Abstract

This study aimed to characterize extraction sockets based on indirect digital root analysis. The outcomes of interest were estimated socket volume and dimensions of the socket orifice. A total of 420 extracted teeth, constituting 15 complete sets of permanent teeth (except third molars), were selected. Teeth were scanned to obtain STL files of the root complex for digital analysis. After digitally sectioning each root 2.0 mm apical to the cementoenamel junction (CEJ), root volume was measured in mm(3) and converted to cc. Subsequently, a horizontal section plane was drawn at the most zenithal level of the buccal CEJ, and the surface area (in mm(2)) and buccolingual and mesiodistal linear measurements of the socket orifice (in mm) were computed. Maxillary first molars exhibited the largest mean root volume (0.451 +/- 0.096 cc) and mandibular central incisors the smallest (0.106 +/- 0.02 cc). Surface area analysis demonstrated that mandibular first molars presented the largest socket orifice area (78.56 +/- 10.44 mm(2)), with mandibular central incisors presenting the smallest area (17.45 +/- 1.82 mm(2)). Maxillary first molars showed the largest mean socket orifice buccolingual dimension (11.08 +/- 0.60 mm), and mandibular first molars showed the largest mean mesiodistal dimension (9.73 +/- 0.84 mm). Mandibular central incisors exhibited the smallest mean buccolingual (5.87 +/- 0.26 mm) and mesiodistal (3.52 +/- 0.24 mm) linear dimensions. Findings from this study can be used by clinicians to efficiently plan extraction-site management procedures (such as alveolar ridge preservation via socket grafting and sealing) and implant provisionalization therapy, and by the industry to design products that facilitate site-specific execution of these interventions.
