Ugly duckling stage is a self_correcting malocclusion which is seen around 8 to 11 years of age or during the eruption of canine. As the permanent maxillary canines erupt they displace the roots of maxillary lateral incisors mesially. This force transmitted to the central incisors and their roots are also displaced mesially. Thus the resultant force causes the distal divergence of the crown in an opposite direction, leading to midline spacing. This is called Ugly Duckling Stage. This condition corrects itself after the canines have erupted . The canines after eruption apply pressure on the crown of incisors there by causing them to shift back to original positions. The term ugly duckling stage indicates the unesthetic appearance of child during this stage.

Not a single factor can determine if case needs extraction or not. Firstly , proper classification of occlusion, Proper case history with extraoral and intraoral findings, Study models, Lateral ceph and opg, Everything is essential to reach a proper diagnosis , which in turn will decide the treatment planning. Ortho tips: A general guideline for extraction in treatment planning in Orthodontics . As we have discussed earlier, a single parameter cannot decide whether the case is extraction or not. But to get a general idea, we can innumerate few points for decision making. Facial esthetics and severity of crowding decide if extraction is needed or not. For eg, if nasolabial angle if straight or obtuse, extraction will only worsen the profile . Same for other facial parameter. Like, extraction are not suitable for cases having straight or concave profile. Incompetent lips are favourable for extraction. If lips are inside rickets esthetic line, then extraction should not be cnsidered. Having said this, again I want to repeat , a combination of all these factors helps to decide , what is best for the patient . Extraction in Orthodontics General guidelines about extraction based on classification of occlusion. Extraction varies case to case , but in more than 80% of cases, we follow same guidelines. Class 1 bimax and cases with severe crowding - All 4 1st premolar extraction. Class 2 div 1 - Maxillary both 1st premolar extraction. OR Upper both premolar and one lower incisor. {Central or lateral incisor.} Class 2 div 2 - Most of the time,ni extraction requires. Class 2 div 1 subdivision - Maxillary both premolar extraction and lower premolar extraction on the side of class 1. Class 2 div 2 subdivision - No extraction. Class 3 .- It is based on severerity of malocclusion. Mild cases requires one lower incisor extraction. Class 3 bimax requires all 4 premolar extraction. For severe class 3, orthognathic surgery is needed. Note - These are just to help you to get a rough idea about extraction in orthodontic. It's no way a blueprint for case management.

Having awareness about the treatment that you are looking for yourself or your child is a good thing. However with awareness sometimes you get to know few things which may be myths. So below are some of the most common orthodontics myths: Myth-1: There is no point of having braces for an adult: Some treatments take more time for an adult than they do for children because adult's facial bones are no longer growing and certain corrections may not be accomplished with braces alone. While its true that approach to crooked teeth may be different for adults compared to children, but you're never too old for orthodontic treatment. Moreover a healthy beautiful smile is equally important at the age of 40 as it is at age of 14. Nowadays there are many orthodontic treatment options available for adults. Today's braces do not draw as much attention of people as you may believe. Myth-2: The tighter, the better: Many people insist to orthodontist to keep their braces tight. People believe if braces are too tight they will get their braces off faster! Its true that braces should have certain level of force to move the teeth, but the force level which is too high can certainly damage the bone and surrounding tissues. Orthodontic treatment is an art of maintaining delicate level of force by making sure teeth do not move in the wrong direction and the force does not damage teeth bone and surrounding tissues. Myth-3: Only braces can straighten my teeth: Not necessary, with technology advancement its now possible to straighten your teeth without having to wear braces. Products such as Invisalign Clear Aligners are one of the options that offer teeth straightening without having to wear braces. However Invisalign Clear Aligners may not be the best option for fixing bite problems if there are many crooked teeth. Its best to visit for an initial consultation and let the orthodontist find-out what kind of treatment option can suit you best. Myth-4: After removing braces my teeth will stay straight forever: Getting your teeth straight with the help of braces is just half work done. After removing braces we may recommend you to wear retainers to make sure your teeth stay in place. Myth-5: Orthodontic treatment is painful: With the help of technology advancement braces have become far less irritating. Braces do not hurt at all after they are applied to teeth. In some cases patient may feel mild soreness or discomfort, which disappears after few days. Remember, "It does not have to hurt to work!" Myth-6: The length of treatment is guaranteed: An orthodontist can only do a rough estimation about length of the treatment. At the same time you cannot compare length of treatment with anyone else. This is because there are many factors affecting length of treatment such how your teeth respond to braces, breaking down of braces during the treatment, not brushing well, not coming in for regular appointments, having dense bone etc. Ortho tips: In extraoral examination, for most important factors to consider are as follows. 1. Facial profile 2. Lip competency 3. Nasolabial angle 4. Relationship of lips to Rickets esthetic line . I.e. E-line 1. Profile of the patient can be straight, convex or concave 2. Lips can be competent or incompetent. Lip incompetency may be due to : A. Proclined incisor B. Short upper lip which is less than 10mm from the base of the nose to the philtrum. C. Vertical maxillary excess 3. Nasolabial angle may be acute , obtuse or 90° 4. Lips can be outside or inside of Rickets esthetic line. All the above mentioned factors helps to determine treatment modality, and whether the case is extraction or non extraction.
