Esthetic Outcomes of Single-Tooth Implant-Supported Restorations Using Metal-Ceramic Restorations with Zirconia or Titanium Abutments: A Randomized Controlled Clinical Study

Long‐Term Survival and Peri‐Implant Health of Titanium Implants with Zirconia Abutments: A Systematic Review and Meta‐Analysis

“…After screening title and abstract, 28 studies potentially fulfilled the eligibility criteria. Finally, eight studies in 10 publications were included in part 1, and 10 studies in 12 publications were included in part 2 . A flow diagram of this study is presented in Figure .…”

Biological effect of the abutment material on the stability of peri‐implant marginal bone levels: A systematic review and meta‐analysis

“…Two other studies assessed the thickness above the bone crest before to implant placement using a calliper (Ferrari et al, The height of the interproximal papilla was assessed by means of the Jemt index (Jemt, 1997) in nine investigations (Baldini et al 2016;Brown & Payne, 2011;Cardaropoli et al, 2006;Carrillo de Albornoz et al, 2014;Fenner et al, 2016;Henriksson & Jemt, 2003;Santing et al, 2013;Thoma et al, 2016;Zembic et al, 2013), or by measuring this papilla height in study casts in one study (Gallucci et al, 2011). The comparisons among the different abutment materials have rendered heterogeneous results, with one study reporting higher papilla index for titanium when comparing to zirconia abutments (Baldini et al 2016), vs. another study reporting exactly the opposite (Carrillo de Albornoz et al, 2014), or other one reporting no differences irrespective of the abutment material (Zembic et al, 2013). The comparisons among the different abutment materials have rendered heterogeneous results, with one study reporting higher papilla index for titanium when comparing to zirconia abutments (Baldini et al 2016), vs. another study reporting exactly the opposite (Carrillo de Albornoz et al, 2014), or other one reporting no differences irrespective of the abutment material (Zembic et al, 2013).…”

“…The Implant Crown Aesthetic Index (ICAI; Meijer, Stellingsma, Meijndert, & Raghoebar, 2005), which assesses both the aesthetics of soft and hard tissues in comparison with the adjacent teeth, was used in two studies comparing different abutment materials (Baldini et al 2016;Carrillo de Albornoz et al, 2014) and in one CS (Santing et al, 2013). No significant differences were detected between groups, although the first study reported a clear tendency for better outcomes when zirconia was compared with titanium abutments, both for colour and for surface of the mucosa.…”

“…The patient's aesthetic perception was evaluated by means of a visual analogue scale (VAS) in six studies (Baldini et al 2016;Carrillo de Albornoz et al, 2014;Fenner et al, 2016;Hosseini et al, 2011;Nilsson et al, 2017;Schepke et al, 2017) and by means of a questionnaire in four (Hosseini et al, 2013;Santing et al, 2013;Vanlioglu et al, 2012;Wannfors & Smedberg, 1999). The patient's aesthetic perception was evaluated by means of a visual analogue scale (VAS) in six studies (Baldini et al 2016;Carrillo de Albornoz et al, 2014;Fenner et al, 2016;Hosseini et al, 2011;Nilsson et al, 2017;Schepke et al, 2017) and by means of a questionnaire in four (Hosseini et al, 2013;Santing et al, 2013;Vanlioglu et al, 2012;Wannfors & Smedberg, 1999).…”

Titanium-Reinforced Zirconia Abutments Versus Pure Zirconia Abutments for Implant-Supported Single Tooth Restorations: A Systematic Review.

“…However, this lack of RCTs could be attributed to the narrow scope of the review, since RCTs were found comparing other types of implant abutments. Baldini et al (23) ; Cosgarea et al (24) ; Carrillo de Albornoz et al (25) ; Ferrari et al (26), (27) ; Sailer et al (28) ; Zembic et al (29), (30) , compared different types of titanium abutments versus zirconia; while others compared between the different types of zirconia abutments: Büchi et al (31) and Thoma et al (32) compared the veneered zirconia versus white zirconia; Paolantoni et al (33) compared one-piece versus two-piece custom made zirconia anchorages and final prosthetic restoration; and Schepke et al (34) reported the comparison between stock versus customized zirconia.…”
