Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 10
Abstract
Introduction: Facial appearance plays an important role when planning orthodontic treatment. The major issue involved in the extraction vs. non-extraction decision is its effect on the soft-tissue profile. The objective of this cross-sectional study was to determine the ratio between extraction and non-extraction treatment protocols. More over whether such decisions were based on soft tissue profile or severe arch length discrepancy in border line case at Department of Orthodontics, University Dental Clinical Centre "St. Pantelejmon" - Skopje, Macedonia. Material and Methods: One hundred and fifteen patients were randomly selected from the diagnostic database fulfilling the inclusion criteria. These records included history, lateral cephalogram and casts for each patient. Results: 39.1% of the total sample was treated with extraction protocol where as 60.9% was treated nonextraction. Out of total extraction cases, 69.8% extraction decisions were carried out on the basis of profile and 30.2% on arch length discrepancy as a predominant factor. Profile based distribution of the sample were; 55.5% convex, 43.5% straight and 1% with concave profiles. Conclusion: Most of the patients having convex and straight profile and more than half of the extraction decisions were based on profile. Arch length discrepancy was the second most important decision influencing extraction protocol decision. A borderline case with pre-treatment lip protrusion may be better served with extraction. Hence in accordance to the „soft tissue paradigm‟ such a decision during the treatment planning should be paramount in making treatment decisions. Profile based treatment planning leads to better treatment results.
