Menkes disease: report of two cases.

Menkes disease is a rare, autosomal recessive disorder characterized by neuronal degeneration, abnormal hair, malformed connective tissue, mental retardation, and a life span of three years. Previously reported dental findings include a high arched palate, delayed eruption of secondary dentition, and open bite. The case of twin seven-year-old males with Menkes disease is presented, along with previously unreported dental findings of spindle-shaped root resorption patterns on the primary maxillary central and lateral incisors.

Treatment of severe mandibular prognathism in combination with maxillary hypoplasia: case report.

We performed a Le Fort I osteotomy and sagittal split ramus osteotomy (Obwegeser-Dal Pont) combined with mandibular anterior segmental osteotomy without tooth extraction for a patient with severe mandibular prognathism accompanied by a hypoplastic maxilla, anterior open bite and normal anterior mandibular vertical dimension. The results of facial appearance and occlusion were excellent. This combined surgical method appears to be satisfactory for treating severe mandibular prognathism with hypoplastic maxilla.

Bimaxillary osteotomy in a female patient with hemophilia A.

We report here a case of a 22-year-old female patient with hemophilia A who had a bimaxillary osteotomy operation. Adequate replacement of Factor VIII and DDAVP(1 deamino-8-D-arginine vasopressin) led to the achievement of hemostasis during and after the surgery. Le Fort I maxillary osteotomy and mandibular sagittal split osteotomies were done to correct the facial profile of this hemophiliac patient with a class III malocclusion and posterior open-bite deformity. Careful preoperative evaluation and close cooperation with the hematologist are required if surgery is to be successful. The operation was uneventful and no postoperative complication was observed.

Treatment of occlusal plane canting using miniscrew anchorage.

Two patient therapies introduce the use of miniscrew anchorage in adult patients for the correction of mild to moderate occlusal plane canting without severe facial asymmetries. A miniscrew implanted in the infrazygomatic buttress was used as anchorage for intruding the overerupted maxillary quadrant. As unilateral intrusion of maxillary posterior teeth will develop a posterior unilateral open bite, box elastics were subsequently used to extrude the opposing teeth in the mandibular arch. These treatments show that miniscrew anchorage offers a simple, efficient method of correcting occlusal plane canting and mild facial asymmetries.

Osteoarthritis of the temporomandibular joint in an adult patient with Hashimoto thyroiditis: case report.

This case report documents the treatment of a female patient, 37 years 6 months of age, with a Class II open bite malocclusion with severe osteoarthritis of the temporomandibular joint associated with Hashimoto disease, a chronic inflammatory disease of the thyroid in which autoimmune factors play a prominent role. The simultaneous treatment of both pathologies (malocclusion and thyroiditis) led to the cessation of pain and dysfunctional symptoms in both temporomandibular joints.

Developmental occlusion, orthodontic interventions, and orthognathic surgery for adolescents.

This article addresses issues in orthodontics such as timing of treatment, expansion in the absence of a posterior crossbite, serial ex-tractions, treatment of Class II and III malocclusions, treatment of open bites, extraction versus nonextraction, preservation of E-space to resolve crowding, orthodontics and temporomandibular disorders, orthognathic surgery, and current trends in orthodontics. Although much information is presented on these topics, many controversies still exist. When more data from evidence-based systematic reviews become available, more predictable and standardized orthodontic treatments may develop.

An application of a splint purposeful resin-bonded fixed partial denture after orthodontic treatment: a case report.

An adult male patient who had lost his maxillary left central incisor seven years ago in a traffic accident presented with a chief complaint about his unaesthetic appearance associated with the loss of his maxillary left central incisor space, a Class III molar occlusion, and an anterior open bite malocclusion due to tongue-thrust swallowing. Fixed orthodontic treatment was rendered following fan-type expansion of the maxilla. A Maryland bridge as a minimally invasive dentistry approach was used as a retention appliance and the patient's aesthetic appearance was restored.

Oral appliance management of obstructive sleep apnea: a case report.

