Immediate implant in the posterior region combined with alveolar ridge preservation and sealing socket abutment: A retrospective 3D radiographic analysis

Abstract

Background Customized sealing socket abutment (SSA) has been claimed to optimize the peri‐implant hard and soft tissues in type 1 implant placement. However, the evidence to claim the benefits of this technique over the use a conventional healing abutment remains weak. Purpose The aim of this retrospective study was to provide a 3D‐radiographic evaluation of hard tissues changes following immediate implant placement in molar sites combined to ARP technique and installation of SSA. Materials and Methods Baseline and follow‐up (FU) CBCTs (from 1 to 5 years) of 26 patients were collected and included in the study. Baseline and FU CBCTs were superimposed and horizontal and vertical bone changes were assessed. Results A total of 26 patients and 27 implants were included. Horizontal bone remodeling was not significant in any of the measured areas except in the most cervical level, where a mean bone remodeling of 0.73 mm was found. Proximal and buccal vertical bone changes were not significant. Conclusions Within the limits of a retrospective study, dimensional alveolar ridge changes 1 to 5 years after immediate implant placement in molar sites with simultaneous ARP technique and installation of SSA seem to be very limited.

Immediate implant placement in the mandibular posterior region combined with ridge preservation and socket sealing with custom healing abutments and delayed loading protocol. A radiographic evaluation of vertical and horizontal alveolar bone changes

“…This value was located within the normal range of bone resorption that is reported in the literature [29][30][31][32] . Similarly, in a retrospective study 3 , the authors reported stable vertical bone loss at all investigated implant surfaces following immediate implant placement in extraction sockets and replacement of socket sealing abutments. Also, Cheng et al 33 demonstrated a stable vertical bone dimension for immediate implant in posterior region when combined with bone grafting (deproteinized bovine bone mineral).…”

“…The use of CBCT in monitoring alveolar bone changes around the implants was advocated in several studies 7,22,27,28 . One year follow-up was used as it has been reported that most of bone remodeling occurred around immediately placed implants happened with the first year after implant insertion and no extensive bone loss occurred thereafter 3 . At all implant surfaces, vertical bone loss (P-BIC) did not exceed 1.2mm in the first year.…”

“…There is a consensus in the literature that immediate implant placement in extraction sockets in molar region provide several advantages such as reduced treatment time, decreased surgical trauma and preservation of remaining bone 2 . Such treatment proved a high (96.6%7) implant survival rate 3 . It has been reported that ridge preservation with the use of bone grafting biomaterials can minimize bone resorption after extraction and can preserve the contour of the alveolar ridge 4 .…”

“…Reviewing the literature, there is a limited number of studies concerned with the evaluation of vertical and horizontal alveolar bone changes after placement of custom healing abutments for immediate implant placement in extraction socket 3,9 . Moreover, the radiographic evaluation of the automatic profile generator custom healing abutments on alveolar bone height changes was not a concern.…”

Relevant factors of posterior mandible lingual plate perforation during immediate implant placement: a virtual implant placement study using CBCT

“…IIP in the posterior mandible can provide faster recovery of masticatory function in selected scenarios [ 3 , 25 , 26 ]. However, surgeons need to try their best to prevent serious complications such as LPP.…”
