Dento-maxillary disharmony is characterized as disproportion between tooth size and dental arch. This case report describes the treatment progress of a patient with dento-maxillary disharmony with Class I malocclusion using fixed orthodontic appliances. The patient is a 19-year-old female who came with chief complaint of crowding and ectopic upper canines. Correction of crowding and deep bite was achieved by fixed appliance with extraction. In Class I malocclusion, severity, etiology, and type of disharmony guide the treatment plan for optimal results.

Crowding is one of the most common findings in orthodontic patients. This case report describes the correction of anterior crowding with interproximal reduction (IPR). The case is that of a 24-year-old female patient who consulted for irregularly placed anterior teeth. Fixed appliances were placed followed by IPR. Treatment time was 18 months. Class I molar relation was maintained, with normal overjet and overbite. IPR is effective for treatment of patients with Class I malocclusion with anterior moderate crowding.

Crowding and protrusion are some of the most common dental cases worldwide. The patient was a 20-year-old female who consulted for severe crowding, protrusion, and deep bite. Clinical examination and cephalometric measurement showed Class I skeletal and proclined incisor. Two step retraction technique was used to correct the condition. Management of tooth tissue discrepancy by the extraction of four premolars is one of the options in the treatment of crowding.

The maxillary lateral incisor is the second most common congenitally absent tooth. This is a case of a 25-year-old with maxillary lateral incisors agenesis, multiple maxillary anterior diastema. Pre-adjusted technique was used, gingivectomy and frenectomy to release tooth movement. Patient’s profile was straight, interdental relationship was class I, enlarged space of maxillary lateral incisors, space was replaced by prostheses. The treatment of maxillary lateral incisors agenesis responsible for orthodontic, periodontic and prosthodontic achieved a pleasant aesthetic and function.

Background: Cone-beam computed tomography is being utilized in more clinical contexts and determining bone density with this method is becoming more important. Dentists, particularly dentomaxillofacial radiologists, orthodontists, and oral surgeons, must have a solid understanding of gray value. The gray values acquired from conebeam computed tomography images are used to assess dental implant bone density, diagnose dental ankylosis, and diagnose and differentiate pathological lesions. Objective: To determine the difference in the gray value of the trabecular bone in the impacted and normal erupted maxillary canine teeth using cone computed tomography. Methods: We retrospectively evaluated the cone-beam computed tomography images of patients scheduled for orthodontic treatment at the Universitas Airlangga Dental and Oral Hospital. On cross-sectional cone-beam computed tomography images, the region of interest determination of 5 mm2 in the area was placed in the trabecular bone and the gray value measurements were collected using Digital Imaging and Communications in Medicine (OnDemand3D™) dental software. The images were categorized by type of impacted canine teeth after assessing the gray values of all the teeth. Using images on the mesial, distal, buccal, and palatal areas, gray values of impacted and non-impacted teeth were compared. We used the SPSS 24 software. Results: From a total of 13 patient radiographs, we found types I (6/13), II (6/13), and VII (1/13). The mean pixel values of impacted maxillary unilateral canine teeth were 1972.92 (mesial), 2016.55 (distal), 1990.66 (buccal), and 1904.39 (palatal). The mean pixel values of normal erupted maxillary canines were 1754.93 (mesial), 1710.53 (distal), 1852.94 (buccal), and 1674.49 (palatal). There were significant differences between impacted and normal erupted maxillary canines: mesial (P = 0.018), distal (P = 0.000), buccal (P = 0.003), and palatal (P = 0.036). Conclusion There were statistically significant differences between affected and unaffected gray values in the canines in FOV size 51 × 55 mm. However, no statistically significant differences were found in the gray values in trabecular bone of unilateral maxillary impacted canines and normal erupted canines on the mesial, distal, buccal, and palatal sides.

Crowding is the most common dental case worldwide. This case report describes the diagnosis and management of a 20-year-old woman with severe crowding, deep bite, and midline shifting. The patient presented with the chief complaint of crowding and an unaesthetic smile. Upon examination, the patient had Angle Class I Malocclusion. The severe crowding was treated comprehensively and successfully corrected using fixed orthodontic appliances and without extraction, only interproximal reduction (IPR).
Class I malocclusion

Skeletal Class III malocclusion is a complex malformation with a prevalence of 81.6% in Airlangga University Dental Hospital, distributed in patients aged 15-45 years old. Camouflage treatment of skeletal Class III malocclusion improves prognosis with a mild-to-moderate shift. This study aimed to discuss orthodontic camouflage as an option for adult patients with Class III malocclusion, emphasizing its indications, implications, and expected results. This report presents the case of a 17-year-old male patient with poor facial aesthetics associated with protruded chin, abnormal functional shift, and temporomandibular joint pain. The facial profile was concave with lower anterior multiple diastemas, mandibular lip protrusion, mandibular displacement, and anterior crossbite. This case was treated by camouflage therapy using straight wire appliance system combined with elastic class III. After 24 months of treatment during the pandemic, the mandibular displacement and the crossbite were corrected, the teeth were arched, the anterior crossbite fixed, and the profile became convex. Camouflage orthodontic treatment can be an effective management option to achieve functional occlusion, stability, and a satisfactory aesthetic impression in adult patients with mild to moderate skeletal Class III deformities, anterior cross bite, and functional shift.

Maxillary Central diastema is common and normal for the growth and development of the anterior segment. If the central diastema persists after the eruption of the permanent cuspids, the orthodontist should clarify the etiology and establish a treatment plan. This case report discusses a 22-year-old woman with anterior crossbite and central diastema due to a high maxillary labial frenulum attachment. Treatment was performed using a fixed orthodontic appliance with a posterior bite raiser. Frenectomy was performed at the end of the orthodontic treatment.

Class I malocclusions with severe crowding and tooth size discrepancies may be successfully treated orthodontically with extraction therapy, and co-management with other specialists. Correction of the discrepancies will optimize occlusal result (overjet, overbite, midline shift, and smile esthetics). This is a case of a 19-year-old male with severe crowding in upper and lower teeth and peg lateral incisor. The patient had malocclusion Class I. This case was treated comprehensively and successfully using fixed orthodontic appliances with extraction of four premolars, and veneer composite for peg lateral incisor with the help of a conservative dentist at the end of orthodontic treatment.
Malocclusion, Angle Class I

The most common occlusal feature of Class I malocclusion is crowding. Crowded and irregular teeth occur in a majority of the population and are the most common complication in adults. This is a case report of a 21-year-old woman with moderate crowding and a missing lower left first molar. The first permanent molars are sometimes unnoticed by the child or their parents and bring a risk of caries to the first permanent molar. Caries in the first molars that persist without any treatment will give a poor prognosis. Treatment was performed using a fixed orthodontic appliance with the extraction of the two upper and one lower first premolars.
