A modification of Andresen appliance therapy has been described with the incorporation of an anterior oral screen which isolates the anterior teeth from the vestibular musculature. The main points of interest are the rate of overjet reduction, the simplicity of construction and virtual absence of adjustment which rendered this appliance suitable in areas where orthodontic treatment was severely limited.

<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.

Abstract Backgroud To analyze the morphological changes of the anterior alveolar bone after the retraction of incisors in premolar extraction cases and the relationship between incisor retraction and remodeling of the alveolar base represented by points A and B displacements. Methods Pre- (T0) and post-treatment (T1) lateral cephalograms of 308 subjects in the maxilla and 154 subjects in the mandible who underwent the orthodontic treatment with extraction of 2 premolars in upper or lower arches were included. Alveolar bone width and height in both the maxillary and mandible incisor area were measured at T0 and T1 respectively. By superimposing the T0 and T1 cephalometric tracings, changes of points A and B, and the movement of the incisors were also measured. Then the correlation between incisor movement and the displacements of points A and B was analyzed. Results The alveolar bone width (ABW) showed a significant decrease in both maxilla and mandible (P < 0.001) except the labial side of the mandible (P > 0.05). The alveolar bone height (ABH) showed a significant increase in the labial side of maxilla and a significant decrease in the lingual side of maxilla and mandible. A strong positive correlation was verified between incisor movement and position changes of points A and B in both horizontal and vertical directions. Conclusions Anterior alveolar bone width and height generally decreased after orthodontic treatment. Incisor retraction led to significant position changes of points A and B. The decrease of anterior alveolar bone due to significant incisor retraction should be taken into account in treatment planning.

Bonded Retainers

The lower fixed retainer from cuspid to cuspid has been one of the commonly used methods of retention at the end of the orthodontic treatment. Orthodontists mostly use the lingual wire soldered to cuspid bands for the fixed lower retainer. With the advent of the new effective bonding materials many orthodontists prefer to use cuspid-to-cuspid/biscuspid-to-biscuspid bonded retainers to obtain optimal retention of lower anterior teeth both functionally and aesthetically. After experimenting with a variety of previous methods, such as the use of rubber bands, elastic threads, cotton pliers, ligature wires and silastic trays for the accurate placement and immobilization of a lower lingual retainer during the bonding, we have found that the use of two 1 to 1½ inch pieces of 0·016 inch wires tack welded to lingual wire gives the best results. It is more accurate, simple, inexpensive and designed to save the orthodontist chair time.

Lip sucking and lip biting in the primary-dentition period can cause the upper incisors to tip labially and the lower incisors to collapse lingually with the lower lip wedged between the upper and lower anterior teeth. The resulting lip incompetence further aggravates maxillary protrusion. Thus, there is a causal relationship between lip sucking/lip biting and maxillary protrusion. Orofacial myologists provide lip training to activate the flaccid upper lip and raise the child's awareness to help stop the sucking or biting of the lower lip, sometimes using an oral screen. Two primary-dentition cases with lip sucking and lip biting were treated with a functional appliance (F.A.), resulting in the elimination of the habits in 5 to 6 months along with the improvement of the overjet, overbite and facial profile. The authors prioritize myofunctional therapy (MFT) when treating open bite cases with tongue thrust in the primary dentition. However, the treatment of maxillary protrusion due to lip sucking and lip biting is approached differently with priority given to morphological improvement to create an oral environment that makes lip sucking and lip biting difficult, which is complimented with lip exercises and habituation. This combined approach was found to be effective in breaking the lip-sucking and lip-biting habits.

