Timely Treatment

There is no universal agreement as to which type of orthodontic or orthopedic treatment deserves early intervention. In addition, there is a need for more information as to which treatments are the most effective and less costly if they are initiated timely in the mixed dentition. Early timely treatment may benefit young patients with a maxillary transverse deficiency with or without a posterior crossbite that requires maxillary expansion. It may also be indicated in children with anteroposterior jaw discrepancy that requires chin cup or maxillary protraction. In this paper, the authors will focus on early maxillary expansion to facilitate the eruption of maxillary laterals. In specific, the authors will present a contemporary protocol using a bonded maxillary expander as anchorage for treatment of unerupted maxillary laterals. The use of this protocol was illustrated with two case reports to enable clinicians to routinely achieve a beautiful smile on a young patient by timely alignment of the maxillary incisors.

Some adult cleft palate patients show severe maxillary transverse contraction and posterior crossbite. This case report demonstrates successful surgical-orthodontic treatment of such a patient. Surgically assisted rapid maxillary expansion (SA-RME) was completed prior to comprehensive orthodontic treatment. The osteotomy was performed on both the buccal and lingual aspects of the posterior maxillary alveolus. A Hyrax-type maxillary-expansion appliance was used, and the screw (0.2 mm, one quarter turn) was turned two or three times per day. Comprehensive orthodontic treatment was initiated after extraction of the mandibular first premolars and four third molars. The maxillary lateral incisors were also extracted after active orthodontic treatment. The amount of expansion achieved using SA-RME was greater at the posterior than at the anterior maxilla. Midpalatal suture opening occurred. After orthodontic treatment, occlusal stability was satisfactory. This case demonstrates the effectiveness of SA-RME in adult cleft palate patients with severe posterior crossbite.

Objective: To understand the actual condition of orthodontic treatment in team care for patients with syndromic craniosynostosis (SCS) in Japan. Design: A nationwide collaborative survey. Setting: Twenty-four orthodontic clinics in Japan. Patients: A total of 246 patients with SCS. Main Outcome Measure: Treatment history was examined based on orthodontic records using common survey sheets. Results: Most patients first visited the orthodontic clinic in the deciduous or mixed dentition phase. Midface advancement was performed without visiting the orthodontic clinic in about a quarter of the patients, and more than a half of the patients underwent “surgery-first” midface advancement. First-phase orthodontic treatment was carried out in about a half of the patients, and maxillary expansion and protraction were performed. Tooth extraction was required in about two-thirds of patients, and the extraction of maxillary teeth was required in most patients. Tooth abnormalities were found in 37.8% of patients, and abnormalities of maxillary molars were frequently (58.3%) found in patients who had undergone midface surgery below the age of 6 years. Conclusions: Many patients underwent “surgery-first” midface advancement, and visiting the orthodontic clinic at least before advancement was considered desirable. First-phase orthodontic treatment should be performed considering the burden of care. Midface advancement below the age of 6 years had a high risk of injury to the maxillary molars. This survey is considered useful for improving orthodontic treatment in team care of patients with SCS.

Objective: To determine morphological and functional effects on masticatory system of early treatment of functional posterior crossbite in young children. Study design: 23 children were divided into two groups:deciduous (DecG, n=11) and early mixed dentition (MixG, n=12), which received slow maxillary expansion. Maximal bite force, ultrasonographic masticatory muscle thickness and facial asymmetry were evaluated in three stages: before the start of treatment (s1), after three months of retention (s2), and after three months of observation (s3). The results were analyzed by Mann-Whitney U-test, correlation test, repeated measures ANOVA and backward stepwise multiple regression. Results. Bite force and temporalis thickness increased from s1 to s2 and s3 in both groups (p<0.05). Body mass index (BMI) increased significantly from s1 to s3 only in the MixG, but the masseter thickness did not differ among the stages. The correlation between the angle of the eye and the angle of the mouth in relation to the mid-sagital plane increased from s1 to s3. Masticatory muscle thickness contributed significantly to bite force magnitude in all stages, whereas age and BMI showed no significant contribution to its variation. Conclusion: Bite force and temporalis muscle thickness increased significantly in children after early treatment of functional crossbite.

INTRODUCTION: This retrospective cephalometric study analyzed the influence of intentional ankylosis of deciduous canines in patients with Class III malocclusion and anterior crossbite, in the deciduous and early mixed dentition stages, treated by orthopedic maxillary expansion followed by maxillary protraction. METHODS: Lateral cephalograms of 40 patients were used, divided in 2 groups paired for age and gender. The Ankylosis Group was composed of 20 patients (10 boys and 10 girls) treated with induced ankylosis and presenting initial and final mean ages of 7 years 4 months and 8 years 3 months, respectively, with a mean period of maxillary protraction of 11 months. The Control Group comprised 20 patients (10 boys and 10 girls) treated without induced ankylosis, with initial and final mean ages of 7 years 8 months and 8 years 7 months, respectively, with a mean period of maxillary protraction of 11 months. Two-way analysis of variance and covariance analysis were applied to compare the initial and final cephalometric variables and the treatment changes between groups. RESULTS: According to the results, the variables evidencing the significant treatment changes between groups confirmed that the intentional ankylosis enhanced the sagittal response of the apical bases (Pg-NPerp) and increased the facial convexity angles (NAP and ANB). CONCLUSIONS: The protocol involving intentional ankylosis of deciduous canines enhanced the sagittal response of the apical bases.

