Malpositioned Osseointegrated Implants Relocated with Segmental Osteotomies: A Retrospective Analysis of a Multicenter Case Series with a 1‐ to 15‐Year Follow‐Up

Abstract

The present study suggests that implant relocation with segmental osteotomies could be an effective alternative method to correct the position of unrestorable malpositioned implants in a single-stage surgery.

A retrospective study of an alternative technique for implant repositioning in the maxillary esthetic region

“…The procedure was found to have good compliance, as 66.6% of the subjects would undergo this treatment again, if necessary, and the discomfort was considered not high (only two patients [22.2%] experienced high discomfort). Stacchi et al observed similar results after repositioning single dental implants through segmental osteotomy, but no distraction osteogenesis were performed in their study.…”

“…Subjective evaluation of patient satisfaction was assessed during the T3 period based on the results of the questionnaire of Meijndert et al, which was modified by Tymstra et al The questionnaire consisted of an overall satisfaction score ranging from 0 to 10 and two questions regarding the peri‐implant mucosa with scores ranging from 0 to 4. In addition, two questions about discomfort and compliance were evaluated based on a VAS (Visual Analog Scale) score …”

“…Another similar procedure is the direct relocation of the implant‐bone block to the desired position with immediate stabilization by internal rigid fixation . Several cases using this technique have been reported; but only one retrospective study has analyzed the gingival esthetic outcome, the cases in this study all involved the repositioning of single implants but not in cases with vertical alveolar bone atrophy .…”

Repositioning Implants Through Sandwich Osteotomy with the Interposition of Lyophilized Bovine Bone

“…As well as repositioning implants, sandwich osteotomy can be used to treat moderate vertical defects of the alveolar ridge (between 4 and 8 mm). In the literature, the technique has been labeled versatile, viable and predictable, with few complications and a high percentage of success (Raghoebar et al;Cunha et al, 2011;Nóia et al;Bell, 2013;Felice et al, 2014;Xuan et al, 2014;Triaca et al, 2014;Stacchi et al, 2015).…”
