This cross-sectional study conducted at the Prosthodontics Centre, Ibn Sina University Hospital in Rabat, Morocco, investigates the dimensions and shapes characterizing maxillary and mandibular edentulous arches in a patient population seeking consultation. The objective is to provide insights crucial for optimizing outcomes in prosthetic therapy, informing decisions on impression trays, occlusion planes, prosthetic teeth, and implant attributes. Sixty-seven edentulous Moroccan patients (40 men, 27 women), aged 31 to 90, were recruited at the Prosthodontics Centre. Maxillary and mandibular casts were meticulously crafted, and precise measurements of anterior and posterior width and length were acquired for both arches. Arch shapes were categorized into O-shape, V-shape, and U-shape. Data were analyzed using Microsoft® Excel 2013 and SPSS software (IBM SPSS Statistics 23). Analysis revealed maxillary arch lengths ranging from 40 to 58 mm, maxillary arch widths from 38 to 58 mm, mandibular arch lengths from 33 to 56 mm, and mandibular arch widths from 30 to 60 mm. The predominant arch shape was the ovoid, constituting 34% (n=23) of maxillary cases and 54% (n=36) of mandibular cases. This study provides novel insights into the dimensions and shapes of maxillary and mandibular edentulous arches in patients seeking consultation at Ibn Sina University Hospital, Rabat, Morocco. The findings offer valuable guidance for prosthetic therapy decisions, emphasizing the importance of integrating established references and arch classifications for optimal outcomes in the treatment of edentulous patients in Morocco.
