Trends in implant dentistry: Implant systems, complications and barriers in Riyadh, Saudi Arabia.

Background: Patients who are partially dentate or edentulous can receive both conventional and implantsupported fixed prostheses, which leads to improvement in function, esthetics and self-esteem. Currently, implant dentistry is one of the fastest-growing disciplines in dentistry.

Objectives: The aim of the study was to assess the education and training of dentists practicing implant therapy in the Riyadh region of Saudi Arabia, including their preferred dental implant systems, the clinical complications experienced as well as the barriers to implant therapy they encounter.

Timeframe of socket cortication after tooth extraction: A retrospective radiographic study.

Objectives: To assess the timeframe between tooth extraction and radiographically detectable socket cortication in humans.

Methods: Two hundred and fifty patients with a CT scan ≤36 months after tooth extraction were included. First, three orthoradial multiplanar reconstruction slices, representing the major part of the extraction socket, were scored regarding the degree of bone healing as (i) healed, that is, complete/continuous cortication of the socket entrance, or (ii) non-healed.
