Mandibular Molar Protraction
Many orthodontists worry about the spacing in the mandibular arch whether it is due to second molar extraction or due to the missing second premolar. Missing mandibular molar can cause problem such as posterior spacing. If the clinician wants to go for a prosthetic outlook, then there should be left an exact amount of space in the arch and alveolar ridge should be kept unharmed. There are conditions in which the patient desires for a whole set of natural dentitions as well as cases where molar mesialization can correct the malocclusion and simultaneously improve the profile of the patient. There are various appliances which make this mechanism possible which include loop mechanics such as cherryloop, running loop, T loop, V bends and tip back, sliding bends and bars, etc. Recent advances in TADS increased the scope of molar protraction in cases where the retraction of anteriors is not advocated. Without the retraction of the anteriors and premolars, protraction of mandibular second and third molar becomes even more challenging hence TADS can be beneficial. For achieving molar protraction that to mandibular several approaches are being recognized corticotomy assisted molar protraction, PAOO. With this mesialization of the 2nd molar even the impacted 3rd molar can be given space in the arch without surgical intervention. With this treatment natural dentition is achieved i.e., there will be no need of prosthetic implants and bridges for treating cases of missing posteriors. This review articlefocuses on the indications of the molar protraction and the various modalities with which we can achieve mesialization of the posterior segment.
