Retrospective Evaluation of the Influence of the Collar Surface Topography on Peri-implant Bone Preservation

Dental Implants with Different Neck Design: A Prospective Clinical Comparative Study with 2-Year Follow-Up

“…According to Eshkol-Yogev et al [44], round neck implants may significantly increase primary stability when compared to triangular neck design. In a paper by Mendoca et al [45], bone remodeling showed to be of benefit around implants with rough collar design, in mandible but not in maxilla, if compared to machined collar surface implants. In a review by Koodaryan et al [46], rough-surfaced micro-threaded neck implants appeared to lose less bone compared to polished and rough-surfaced neck implants.…”

Influence of rough micro-threaded and laser micro-textured implant-neck on peri-implant tissues: A systematic review

“…This process eliminated uncontrolled studies, those that did not compare implant neck designs, and those with inadequate data (n = 82). Thus, six RCTs, five prospective studies, and four retrospective studies (n = 15) that fulfilled the eligibility criteria were chosen ( Aslroosta et al, 2021 , Chappuis et al, 2016 , den Hartog et al, 2013 , den Hartog et al, 2017 , Farronato et al, 2014 , Guarnieri et al, 2014 , Guarnieri et al, 2018 , Khorsand et al, 2016 , Ribes-Lainez et al, 2017 , Mendonca et al, 2017 , Nickenig et al, 2013 , Patil et al, 2020 , Peñarrocha-Diago et al, 2013 , Rothamel et al, 2022 , Sánchez-Siles et al, 2015 ). Table 1 provides detailed data on soft tissue assessments from included studies.…”

“…Two studies used computed tomography to measure MBL ( Chappuis et al, 2016 , Farronato et al, 2014 ), while three used panoramic radiography ( Farronato et al, 2014 , Nickenig et al, 2013 , Rothamel et al, 2022 ). Standardized periapical radiographs were used in 10 studies to evaluate changes in MBL ( Aslroosta et al, 2021 , den Hartog et al, 2013 , den Hartog et al, 2017 , Farronato et al, 2014 , Guarnieri et al, 2014 , Guarnieri et al, 2018 , Khorsand et al, 2016 , Mendonca et al, 2017 , Patil et al, 2020 , Peñarrocha-Diago et al, 2013 ). Two independent reviewers performed quality assessment of RCTs using the Cochrane Collaboration tool to determine RoB.…”

“…Among the selected studies, six were RCTs ( den Hartog et al, 2013 , Farronato et al, 2014 , den Hartog et al, 2017 , Khorsand et al, 2016 , Peñarrocha-Diago et al, 2013 , Rothamel et al, 2022 ). Five were prospective studies ( Aslroosta et al, 2021 , Chappuis et al, 2016 , Guarnieri et al, 2018 , Nickenig et al, 2013 , Patil et al, 2020 ), while four were retrospective studies ( Guarnieri et al, 2014 , Ribes-Lainez et al, 2017 , Mendonca et al, 2017 , Sánchez-Siles et al, 2015 ). Additionally, three studies incorporating implants with LMS necks were included to assess clinical effectiveness of the design ( Farronato et al, 2014 , Guarnieri et al, 2014 , Guarnieri et al, 2018 ).…”

A review on the prevention of inflammatory periimplant diseases

“…Moderately rough titanium surfaces play an osteoconductive role and undergo optimal osseointegration without enhancing bacterial biofilm accumulation. [43] Rough titanium collars minimize marginal bone remodeling [44] and promote bone and soft connective tissue formation. [45] Marginal bacterial biofilm accumulation is undoubtedly the necessary condition for IPD initiation and the possibility for bacteria to access intra-implant reservoirs is probably the way they use to have an easier access to marginal bone.…”
