| Abstract |
|
Twin blocks are bite-blocks that effectively modify the occlusal inclined plane to induce favorably directed occlusal forces by causing a functional mandibular displacement. One of the advantage is that full-time wear can be possible because of less interference with normal function such as eating and speaking. So rapid correction of malocclusion is expected. Reverse twin block appliance is modification for correction of class III malocclusion with sagittal component. For increased growth stimulation effort on premaxilla, lip pads can be added. But with lip pads, patients are incapable of full-time wear especially during mealtime. So, removable lip pads can be used for stimulation of growth on premaxilla without any restriction of function. The advantages of the reverse twin block appliance with removable lip pads are: 1. Full-time wear is possible (including mealtime). 2. Patients' cooperation and adaptation is excellent. 3. There is no period of dual bite. 4. Orthopedic correction is achieved by multiple modes, shortening the treatment time. The applied case shows that the reverse twin block appliance with removable lip pads is effective for treatment of class III malocclusion and can shorten the time of treatment. |
