Nonendodontic coronal resection of fused and geminated vital teeth. A new technique.

A new technique has been devised to resect vital malformed large dental crowns stemming from developmental fusion and gemination. In two cases from separate patients, resection of the fused crown with sharp osteotomes resulted in exposed pulp chambers that were subsequently allowed to heal. Root canal treatment was not necessary. Case follow-up at 12 and 4 years after orthodontics showed pulp vitality. A review of the literature as well as an explanation for healing modality were included.
