Medium-term outcome of Astra Tech implants in head and neck oncology patients

Dental implants in patients with head and neck cancer—A systematic review and meta‐analysis of the influence of radiotherapy on implant survival

“…Furthermore, Ettl et al (2020) concluded that radiation with a dose of over 60 Gray negatively influenced implant success ( p = .025). Contrary to that, other studies found only a minor influence of radiotherapy on the outcome of dental implantation (Alberga et al, 2020; Dholam et al, 2013; Laverty et al, 2019; Moore et al, 2019; Patel et al, 2020; Woods et al, 2019) or even resulted in comparable survival rates for implants placed in the two above‐mentioned groups (Ch'ng et al, 2016; Gander et al, 2014; Pieralli et al, 2021). All irradiated patients included into the studies by Doll et al (2015) and Hessling et al (2015) were treated with radiochemotherapy.…”

“…However, 18 studies investigated in the current literature research were not used for meta‐analysis. Besides the reasoning of too short of a follow‐up (Alberga et al, 2020; Burgess et al, 2017; Ch'ng et al, 2016; Gander et al, 2014; Hessling et al, 2015; Moore et al, 2019; Pompa et al, 2015; Woods et al, 2019), the second reason for exclusion was that the studies only assessed implants placed in irradiated bone, which means they were lacking a non‐irradiated control group (Buurman et al, 2013; Curi et al, 2018; Di Carlo et al, 2019; Nack et al, 2015; Neckel et al, 2020; Papi et al, 2019; Rana et al, 2016; Sandoval et al, 2020). Ettl et al (2020) were reporting implant success using a modified version of the Albrektsson criteria (Albrektsson et al, 1986), and their study was therefore excluded.…”

“…Neckel et al (2020) and Papi et al (2019) for example could not find a significant difference in crestal bone loss comparing the mode of radiotherapy. Although Gander et al (2014) reported six implant failures in only two patients treated with conventional radiotherapy compared with six implant failures in 19 patients treated with IMRT, there was no significant difference found between IMRT and conventional radiotherapy due to the small number of patients receiving conventional radiotherapy. In this review, many studies reported the use of dose distributing techniques such as IMRT and volume‐modulated arch therapy (VMAT (Teoh et al, 2011)) as radiation modality for at least some or even all patients (Alberga et al, 2020; Ch'ng et al, 2016; Curi et al, 2018; Ernst et al, 2016; Gander et al, 2014; Neckel et al, 2020; Papi et al, 2019; Pieralli et al, 2021; Sandoval et al, 2020).…”

Effect of advanced age and/or systemic medical conditions on dental implant survival: A systematic review and meta‐analysis

“…Seventeen studies were identified which met the inclusion and exclusion criteria (Table ) (Arcuri, Fridrich, Funk, Tabor & LaVelle, ; Bodard et al., ; Buddula et al., ; Cuesta‐Gil et al., ; Eckert, Desjardins, Keller & Tolman, ; Ernst et al., ; Fenlon et al., ; Gander, Studer, Studer, Gratz & Bredell, ; Heberer, Kilic, Hossamo, Raguse & Nelson, ; Hessling et al., ; Korfage et al., ; Linsen, Martini & Stark, ; Mancha de la Plata et al., ; Mericske‐Stern, Perren & Raveh, ; Pompa et al., ; Sammartino, Marenzi, Cioffi, Tete & Mortellaro, ). Most of the studies reported on implants placed after radiotherapy (Arcuri et al., ; Bodard et al., ; Ernst et al., ; Gander et al., ; Heberer et al., ; Hessling et al., ; Korfage et al., ; Linsen et al., ; Mancha de la Plata et al., ; Pompa et al., ; Sammartino et al., ). Only two studies also included patients with implants placed prior to radiotherapy (Hessling et al., ; Mericske‐Stern et al., ).…”

Smoking and dental implants: A systematic review and meta-analysis

“…99,103,104,111,112,117 clearly defined what kind of smoking patients were included in their studies based on how many cigarettes the patients used to smoke per day.Fig. 1 -Study screening process.…”