Abstract Introduction Objective of this study was to investigate the incidence and severity of apical root resorptions (ARR) during orthodontic treatment with aligners. Materials and methods The sample comprised 100 patients (17–75 years of age) with a class I occlusion and anterior crowding before treatment, treated exclusively with aligners (Invisalign®, Align Technologies, Santa Clara, CA, USA). The following teeth were assessed: upper and lower anterior teeth and first molars. Root and crown lengths of a total of 1600 teeth were measured twice in pre- and post-treatment panoramic radiographs. Afterwards, relative changes of the root length during treatment were calculated by a root-crown-ratio taking pre- and post-treatment root and crown lengths into consideration. A reduction of this ratio was considered as a shortening of the initial root length. Additionally, tooth movements of the front teeth were assessed by lateral cephalograms and the 3-dimensonal set up of each patient. Results All patients had a reduction of the pre-treatment root length with a minimum of two teeth. On average 7.36 teeth per patient were affected. 54% of 1600 measured teeth showed no measurable root reduction. A reduction of >0%-10% of the pre-treatment root length was found in 27.75%, a distinct reduction of >10%-20% in 11.94%. 6.31% of all teeth were affected with a considerable reduction of >20%. We found no statistically significant correlation between relative root length changes and the individual tooth, gender, age or sagittal and vertical orthodontic tooth movement; except for extrusion of upper front teeth, which was considered as not clinical relevant due to the small amount of mean 4% ARR. Conclusions The present study is the first analyzing ARR in patients with a fully implemented orthodontic treatment with aligners (i.e. resolving anterior crowding). The variety was high and no clinical relevant influence factor could be detected. A minimum of two teeth with a root length reduction was found in every patient. On average, 7.36 teeth per patient were affected.

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch and the talon cusp is a rare dental developmental anomaly seen on the lingual surface of anterior teeth. This paper presents a rare clinical case of development of talon cusp in a mesiodens with multiple lobes, which interfered with both occlusion and appearance of an 11-year-old patient. During clinical interview, the patient reported difficulty on mastication. Clinical and radiographic examination revealed that a supernumerary tooth with completely formed root was causing an occlusal interference. The supernumerary tooth was diagnosed as multi-lobed mesiodens associated with a palatal talon cusp. The treatment plan consisted in the extraction of the supernumerary tooth followed by orthodontic treatment for diastema closure and tooth alignment.

ABSTRACTObjective: The aim of this study was to document the prevalence of hypodontia in the permanent dentition among a group of Turkish sample who sought orthodontic treatment and to compare present results with the specific findings of other populations. The occurrence was evaluated in relation to gender, specific missing teeth, the location and pattern of distribution in the maxillary and mandibular arches and right and left sides.Materials And Methods: Orthodontic files of 2413 patients (1557 females-mean age: 17.78±5.41 years old and 856 males-mean age:17.02±5.47 years old) which included orthopantomograms, study models, and anamnestic data were examined for evidence of hypodontia.Results: The prevalence of hypodontia was 7.54% (8.09% for female and 6.54% for male). Hypodontia was found considerably more frequently in the maxilla than in the mandible. Similarity in the distribution of missing teeth between the right and left sides was detected. The most frequently missing teeth were the maxillary lateral incisors, followed by the mandibular and maxillary second premolars. The majority of patients had one or two teeth missing, but seldom three or more.Conclusions: Present data for hypodontia were within the wide range reported in the literature. The findings of patients with hypodontia involving the anterior teeth and others missing more than two teeth in the same quadrant were an indication of a great need for orthodontic treatment. By early detection of missing teeth, alternative treatment modalities can be planned and performed with a multidisciplinary team approach. (Eur J Dent 2007;1:167-173)

Abstract Background: The morphology of the anterior alveolar bone may change after the retraction of incisors in premolar extraction cases in orthodontics. Methods: Pre- (T0) and post-treatment (T1) lateral cephalograms of 477 subjects in the maxilla and 226 subjects in the mandible who underwent the orthodontic treatment with extraction of 2 premolars in upper or lower arches were included. Alveolar bone width and height in both the maxillary and mandible incisor area were measured at T0 and T1 respectively. By superimposing the T0 and T1 cephalometric tracings, changes of points A and B, and the movement of the incisors were also measured. Results: The alveolar bone width (ABW) showed a significant decrease in both maxilla and mandible (P<0.001) except the labial side of the mandible, which exhibited slight increase, though statistically insignificant (P>0.05). The alveolar bone height (ABH) showed a significant increase in the labial side of maxilla and a significant decrease in the lingual side of maxilla and mandible. A strong positive correlation was observed between incisor movement and position changes of points A and B both in the horizontal and vertical direction. Conclusions: Anterior alveolar bone width and height generally decreased after orthodontic treatment. Incisor retraction led to a significant position changes of points A and B.
