Abstract: Objective To investigate the effect of creating food escape grooves adjacent to marginal ridge on the improvement of food impaction around implant-supported prosthesis. Methods 41 patients with implant-supported prosthesis in the maxillary and mandibular molar regions complaining of distinct discomfort during chewing caused by food impaction around implants were selected. Food escape grooves were created adjacent to the marginal ridges of implant crowns. The patients were followed up regularly. Results All patients (100%) reported a significant improvement in symptoms of food impaction. Conclusion Creating food escape grooves adjacent to marginal ridge helps to improve the symptoms of food impaction and achieve a high level of patient satisfaction.

Key words: Implant-supported fixed prosthesis, Food impaction, Food escape groove
