Introduction: Literature revealed many studies were concerned with the ideal timing of skeletal discrepancies treatment regardless the type of appliance used. Aim: This study aimed to investigate perspective of orthodontists toward ideal timing for different treatment procedures with functional appliances and explore their association with the demographic background in Saudi-based offices. Materials and methods: In this observational analytical cross-sectional study a web-based questionnaire was distributed among members of the Saudi Orthodontic Society. Questionnaire involved background questions and closed-ended questions regarding timing of treatment, protocol of approaching, and length of treatment with functional appliances. Data analyzed in frequency tables and the use of association tests with significant level of p<0.05. Results: One hundred and four orthodontists (65% males, 35% females) completed the distributed questionnaire. Over 50% of orthodontists preferred to align the dentition after functional treatment. Majority (81.7%) preferred functional treatment of Class II deformities at the stage of late mixed dentition. Orthodontists were about equally divided in their management in terms of the phases of Class II treatment. Orthodontists revealed a high preference rate for early intervention by functional appliances during both stages of deciduous and early mixed dentition (81.8%). Accordingly, their treatment was usually pursued in two phases. The length of treatment with functional appliances in Class II cases was mainly preferred in the range of 7 to 12 months (61.5%) while in Class III a dominant preference for the period of 7 to 18 months of treatment (74%). Conclusion: Orthodontists’ training background was strongly associated with many treatment decisions using functional appliances especially in management of Class II cases.
