1/64. Implant anchorage for the occlusal management of developmental defects in children: a preliminary report.Congenital anomalies and developmental defects of the face and jaws often present orthodontic anchorage challenges in which the residual dentition cannot be adequately positioned for restorative objectives. This article presents a method of classification for the formulation of implant-based treatment protocols in children, reviews the application of implants in the developing dentition, and provides guidelines for occlusal treatment. Procedures performed according to the protocols outlined in this article will facilitate orthodontics and orthopedic movement and accelerate three-dimensional jaw movement by sutural distraction of basal bone.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
2/64. Severe hypodontia: diversities in manifestations.The material comprises 33 cases, 12 boys and 21 girls with 4 or more lacking teeth in the permanent dentition, randomly collected among patients referred to the Department of Pedodontics, University of Bergen. The total number of lacking teeth were 332, mean number in boys was 11.4, in girls 9.3, ranging from 4 to 24 (third molars excluded). The most prevalently lacking teeth were second premolars in both jaws, maxillary lateral incisors, mandibular central incisors and maxillary first premolars. The maxillary central incisors were the most stable teeth, lacking in only one patient. The female group was closest to this "classical" scheme by lacking teeth mostly in posterior segments. In males the anterior segments were most often afflicted. There was no significant difference between right and left sides in both sexes, but in girls the maxillary jaw was more afflicted than the mandibular jaw. The individual analyses of cases showed great diversities in the manifestation of hypodontia. Eighteen of them behaved fairly "balanced" with respect to lack of teeth in the different quadrants. Six cases were lacking most of the teeth in the maxillary jaw (total 34 maxillary teeth versus 11 mandibular). Five cases were lacking most of the teeth in the mandibular jaw (total 30 mandibular teeth versus 14 maxillary). One patient was lacking 10 of his 12 front teeth, but only 4 of his 20 posterior teeth, and one patient was lacking 12 of his 16 posterior teeth, but none of his front teeth. The author cannot offer any explanation for these strange and varying patterns of manifestations.- - - - - - - - - - ranking = 2.5keywords = jaw (Clic here for more details about this article) |
3/64. GAPO syndrome: a new case of this rare syndrome and a review of the relative importance of different phenotypic features in diagnosis.The case of GAPO syndrome reported here is the 24th recorded case, 23 cases having been published previously. The 29-year-old male under discussion presents all the typical features of the syndrome, having short stature, dysmorphic craniofacial features, total alopecia and pseudoanodontia. Orally, the erupted primary dentition was extremely worn and on radiographic examination, the second mandibular molars were found to be unerupted, together with the entire permanent dentition. cephalometry revealed the absence of facial pneumatisation, a deficient cranial base with diminished upper face height and maxillary and mandibular hypoplasia with a prognathic skeletal pattern. Histological examination of an extracted primary incisor and its surrounding root bone revealed extensive ankylosis. This paper describes in detail the clinical findings and reviews, and discusses previously published cases in relation to the present one. As with prior cases, parental consanguinity was present in the pedigree.- - - - - - - - - - ranking = 0.12932839933178keywords = relation, record (Clic here for more details about this article) |
4/64. A comparison of autotransplantation and orthodontics in a case exhibiting two ectopic upper cuspids.Bilateral severely ectopic maxillary cuspids were treated differently on each side. On one side the ectopic cuspid was moved into position orthodontically, and on the other, the ectopic cuspid was positioned by autotransplantation. The orthodontic positioning took a long time and the tooth exhibited root resorption. Treatment time for the autotransplantation positioning was far quicker, and there was no resorption nor were there any other side effects.- - - - - - - - - - ranking = 0.26480255441922keywords = bite (Clic here for more details about this article) |
5/64. Talon cusp associated with other dental anomalies--a case report.Talon cusp is an anomalous structure resembling an eagles talon which projects lingually from the cingulum area of an incisor. It is a rare anomaly which is commonly seen in maxillary incisors. This paper is a report of a case of Talon cusp associated with cross-bite and partial anodontia.- - - - - - - - - - ranking = 0.26480255441922keywords = bite (Clic here for more details about this article) |
