Dens Invaginatus

Introduction. “Dens invaginatus” is a dental anomaly which originates from the invagination of the ameloblastic epithelium into the lingual surface of the dental crown during the odontogenesis. It can cause early pulpal necrosis, abscesses, retention or dislocation of contiguous elements, cysts, and internal resorptions. It normally affects the upper lateral incisors. In the following study the authors will discuss the etiology, the physiopathology, and the surgical-orthodontic management of a rare case of impacted canine associated with dens invaginatus and follicular cyst, with the aim of highlighting the importance of taking any therapeutic decision based on the data available in the literature.Case Report. The present study describes a combined surgical-orthodontic treatment of an impacted canine associated with a lateral incisor (2.2) suffering from type III dens invaginatus with radicular cyst, in a 15-year-old patient.Discussion. When treating a dens invaginatus there are different therapeutic solutions: they depend on the gravity of the anomaly and on the association with the retention of a permanent tooth. The aesthetic and functional restoration becomes extremely important when performing a surgical-orthodontic repositioning.

This study selected the maxillary labial impacted canine as the research object to build the model of periodontal ligament (PDL) and simulate the process of orthodontic treatment. This paper obtained stress–strain curve by calculating and analyzing the data of nanoindentation experiments. The parameters were identified through curve fittings by ABAQUS. The fitting results show that the third-order Ogden model is in good agreement with the experimental data which demonstrate that the third-order Ogden model is able to reflect the material properties of the PDL. In this paper, orthodontic process of the maxillary labial impacted canine was simulated. The results show that inside and outside surfaces of PDL all have stress variation, the stress on the root apex and dental cervix of PDL is relatively large, the maximum appears at dental cervix and the minimum appears close to tooth impedance center.

Comprehensive orthodontic treatment among adult patients that required multidisciplinary approaches has been increased since a lot of them could not avail themselves with any treatment decades ago. Treatment of impacted canine in adult orthodontic patient needs to be integrated into the overall orthodontic treatment scheme. The following case report described an orthodontic treatment of 33-year-old woman with convex profile, palatally impacted of left maxillary canines and single dental crossbite. Dental midline shift associated with narrow arch form of upper arch and asymmetric tooth amount. Management of this case was started by extraction of first upper premolars in the opposite site from impacted maxillary in order to overcome dental discrepancy problem. Surgical exposure allowed the potency natural eruption of the impacted tooth. After 24-months of treatment, the impacted maxillary canines took place as integral elements in dentition and Class I Canine relationship was achieved. The success of this comprehensive orthodontic treatment also considered biomechanical and periodontal condition during treatment based on proper evaluation and good prognostic of the impacted tooth position. Providing adequate space and surgical exposure during levelling aligning phase followed by orthodontic traction and gingivectomy, were the multidisciplinary approaches of this following case. In conclusion, biomechanical orthodontic treatment related to periodontal condition must be considered in comprehensive orthodontic treatment of adult patient.

Contemporary Management

Management of impacted maxillary canines forms a sizeable proportion of orthodontic treatment provided in dental school and district general hospital settings. Patients presenting with impacted canines fall into the highest category on the Index of Orthodontic Treatment Need (IOTN). Patients who agree to have surgical exposure and subsequent orthodontic alignment of an impacted canine are committing themselves to a course of treatment that could take up to three years, towards the end of which the patient's enthusiasm may be waning. Prevention, or at least early interception of the impacted canine, could save a protracted course of treatment and avert not only the surgical morbidity associated with exposure of the impacted tooth but also the general risks associated with orthodontic treatment.

ABSTRACT Objective:  To compare anchorage condition in cases in which transpalatal arch was used to enhance anchorage in both continuous and segmented arch techniques. Materials and Methods:  Twenty cases that required first premolar extraction for orthodontic treatment and transpalatal arch to enhance anchorage were included in this study. Ten cases were treated using the continuous arch technique, while the other 10 cases were treated using 0.019 × 0.025-inch TMA T-loops with posterior anchorage bend according to the Burstone and Marcotte description. Lateral cephalometric analysis of before and after canine retraction was performed using Ricketts analysis to measure the anteroposterior position of the upper first molar to the vertical line from the Pt point. Data were analyzed using an independent sample t-test. Results:  There was a statistically significant forward movement of the upper first molar in cases treated by continuous arch mechanics (4.5 ± 3.0 mm) compared with segmented arch mechanics (−0.7 ± 1.4 mm; P  =  .01). Conclusions:  The posterior anchorage bend to T-loop used to retract the maxillary canine can enhance anchorage during maxillary canine retraction.

Abstract Objective: To investigate the influence of radiographic position of palatally impacted canines on the length of treatment for orthodontic alignment. Materials and Methods: Treatment records of 45 consecutive successfully treated patients (36 unilateral, 9 bilateral) with ectopic palatal canines treated with surgical exposure and orthodontic traction were analyzed. The sample was based on orthodontic referrals over a 3-year period in Kent and Canterbury Hospital, UK. The duration of treatment was related to radiographic parameters including the height of the impacted canine, angulation of the long axis to the upper midline, mesiodistal position of the canine tip relative to the midline and adjacent incisors, and the anteroposterior position of the canine root apex. Results: Using multiple stepwise regression analysis, the horizontal position of the canine crown relative to adjacent teeth and maxillary dental midline showed a statistically significant correlation with the duration of treatment (P =.042), explaining 7.7% of the overall variance. However, treatment duration was found to be independent of the initial canine angulation (P = .915), vertical height (P =.065), and position of the canine apex (P = .937). Conclusions: Accurate prediction of treatment duration for orthodontic alignment of palatally impacted maxillary canines is difficult. However, the mesiodistal position of the canine may be a useful predictor of treatment duration. (Angle Orthod. 2009:79;442–446.)

Abstract Objective: To analyze the clinical outcome of a prospective two-center study of second-generation palatal implants 6 months after functional loading. Material and Methods: From 2005 to 2006, 30 patients aged 12 to 41 years were included in the study. In all patients, orthodontic treatment required stationary anchorage. The palatal implants (Straumann, Basel, Switzerland) were placed in the median region of the anterior palate. Results: All implants were initially stable at the time of placement. However, two (6.7%) were lost during the unloaded healing period. The remaining 28 (93.3%) were subjected to functional loading after a mean healing period of 12 weeks. Typical signs of slight superficial inflammation were observed in the peri-implant mucosa (n = 28). During the orthodontic loading phase, the implants were equipped with either a modified pendulum appliance for distalization or a transpalatal arch for stationary anchorage to the posterior teeth. No implant loosening or loss was registered during the active treatment period. Conclusions: The failure rate of palatal implants of the second generation was low (6.7%). Slight inflammatory reactions of peri-implant tissue caused neither implant loss nor pain.

Introduction Class III malocclusions are considered one of the most difficult problems to treat. For us, the complexity of these cases is the esthetics of the face and smile because the treatment of these malocclusions without surgery produces a more retrusive face. Diagnosis and Etiology We present a case of an adult male patient with skeletal Class III malocclusion with several crowding and impacted canines, who was treated with extractions of the upper canines and lower premolars. Conclusions The result is acceptable in terms of occlusion function, esthetic of the smile, and facial esthetics.
