Background: Among tooth anomalies, missing teeth is one of the most frequent, and it can be related to different therapeutical sets of problems. Often, an integrated approach that interests both orthodontists and prosthodontists is necessary, and in some cases also the periodontists. Methods: In this paper the authors report a clinical case of a 14-year-old patient, affected by maxillary bilateral incisors agenesis, molar bilateral II class and deep bite, treated in the Department of Orthodontics and Pedodontics of the University of Messina. The orthodontic treatment target was the distal movement of the maxillary molar, and the recovery of the space necessary for the prosthetic restoration of the missing lateral incisor. Maxillary molars distal movement was performed with a Distal Jet apparatus, skeletally supported by two miniscrews (Distal-Screw, American Orthodontics, Sheboygan, WI, USA). After molar relationship correction, a multi-bracket bimaxillary orthodontic appliance was bonded using Empower Brackets (American Orthodontics, Sheboygan, WI, USA). At the end of orthodontic treatment a Maryland bridge, bonded on the central incisors and cuspids, was used in order to maintain the space necessary for the insertion of dental implants in the region of 1.2 and 2.2 Results: A class II molar relationship was corrected, with an improvement of the deep bite, and the space necessary for implant insertion was recovered Conclusion: A skeletally supported Distal Jet was efficient for molar distalization, with the advantage of not having any loss of anchorage in the anterior part of the dental arch. This apparatus does not need patient compliance, have favorable aesthetics and also give the possibility to perform asymmetric activations.

Dentoskeletal class II malocclusion due to a protruded upper dental arch is a major reason for an orthodontic treatment. In these cases, the correction of class II can be hindered by molar distalization, obtained with ‘no-compliance therapy’ that involves the use of appliances which minimize the need for such co-operation and attempt to maximize the predictability of results. The aim of this review was to outline the effectiveness of no-compliance fixed orthodontic devices in the molar distalization. After selection according to the inclusion/exclusion criteria, 16 articles from 2000 to 2019 were qualified for the final analysis. The literature shows various no-compliance fixed devices whose effect is to distalize the maxillary molars. The present revision allows to conclude that there is a need to increase the number of studies, especially with regard to the most recently introduced devices in the literature. The analysed studies allow to hypothesize that these appliances act with a minimal variability of molar distalization and disto-inclination among them, although different effects among the appliances can be observed as regards to the anchorage.

Abstract Objective: To evaluate the maxillary molar distalization and anchorage loss in two groups, one before (MD 1 group) and one after (MD 2 group) eruption of second maxillary molars. Materials and Methods: After a sample size calculation, 20 patients were recruited for each group from patients who fulfilled the following criteria: no orthodontic treatment before distal molar movement, Class II molar relationship defined by at least end-to-end molar relationship, space deficiency in the maxilla, and use of an intra-arch NiTi coil appliance with a Nance appliance to provide anchorage. Patients in the MD 1 group were without any erupted second molars during the distalization period, whereas in the MD 2 group both the first and second molars were in occlusion at start of treatment. The main outcome measures to be assessed were: treatment time, ie, time in months to achieve a normal molar relation, distal movement of maxillary first molars, and anterior movement of maxillary incisors (anchorage loss). The mean age in the MD 1 group was 11.4 years; in the MD 2 group, 14.6 years. Results: The amount of distal movement of the first molars was significantly greater (P < .01) and the anchorage loss was significantly lower (P < .01) in the group with no second molars erupted. The molar distalization time was also significantly shorter (P < .001) in this group, and thus the movement rate was two times higher. Conclusions: It is more effective to distalize the first maxillary molars before the second molars have erupted.

Abstract The aim of this case presentation is to outline some of the advantages that an adjunct orthodontic treatment can offer in a comprehensive oral rehabilitation of an adult patient. Adjunctive orthodontic treatment is usually limited to a dental arch or to a group of teeth within an arch. The purpose of dental movements in this case will be to position the teeth in a way that makes the restoration or replacement of damaged or missing teeth as easy as possible and with minimal dental tissue sacrifice. In addition, the improved position of the teeth will create a healthier periodontal environment that is easier to maintain over time.

