“…13,14,21 It is also possible to achieve good results following the removal of these teeth using fixed appliances, although treatment times tend to be increased and appropriate mechanics need to be used. 33,34 It is not advisable to extract a healthy premolar for orthodontic purposes if the first permanent molar in the same quadrant is heavily restored.…”

This article summarises recently updated guidelines produced by the Clinical Governance Directorate of the British Orthodontic Society through the Clinical Standards Committee of the Faculty of Dental Surgery, Royal College of Surgeons of England (FDSRCS) on the extraction of first permanent molars in children. The first permanent molar is susceptible to chronological enamel defects, molar-incisor hypomineralisation and caries, which may necessitate enforced extraction in the developing dentition. In the right circumstances, the extraction of these teeth can be followed by successful eruption of the second permanent molar and ultimately, third molar eruption to complete the molar dentition. For this reason, elective extraction of first permanent molars with a questionable long-term prognosis should be considered when planning enforced extractions. However, a number of factors can influence the decision-making process, including the necessity for a general anaesthetic to allow extraction, potential cooperation with restorative or orthodontic treatment and likely future preventative practice within the family. Moreover, the presence of any underlying malocclusion also needs to be evaluated within the context of extraction planning. The current available evidence has been evaluated and awarded a grade based upon those recommended by the Scottish Intercollegiate Guidelines Network.

“…Space closure should be planned such that the midlines remain coincident and the arches should not get skewed maintaining a Class I buccal segment relation bilaterally. [7] The space closure objectives should establish the posterior occlusion before finishing the anterior segment as predetermined on a Kesling setup. [8] The final occlusion should be aimed such that it provides a mutually protected occlusion.…”

Orthodontic treatments involving missing or compromised first permanent molars are often challenging cases to treat considering the loss of potential anchor tooth. The case series presents orthodontic treatment in three patients with mutilated/ absent first permanent molars. The treatment goals were to be accomplished by extraction of compromised teeth and retention of healthy dentition. The diagnosis and problem list needed extractions to accomplish the treatment goals. The possibility of extracting compromised first permanent molars instead of other healthy teeth was considered. A setup was done to determine the final occlusion in asymmetric extraction cases. Fixed appliances were used with simple mechanics without any additional anchorage devices. Case-based retention protocols were followed. All the three patients achieved the predetermined treatment objectives of improved esthetics and healthy and stable functional occlusion. The simple and efficient mechanics and finishing techniques for comprehensive orthodontic treatment with first molar extractions presented in the report should help clinicians when treating similar patients.

“…The orthodontic-only (without SA) mesialization of posterior teeth is difficult, if not impossible to achieve without secondary effects on the teeth positioned anteriorly to the space. 1 The use of SA allows for stabilization of anterior teeth while posterior teeth are being pulled mesially, as an indirect source of anchorage, or allow for direct traction of the posterior segments. [2][3][4] It is important to note that even with SA, mesial movement of posterior segments is slow and difficult.…”
