Maxillary Deficiency

Transverse maxillary deficiency may be associated with sagittal or vertical problems of the maxilla or mandible. It may contribute to unilateral or bilateral posterior crossbite, anterior dental crowding, and unesthetic black buccal corridors on smiling. An adequate transverse dimension is important for stable and proper functional occlusion. Surgically, assisted rapid palatal expansion has been the treatment of choice to resolve posterior crossbite in skeletally mature patients. The following case report presents an adult Class III skeletal patient with an anterior open bite and bilateral posterior crossbite which was treated by surgically assisted rapid maxillary expansion with satisfactory outcomes.

Maxillary deficiency in the transverse dimension is a common problem in children. The conventional management of such malocclusion is with conventional rapid maxillary expansion. The beneficial effects of such an orthodontic therapy are explained in detail in the literature. But there are also negative effects of conventional rapid maxillary expansion. Thus, the improvements in the methods of expansion has led to discovery of miniscrew assisted rapid palatal expansion. The miniscrew assisted rapid palatal expansion are supported by mini implants and thus enable better skeletal expansion of maxilla. This article will discuss the favourable effects, negative effects, and clinical uses of conventional and miniscrew assisted rapid palatal expansion.

(1) Background: To investigate condylar position in subjects with functional posterior crossbite comparing findings before and after rapid maxillary expansion (RME) treatment through 3D analysis; (2) Methods: Thirty-two Caucasian patients (14 males, mean age 8 y 8 m ± 1 y 2 m; 18 females mean age 8 y 2 m ± 1 y 4 m) with functional posterior crossbite (FPXB) diagnosis underwent rapid palatal expansion with a Haas appliance banded on second deciduous upper molars. Patients’ underwent CBCT scans before rapid palatal expansion (T0) and after 12 months (T1). The images were processed through 3D slicer software; (3) Results: The condylar position changes between T1 and T0 among the crossbite and non-crossbite sides were not statistically significant, except for the transversal axis. At T1, the condyles moved forward (y axis) and laterally (x axis), they also moved downward (z axis) but not significantly; (4) Conclusions: Condilar position in growing patients with functional posterior crossbite did not change significantly after rapid maxillary expansion.

Summary Background Miniscrew-Assisted Rapid Palatal Expansion (MARPE) is a non-surgical treatment for transverse maxillary deficiency. However, there is limited evidence concerning its efficacy. Objectives This systematic review aims to evaluate the efficacy of MARPE in late adolescents and adults by assessing success rate and skeletal and dental transverse maxillary expansion, as well as treatment duration, dental and periodontal side effects and soft tissue effects. Search methods Seven electronic databases were searched (MEDLINE, Embase, Cochrane Library, Web of Science, Scopus, ProQuest and ClinicalTrials.gov) without limitations in November 2020. Selection criteria Randomized and non-randomized clinical trials and observational studies on patients from the age of 16 onwards with transverse maxillary deficiency who were treated with MARPE and which included any of the predefined outcomes. Data collection and analysis Inclusion eligibility screening, data extraction and risk of bias assessment were performed independently in duplicate. When possible, exploratory meta-analyses of mean differences (MDs) with their 95% confidence intervals (CIs) were conducted, followed by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) analysis of the evidence quality. Results Eight articles were included: two prospective and six retrospective observational studies. One study had a moderate risk of bias, whereas seven studies had a serious risk of bias. GRADE quality of evidence was very low. MARPE showed a high success rate (mean: 92.5%; 95%CI: 88.7%–96.3%), resulting in a significant skeletal width increase (MD: 2.33 mm; 95%CI: 1.63 mm–3.03 mm) and dental intermolar width increase (MD: 6.55 mm; 95%CI: 5.50 mm–7.59 mm). A significant increase in dental tipping, a decrease in mean buccal bone thickness and buccal alveolar height, as well as nasal soft tissue change was present (P < 0.05). The mean duration of expansion ranged from 20 to 126 days. Limitations One of the main drawbacks was the lack of high-quality prospective studies in the literature. Conclusions and implications MARPE is a treatment modality that is associated with a high success rate in skeletal and dental maxillary expansion. MARPE can induce dental and periodontal side effects and affect peri-oral soft tissues. Given the serious risk of bias of the included studies, careful data interpretation is necessary and future research of higher quality is strongly recommended. Registration PROSPERO (CRD42020176618).

