Abstract
Dental implantology has evolved significantly since Brånemark
introduced the concept of osseointegration, becoming one of the most
predictable alternatives for the replacement of missing teeth. The success of
implants depends on multiple factors, among which the preservation and
regeneration of the alveolar ridge are decisive, since tooth loss leads to
dimensional changes in hard and soft tissues that compromise prosthetic
rehabilitation. To counteract these changes, various techniques and
biomaterials are employed, such as autografts, allografts, xenografts, and
alloplastic materials. Xenografts, particularly those of bovine origin, have
proven effective by acting as a calcified matrix and reducing post-extraction
bone resorption. Likewise, the use of acellular dermal matrix has shown
favorable outcomes in soft tissue regeneration, as it promotes
revascularization and structural integration without eliciting an immunogenic
response. We present the case of a 45-year-old male patient who attended
consultation due to gingival recession, bleeding, and mobility in tooth 11,
previously treated with endodontics and prosthetic restoration. Clinical and
radiographic findings confirmed the presence of a vertical root fracture.
Surgical extraction was performed, followed by alveolar preservation using a
bovine xenograft and coverage with an acellular dermal matrix. Subsequently,
after eight months, a Straumann titanium implant with immediate loading was
placed, achieving an adequate emergence profile and esthetic restoration with
lithium disilicate crowns.
