Alveolar ridge preservation in defect sockets in the maxillary aesthetic zone followed by single-tooth bone level tapered implants with immediate provisionalization: a 1-year prospective case series

open access: yesInternational Journal of Implant Dentistry, 2021
Background Clinical studies of single-tooth replacement in compromised bone using bone level tapered implants in the aesthetic zone are scarce. Aim To assess clinically, radiographically and aesthetically over 1 year the performance of a bone level ...

Determinants of alveolar ridge preservation differ by anatomic location [PDF]

open access: yesJournal of Clinical Periodontology, 2013
AbstractAimTo investigate and compare outcomes following alveolar ridge preservation (ARP) in posterior maxilla and mandible.MethodsTwenty‐four patients (54 ± 3 years) with single posterior tooth extraction were included. ARP was performed with freeze‐dried bone allograft and collagen membrane.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Alveolar ridge preservation with autologous particulated dentin—a case series [PDF]

open access: yesInternational Journal of Implant Dentistry, 2017
Ridge preservation can be performed with autologous bone, alloplastic bone substitute material or a combination of both. Dentin is similar to bone in its chemical composition. In its use as bone substitute material, it undergoes a remodelling process and transforms to bone. The presented case report introduces a technique in which the extraction socket

ALVEOLAR RIDGE PRESERVATION TECHIQUES

open access: yes, 2021
Tehnike očuvanja alveolarnog grebena složeni su kirurški protokoli kojima se nastoji smanjiti resorpcija alveolarnog grebena. Dimenzijske promjene alveolarnog grebena koje nastaju kao posljedica ekstrakcije zuba veće su u odnosu na promjene grebena ...

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.
