This case report describes the treatment of a case involving a skeletal Class II facial profile with a gummy smile. While treating a facial profile and a gummy smile, the outcome may not always be successful with orthodontic therapy alone. For this reason, surgical therapy is often chosen to gain an esthetic facial profile and a good smile. However, sometimes the patients reject surgical treatment and an alternative method must be considered. Skeletal anchorage systems such as miniscrews are now frequently used for correcting severe malocclusion that should be treated by surgical therapy. In this case report, we treated a skeletal Class II malocclusion with a convex profile and a gummy smile using miniscrews, which were placed in the upper posterior and anterior areas. The active treatment period was 3.5 years, and the patient's teeth continued to be stable after a retention period of 36 months. 相似文献

Orthodontics in combination with orthognathic surgery is a possibility today for correcting sagittal, vertical and transversal dysmorphosis. To do this, orthodontic preparation before surgery is necessary. In the sagittal plane, dental compensations should be removed. In the vertical plane, levelling of a severe mandibular SPEE curve should be accomplished postsurgically, and transverse coordination obtained. Orthodontic preparation is very specific to the type of dysmorphosis: class II malocclusion, class III malocclusion or in open bite. Postsurgical orthodontic treatment is used to finalize tooth alignment as in conventional orthodontics. 相似文献

This report highlights the benefits that can be achieved with the combined orthodontic and orthognathic surgical approach where the presenting malocclusion is related primarily to an underlying skeletal malrelationship. The patient experienced a dramatic improvement in her facial form and occlusion, and a reduction of her excessively "gummy smile". 相似文献

Nonextraction treatment of a severe Class II, Division 2 malocclusion is presented. Timing, sequencing of appliance therapy, and segmental arch treatment are discussed. The effects of orthodontic treatment, pubertal growth, and postpubertal growth are illustrated with different growth responses. Correction of the handicapping malocclusion was achieved by the development of arch circumference, torque, intrusion of incisors, and vertical buccal dentoalveolar development. Various subtypes of Class II, Division 2 malocclusion are presented. Pretreatment and posttreatment records are evaluated. 相似文献

Malocclusions with a hyperdivergent vertical facial pattern are often difficult to treat without a combined surgical/orthodontic approach. The aim of this article is to describe a nonsurgical approach to the treatment of a high-angle Class II malocclusion in a growing patient. Some fundamental aspects, such as correct diagnosis, treatment timing, favorable mandibular growth pattern, and patient compliance, proved to be critical to correct the severe dentoskeletal disharmony. 相似文献

AbstractThis paper describes the orthodontic treatment of two cases awarded the prize by the British Orthodontic Society for best treated cases submitted for the Membership in Orthodontics. The first case reports on the treatment of a class III malocclusion with increased vertical lower anterior facial proportions and dentoalveolar compensation that was treated with orthodontic camouflage. The second case reports on the treatment of a class II division II malocclusion with reduced vertical lower anterior facial proportions and an overbite complete to the palate, which was treated with orthodontic camouflage. 相似文献

Optimum treatment timing for orthodontic problems continues to be one of the more controversial topics in orthodontics. Especially regarding the correction of Class III malocclusion, there is little consensus as to proper timing or methods for correcting these problems. The orthopedic approach for growth modification is usually limited to children with growth remaining subjected to non hereditary pattern. If the skeletal malocclusion is within the range of an orthodontic treatment, fixed orthodontic appliances with dentoalveolar compensation mechanism can achieve a normal occlusion. Otherwise in patients with a severe skeletal discrepancy, it will be necessary to consider a combined surgical and orthodontic approach. The purpose of this study was to describe treatment planning according to the age and to the initial diagnosis. The management of skeletal Class III malocclusion is still a challenge to orthodontists especially because of relapse due to the late growth of the mandible. 相似文献

This case report describes a patient who presented with a severe class 2 skeletal discrepancy together with a Class II malocclusion and a large anterior open bite. The malocclusion and skeletal discrepancy were managed with a combination of orthodontic and orthognathic treatment. The orthognathic surgery was undertaken following orthodontic decompensation using sectional mechanics to allow a segmental bimaxillary osteotomy and genioplasty to be performed. Although the discrepancy was severe using this combination of treatment, a successful outcome, both facially and occlusally, was achieved. 相似文献