ABSTRACT OBJECTIVE: The aim of this systematic review was to evaluate the duration of the retention period in growing patients undergoing maxillary expansion and its relation with posterior crossbite stability. METHODS: Search strategies were executed for electronic databases Cochrane Library, Web of Science, PubMed and Scopus, which were completed on January 15, 2016. The inclusion criteria included randomized, prospective or retrospective controlled trials in growing subjects with posterior crossbite; treated with maxillary expanders; retention phase after expansion; post-retention phase of at least 6 months. The exclusion criteria were anterior crossbite, craniofacial anomalies, surgery or another orthodontic intervention; case reports; author’s opinions articles, thesis, literature reviews and systematic reviews. The risk of bias of selected articles was assessed with Cochrane risk of bias tool for RCTs and Downs and Black checklist for non-RCTs. RESULTS: A total of 156 titles/abstracts was retrieved, 44 full-texts were examined, and 6 articles were selected and assessed for their methodological quality. The retention period after maxillary expansion ranged between 4 weeks and 16 months. Fixed (acrylic plate, Haas, Hyrax and quad-helix) or removable (Hawley and Hawley expander) appliances were used for retention. CONCLUSIONS: Six months of retention with either fixed or removable appliances seem to be enough to avoid relapse or to guarantee minimal changes in a short-term follow-up.

Palmoplantar Hyperkeratosis

Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive disorder characterized by palmoplantar hyperkeratosis and early onset of severe destructive periodontitis causing premature loss of both deciduous and permanent dentitions at a young age. In this article two cases of patients with Papillon-Lefevre syndrome in late mixed dentition are presented. The objective of these case reports was to illustrate that under a controlled regime of periodontal treatment, orthodontic treatment is possible in patients with Papillon-Lefevre syndrome. In both cases, the deciduous dentition was lost prematurely shortly after eruption. The permanent teeth erupt without any guidance, and this can lead to loss of space, crowding, and collapse of the dental arch. The aim of the treatment was to expand the arch, create space to allow normal eruption of the permanent teeth, and stabilize the occlusion to help the patient achieve a normal facial appearance rather than the collapsed appearance caused by early extractions.

The Aberdeen Royal Infirmary oral and maxillofacial surgery department is involved in the joint planning of cases with the orthodontic and restorative departments of the Aberdeen Dental Hospital to agree an optimal treatment plan for patients, with input from all three specialties. A 7-year-old girl was referred to the orthodontic department by her GDP due to non-eruption of the upper left central incisor. This was related to an associated dentigerous cyst. This presentation illustrates the phases of treatment involving marsupialization of the dentigerous cyst; surgical extraction and orthodontic treatment in order to provide the patient with the optimal outcome for her dentition. A retrospective assessment of the case is presented through photographs and radiological imaging outlining the chronology of the treatment and the outcome of marsupialization of the dentigerous cyst. It highlights this more conservative surgical approach as giving the best chances of preserving unerupted teeth in a younger patient. Marsupialization of a dentigerous cyst associated with UL1 and conservative management of cystic pathology led to preservation and natural mesial eruption of UL3 into the position of UL1. The unerupted UL1 associated with cystic pathology was extracted due to its ectopic position and root dilaceration. Seven years after diagnosis of the dentigerous cyst associated with the unerupted UL1, surgical and orthodontic management has facilitated the for patients tooth to erupt into the UL1 position. Restorative treatment is being planned following orthodontic treatment to restore for patients tooth to simulate the missing UL1. CPD/Clinical Relevance: This case encourages the appropriate referral of young patients with dentigerous cysts to achieve a satisfactory outcome.

Commercial Expansion

Maxillary expansion is a common orthodontic treatment used for the correction of posterior crossbite resulting from reduced maxillary width. Transverse maxillomandibular discrepancies are a major cause of several malocclusions and may be corrected in different manners; in particular, the rapid maxillary expansion (RME) performed in the early mixed dentition has now become a routine procedure in orthodontic practice. The aim of this study is to propose a procedure that reduces the patient cooperation as well as the lab work required in preparing a customized Haas-inspired rapid maxillary expander (HIRME) that can be anchored to deciduous teeth and can be utilized in mixed dentition with tubes on the molars and hooks and brackets on the canines. This article thus presents an expander that is completely digitally developed, from the first moment of taking the impression with an optical scanner to the final solidification phase by the use of a 3D printer. This digital flow takes place in a CAD environment and it starts with the creation of the appliance on the optical impression; this design is then exported as an stl extension and is sent to the print service to obtain a solid model of the device through a laser sintering process. This “rough” device goes through a post-processing procedure; finally, a commercial expansion screw is laser-welded. This expander has all the advantages of a cast-metal Haas-type RME that rests on deciduous teeth; moreover, it has the characteristic of being developed with a completely digitized and individualized process, for the mouth of the young patient, as well as being made completely of cobalt-chrome, thus ensuring greater adaptability and stability in the patient’s mouth.

Supernumerary teeth are considered as one of the most significant dental anomalies during the primary and early mixed dentition stages. They are of great concern to the dentists and parents because of the eruption, occlusal, and esthetic problems they can cause. Supernumerary teeth occur more frequently in the permanent dentition but rarely in primary dentition. Mesiodens is the most common type of supernumerary teeth but rarely seen in lower arch. Early recognition and diagnosis of supernumerary teeth is important to prevent further complications in permanent dentition. Four cases of supernumerary teeth with mesiodens in upper and lower arch in primary dentition and their management have been discussed.

Maxillary Deficiency

The orthodontic treatment of Class III malocclusion with a maxillary deficiency is often treated with maxillary protraction either with or without maxillary expansion. The routine procedure for rapid maxillary expansion includes banding on first premolars/first deciduous molars and the permanent first molars. However in some patients who are esthetically very conscious, banding of the first premolar would not be a good esthetic option. So for such circumstances we have designed a modified hyrax splint, which does not need the first premolars to be banded.
