Serial extraction: 20 years of follow-up

Abstract

This paper reports a case treated by a serial extraction program at the mixed dentition stage followed by a corrective orthodontic treatment, with a long-term follow-up period. Twenty years after the interceptive treatment, a harmonious face was observed along with treatment stability in the anterior posterior direction, deep overbite (which has been mentioned as a disadvantage of the serial extraction program), and a small relapse of anterior tooth crowding. All these conditions have been regarded as normal occurrences for most orthodontic treatments with a long-term follow-up period. This case report demonstrated that the establishment of a serial extraction protocol determined relevant esthetic changes that afforded an improvement of the patient's self-esteem, with a positive social impact. Furthermore, the low cost of this protocol permits the use of this therapy with underprivileged populations. It is important to emphasize that an early correction of tooth crowding by this protocol does not guarantee stability, but small relapses do not invalidate its accomplishment.

Interceptive Orthodontics — Current Evidence

“…In reality, they adopt the idea that the problem is maintained and the crowding shifts to involve the permanent cuspids. They remind us with the most basic canon of the health profession which is "first do no harm" [52].…”

“…Serial extraction can be defined as the correctly timed, planned removal of certain deciduous and permanent teeth in mixed dentition cases with dento-alveolar disproportion in order to: Alleviate crowding of incisor teeth and to allow unerupted teeth to guide themselves into improved positions (canines in particular), and to lessen (or eliminate) the period of active appliance therapy. Thus, it is one of the positive interceptive orthodontic procedure generally applied in most discrepancy cases where supporting bone is less than the total tooth material [48].…”

Ekstraksjon av primære tenner med kjeveortopedi som oppgitt årsak hos barn og ungdom i Vestfold og Telemark fylkeskommune

“…Panoramarøntgen kan gi en beskjeden forekomst av overdiagnostisering sammenlignet med Cone Beam Computer Tomografi (CBCT), men regnes som godt nok til å stille diagnosen sammenlignet med undersøkelse med CBCT (5). Antall pasienter som fikk sine primaere hjørnetenner fjernet var klart høyere enn den anslåtte forekomsten av retinerte, permanente hjørnetenner i befolkningen.Såkalt «serie-ekstraksjon» hvor primaere hjørnetenner og første primaere molar ekstraheres, etterfulgt av første permanente premolar, har sine tilhengere innen kjeveortopedien(8,9). At dette gir et bedre resultat enn om man lar tennene felles naturlig og deretter igangsetter kjeveortopedisk behandling, synes å vaere usikkert(6,10).…”
