RESUMO

This case report describes the orthodontic treatment of a patient with severe crowding; the maxillary right canines were ectopic, positioned far to the buccal side, and superimposed on the lateral incisors in near-transposition. Treatment included extraction of the 4 first premolars. A transpalatal bar was used as an anchorage device, and beta-titanium T-loop springs (0.019 × 0.025″) were used to better control the ideal force applied to retract the maxillary canines. A segmental T-loop spring was used as if it were a modified system of the segmental archwire technique. After the canines were retracted and space created for the anterior teeth, the latter were included in the treatment and the treatment was finished in the usual manner. Excellent results were achieved, both esthetic and functional. The treatment choices and their straightforward approach were appropriate, yielding predictable and stable results in the long term.

RESUMO

OBJECTIVES: The early interceptive treatment of palatally displaced canines (PDCs) has for decades been based on their position in panoramic radiographs. In the 1990s, cone-beam computed tomography (CBCT) started to become popular in cases with PDCs. The aims of this prospective study were to evaluate the agreement of PDC sector position and angle to midline between panoramic radiographs and CBCT scans. METHODS: PDC sector and angle to midline were measured in panoramic radiographs and CBCT scans in 58 consecutive patients with 64 PDCs. Kappa with linear weighting was used to assess the agreement between the measurements of PDC sector position and Bland-Altman limits of agreement to assess the agreement between the PDC angular measurements in the 2 methods. RESULTS: PDC sector position and angle to midline had systematically higher values in panoramic radiographs compared with those in the CBCT scans. The agreement of sector position between the methods was fair: weighted kappa 0.36 (95% CI 0.24-0.49). The mean difference in angle was almost 7° (95% CI 5.9°-7.9°) higher in panoramic radiographs compared with CBCT. CONCLUSIONS: Panoramic radiographs overestimate PDC sector and angle to midline position, compared with the use of CBCT scans, but clinically the differences are quite modest. Panoramic radiographs could be considered good enough for rendering PDC position when the need for 3D information is not crucial for treatment planning.

RESUMO

Short root anomaly (SRA) is a rare familial dental condition that is often misdiagnosed. Orthodontic treatment of patients with SRA is challenging because it is difficult to diagnose, it may be accompanied by other dental anomalies, and it has been reported to contribute to additional susceptibility to root resorption during orthodontic treatment. In this article, we describe a methodical and evidence-based means of diagnosing and orthodontically managing a patient with SRA. The patient had additional challenges, including impacted and ectopic teeth. An individualized treatment plan that incorporated efficient and effective mechanics led to a well seated occlusion and an esthetic smile.

RESUMO

Ectopic eruption originates from the malpositioning of a tooth bud ending in the eruption of the tooth in an improper direction. This anomaly is a consequence of ectopic development of the tooth germ. This condition gives rise to significant aesthetic and occlusal issues in the early mixed dentition stage. The most frequently influenced teeth are the maxillary first molars, accompanied by the maxillary cuspids. Ectopic eruption is seldom seen and might derive from traumatic injury. In some cases, hyperplastic and fibrotic gingival tissue may lead to ectopic eruption of a permanent incisor. Managing ectopically erupting teeth generally rests on several reasons including extraction of supernumerary tooth, removal of cyst and excision of hyperplastic tissue and subsequent to orthodontic movement of tooth if necessary. In this case, the use of Er, Cr: YSGG lasers for the correction of hyperplastic soft tissues involving ectopically erupting permanent incisors are depicted considering two cases.

RESUMO

Tooth transposition is one of the most difficult dental anomalies to treat in the dental clinic. Several factors must be taken into account with a view of making the best decision. The aim of this study was to discuss treatment modalities for tooth transposition, their advantages and disadvantages. Additionally, it aims at presenting a clinical case of transposition between canine and lateral incisor in the upper quadrant on the right side. The treatment of choice was extraction of one transposed tooth. A multidisciplinary approach involving Orthodontics, Cosmetic Dentistry, and Periodontology was necessary to allow proper esthetic and functional outcomes to be achieved.

