Safety and Efficacy of a New Synthetic Material Based on Monetite, Silica Gel, PS-Wallastonite, and a Hydroxyapatite Calcium Deficient: A Randomized Comparative Clinic Trial.

: Maxillary bone defects related to post-extraction alveolar ridge resorption are usual. These defects may lead to failure in further surgical implant phases given the lack of bone volume to perform the dental implant. The objective of this clinical assay was to evaluate the safety and efficacy of an experimental synthetic bone substitute in the preservation of post-extraction maxillary alveoli.

Meta-analysis of the etiology of odontogenic maxillary sinusitis.

Objective: To identify and evaluate the frequency of the different odontogenic conditions that may lead to maxillary sinusitis.

Study Design: An observational and retrospective meta-analysis was carried out on 770 cases of maxillary sinusitis obtained from a literature review of 15 articles.

Results: Maxillary sinusitis most commonly manifests itself as chronic maxillary sinusitis.
