How does WonderSmile differ from other clear aligners in Singapore?

A single jaw surgery means only one jaw is manipulated during the surgery,this could be either the upper jaw (maxilla), or the lower jaw (mandible). While a double jaw surgery involves both the upper and lower jaw. The indication for either a single jaw or a double jaw will depend on each individual's case needs. If the jaw malposition involves both jaws, then a double jaw surgery is usually indicated. Likewise if the jaw malposition involves only 1 jaw then a single jaw surgery is more appropriate.

Thank you for your question and for including pictures of your smile. It appears to me that you may have had prior braces treatment with conventional braces and some of the teeth may have shifted such as the lower front teeth and the upper lateral incisors. The uploaded photo quality is not clear but there appears to be some white spot lesions or discolouration on your front teeth that could happen when oral hygiene and diet were not optimal during braces treatment. However the quality of the uploaded photo is a bit pixelated and I cannot be completely certain of this.