Malocclusion, with a superimposed vertical growth tendency, is often difficult to treat without a combined surgical orthodontic approach. Certain situations, however, may preclude surgery as a treatment option. The following case report demonstrates the use of orthodontic mechanotherapy alone in successfully treating a patient that exhibited a Class II Division I malocclusion with a high mandibular plane angle and vertical growth tendency. 相似文献

The cases presented in this paper share a common skeletal characteristic, hyperdivergence, a common therapeutic strategy, similar diagnostic elements, and a common choice of non-symmetrical extractions. Interceptive treatment is especially useful for this type of malocclusion to prevent deep over-bites, atypical habits, and severe malocclusion. In the Tweed-Merrifeld technique, orthodontists use careful dental, occlusal, cephalometric, and esthetic evaluations to establish an appropriate treatment plan and therapeutic strategy whose goal will be: to eliminate unhealthy compensations, re-position, if necessary, alveolar structures on basal bone, reduce anterior-posterior and vertical discrepancies, favor anterior mandibular rotation, improve facial esthetics, restore functional occlusion, and assure stability of results. Because of its consistent capability of achieving predictable resolution of the most varied and complex orthodontic disorders, the author has chosen this technique for routine use in his daily orthodontic practice. 相似文献

The article presents a case of a young female patient who sought help due to myofascial pain followed by a sudden occlusal change (anterior open bite (AOB)) that occurred shortly after the administration of a soft night guard that had been previously provided by a general dentist. Palpation of the masseter and temporal muscles elicited the presence of familiar pain. After magnetic resonance imaging of temporomandibular joints, which ruled out disc displacement, the final diagnosis was myalgia. Since the patient had myalgia and malocclusion, the therapy included treatment of both conditions. Temporomandibular disorders (TMDs) management included a combination of kinesiotherapy, pharmacotherapy, and a stabilization splint. After TMD symptoms had resolved, the patient underwent an orthodontic evaluation. Cephalometric analysis revealed skeletal class II, retrognathic face, convex profile, and normal vertical growth pattern. Orthodontic treatment included a fixed appliance with vertical intermaxillary elastics. After 19 months of treatment, both sides achieved acceptable occlusion with Class I. Since the patient had myalgia and severe malocclusion, it was important to follow a systematic diagnostic and therapeutic workflow. Although it is impossible to establish a relationship between TMD symptoms and orthodontic therapy, patients who have TMD symptoms should have their pain resolved through a conservative treatment protocol before commencement of orthodontic treatment. The beginning of orthodontic therapy comes into consideration only when the TMD pain resolves. 相似文献

Objective:To determine the prevalence of malocclusion and need for orthodontic treatment among persons with Down Syndrome (DS).Materials and Methods:Study participants were 113 persons with DS from the selected community-based rehabilitation center who fulfilled the inclusion and exclusion criteria. Ten occlusal characteristics of the Dental Aesthetic Index (DAI) were measured on study models to determine the degree of malocclusion. A single score represented the dentofacial anomalies, determined the level of severity, and determined the need for orthodontic treatment.Results:Crowding in the anterior maxillary and mandibular arch was the main malocclusion problems among the subjects with DS. Comparison between age group and genders revealed no significant differences in four categories of orthodontic treatment need (P > .05).Conclusion:Most of the subjects with DS (94; 83.2%) had severe and very severe malocclusion, which indicated a desirable and mandatory need for orthodontic treatment. 相似文献

Superior repositioning of the maxilla via maxillary ostectomy has proved to be useful method of treating patients with vertical maxillary excess. It is indicated primarily in patients with lip incompetence, excessive exposure of maxillary anterior teeth, long lower facial height, contour-deficient chin, and either Class I or Class II malocclusion. We have used this procedure as routine treatment for vertical maxillary excess over the past 5 years. Timing of the surgery is not so important in non-open-bite patients, and the procedure can be done with equal success before any orthodontic intervention, during orthodontic treatment, and following all orthodontic procedures. Timing is primarily dependent upon the orthodontist's desires. Since the surgery can produce a much simpler orthodontic problem, thus reducing treatment time and allowing a better over-all result, we recommend that it be done as early in treatment as possible. Clinically, the over-all improvement in facial appearance and the predictability and stability of the results have made this a most versatile and effective procedure when carried out with good planning, proper execution and attention to detail. 相似文献

