ABSTRACT
Objective To compare difference of clinical effect of reformed interocclusal lip arch appliance and conventional moved maxillary bite plate appliance in the interceptive orthodontics in the treatment of deciduous anterior crossbite .To search an appro-priate interceptive orthodontics treatment of deciduous anterior crossbite .Methods 50 cases of deciduous anterior crossbite were randomly divided into 2 groups(25 cases in each group) .The improvement group underwent a modified appliance therapy ,and the control group were treated with conventional bite appliance ,then we compared the clinical efficacy of the two groups .Results All the cases with the deciduous anterior crossbite were cured .After treatment ,the maxillary anterior teeth and soft tissue profile of all the patients were improved .In the improvement group the changes of the mandible ,the mandibular anterior teeth ,and the concave profile improving have more significant efficiency than those in the control group .Conclusion Both kinds of appliance could cure the deciduous anterior crossbite .The reformed interocclusal lip arch appliance has both the mechanical and functional effects and be-fits in those overbite cases ,it can be an effective interceptive treatment of children with anterior crossbite .The modified appliance group can get more harmonized profile .
ABSTRACT
Determinados aspectos da má oclusão, particularmente a mordida profunda, podem ser relacionados com a saúde do periodonto e das articulações temporomandibulares (ATM). Na Ortodontia, a mordida profunda foi considerada sempre como uma anomalia difícil de corrigir, mas também como o primeiro passo para poder prosseguir o tratamento ortodôntico. Um relato de caso de mordida profunda e mordida cruzada do incisivo lateral esquerdo superior permanente em uma má oclusão em dentição permanente classe I ilustra os princípios de tratamento do caso. A redução da mordida profunda utilizando placa da mordida (Equi-Plan) mostrou-se eficiente em um curto período de tempo (4 meses). O padrão mesofacial do paciente favoreceu o tratamento rápido da mordida profunda, da mesma maneira que um tipo dolicofacial é também propício pelo fato de o padrão de crescimento facial vertical ser mais favorável. No contraste, o tipo braquifacial exige mais tempo na hora de tratar a mordida profunda
Certain aspects of malocclusion, particularly deep bite, can be related to periodontal pathology and the healthy of temporomandibular joints (TMJ). In orthodontics, deep bite has always been considered as a difficult anomaly to correct, but also as the one most hindering to solving the problems resulting from other associated malpositions. A case report of deep bite and crossed bite of permanent upper left lateral incisor in a Class I malocclusion and permanent dentition illustrates the principles of case management. The reduction of deep bite using bite plate (Equi-Plan) showed quick and short time in permanent dentition (within 4 months). The mesofacial type of the patient favored the fast treatment of the deep bite, in the same way that a dolicofacial type also is favorable because of the facial vertical growth pattern. In contrast, the braquifacial type demands greater time to treat the deep bite

Objective: To study the effects of dental treatment and psychological treatment on daytime brycomania. Methods: 16 patients with daytime brycomania were treated with a series of measures, including eliminating dental nidi, application of bite plate on the front teeth so as to make barriers to abrasion information coming into the center occlusions, and administering medicine with psychological and mental treatment. Follow up was conducted for 6 months.Results: The symptom was relieved after one to two- week treatment; complete recover was achieved in all patients in 2 months and no recurrence was observed in 6 months.Conclusion: The study shows emotional and psychical disorders may be factors for daytime brycomania, psychological treatment is an important part for cure.