Obstructive sleep apnea (OSA) and snoring are common related conditions with major health and social implications. OSA is a progressive disease with symptoms of daytime sleepiness and chronic cardiovascular morbidity A mandibular advancement oral appliance is the only nonsurgical management modality available if continuous positive airway pressure (CPAP) cannot be tolerated. A patient who had been diagnosed with OSA was successfully treated but developed a posterior open bite and symptomatic temporomandibular joints (TMJ). An integrated approach to managing his OSA and TMJ conditions enabled him to have a comfortable and stable bite and to continue using his obstructive sleep apnea appliance. Management of OSA with an oral appliance should be handled by a dentist who is trained and experienced in the overall care of oral health, temporomandibular joints, dental occlusion, and associated structures. A team approach starting with the diagnosis of OSA by a physician and management by a dentist is described.

Retreatment of a patient who presented with condylar resorption.

This case report describes the retreatment of a patient whose initial nonextraction treatment several years earlier had been unsuccessful. When she sought new treatment, she had an open bite, proclined incisors, and severe temporomandibular joint derangement with almost complete resorption of the condyles. The new treatment, which included extractions and surgery, gave her balanced and harmonious facial proportions, a Class I occlusion with normal overjet and overbite, and a healthy dentition. There was no further loss of condylar tissue and the temporomandibular joints were asymptomatic.

Enamel dysplasia with odontogenic fibroma-like hamartomas: review of the literature and report of a case.

This article reports on a case presenting with a rare syndrome characterized by enamel dysplasia and multiple unerupted teeth with large solid fibrous pericoronal lesions manifesting with odontogenic fibroma-like features. Our case shows in addition to these findings an anterior open bite malocclusion and gingival overgrowths. These overgrowths exhibit the microscopic features of the multiple pericoronal odontogenic fibroma-like lesions that appear to be the hallmark of this syndrome. This unusual case brings the total number documented in the literature to 5, all of which were reported from South Africa.

Bilateral vertical-oblique osteotomy of ramus (external approach) for treatment of a long-standing dislocation of the temporomandibular joint: A case report.

A case of long-standing, bilateral dislocation of the temporomandibular joint characterized by anterior open bite, and an inability to close the mouth is reported. A number of conventional modalities were tried unsuccessfully to reduce the dislocated condyle. Subsequently, the patient was successfully treated with bilateral vertical-oblique osteotomy of ramus (external approach) without using internal fixation. This modality resulted in achieving occlusion and a good range of mandibular movement postoperatively.

Three-part bi-maxillary osteotomy: a case report involving resorbable plates.

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.

Seckel syndrome: report of a case.

An interesting case of a seven years old boy with a combination of clinical, genetic, radiological, pathologic and dental findings is presented in view of Seckel syndrome literature. General appearance of the patient was characterized by small forehead, posteriorly slanted ears, slightly beaked nose, midfacial hypoplasia very stunted stature with microcephaly. He had borderline mental retardation with normal motor development. Class II dentoskeletal pattern with mild overjet and open bite, congenitally missing permanent teeth, microdontia, enamel hypoplasia, taurodontism and dentinal dysplasia was observed according to the clinical and radiographic examination. In conclusion, Seckel syndrome is not encountered routinely in dental clinics, this case illustrates the importance of dental care in such a rare condition.

Comparison between the opinions of Tanzanian parents and their children on dental attractiveness.

The objective was to investigate the opinion of Tanzanian parents on dental attractiveness and to compare their opinion with that of their children. A prestructured questionnaire with 18 intraoral frontal photographs was given to 286 parents and their children aged 9-18 years. The photographs represented various types of occlusion traits, with the first 10 intraoral photographs representing grade 1-10 of the aesthetic component (AC) of the index of orthodontic treatment need, and the remaining eight photographs were added to represent malocclusions that are often seen in Tanzania. Basic statistical techniques were used to analyze the data. Photographs showing severe deviations were perceived by both children and parents as the most unattractive. The opinion was significantly correlated with children's age (P = .02) and sex (P < .0005), with older girls tending to dislike photographs showing severe deviations the most. The mean of the opinion for the photographs showing some spacing with overbite < or = 2 mm or open bite and overbite > 2 mm fell in the middle of the scale, with a tendency toward unattractiveness. Photographs matching 8-10 on the AC scale were perceived as the most unattractive, indicating what could be a lay person's priority when considering an orthodontic treatment policy in Tanzania.

Temporomandibular joint and masticatory muscle involvement in myotonic dystrophy: a study by magnetic resonance imaging.

