Summary

There is a scarcity in literature regarding the influence of maxillary third molar on distalization . This study aimed to compare the influence of unerupted maxillary third molars and their extraction on the bilateral distalization of upper first molars using the infra-zygomatic gear distalizer

Detailed description

Maxillary molar distalization is one of the non-extraction modalities for treating class II malocclusion. When distalizing maxillary molars In adults, it is not a problem to extract fully erupted third molars, and it may even be suggested that the extraction site may accommodate distalization. On the contrary, adolescents usually have unerupted third molars with partially formed roots, rendering the surgical extraction more difficult and traumatic. The necessity of surgically extracting upper third molar buds before distalization remains questionable. Therefore, this study was conducted to three-dimensionally assess the impact of maxillary third molar presence on distalizing maxillary molars in adolescent patients having Class II malocclusion.

Conditions

• Class II Malocclusion

Interventions

Type	Name	Description
PROCEDURE	Distalization combined with upper third molars extraction	After surgical extraction of unerupted upper third molars, the maxillary first molars were distalized using a labial bow with two soldered crimpable hooks distal to the upper lateral incisors. The labial bow fitted in the flying tube of the upper first molar bands. It was anchored bilaterally to the infra-zygomatic mini-implant by closed coil spring that applied a force of 300gm on each side
PROCEDURE	Distalization without upper third molars extraction	The maxillary first molars were distalized , without extracting upper third molars, using a labial bow with two soldered crimpable hooks distal to the upper lateral incisors. The labial bow fitted in the flying tube of the upper first molar bands. It was anchored bilaterally to the infra-zygomatic mini-implant by closed coil spring that applied a force of 300gm on each side
