How CAD/CAM affects immediate loading in implant dentistry
A graduate of Paris Descartes University (now the University of Paris), Dr Léon Pariente currently runs a private practice in the French capital that specialises in implantology and periodontics. In an upcoming free webinar, he and Dr Karim Dada will discuss how various digital technologies, such as CBCT imaging and CAD/CAM, have replaced traditional modalities and enhanced the aesthetic aspects of restorations. Pariente spoke with Dental Tribune International about this topic ahead of the presentation on Thursday, 25 June.
Dr Pariente, in your experience, how has digital dentistry, particularly the use of CAD/CAM, changed the approach to immediate loading in implant dentistry?
CAD/CAM and digital dentistry now allow us to easily produce surgical guides with great fit, as well as temporary shells that we can use to produce temporary crowns. Merging the files obtained from the CBCT and intra-oral scanners gives us all the information needed to plan the surgery: precise tooth positions, bone volumes and gingival contours.
What are some of the most important factors for the long-term success of immediately placed implants?
The most important factors for long-term success are precise implant positioning, customised soft-tissue contouring, and pressure from the final abutment and crown.
How does immediate implant placement differ in the aesthetic zone from the posterior region?
The aesthetic zone is more challenging for the following reasons: the papillae are longer, the buccal plate is thinner, and the available bone for primary stability can be more challenging to find.
What do you see as the main benefits of immediate loading?
From the patient’s perspective, it provides a fixed provisional crown on the same day of the extraction and diminishes the number of surgeries needed.
From the clinician’s perspective, it allows us to place an immediate provisional that will support the soft tissue and help preserve the architecture of the gingiva.
Editorial note: The 1-hour webinar, titled “Implant restoration in esthetic zone—immediate, nice and for ever”, will be broadcast live on the Straumann Campus on Thursday, 25 June, at 4:30 p.m. CEST. Attendance is free of charge after registration. Participants will be able to ask questions via a chat window and have the opportunity to earn a continuing education credit by completing a multiple-choice questionnaire on the topic.
