Megahed's Magnetic Appliance (MMA) for Cessation of Thumb Sucking Habit| Chapter 9 | Disease and Health Research: New Insights Vol. 2

 

Management of thumb-sucking habit is being performed by many habit-breaking appliances that are associated with speech, chewing, and esthetic problems due to their bulky metal components. These drawbacks may affect patient compliance and call for a new trial with a different habit-breaking appliance that can efficiently break the habit with better patient acceptance.

 

The case discussed in this chapter has undergone comprehensive diagnosis where diagnostic records were taken (Extra-oral and intra-oral photographs, lateral cephalometric and panoramic radiographs, and study models) along with impression for appliance fabrication. When received from the laboratory, the appliances were disinfected, fitted then cemented and adjusted in the patient’s mouth and thumb. The patient and his parent were enlightened about the advantages of the appliances, which entailed cessation of thumb sucking habit thus allowing tooth eruption and open bite closure, and giving them the instructions at the time of appliance insertion. A questionnaire to test patient compliance was given to the parents every follow-up. Treatment was consummated once the child ended 12 months of follow-up regardless of the fact that it could be achieved.

 

Treatment effects were evaluated by comparing pre and post-treatment records along with the questionnaire answers. The report showed the patient was compliant with the appliance, with a significant increase in overbite and the maxillary inter canine width. This might be the result of cessation of thumb pressure on the palate. It also showed a significant reduction in lower anterior facial height. The maxillary incisors had been uprighted. The interlabial gap greatly reduced after treatment while the nasolabial angle recorded no significant change. It was concluded that the magnetic habit breaker was effective in stopping the habit and helping bite closure due to the appliance's dual effect and good patient acceptance. The anterior open bite was significantly improved with the correction of the maxillary inter-canine width.

An Innovative Approach of Skeletal Maxillary Bilateral Posterior Crossbite Correction with Decortication and Bone Autograft Augmentation | Chapter 11 | Challenges in Disease and Health Research Vol. 4

 Context: Deliberate periodontium damage caused by either corticotomy, piezocision or microosteoperforation causes increased remodelling of the alveolar bone due to regional acceleratory phenomena leading to rapid movement of the tooth. Periodontal bone graft augmentation provides the periodontium with structural integrity, reducing tell-tale relapse incidence. The procedures advocated for the accelerated correction of the skeletal maxillary bilateral posterior crossbite and open bite malocclusion were selective decortication and bone autograft augmentation in the case mentioned. A -18-year-old female patient with moderate Class III skeletal malocclusion, increased bimaxillary dento-alveolar protrusion, anterior open bite, forward tongue position, and maxillary bilateral posterior crossbite imbricated and rotated mandibular incisors. A protocol for non-extraction care has been recommended. Methods: Full thickness mucoperiosteal flaps were mirrored in the maxillary oral regions one week after strapping of the pre-adjusted edgewise appliance, MBT prescription (0.022 x 0.028-inch slot) and Hyrax unit. With surgical perforations, decortication was performed and supplemented with bone autograft taken from the patient's symphyseal area. The activation of the Hyrax system two weeks later was conducted twice daily, with the other orthodontic changes conducted fortnightly before completion of treatment. Results: 2.5 months of accelerated correction of the skeletal maxillary bilateral posterior crossbite and 7 months of care of full malocclusion were achieved. Conclusion: The accelerated malocclusion correction could be attributed to the regional acceleration phenomenon induced by the deliberate surgical insult induced by the decortication procedure and the stable outcome thus observed was attributed to the bone autograft periodontal augmentation. In one-third to one-fourth of the treatment necessary for traditional malocclusion correction, the selective decortication procedure accelerated the correction of the maxillary bilateral posterior crossbite and open bite malocclusion and the augmented bone autograft provided excellent bone volume for the much needed post-treatment stability results in these cases.
