Orthodontic Extractions

-

Introduction: Extractions are routinely used in orthodontics as a method of gaining space. Generally first or second premolars are extracted for orthodontic treatment but there is exceptional cases also. The extraction technique that facilitates teeth removal should be atraumatically. Buccal cortical plates should be preserved for orthodontic tooth movement. Orthodontic tooth extraction is performed after evaluation of clinical records, radiographs and photographs.

Orthodontic Treatment often involves the extraction of teeth to gain space for the correction of crowding or proclined teeth. While, for the patient and the general practitioners performing the procedure the principal concern is to successfully complete the procedure atraumatically, for the orthodontist there is an additional prospective to preserve the cortical plates from breaking during extraction compare to other tooth extractions which can lead to ridge narrowing. Fractured cortical plates can lead to narrowed out ridges that may interfere with complete closure of extraction space closure. Therefore, any technique that eases tooth removal with minimal trauma to the cortical plates is welcome. Background orthodontic extractions are conventionally done preceding the formal banding and bonding procedure. 

Preserving Bone For Moving Teeth
Bone is a living tissue that continually reshapes itself in response to the stimulus of biting force or stress. Bone that normally supports the teeth slowly resorbs when the teeth are lost. Sometimes, if the bony housing surrounding a tooth is very thin, significant bone loss can occur after extraction. This process happens in just a matter of months, but can continue if steps are not taken to stop it. The surgeon removing a tooth may recommend a bone graft to preserve the socket bone if he is concerned that there will be too much bone loss. The reason for this consideration is that if there is insufficient bone through which to move the teeth, it can result in unsightly gum recession and root exposure following orthodontic treatment. Thus bone preservation following tooth extraction is critical to ensure that there is enough bone mass through which to move neighboring teeth for proper alignment.

    Diagnosis:     A female patient came with the chief complain of irregularly placed upper and lower front 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 severe crowding in upper & lower anterior teeth, highly placed upper canines, overretained teeth in upper right & left 2nd deciduous molar, severe rotations present in upper central incisors. Diagnosis is Angle's Class I malocclusion with highly placed canines & severe crowding. Treatment Objectives:  To correct crowding in upper & lower anterior teeth To level & align highly placed canines To correct rotations of upper central incisors To achieve ideal overjet and overbite To correct smile Treatment Plan:  Extraction irt 55,65  Leveling and alignment  Inter-proximal reduction  Finishing and detailing Treatment Progress:

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. 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 by a

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. They are not making as much money as you think. Unlike most high-end professionals, doctors begin making money after age of 35. Even after investing time, money, knowledge so much, they have waiting period so long to set ourselves. After finishing studies also they have to