RESUMO

The aim of this case report is to describe the treatment of an 11-year-old boy who was referred to an endodontist for evaluation of external inflammatory root resorption in the distal apical third of the permanent maxillary left lateral incisor, caused by deviation in the eruption path of the permanent maxillary left canine. The results of the pulpal sensitivity test of the permanent maxillary left lateral incisor were inconclusive and similar to those for the homologous tooth, so the endodontist opted for a clinical and radiographic follow-up. The patient was referred to an orthodontist, who placed a fixed Haas-type palatal expander. After the eruption of all permanent teeth, the orthodontist placed a fixed orthodontic appliance. After approximately 3 years of monitoring, bone repair with dental remodeling was observed, and the results of a pulpal sensitivity test were positive. This case demonstrates that proper monitoring is critical in establishing the diagnosis and treatment plan and ultimately to the success of clinical management.

RESUMO

Among eruption anomalies, tooth transposition is considered the most difficult to manage clinically and represent a real challenge for the clinician. Uncorrected, the results are often both functionally and esthetically unsatisfactory. Treatment of this anomaly varies from acceptance to correction and should take into account aspects, such as age, dental morphology, malocclusion, facial esthetics, stage of root development, position of root apices, and magnitude of the transposition. Acceptance of the transposition is the predominating treatment strategy in case reports in the literature. Our aim in this article is to present two cases with complete maxillary canine first premolar transposition where the transposition was corrected.

RESUMO

Background: Displaced maxillary permanent canine is one of the more frequent findings in canine eruption process and it’s easy to be outlined and early diagnosed by means of x-ray images. Late diagnosis frequently needs surgery to rescue the impacted permanent canine. In many cases, interceptive treatment to redirect canine eruption is needed. However, some patients treated by interceptive means end up requiring fenestration to orthodontically guide the canine to its normal occlusal position. It would be interesting, therefore, to discover the dental characteristics of patients who will need additional surgical treatment to interceptive treatment. Material and Methods: To study the dental characteristics associated with canine impaction, conventional statistics have traditionally been used. This approach, although serving to illustrate many features of this problem, has not provided a satisfactory response or not provided an overall idea of the characteristics of these types of patients, each one of them with their own particular set of variables. Faced with this situation, and in order to analyze the problem of impaction despite interceptive treatment, we have used an alternative method for representing the variables that have an influence on this syndrome. This method is known as Self-Organizing Maps (SOM), a method used for analyzing problems with multiple variables. Results: We analyzed 78 patients with a PMC angulation higher than 100º. All of them were subject to interceptive treatment and in 21 cases it was necessary to undertake the above-mentioned fenestration to achieve the final eruption of the canine. Conclusions: In this study, we describe the process of debugging variables and selecting the appropriate number of cells in SOM so as to adequately visualize the problem posed and the dental characteristics of patients with regard to a greater or lesser probability of the need for fenestration (AU)

RESUMO

Ectopic eruption is a deviation from the normal eruption pattern, making the tooth erupt out of its normal position, and possibly causing resorption of adjacent primary teeth. A wide range of etiological factors may be responsible for ectopic eruption of the teeth, so their management depends on the correction of the established etiological factor. The present case report describes an unusual case of ectopically erupted central incisor encased within an abnormally thickened labial frenum, which was treated by orthodontic repositioning of the ectopically erupting tooth after frenectomy.

RESUMO

This review article describes the changing approach to the management of various impacted teeth. Currently, more third molars are being retained, and it is likely that more patients will develop impactions than a generation ago because of non-extraction orthodontic treatment plans. There are still valid reasons for the surgical removal of selected third molars during the teenage years, during which time impaction can be anticipated to avoid the higher rate of morbidity associated with later removal. Palatally-impacted canines (PIC] can now often be managed with interceptive and non-surgical approaches, which are attractive options. The various approaches addressed in the literature are discussed.

