Treatment of ectopic first permanent molar teeth

Abstract

This paper is relevant to every general dental practitioner who treats patients in mixed dentition.

A simple and effective technique to guide the ectopic eruption of a first permanent molar: a case report

“…Premature loss and prolonged retention of primary teeth are important causes of malocclusion 2 . Ectopic eruption is defined as the eruption of a tooth in an atypical position or orientation 3 . It often occurs in the developing mixed dentition, characterized by molar eruption under the distal undercut of the second molar, and consequently failures to erupt in the normal occlusal plane because of the presence of a barrier [4][5][6] .…”

“…It often occurs in the developing mixed dentition, characterized by molar eruption under the distal undercut of the second molar, and consequently failures to erupt in the normal occlusal plane because of the presence of a barrier [4][5][6] . The etiology of the ectopic eruption of the first permanent molar is not completely understood 3,6 . It may be considered to be multifactorial 3 and primarily dependent on the tooth germ position 5 .…”

“…It may be considered to be multifactorial 3 and primarily dependent on the tooth germ position 5 . Most causes are abnormally large first permanent and second primary molars combined with inadequate arch size, and a mesially inclined eruption, among other factors as described by some authors 2,3,6,7 .…”

“…Ectopic eruption affects both genders equaly 3 . It is more frequent in the maxillary arch 8 and the most affected teeth are maxillary first permanent molars and canines, followed by the mandibular canine, mandibular second premolar, and maxillary lateral incisors 4 .…”

“…Thus, impaction mostly occurs in the maxillary first molar during mixed dentition 2,6 . Generally, first molars are affected in approximately 2-6% of the population 3,6,8 . Diagnosis is performed both radiographically (periapical, bitewing, or orthopantomograph) and clinically [2][3][4] .…”
