Optimizing clinical success with implants: maintenance and care.

Numerous studies have found hydroxyapatite (HA) to be a favorable material for dental implant coatings. Quality HA-coated implants have been shown to heal faster, attach more completely to the bone, and resist flaking and dissolution. However, as with natural teeth, good oral hygiene and proper professional maintenance are essential. To ensure the success of the implant, clinicians must understand that HA coatings vary according to thickness, porosity, attachment strength, and crystallinity, and must recognize the essential features of a quality coating.
