[Jaw bone orthodontics in dogs].

Orthodontics is the branch of dentistry that is concerned with the diagnosis and treatment of malocclusion and related skeletal disorders. The different breeds of dogs show marked variations in occlusion based on the skeletal morphology of the breed. Any malocclusion that is considered genetic, or is suspected of being genetic, should be treated orthodontically, unless the malocclusion is causing, or may cause, an oral problem. If breeding pets have a genetic malocclusion, orthodontic corrective procedures are considered unethical and should only be performed if the pet is neutered, or if you are convinced that the owner does not plan on breeding or showing. Any malocclusion that is considered acquired can be corrected orthodontically. The author described three clinical cases of acquired malocclusion. These cases treat of caudally inclined teeth (retrusion), rostrally inclined teeth (protrusion) and lingually displaced teeth (oral). The treatments were done with expansion screws, elastic power chains, buttons, hooks and brackets.

[Spontaneous corrections and orthodontic treatment].

Spontaneous corrections in orthodontic anomalies can sometimes be expected, when all hindrances are eliminated, and the relevant teeth are given every freedom. Although there seems to be no exact explanation for the corrections some speculations are presented. Advantages and disadvantages are discussed.

A therapeutic concept for the combined orthodontic surgical correction of angle Class II deformities with short-face syndrome: Surgical lengthening of the lower face.

In today's society not only facial esthetics have become important, but also the information on ways to correct adult orthodontic problems is readily available. Subsequently, increasing number of adults seek orthodontic treatment merely to change their facial appearance. In general, these adult patients exhibit such a severe skeletal deformity that it is noticeable even by non-experts. The nature of these adult deformities is such that the only promising treatment is the combined orthodontic-surgical approach. A stable and functional occlusion with a physiologic position for the condyle is the common goal of orthodontic treatment. In patients with skeletal deformities, however, improvement of facial esthetics takes paramount importance. They judge the success of treatment by extraoral appearance. Accordingly, the clinician must assess both the dental and facial appearance, and then inform the patient of different treatment possibilities. In this scenario, patient's input into the decision making process is critical for a mutually satisfactory result. This clinical report describes a concept of systematic approach to treatment of Class II deformities with skeletal deep bite and short lower face (short-face syndrome). This approach emphasizes the soft tissue analysis.

[Case report: skeletal Class III correction by orthodontic means].

Skeletal Class III therapy of the two siblings with a protraction headgear was reported. The treatment result indicated that skeletal and dental malocclusion could be achieved by redirection of maxillary and mandibular growth with force system comprising 400 grams maxillary protraction and 1000 grams mandibular retraction when the treatment was performed at the appropriate time.

Case report: nonsurgical treatment of an adult with severe anterior open bite.

A malocclusion characterized by open bite and vertical maxillary excess can be one of the most difficult problems to correct through orthodontic treatment because of the difficulty in permanently changing the morphological disharmony and/or functional disorder associated with open bite. However, in some patients with less severe skeletal impairment it may be possible to orthodontically correct the occlusal disharmony so that the new relationship of the dental arches becomes compatible with normal function of the oral environment. Stability may be enhanced if mechanics are used which do not extrude posterior teeth.

A longitudinal study on malocclusion in relation to signs and symptoms of cranio-mandibular disorders in children and adolescents.

Two-hundred-and-thirty-eight subjects in three different age-groups (7, 11, and 15 years) were followed over a period of 4-5 years in respect of morphological malocclusions, and signs and symptoms of functional disturbances. About half of the 7-year-olds had at least one of the morphological malocclusions registered while the corresponding figure was 38 per cent at the age of 20. Some subjects had received corrective orthodontic treatment. When compared with subjects without such treatment, there were no differences in prevalences of occlusal interferences, nor in signs or symptoms of craniomandibular disorders (CMD). The associations between CMD and different morphological malocclusions were low. Nevertheless, some malocclusions were found to be more important than others. In a long-term perspective cross-bite, both uni- and bilateral, anterior open bite, post-, and prenormal occlusion had some association with the development of CMD.

[Long-term observation of two post-treatment cases with an impacted maxillary central incisor corrected by orthodontic treatment].

UNLABELLED: This article describes long-term observation of two post treatment cases with an impacted maxillary central incisor corrected by orthodontic treatment. [Case 1] Age at first examination: 11 years and 1 month. Chief complaint: Retarded eruption of a maxillary right incisor and crowding of teeth. DIAGNOSIS: No skeletal problems were identified. Crown axis inclination of the impacted tooth showed 104.0 degrees. Root axis inclination showed 87.0 degrees. Treatment plan: [formula; see text] extraction, traction of the maxillary right incisor, edgewise method. Treatment time: 4 years and 3 months. [Case 2] Age at first examination: 8 years and 8 months. Chief complaint: Retarded eruption of a maxillary left incisor. DIAGNOSIS: No skeletal problems were identified. Crown axis inclination of the impacted tooth showed 112.0 degrees. Root axis inclination showed 88.0 degrees. Treatment plan: Traction of maxillary left incisor, edgewise method. Treatment time: 5 years and 6 months. The findings were as follows; 1) When the active treatment was finished, no pulp necrosis nor any resorption of root or alveolar bone was found in the two cases. 2) At present, the crown axis inclination is restored to normal in both cases. 3) The impacted maxillary central incisors were treated to the normal position in the dental archs, and the condition and the tissues around are good. The foregoing results, we are sure, can be an important traction of the impacted maxillary central incisor.

The reassertion of latent growth patterns following orthodontic treatment.

This study reports on evaluation of the occlusion in 16 young adults who had been treated orthodontically an average of 10 years previously. Cases were from among dental students who, we assume, have high dental "IQs" and greater than average concern for stability of their orthodontic correction. Relapse of the orthodontic correction was substantial; both dental and skeletal dimensions relapsed--returned toward pretreatment conditions--to statistically and clinically obvious extents. Relapse is greater here than some other studies because of our longer recall period. Results focus attention on the importance of prolonged posttreatment retention and greater awareness on the patient's part of the role of posttreatment facial growth on relapse from adolescence into adulthood.
