Clinical evaluation of submerged and non-submerged implants for posterior single-tooth replacements: a randomized split-mouth clinical trial

Early and late implant failure of submerged versus non‐submerged implant healing: A systematic review, meta‐analysis and trial sequential analysis

“…Ten of the 11 included studies were prospective RCTs (Becktor et al., ; Cecchinato et al., ; Cordaro et al., ; Eliasson et al., ; Engquist et al., ; Enkling et al., ; Gulati et al., ; Heijdenrijk et al., ; Nemli et al., ; Tallarico et al., ), while 1 was a prospective non‐RCT (Torkzaban et al., ). Six Studies had a parallel design (Becktor et al., ; Cordaro et al., ; Engquist et al., ; Heijdenrijk et al., ; Tallarico et al., ; Torkzaban et al., ), two had a mixed design (Cecchinato et al., ; Gulati et al., ) and the remaining three had a split‐mouth design (Eliasson et al., ; Enkling et al., ; Nemli et al., ). The follow‐up time, after implant placement ranged between 6 months and 5 years.…”

“…After the first screening, 26 articles were considered eligible and read in full text. At the end of the full-text evaluation, only 11 articles fulfilling inclusion criteria were selected for data extraction (Becktor, Isaksson, & Billstrom, 2007;Cecchinato et al, 2008;Cordaro, Torsello, & Roccuzzo, 2009;Eliasson et al, 2010;Engquist et al, 2005;Enkling et al, 2011;Gulati et al, 2015;Heijdenrijk, Raghoebar, Meijer, Stegenga, & van der Reijden, 2006;Nemli et al, 2014;Tallarico, Vaccarella, & Marzi, 2011;Torkzaban, Arabi, Roshanaei, Rostami, & Soheilifar, 2015). Fifteen papers were excluded (Abrahamsson, Berglundh, Moon, & Lindhe, 1999;Astrand et al, 2002;Boioli, Penaud, & Miller, 2001;Cochran et al, 2011;Cordaro et al, 2013;Degidi, Piattelli, Gehrke, & Carinci, 2006;Friberg & Jemt, 2015;Garcia, Kraehenmann, Bezerra, Mendes, & Rapp, 2008;Lambrecht, Filippi, Kunzel, & Schiel, 2003;Lang et al, 2007;Marcelis, Vercruyssen, Nicu, Naert, & Quirynen, 2012;Moberg et al, 2001;Naert, Gizani, & van Steenberghe, 1999;Sanchez-Siles, Munoz-Camara, Salazar-Sanchez, Camacho-Alonso, & Calvo-Guirado, 2016;Sanz, Ivanoff et al, 2015).…”

“…The follow-up time, after implant placement ranged between 6 months and 5 years. Six studies were at low risk of bias (Becktor et al, 2007;Cecchinato et al, 2008;Cordaro et al, 2009;Eliasson et al, 2010;Enkling et al, 2011;Tallarico et al, 2011), while five were at high risk of bias (Engquist et al, 2005;Gulati et al, 2015;Heijdenrijk et al, 2006;Nemli et al, 2014;Torkzaban et al, 2015). A summary of the risk of bias in the included studies is reported in Figure 2.…”

Comparison of Clinical, Radiographic, and Immunologic Inflammatory Parameters around Crestally and Subcrestally Placed Dental Implants: 5‐Year Retrospective Results

“…The effect of single stage implant placement versus submerged healing has been previously investigated, showing comparable clinical and radiographic results . However, peri‐implant CBL has been demonstrated by others to be significantly higher in the submerged healing group . Furthermore, nonsubmerged implants resulted in higher patient satisfaction due to decreased surgical intervention .…”

“…[36][37][38][39][40][41][42][43][44] However, peri-implant CBL has been demonstrated by others to be significantly higher in the submerged healing group. [45][46][47][48] Furthermore, nonsubmerged implants resulted in higher patient satisfaction due to decreased surgical intervention. 45,48 In a Cochrane systematic review of five randomized controlled clinical trials, 49 the one-stage approach was preferable in partially edentulous patients since it avoids one surgical intervention and shortens treatment times, while a two-stage submerged approach could be indicated when an implant has not obtained an optimal primary stability, when barriers are used for guided tissue regeneration, or when it is expected that removable interim prostheses could transmit excessive forces on the penetrating abutments.…”
