The management of mesially inclined/impacted mandibular permanent second molars

Abstract

Mesially impacted mandibular second molars are a common occurrence in orthodontic practices, especially those using the lingual arch or lip bumper for alleviating anterior crowding. Horizontally impacted second molars, on the other hand, occur so infrequently that most practitioners have limited experience in treating such a patient. Because of this there is little consensus on the management of these cases. As opposed to vertically impacted molars that may be associated with ankylosis or other factors preventing eruption, the mesially angulated, horizontally impacted mandibular second molar usually has eruption potential, because its impaction is more commonly due to lack of space and/or abnormal eruption path. Hence, orthodontic uprighting shows the most promise and can commonly be done without extracting the third molar or surgically exposing the impacted second molar. Modern clinicians have at their disposal a myriad of biomechanical choices that can be used to successfully reposition these teeth and enable finishing with an optimal occlusion.

Surgical Management of Impacted Lower Second Molars: A Comprehensive Review

“…71,72 Furthermore, orthodontic treatment is more or less unnecessary in this type of modality. 73 Currently, there are no specific guidelines when it comes to the transplantation of teeth. 74,75 Many case reports have shown that it is especially beneficial to second mandibular molar space rehabilitation, due to the general claim that transplantations reduce alveolar resorptions.…”

Verticalização de molar com uso de mini implante cabeça de braquete com rosca invertida: Relato de caso

“…A perda dentária se destaca como um dos principais problemas de saúde bucal encontrados na população brasileira, especialmente entre adultos e idosos provocando um desequilíbrio na oclusão, geralmente relacionado com a extrusão do antagonista, mesialização e/ou distalização dos dentes adjacentes ao espaço, contatos prematuros, dentre outros efeitos negativos (Ahmad et al, 2019;Alexander, et al, 2015;Martins-Júnior, et al, 2017;Silva, et al, 2012). A inclinação mesial favorece a formação de defeitos ósseos e bolsas periodontais nas regiões mesiais dos molares e uma redução do espaço interradicular na região distal (Nunes, 2018;Turley, 2020).…”

Treatment of mandibular second molar impaction in a patient with metal hypersensitivity

“…2,[9][10][11][12][13] Past studies have shown that the incidence of unerupted mandibular second molars is 2.3%, of which 0.2% is judged to be due to tooth impaction. [14][15][16][17][18][19][20] While it is becoming more common to treat impacted mandibular second molars in daily clinical practice, 17,18,20 metal hypersensitive patients with unerupted molars are less frequently encountered.…”
