Abstract
The management of the alveolar socket is fundamental to create conditions that would allow the positioning of dental implants in the same site, when required. A number of biomaterials were described in scientific literature to be used for alveolar socket preservation immediately after tooth extraction: autogenous grafts, allograft (of various origin), and synthetic products. Among the autogenous biomaterials, some authors proposed the use of autogenous dentin and/or enamel, retrieved from teeth, adequately managed, and purified. The present case report with two-year follow-up shows one case of alveolar socket preservation by using tooth graft material that was subsequently treated with one implant-supported rehabilitation in the same site. The paper presents clinical and histological outcomes and confirms the feasibility of adopting such autogenous biomaterial in standard procedures.
Highlights
The possibility of positioning dental implants in sites that underwent tooth extraction is strictly related on the amount of the available bone volume that results from bone healing and remodeling after tooth removal
In order to overcome the presence of insufficient available bone volume, a number of surgical procedures were described and validated by scientific literature aimed at increasing the bone volume [2]
6.78 mm demineralized dentin matrix (DDM) and demineralized bone matrix (DBM) are predominantly composed of type I collagen (95%) and noncollagenous proteins (NCPs), and, among them, growth factors; for such reason, human DDM is a biological collagenous scaffold containing osteoinductive growth factors that provides an appropriate environment for stimulating new bone formation [10]
Summary
The possibility of positioning dental implants in sites that underwent tooth extraction is strictly related on the amount of the available bone volume that results from bone healing and remodeling after tooth removal. MacBeth and colleagues in 2017 published one systematic review of the literature and reported that alveolar ridge preservation (ARP) may limit the necessity of further guided bone regeneration (GBR) procedures, reducing the bone changes during the healing period [4]. Such results confirmed what was found in previously published systematic reviews of the literature [5, 6]. In 2018, Bono et al [12] described that deciduous teeth could be used as grafting materials in bone augmentation procedures They shed light on the effects of demineralization on deciduous teeth material, evaluating whether or not collagen and BMP-2 protein contents were preserved after the chemical treatment. The aim of the present report is to present a case of ARP using autogenous deciduous tooth material, presenting both clinical and histologic results