RESUMO

This is a case report of a 71-year-old male with three months of gradually increasing irritation, secretion and right-sided nasal stenosis. The patient had not experienced any facial trauma nor had he had any previous surgical intervention to the nasal or oral cavity. An examination of the nasal cavity raised the suspicion of a foreign body in the right nasal floor. A computed tomography was performed and a high-density, foreign body was identified. The patient was referred to the local department of otorhinolaryngology, where an ectopic tooth was successfully removed in local anaesthesia.

RESUMO

BACKGROUD: The aim of this study was to describe an experimental study carried out in a group of young patients with an early diagnosis of atypical eruption pattern of the maxillary canines and first premolars, identified and treated by rapid palatal expansion (RPE) interceptive therapy. METHODS: This study involved 20 young patients aged between 8 and 12 years (mean age 10±0.3 years). Patients were randomly divided into two equal groups (10 patients in each group). The patients in the first group underwent a rapid palatal expansion with an hyrax-type expander. The appliance was activated twice a day for 15 days in order to obtain 7.5 mm of palatal expansion. Then, it was left in situ for six months. The second group was the control group and patients were not treated but only observed. The total number of dental transposition were 30 couple (15 in the first group and 15 in the control group). RESULTS: Among the first group, 13 couple of dental transposition reached the right position in the arch. Two of them remained transposed. Among the control group, 12 of them remained transposed and 3 reached the right position. CONCLUSIONS: Transpositions of the maxillary canines and first premolar is a common tooth malposition in children. Early diagnosis will permit to perform an interceptive treatment that will prevent the full development of transposition.

RESUMO

Ectopic eruption of a permanent tooth involves abnormal resorption of a portion or all of the adjacent primary tooth. Among the most commonly ectopically erupted teeth are the permanent first molars. Ectopically erupting molars may require intervention to allow for full eruption, or they may spontaneously self-correct and erupt into occlusion. Decisions regarding the necessity of intervention, its ideal timing, and intervention type are multifactorial. Treatment options for the ectopically erupting permanent first molar include the elastomeric separator, brass wire, pre-fabricated clip separator, custom made appliances (Humphrey appliance, Halterman appliance), or extraction of the primary molar. Early intervention when indicated can ensure proper full eruption of the permanent first molar and prevent mesial angulation, arch perimeter loss, tooth impaction and ankylosis. Two cases are described that manage ectopic eruption of the permanent first molar.

RESUMO

Transposition, which is a dental anomaly, is defined as a positional interchange of two adjacent permanent teeth found on the same dental arch. In this case report, we present the outcomes of fixed orthodontic treatment in a patient with unilateral mandibular lateral incisor-canine transposition. Following orthodontic treatment, transposed teeth were placed into their normal anatomicalpositions on the mandibular dental arch by applying mild orthonitc forces, and smile esthetics was restored with ideal. Angle's Class I occlusion.

RESUMO

Dental crowding can frequently result in a tooth becoming palatally blocked-out. When the tooth is displaced too far, tying the tooth to the archwire can become unfeasible. A modified "singshot" technique is presented to bring a blocked-out bicuspid into the arch. The lastomeric chain acted as a "sling shot" squeezing the bicuspid in, hence the name "sleeze."

RESUMO

Permanent teeth that remain impacted could lead to the early loss of primary teeth and cause space problems in dental arches. We present two cases of ectopic eruption of the permanent maxillary first molars treated with soft distal movements using a modified Nance palatal arch (NPAm). The wire was soldered to the band and positioned distally to serve as support for the elastic chain, which was attached to a bonded button on the occlusal surface. After a few months, the ectopic eruption was corrected, preserving the adjacent primary teeth and restoring the occlusion. An NPAm is a viable option for distalization and space recovery in the maxillary arch.
