Scientific title | |
Study objectives | To evaluate the clinical effectiveness of the mid-sagittal implant as a method of preventing unwanted tooth movement (anchorage) during orthodontic treatment. The anchorage offered by implants will be compared with that from conventional orthodontic anchorage reinforcement techniques. |
Ethics approval(s) | Added July 2008: Ethical approval for this study was obtained from North Derbyshire Health and South Sheffield Local Research Ethics committees. |
Health condition(s) or problem(s) studied | Oral Health: Orthodontics |
Intervention | The anchorage offered by implants will be compared with that from conventional orthodontic anchorage reinforcement techniques. |
Intervention type | Other |
Primary outcome measure | Tooth movement. The difference in the mesial drift of the buccal teeth to be calculated: a. Relative to the cranial base using the Pitchfork analysis (Luecke and Johnston, 1992; Johnston, 1996) on the start and finish lateral cephalometric radiograph b. Relative to the palatal rugae, from the start and finish study models (Hoggan and Sadowsky, 2001) |
Secondary outcome measures | 1. Implant stability, discomfort and any signs of inflammation of the peri-implant tissues will be recorded with percussion tests using a Resonance Frequency Analyser (Meredith, 1998) and standard periodontal indices 2. Patient acceptability, compliance and discomfort measured using a questionnaire 3. Treatment outcome measured with the Peer Assessment Rating (PAR) index on the pre- and post-treatment study models |