Maxillary Deficiency

Orthodontic treatment in patients with orofacial cleft such as cleft lip and palate or isolated cleft palate is challenging, especially when the patients exhibit severe maxillary growth retardation. To correct this deficiency, maxillary expansion and protraction can be performed in the first phase of orthodontic treatment. However, in some cases, the malocclusion cannot be corrected by these procedures, and thus, skeletal discrepancy remains when the patients are adolescents. These remaining problems occasionally require various orthognathic treatments according to the degree of the discrepancy. Here, we describe one case of a female with isolated cleft palate and hand malformation who exhibited severe maxillary deficiency until her adolescence and was treated with multiple orthognathic surgeries, including surgically assisted maxillary expansion (surgically assisted rapid palatal expansion), LeFort I osteotomy, and bilateral sagittal split osteotomy in order to correct severe skeletal discrepancy and malocclusion. The treatment resulted in balanced facial appearance and mutually protected occlusion with good stability. The purpose of this case report is to show the orthodontic treatment outcome of 1 patient who exhibited isolated cleft palate and subsequent severe skeletal deformities and malocclusion which was treated by an orthodontic-surgical approach.

Rationale. Myotonic dystrophy (MD) is a multisystemic autosomal dominant disease characterized by myotonia and progressive muscular weakness and atrophy. Objective. The purpose of this study was to describe the dental, skeletal and muscular features in a family with myotonic dystrophy type II and to discuss possible therapeutic strategies. Methods and results. This study presents the case of a family (a mother and two daughthers) diagnosed with myotonic dystrophy type II. Beside the medical history and genetic tests, each subject underwent a clinical examination including impression taking, intra- and extraoral photographs and cephalometric analysis. Our investigations revealed alterations in the transversal and vertical planes. Conclusions. Our findings were consistent with previously reported craniofacial features of patients affected by myotonic disorders, and they may be important diagnostic signs of a congenital muscular disease. We found that the most predominant malocclusions were the anterior open bite and posterior crossbite, but the tendency to class III malocclusion is in contradiction with their findings.

ABSTRACT Treatment of hyperdivergent skeletal Class III malocclusion is challenging for orthodontists, and orthognathic-orthodontic treatment is usually required. This report presents the successful nonsurgical treatment of a 20-year-old man who had a skeletal Class III malocclusion with anterior open bite, anterior and posterior crossbite, hyperdivergent growth pattern, steep occlusal plane, early loss of three first molars, and an uncommon convex profile with a retruded chin. An orthodontic camouflage treatment plan was chosen based on the etiology and the patient's complaints. Tooth #37 was extracted. Miniscrews were used for uprighting and intruding of the lower molars, distalization of the lower dentition, and flattening of the occlusal plane. After 34 months of active treatment, Class I relationships, proper anterior overjet and overbite, flat occlusal plane, and an esthetic facial profile were achieved. The results demonstrated that the biomechanics involved in the nonsurgical treatment assisted with miniscrews to distalize the mandibular dentition and flatten the occlusal plane while keeping the mandibular plane stable was effective for treating this hyperdivergent skeletal Class III patient with a convex profile and anterior open bite.

Summary Background/objectives This research aimed to study the malocclusions of children and adolescents with myotonic dystrophy type 1 (DM1), in respect to healthy individuals, and trace the occlusal changes that occurred in these individuals during growth. Materials/methods Thirty-six dental casts, from children and adolescents with DM1 living in western and southern Sweden, were compared with a control group of 50 healthy individuals. To identify potential changes in occlusal traits, 26 casts were assessed and followed-up over a median time of 9 years. Independent samples t-tests were used to compare the two groups and their changes over time. Paired samples t-tests tested changes over time within each group (P < 0.05). Results DM1 patients had a higher prevalence of anterior open bite, posterior crossbite, and Class III malocclusions. When compared to controls, patients presented smaller upper and lower intermolar as well as intercanine widths. In both groups, the individuals revealed longitudinal changes with a decrease in both upper and lower arch lengths and an increase on the palatal vault height. During the follow-up period, the prevalence of malocclusions remained almost the same, only significantly differing regarding the changes that occurred between groups referred to the upper intermolar width, which decreased among DM1 patients. Conclusions/implications In comparison to healthy controls, children and adolescents with DM1 have shown already at an early age a higher prevalence of both anterior open bite and posterior crossbite. These occlusal traits did not change with time apart from the upper narrow intermolar width, which further decreased with time.

Clinical Interest

We report a 16-year-old boy who had all the typical manifestations of achondroplasia but also had a skeletal and dental class III malocclusion, a narrow maxilla, macroglossia and an open bite between the posterior teeth. The narrow maxilla and bilateral cross-bite were treated with rapid palatal expansion. The open bite and irregular teeth were corrected with fixed orthodontic treatment, taking account of the macroglossia. This case is of clinical interest since dental class III malocclusion, posterior open bite, macroglossia and benign migratory glossitis have not previously been reported in achondroplasia.
