A 5-year longitudinal study of survival rate and periodontal parameter changes at sites of dilacerated maxillary central incisors

Abstract

BackgroundAlthough dental dilaceration disinclusion is an accepted treatment modality, few studies have evaluated the prognosis for dilacerated maxillary incisors and changes in clinical periodontal parameters still need to be demonstrated. The objectives of this study were to evaluate the prognosis and changes in clinical attachment level (CAL), probing depth (PD), and soft tissue recession (REC) for disincluded dilacerated maxillary incisors.MethodsTen impacted dilacerated teeth were scheduled for disinclusion. Five of them were disincluded with the apically repositioned flap technique and the other five with the closed eruption technique and brought into alignment with light orthodontic forces.ResultsAll the dilacerated teeth were disincluded as planned. CAL, PD, and REC were the same as natural teeth. Among the two surgical techniques, no statistically significant differences have been found.ConclusionThe choice to disinclude dilacerated central maxillary incisors reached the goals planned. Periodontal parameters obtained in a short- and long-term follow-up allow to affirm that the disinclusion of dilacerated teeth has a good survival rate.

Orthodontic and surgical treatment of a patient with an impacted upper central incisor with dilacerations – systematic review of the literature with presentation of a case

“…After the procedure, the contour of the gingival margin of the extruded incisor was consistent with the unilateral incisor, the position of the gum margin in 68% of extruded incisors was the same as in the case of the unilateral incisors of the opposing side, while the remaining 32% were more apical. In the 5-year follow-up of the group of 10 patients with an impacted upper central incisor, half of whom underwent the surgical closed technique procedure of tooth uncovering and the other half underwent the closed method, Farronato [36] observed no statistically significant difference in periodontal tissue measurements (probing depth, clinical level of the attachment and gingival recessions) to the teeth naturally erupted. Periodontal procedures on the periodontium of the extruded tooth may contribute to increasing the width of keratinized gingiva and improving the aesthetics [25].…”

Sagittal and vertical effects of transverse sagittal maxillary expander (TSME) in three different malocclusion groups

“…Sagittal arch development is indicated when the arch form is constricted since it helps resolve anterior crowding and proclination of the incisors. Labial movement of the anterior teeth may be combined with transverse development of the buccal segments where indicated [ 26 , 27 ].…”

Orthodontic-surgical management of an unusual dilacerated maxillary incisor

“…However in recent reports, orthodontic-surgical treatment of impacted maxillary incisors is generally successful but with a relatively long treatment duration as treatment usually commences in the early mixed dentition. [ 3 4 5 ] However, there remains the risk of failure due to an intractable position, ankylosis, external root resorption and root exposure after orthodontic traction. [ 3 6 ] The presence of significant tooth dilaceration is a clinical challenge and often requires the need for multiple surgeries to enhance effective traction and to improve gingival aesthetics.…”
