"Aim: The aim of our study was to identify differences in the use of light and heavy intrusive forces on the alveolar ridge morphology adjacent to the intruded teeth. Material and methods: The sample included 17 patients, we worked with 34 premolars. Light intrusive force (LF) 50 cN (g) and heavy force (HF) 150 cN (g) was used on contra-lateral teeth. The force was activated in one-month intervals. 3 clinical parameters and 7 CBCT parameters were evaluated at time before the experiment (T0) and after 6-month intrusion (T1).. The differences were statistically processed with two-sample t-test. Results: The extent of intrusion was significantly greater during heavy force activation (p=0.0001); it was almost 3 x higher in comparison with light force (4.64 mm compared to 1.53 mm). After the application of orthodontic force the attachment moved apically (%22bone sulcus%22 - BS) and cemento-enamel junction to peak of alveolar bone - CEA). This change was significantly higher in HF (p=0.0001; p=0.001). Gingival sulcus deepened (p=0.0001); it was accompanied with the reduced clinical crown of the tooth (p=0.004). Conclusion: Heavy forces lead to a more extensive intrusion accompanied with a more profound remodeling of alveolar ridge, deeper gingival sulcus, and reduced clinical tooth crown. In case a more extensive tooth intrusion is required (e.g. during the correction of molar supraocclusion), heavier force application should be recommended in spite of some adverse effects, e.g. deeper gingival sulcus, increased tooth root apex resorption."@en . .
