    A Female patient come with the chief complain of spacing in upper teeth. The extraoral examination reveals europrosopic faceform, brachycephalic headform, convex profile, competent lips, acute nasolabial angle. The intraoral examination shows Class I molar relation, Class I canine relation  with spacing in upper arch & crowding in lower anterior teeth. Diagnosis is Angle's Class I malocclusion with anterior spacing.and lower crowding.

Treatment Objectives: 
  • To close space in upper teeth

Treatment Progress: 

    The orthodontic treatment is started with banding and bonding in upper and lower arches with standard 0.022 inch MBT preadjusted edgewise appliance. The initial leveling and alignment process is started on 0.014 nickel‑titanium (NiTi) arch wire. The sequential change of arch wires are 0.016 nickel‑titanium (NiTi), 0.017 x 0.025 NiTi, 0.019 x 0.025 NiTi, 0.019 x 0.025 SS. After the leveling & alignment is completed, space closure is performed. Finishing & detailing is done on 0.019 x 0.025 braided SS wire by settling elastics. The overall treatment duration is approximate 1 year. After removal of orthodontic appliance, lingual fixed retainer and removable essix retainers are given.

What is the right age of Orthodontic Treatment?

The answer is: it depends!  There are several factors that should taken into consideration before making a decision to start orthodontic treatment.  But before we get into that, there are three important things you should know: 1. Permanent teeth start growing around 6 years of age The first permanent teeth to grow are the first molars which grow behind the very last milk molar tooth. Central incisors (front teeth) are the first teeth to replace the milk teeth. 2. It takes around 5-6 years to complete the transition from milk teeth to permanent teeth Most children get their full set of permanent teeth around age 12-13 years. 3. A child's age is not always an accurate indicator of dental development This means that some children develop and grow their teeth quickly while others do not.

Dental implants are artificial roots used to support replacement teeth. Crowns and Caps:      A crown or cap is a cover that fits over a tooth that has been damaged by decay, broken, badly stained or mis-shaped. It is prepared by your dentist, and usually requires more than one visit to complete.      A crown can be made of acrylic, metal, porcelain, or porcelain bonded to metal. All-porcelain crowns look more like your natural teeth, and therefore are usually used for front teeth, while porcelain bonded to metal is str
