Orthodontic treatment of Class I malocclusion with severe crowding & rotations - 3

-

  Diagnosis:

    A female patient came with the chief complain of irregularly placed upper and lower teeth. The extraoral examination reveals mesoprosopic faceform, mesoocephalic headform, straight profile, competent lips, average nasolabial angle. The intraoral examination shows Class I molar relation, Class I canine relation with crowding in upper & lower anterior teeth, crossbite irt 15, severe rotation irt 15. Diagnosis is Angle's Class I malocclusion with crossbite irt 15, upper and lower crowding.

Treatment Objectives: 
  • To correct crowding in upper & lower anterior teeth
  • To correct crossbite
  • To achieve ideal overjet and overbite
  • To correct smile

Treatment Plan: 
  • Non-Extraction 
  • Leveling and alignment 
  • Inter-proximal reduction 
  • Finishing and detailing

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 and GIC cement is placed on posterior teeth to open the bite. For the correction of upper right second premolar, couple force is applied. The inter-proximal reduction is performed in lower anterior teeth. 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 crossbite is relieved and leveling & alignment is completed, posterior GIC bite block is removed. Finishing & detailing is done on 0.019 x 0.025 braided SS wire by settling elastics. The overall treatment duration is approximately 1 year. After removal of orthodontic appliance, lingual fixed retainer and removable essix retainer are given.




Treatment Results: 

    The post-treatment photographs showed Class I molar and canine relation, ideal overjet and overbite, average nasolabial angle, competent lips, well coordinated arches. The profile & smile are also improved. The pleasing smile is obtained with proper interdigitation of occlusion.

The Inner Lives of Doctors - Doctors are humans too.

Doctors are also human being. Doctors attribute to their profession behind closed doors. As patients, we are so overwhelmed with our own problems. We fail to notice that our doctor may be battling her own problems with a complicated system. They are stuck in a systemic mess. Patients bargaining and don’t pay up regularly. Medico Legal threats. Costs are rising in every things day by day but when doctors rise treatment costs, they have to give justification so much. Life-and-death ethical dilemmas. Burnout. Loss of value in society. Doctors are nudged and hassled in a system from which there’s no way out. Yet, they are held to one of the highest performing standards of any profession. It’s tough being a doctor today.

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. There are a variety of causes for delayed dental development and in most cases they are not given an importance and concern as long as permanent teeth grow eventually. Every child should be seen...