Skeletal class III malocclusion is one of the most difficult dentofacial anomalies, characterized by deviation in the development of the mandible and maxilla in the sagittal plane, where the mandible is dominant in relation to the maxilla. In patients with class III malocclusion, anomalies in the dentoalveolar level and esthetic discrepancies are also frequent. The etiology of class III malocclusion is multifactorial due to the interaction of hereditary and environmental factors. Rehabilitation and treatment of malocclusion is one of the major goals of modern dentistry. This article presents the orthodontic‐prosthetic therapy and rehabilitation of a 45‐year‐old patient with an abnormal occlusal vertical dimension and a skeletal class III malocclusion. The patient came to the clinic complaining about degraded esthetics and disordered functions of the orofacial region (functions of eating, swallowing, speech) and also pain in the temporomandibular joint. After the diagnosis was made, the patient was first referred to orthodontic treatment with fixed orthodontic appliances (self‐ligating brackets system Rot 0.22). Upon completion of the orthodontic treatment, the patient was sent for further prosthetic treatment. Fixed prosthetic restorations were made in the upper and lower jaw, thus achieving a satisfactory result in terms of esthetics and function of the stomatognathic system. 相似文献

The case of an adult patient with a severe mandibular retrusion of the Class II, Division 2 malocclusion type has been presented. The patient's marked anteroposterior discrepancy was complicated by the severe malocclusion. The solution to this case involved presurgical orthodontic treatment to allow for surgical mandibular advancement by a modified sagittal osteotomy and postsurgical orthodontic care for alignment of the dentition. A discussion of the importance of the patient's facial growth type for stable mandibular advancement has also been presented. 相似文献

Timing of orthodontic treatment, especially for children with developing class III malocclusions, has always been somewhat controversial, and definitive treatment tends to be delayed for severe class III cases. Developing class III patients with moderate to severe anterior crossbite and deep bite may need early intervention in some selected cases. Class III malocclusion may develop in children as a result of an inherent growth abnormality, i.e. true class III malocclusion, or as a result of premature occlusal contacts causing forward functional shift of the mandible, which is known as pseudo class III malocclusion. These cases, if not treated at the initial stage of development, interfere with normal growth of the jaw bases and may result in severe facial deformities. The treatment should be carried out as early as possible for permitting normal growth of the skeletal bases. This paper deals with the selection of an appropriate appliance from the various current options available for early intervention in developing class III malocclusion through two case reports. 相似文献

Many patients seek orthodontic treatment for esthetic improvement. These patients mostly present with mal-alignment of the anterior teeth. The positive effects of orthodontic treatment on their appearance and self-esteem are easy to envision. However, does orthodontic treatment provide dental health benefits in addition to the esthetic benefits? Do malocclusions harm the periodontium? Is correcting malocclusions with orthodontic treatment beneficial for periodontal health? The purpose of this study is to present evidence available on this topic. Two systematic reviews were conducted to address these questions: does a malocclusion affect periodontal health, and does orthodontic treatment affect periodontal health? Inclusion and exclusion criteria were established for both reviews, and an electronic search and a hand search were conducted. Several papers were included in both reviews, but the overall quality of the studies was weak. The first review found a correlation between the presence of a malocclusion and periodontal disease. Subjects with greater malocclusion have more severe periodontal disease. This may be dependent on oral health status. One should keep in mind that an association does not necessarily mean causation. The second review identified an absence of reliable evidence on the effects of orthodontic treatment on periodontal health. The existing low-quality evidence suggests that orthodontic therapy results in small detrimental effects to the periodontium. The results of both reviews do not warrant recommendation for orthodontic treatment to prevent future periodontal problems, except for specific unusual malocclusions. 相似文献
