Volume Measurements

This case report describes a digital workflow used for three main purposes: to predict the volume of particulate grafting material required to perform alveolar ridge preservation; to conduct subsequent virtual implant planning; and to digitally design the respective implant-supported crown. The volume of equine-derived bone grafting material required for filling the alveolar socket is digitally estimated in cubic millimeters from cone beam computed tomographic (CBCT) data using a specific software tool for volume measurements. Digital crown design from an intraoral scan allows for milling the definitive implant-supported crown. For this purpose, a scan body can be used and even slightly trimmed externally to avoid excessive proximity with an adjacent rotated tooth.

Bone Height

After tooth extraction, notable ridge alterations occur due to resorption of bundle bones during the healing process. In areas with thin or damaged socket walls and multiple adjacent tooth extraction, dimensional changes are more prominent in the marginal proportion. In addition to the marginal changes, upper molar teeth are also vulnerable to pneumatization of the maxillary sinus. To reduce dimensional changes in extraction sockets, alveolar ridge preservation (ARP) is favored by many clinicians in areas where a large amount of dimensional change is expected. This case report presents two cases of ARP using collagenated demineralized bovine bone mineral and demineralized porcine bone mineral in the apically involved upper premolar and molar, respectively. Implants were placed one and two years, respectively, after the ARP. Radiographic analyses of residual bone height and volume were measured using cone-beam-computed tomography (CBCT) and histologic analysis of newly formed mineralized bone and residual graft material percentages were measured from the collected tissue samples using a trephine bur. Implants were placed using a simple technique, without any additional bone grafts at the marginal proportion. The ARP technique could maintain the alveolar bone height and volume, as well as minimize the invasiveness of surgical procedures during implant surgery.

Immunogenic Properties

Tooth extraction is a surgical procedure that is performed due to pulp and periapical pathology, periodontal disease, or teeth that are not deemed to be prosthetically or endodontically restorable. Following tooth extraction, bone resorption and vertical or horizontal defects occur. Traditionally, ridge preservation warrants the use of different agents such as autografts, allografts, xenografts, and mineral or ceramic materials. Autogenous dentin grafts are alternative to ridge preservation with osteoconductive, osteoinductive, and non-immunogenic properties to generate bone formation. The aim of the case report was to evaluate and compare clinical and histological outcomes using an autogenous dentin graft versus an allogeneic bone graft (DFDBA) as an alternative for ridge preservation.

Teeth Extraction

Alveolar ridge resorption is a natural consequence of teeth extraction, with unpleasant aesthetic and functional consequences that might compromise a future oral rehabilitation. To minimize the biological consequences of alveolar ridge resorption, several surgical procedures have been designed, the so-called alveolar ridge preservation (ARP) techniques. One important characteristic is the concomitant use of biomaterial in ARP. In the past decade, autogenous teeth as a bone graft material in post-extraction sockets have been proposed with very interesting outcomes, yet with different protocols of preparation. Here we summarize the available evidence on autogenous teeth as a biomaterial in ARP, its different protocols and future directions.
