SBA is a reliable and predictable technique to gain horizontal ridge width with simultaneous implant placement. Crest ridge angulation can be used as a tool to predict bone gain at 9 mm apical to the bone crest.
Higher implant stability was found in mandible compared with maxilla in both periods, immediately after insertion and 4 months later. Therefore, according to ISQ values, restoring implants immediately after insertion or after a healing period of 4 months represents safe time points.
This article proposes an evidence based decision tree that serves to guide clinicians on the feasibility of endodontic treatment of a non-vital tooth. It is a reference that clinicians can use when deciding to save or extract a non-vital tooth. Several factors that are commonly encountered in daily practice are considered in this proposed decision-making process and they are history of endodontic treatment, status of previous endodontic treatment, presence/absence of active infection, size of apical radiolucency, periodontal status and patient´s preference.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
