Health-related QoL (HRQoL) is a dynamic concept referring to an individual’s subjective assessment and perspective of current general health condition as well as functional, social, and emotional well-being [23, 24]. Most people regard oral health as important for QoL, and this is mediated through the concept of oral health-related QoL (OHRQoL) [25]. In this regard, OHRQoL is an important PROM in dental research, as oral health is an integral part of general health and well-being [26].

Different instruments to assess OHRQoL may be utilized to detect changes in physical, functional, and psychosocial impacts of oral disorders and have been validated for use in clinical studies [27,28,29]. The Oral Health Impact Profile-14 (OHIP-14) questionnaire is a widely used OHRQoL instrument [27]. It includes 14 questions covering seven domains of oral health and attempts to assess their impact on patients’ OHRQoL [30, 31]. OHIP-14 has previously been translated into Norwegian and used in a large study (n = 3538) with a calculated Norwegian national norm value [32]. Although previous studies have reported PROMs in relation to bone grafting [9, 33,34,35,36,37,38,39,40,41,42], to our knowledge, only one previous study has systematically assessed impact of donor site harvesting on OHRQoL, where (a) a post-operative lowering of OHRQoL was observed following bone grafting from both intra-oral and extra-oral sites and (b) iliac crest grafts compared to intraoral donor sites had a negative impact on postoperative QoL [37]. Moreover, to our knowledge, only one study has previously assessed the cost-effectiveness of autologous iliac crest grafting [43].

The aim of this study was to assess PROMs such as satisfaction and OHRQoL after advanced reconstruction of alveolar bone by anterior iliac crest-derived grafting and implant treatment.
