Abstract
Aim and Objectives
- To determine the soft tissue changes between the two treatment groups, ,extraction and non-extraction, equally susceptible to both treatment options. s
- To compare the changes taking place in the soft tissue variables from one group to another using cephalometric analysis
Materials and Methods
- The pretreatment and postreatment cephalograms of the class I borderline sample (50 patients, 25 of the patients were treated with premolar extraction and 25were treated without extraction)
- The pretreatment and postreatment cephalograms of all subjects were recorded and subjected to cephalomeric analysis
Results: Both groups, showed retraction of upper lip in postreatment cephalograms, whereas non extraction group showed protraction of lower lip in postreatment cephalograms.
- With regard to upper lip thickness, the difference in increase between both the groups was significant
- Significant differences (p < 0.01) regarding upper and lower lip protrusion, upper lip thickness (p < 0.05) and the nasolabial angle (p < 0.01) occurred after treatment.
Conclusion
- Class I borderline malocclusions cases treated with premolar extraction resulted significant soft tissue changes in relation to the upper and lower lip position, thickness and nasolabial angle
- Class I borderline malocclusion cases treated with non-extraction led to significant upper lip retraction and lower lip protraction.
Keywords: Borderline Class I, Soft tissue changes, Extraction vs non-extraction
