Correlation of Orthodontic Treatment by Fixed or Myofunctional Appliances and Periodontitis: A Retrospective Study.

INTRODUCTION: Malocclusion plays an important role in the development of periodontitis. Thus, by treating malocclusion, a good gingival health can be achieved. This study was conducted to establish the correlation between orthodontic tooth movement and periodontitis. MATERIALS AND METHODS: This is a retrospective study conducted on 220 patients who underwent orthodontic treatment for malocclusion. They were divided into two groups: Group I patients were treated with fixed orthodontics, while group II patients received myofunctional appliances. RESULTS: The value for plaque, gingival recession, and tooth mobility significantly increased in group I patients. However, the difference was statistically nonsignificant in group II patients. CONCLUSION: The authors concluded that there is correlation between malocclusion and periodontitis. Malocclusion leads to periodontitis. CLINICAL SIGNIFICANCE: Malocclusion is the main reason for the development of poor periodontal health. Combined effort has to be played by both periodontist and orthodontist for the treatment of various orthodontic-periodontal problems.

Orthodontic treatment of a patient with unilateral orofacial muscle dysfunction: The efficacy of myofunctional therapy on the treatment outcome.

The orofacial muscle is an important factor in the harmony of the occlusion, and its dysfunction significantly influences a patient's occlusion after craniofacial growth and development. In this case report, we describe the successful orthodontic treatment of a patient with unilateral orofacial muscle dysfunction. A boy, 10 years 0 months of age, with a chief complaint of anterior open bite, was diagnosed with a Class III malocclusion with facial musculoskeletal asymmetry. His maxillomandibular relationships were unstable, and he was unable to lift the right corner of his mouth upon smiling because of weak right orofacial muscles. A satisfactory occlusion and a balanced smile were achieved after orthodontic treatment combined with orofacial myofunctional therapy, including muscle exercises. An acceptable occlusion and facial proportion were maintained after a 2-year retention period. These results suggest that orthodontic treatment with orofacial myofunctional therapy is an effective option for a patient with orofacial muscle dysfunction.

Skeletal Class III and anterior open bite treatment with different retention protocols: a report of three cases.

The treatment of skeletal class III and anterior open bite can be unstable and orthodontists frequently observe relapse. Here, we report on the management of three patients with skeletal class III profiles and open bites treated by orthodontic camouflage. Each received a retention protocol involving the use of two separate appliances during the night and day accompanied by myofunctional therapy. Long-term follow-up revealed a stable outcome.

The clinical observation describes the case of a 20-year-old woman who has consulted for aesthetic and functional reasons. She presents a skeletal class III normodivergent, an occlusal class III with a lower proalveoli quite marked. In addition, a lingual dysfunction which manifests itself by important anterior diastema and dento-dental disharmony at the upper jaw complicates the case. The undertaken therapeutic project starts with a first step of a lingual praxis rehabilitation, followed by an orthodontic step and upper lateral incisors-plasty. The purpose of those results is the evaluation of the stability two years later, which was reported positive.
