Partial maxillary osteotomy following an unsuccessful forced eruption of an impacted maxillary canine: 10 year follow-up. Review and case report

Abstract

The maxillary canines are amongst the most frequently impacted teeth, second only to the third molars. Several conservative orthodontic and surgical techniques are available to position the teeth properly in the dental arch, even in severe cases. However, when an extraction is necessary, it often leaves a critical alveolar defect of difficult management. The authors present the technique of Partial Maxillary Osteotomy, in which a dento-alveolar segment is moved mesially, hence closing the remaining space, allowing for the formation of healthy periodontium and resulting in an adequate functional and aesthetic outcome. A case report is presented with a 10 year follow-up, proving the technique's stability in the long term.

Clinical Consideration and Management of Impacted Maxillary Canine Teeth

“…When an extraction is performed, it often leaves a critical alveolar defect of difficult management. Puricelli et al [67] recommended maxillary partial osteotomy as an efficient resolution for the correction of bone defects within the dental arches which is performed by mobilizing an alveolar bone segment. They have indicated this technique within the concept of individual and multiple sustenance of integrity in occlusion and of the dental arches, especially in young patients, where the indication for fixed prosthetics or osseointegrated implants might be precocious.…”

Positioning of Impacted Canine Teeth by Auto-transplantation After Unsuccessful Orthodontic Traction: Case Report

“…Each tooth has a specific time range for eruption and it is considered to be impacted if it fails to erupt within this expected time (1). Over-retained deciduous canines, supernumerary tooth or odontomas and abnormal eruption pattern of first premolars are local obstructive factors of impaction for maxillary canines (2)(3)(4).…”