Objective: To evaluate the severity of the dental arch relationships and the treatment outcomes of reverse headgear (RHG) in southern Chinese patients with unilateral cleft lip and palate (UCLP). Design: A retrospective study. Setting: Faculty of Dentistry, The University of Hong Kong. Patients: Thirty-eight UCLP patients with complete records. Among them, 14 were later treated with RHG (RHG group) and 24 were under review (non-RHG group) before definitive orthodontic or in conjunction with orthognathic surgery. Interventions: Study models at T1 (aged 9.4 ± 0.4 years old), prebone grafting and before any orthodontic treatment started; T2 (aged 11.3 ± 0.6 years old), after bone grafting, and RHG treatment (RHG group) or under review (non-RHG group); and T3 (aged 15.3 ± 3.2 years old), pretreatment of definitive orthodontic or in conjunction with orthognathic surgery. Main Outcome Measures: With satisfactory intra- and interexaminer agreement proven by the kappa value, the dental arch relationships of the study models at T1, T2, and T3 were assessed by a solo calibrated examiner using the GOSLON Yardstick. Results: The median GOSLON score for southern Chinese patients with UCLP at T1 was 4.0. Sixty percent of the patients were categorized as “poor” at T1. RHG significantly improved dental arch relationships from T1 to T2, and the improvement was maintained until T3 assessed by the GOSLON Yardstick. Conclusions: The dental arch relationships in southern Chinese UCLP patients at 8 to 10 years old are unfavorable. RHG treatment shows positive effects in improving the dental arch relationships in UCLP patients, as assessed by the GOSLON Yardstick.

Agenesis of mandibular second premolar is reported to be 2.4–4.5%. The diagnosis can be set on at average 9 years of age. Early treatment in the form of extraction of the second primary molar and in some cases also the remaining three second premolars and comprehensive orthodontic treatment are often a good treatment solution. In vertical deep bite cases, cases with spacing in the dental arch, mandibular posterior rotation and for extractions disadvantageous growth pattern, a treatment with retaining of the primary molar must be taken in consideration. When there is no or minor infraocclusion, root resorption less than half of the root length, and no caries or fillings at the age of 12–13 years, there is a good prognosis for longtime survival of the primary molar.

Abstract Even from the distant past the aesthetic perception in an individual was diminished by the presence of gap between the central incisors. This condition is found under the term “dents du bonheur” or “lucky teeth” and is encountered even among world famous figures including Brigitte Bardot, Eliah Wood, Madonna, Zac Efron, Amy Winehouse and Elton John. The teeth gaps are still considered main reasons for dissatisfaction of the dental patients and reasons for the requirement of aesthetic treatment. The purpose of this study is to exhibit the influence of the etiological factors in the occurrence of dia-stema mediana classified according to the dominance of their occurrence expressed in percentage values. Materials of this investigation were 100 patients with diastema mediana from the following factors: inheritance, disproportion in the dental arches, inborn or acquired missing teeth, harmful oral habits, high insertion of the labial frenulum as well as mesiodens. After the diagnosis and evaluation of the etiological factor for diastema mediana was performed, a decision regarding the course of treatment was made in direction of the removal of the etiological factor at an early age and orthodontic treatment. The end of the orthodontic treatment in a group of the patients was the beginning of prosthodontic reconstruction. From our clinical investigation we came to the realization that in 49 patients (49%) the hereditary influence was a dominant factor, next followed disproportions and discrepancies in the dental arch in 14 (14%), inborn or acquired missing teeth in 11 patients (11%), harmful oral habits in 10 (10%), high frenulum insertion in 4 (4%), and pathological objects between central incisors, mesiodens, iatrogenic factors and periodontal disease, in 3 of the clinical cases (3%) each. We concluded that the occurrence of diastema mediana is multi-causal. The dominant place is occupied by the hereditary factors. With regard to the mutual relationship between the multitudes of factors in the occurrence of diastema mediana, the diagnosis should be made conciliary and the clinical treatment should be interdisciplinary including a prosthodontist, orthodontist and oral surgeon.

Introduction. Functional maxillary orthodontics has a large number of different mobile devices with different effects on craniomandibular system and great capabilities in solving many orthodontic problems. The aim of this article was to show the effects of 9-month treatment of malocclusion class II, division 1 in a 14-year-old female patient using pre-fabricated functional appliance Trainer T4CII. Case Outline. Skeletal distal relation, deep bite, increased overjet, narrowness and irregular position of upper and lower frontal teeth are indicated for orthodontic treatment with fixed appliance. After refusal of fixed appliance therapy, a female patient was proposed treatment with mobile orthodontic appliance. A pre-fabricated functional appliance Trainer T4CII was delivered to the patient. She was motivated and she was wearing appliance at night and 2-3 hours during the day. After 9 months of treatment there was a significant improvement in the position of upper and lower frontal teeth and reshaping of upper and lower dental arch, yet overbite and overjet were corrected. Conclusion. Surprisingly good and fast improvement of all problems within class II, division 1 in a 14-year-old patient was achieved with prefabricated functional appliance Trainer T4CII.

