the GRADE. The results showed that the stomatognathic system (SS) is extremely important in the physiological interconnection with its constituent elements and the central nervous system. An interference can lead the masticatory muscles to adapt their function to protect the SS, leading the mandible to a position with different dental contacts, which can cause damage to the TMJ. These damages can generate parafunction or TMD. Space maintenance is one of the most important activities in the prevention of malocclusion. A practical option to obtain this rehabilitation is through the installation of aesthetic or functional space maintainers.