OBJECTIVE: The purpose of this study was to evaluate the masticatory muscles and the temporomandibular joint (TMJ) by magnetic resonance imaging (MRI) in myotonic dystrophy (MD) patients. STUDY DESIGN: MRI of the masticatory muscles and TMJ was performed in 15 MD patients, 11 male and 4 female, aged 16 to 53 years (mean, 31 years). Many of them had dental malocclusion, especially Angle class III and anterior open bite, and 3 complained of recurrent TMJ dislocation. TMJ and masticatory muscle pain was not observed, and joint sounds were noted in only 1 patient. RESULTS: The analysis of MRI scans showed masticatory muscle involvement in 13 patients (86.6%). In 11, the involvement was moderate to intense. The main abnormalities observed were increased intramuscular tissue signal on T1 (fatty infiltration) and volumetric reduction of muscles. Regarding the TMJ, articular disk displacement was seen in only 1 patient, but abnormalities of disk shape were common. Mild bone abnormalities were frequently observed, including changes of shape and contour of bone surface, and sclerosis of bone marrow. In 4 patients the condyle moved anterior to the eminence with the mouth opened fully (condylar hyperexcursion). CONCLUSIONS: This study shows that masticatory muscles are frequently and intensively affected in MD patients. Bone changes are the most consistent abnormalities observed in the TMJ. It is possible that remodeling is caused by biomechanical changes in the jaw as a result of masticatory muscle involvement.

Are there any complications with bioabsorbable fixation devices? A 10 year review in orthognathic surgery.

Bioabsorbable fixation devices have been used in our departments between November 1991 and November 2001 in orthognathic surgery. The aim of this retrospective study was to assess all complications experienced during this time period, when we have operated 163 patients who have undergone 329 orthognathic osteotomies fixated with bioresorbable devices. No postoperative intermaxillary fixation was used. Light guiding elastics were used for 5 to 7 weeks. Patients' acceptance was generally excellent and very few complications occurred during this follow-up of 10 years. The complications were minor and did not affect the end results of the operations. Minor complications occurred in 14 patients (8.6%). Only one patient (0.6%) had a postoperative infection with elevated infection parameters. The other minor complications consisted mainly of dehiscence of the wound and plate exposure together with granulation tissue in the operation field. The rest of the complications occurred in the beginning of our study, when large screw heads on top of the bone irritated the patient and had to be removed. Insufficient fixation resulted in open bite in three patients (1.8%) in the beginning of the trial use of new devices, which no longer are used. Based on our experience, bioresorbable devices are safe to be used in orthognathic procedures. However, there is a learning curve, as there is with all new methods introduced.

Amelogenesis imperfecta: the multidisciplinary approach. A case report.

Amelogenesis imperfecta is a hereditary developmental disorder of the dental enamel, in both primary and permanent dentition. The main clinical characteristics are extensive loss of tooth tissue, poor esthetics, and tooth sensitivity. Transmission of the gene takes place by either autosomal, dominant X-linked, or recessive modes. This clinical report describes a treatment sequence based on a multidisciplinary approach. A 21-year-old girl with hypoplastic amelogenesis imperfecta was referred to the Ege University School of Dentistry clinic. She was concerned about the poor appearance and sensitivity of her teeth. The patient presented with an anterior open bite, although orthodontic treatment had been completed previously. Periodontal gingivectomy of her posterior teeth followed by endodontic treatment where indicated was proposed. The prosthodontic treatment consisted of metal ceramic fixed partial dentures of precious alloy. At the end of treatment, function and esthetics were improved to a level acceptable to both the patient and the dental team.

Dual segmental distraction osteogenesis of the midface in a patient with Apert syndrome.

OBJECTIVE: To present orthodontic treatment combined with dual segmental distraction osteogenesis in a patient with Apert syndrome. PATIENT: A 15-year-old boy exhibited severe midfacial hypoplasia with retruded and hypoplastic maxilla and anterior open bite. The patient was treated with a rigid external distraction II system for distraction osteogenesis, a preadjusted edgewise appliance, and a modified maxillary protraction headgear. The concave profile with midfacial hypoplasia was improved. A tight occlusal relationship between maxillary and mandibular teeth was achieved. Postoperative treatment results have been stable for 1 year.
