ABSTRACT
Prevalence of peri-implant complication is expected to be on the rise with the increased number of implants being placed. Depending on the degree of osseous involvement, the clinician needs to decide if the treatment goal is to arrest the disease progression, regeneration or explantation and replacement. Host's medical status, defect configuration, aesthetic outcome, ability to access for plaque control post-treatment, and the patient's wishes are key factors to consider. The purpose of this review is to provide a contemporary synopsis on the management of peri-implantitis with emphasis on explantation. Guidance on the identification of factors/situations where salvaging an implant may be less favourable is discussed and the various techniques to remove a fractured, or peri-implantitis-affected non-mobile implant are described.

The chiral selectivities were altered and high diastereo- and enantio-selectivities of the products were obtained in water medium without adding acid co-catalysts when a primary-tertiary diamine catalyst was immobilized on mesoporous SBA-15 to form a recyclable catalyst for the direct asymmetric aldol reaction of cyclohexanone with p-nitrobenzaldehyde.