Third maxillary molar prediction for impaction and eruption should be part of the orthodontic treatment planning. In our study we evaluated the reliability of some linear and angular measurements used for the assessment of maxillary third molar status by comparing them before and after orthodontic treatment. 208 upper third molars were analyzed, 148 at patients who undergone non extraction orthodontic treatment and 60 at patients where first premolar extractions were performed.We analyzed on orthopantomograms taken at the beginning and at the end of the orthodontic the ratio between the dimension of the retromolar space and the mesio distal diameter of the third molar, the angle between the long axis of third molar and the occlusal plane and the angle between the long axis of the second and third maxillary molars. We found significant changes in retromolar space dimension after orthodontic treatment with premolars removal and slight average increase in the non extraction group. We didn’t find significant statistical differences before and after orthodontic treatment neither between the angulations of the maxillary third molar with the occlusal plane, nor with the second upper molar (p>0.05) in both groups. The conclusion is that the type of orthodontic treatment has little or no influence upon third molar angulation and this parameter can be used as a predictive factor for third molar status from the beginning of the orthodontic treatment.

Maxillary molar distalisation is one of treatment methods for patients with Angle class II. Intraoral appliances supported by patient’s own teeth inevitably lead to loss of anchorage. Mini-implants are additionally used to reduce this side effect. The area of the hard palate is the best anatomical place to attach mini-implants, and it provides the lowest risk of complications. <b>Aim.</b> To present issues associated with appliances used for maxillary molar distalisation that are based on bone anchorage in the hard palate region. <b>Material and methods.</b> The literature review using the PubMed database and the Polish Medical Bibliography with the following key words: molar distalisation, orthodontic miniimplants, skeletal anchorage. 37 positions from the years 1996–2018 were selected and analysed. <b>Results.</b> As a result of the literature review, 37 articles describing nine distalisation appliances modelled on three basic constructions: Pendulum, Distal Jet and Keles Slider, and the MCPP appliance were identified. <b>Summary.</b> Distalising appliances supported by palatal mini-implants do not lead to loss of anchorage in the anterior segment. At the stage of anterior teeth retraction they can be used for stabilisation of the distalised segment. They are less visible compared to extraoral appliances or those placed on the external side of the dental arch. They can be used simultaneously with fixed braces or during preparation for subsequent therapy with fixed braces. Depending on the design, they are not free of the side effects typical of the prototypes they originate from, i.e. rotation and inclination of molars. The most parallel distal movement of teeth is made possible by appliances whose force acts at the height of the CR (centre of resistance) of teeth being moved.

<p><strong><em>Background:</em></strong><em> One of the most common inflammation disease in the oral cavity for the past few years is the aggressive form of periodontitis. Common signs of aggressive periodontitis is the mobility of teeth especially in incisive and first molars, and occuring mostly in young patient. Young patients whose losing her anterior teeth, are a real challenge for dentist and prosthodontist. Prosthodontist need to consider both functional and esthetic aspects. <strong>Objective:</strong> Rehabilitation of young adult patient with aggressive periodontitis by an interdisciplinary approach of orthodontist and prosthodontist. <strong>Case Description:</strong> A young woman, suffered from aggressive periodontitis with major complain of her teeth mobility, especially incisive and first molar in mandible. She had undergone periodontal treatment, but the result was failed. The anterior teeth in mandible need to be extracted, therefore patient wished not to be in edentulous state. As preliminary treatment, we choose immediate denture to replace the anterior mandible teeth. We faced difficulties in mandible, because her right canine weren’t in the proper dental arch. So we asked orthodontist to place fixed orthodontics in mandible, to get the canine back in the proper arch. We’ve chosen orthodontic treatment,because we didn’t want to extract the canine teeth. We evaluated in six months and after the canine back in the proper arch, we proceed to long span bridge in mandible as our definitive treatment. <strong>Conclusion:</strong> By not extracting the canine teeth, we got some advantages, especially patient psychically was happier with her own teeth. The collaboration with another dentistry field, provides us better treatment for patient. After treatment, patient had no complaints and was happy with her new smile.</em></p><p><strong><em>Keywords:</em></strong><em>  Prosthodontic rehabilitation, aggressive periodontitis, orthodontic treatment, esthetic</em><em>.</em></p><strong><em>Correspondence:</em></strong><em> Chaterina Diyah Nanik.