6/64. The dentofacial manifestations of XXXXY syndrome: a case report.This paper presents a six-year-old patient with XXXXY syndrome, whose oral findings included a cleft soft palate, hyper- or meso-taurodontism in eight primary molars and in the mandibular permanent first molars, five congenitally missing premolars, and delayed development of the permanent tooth germs. The maxillary and mandibular primary central incisors were in a cross-bite relationship. Cephalometric findings showed a short ramus of the mandible and a short maxilla in the anterioposterior plane. The anteroposterior jaw relationship was in harmony. The cross-bite was considered to be due to the retroinclination of the maxillary primary incisors. This case emphasises the importance of regular dental care, and monitoring of facial growth and dental development in children with XXXXY syndrome.- - - - - - - - - - ranking = 1.2032756808999keywords = jaw, bite, relation (Clic here for more details about this article) |
7/64. A rare non-syndrome case of concomitant multiple supernumerary teeth and partial anodontia.Concomitant hypo-hyperdontia is an uncommon condition of coexistence of partial anodontia and supernumerary teeth. Its etiology is still unknown. Very few cases have been reported in the literature of this condition. Presented here is a rare and first such case of simultaneous presence of multiple supernumerary teeth and a missing tooth (canine) without any associated systemic conditions or syndromes involving both jaws.- - - - - - - - - - ranking = 0.5keywords = jaw (Clic here for more details about this article) |
8/64. Simultaneous presence of a congenitally missing premolar and supernumerary incisor in the same jaw: report of case.Supernumerary teeth and hypodontia can be regarded as opposite developmental phenomena. An eight-year-old girl presented a concomitant occurrence of a supernumerary tooth and two congenitally missing teeth. The supernumerary tooth was found in the left maxillary incisor region, while the left second premolar in the maxilla and the left lateral incisor in the mandible were congenitally missing. The supernumerary tooth showed a similar color and morphology to those of the maxilla lateral incisor, and the lateral incisor on the mesial side was diagnosed as a supernumerary tooth from dental age, eruption time, and mesiodistal crown dimension. The supernumerary incisor was guided labially to cure an anterior cross-bite, and the lateral incisor, canine, and first premolar were guided distally to compensate for the space left by the congenitally missing left second premolar.- - - - - - - - - - ranking = 2.2648025544192keywords = jaw, bite (Clic here for more details about this article) |
9/64. Oro-dental and craniofacial anomalies in leopard syndrome.'leopard syndrome' is a syndrome affecting many systems or organs. The main anomalies are summarized in the acronym LEOPARD in which each letter corresponds to the damage of a given organ. In the presented case, there are oro-dental and craniofacial anomalies. The relationship between the leopard syndrome and the given anomalies and the possibilities of the management and the follow-up of the diseased are studied. The clinical case presented is a 4-year-old boy with leopard syndrome showing retardation of dental development, delayed development and possible agenesis of permanent teeth, and craniofacial anomalies (osseous hypodevelopment). The bibliographical study shows that leopard syndrome is due to damage of the neural crest cells. Thus, the dental and craniofacial anomalies arise since neural crest cells participate in the formation of the teeth and some craniofacial bones. Therefore, dental and craniofacial anomalies might be expected in some cases of the disease. The therapeutic management of the lesions, and the follow-up of the patient would be done by a multidisciplinary team.- - - - - - - - - - ranking = 0.08683528603074keywords = relation (Clic here for more details about this article) |
10/64. Spaced dentition--open, close or redistribute?A spaced dentition can be due to various reasons such as hypodontia, tooth size discrepancy and impeded eruption. The dilemma for clinicians is whether to close, open or redistribute space. Closing space by orthodontics eliminates the need for prosthetic rehabilitation but it might compromise aesthetics and function. On the other hand, opening space is more complex and requires long-term maintenance. Based on these drawbacks, a careful occlusal analysis and an individualized treatment plan are mandatory for achieving the best result. The prognosis for closing space and substituting congenitally missing maxillary laterals with canines depends on factors such as overjet, lip support, crown colour, shape and root position. If these are unfavourable, opening space for prosthetic replacement is then preferred. Discrepancy between tooth and jaw size results either in spacing or crowding. The location of the spacing and the amount of overjet are important factors guiding the direction of treatment.- - - - - - - - - - ranking = 0.5keywords = jaw (Clic here for more details about this article) |
