[New protocol combining orthodontics and implant therapy for partially edentulous adult patients. Part I: Description of the Decker protocol]. / Nouvelle approche de la thérapeutique ortho-implantaire de l'adulte partiellement édenté. Partie I : description du protocole Decker.

INTRODUCTION: The treatment of adult malocclusion is usually complex and pluridisciplinary. Its prognosis is not reliable. We present a new clinical protocol to improve the management and final result. TECHNICAL NOTE: We use a specific software (Simplant®, OMS®, Materialise Dental) and its accessory modules. It allows visualization of the expected final clinical result of the orthodontic treatment. Combined with guided-surgery, it allows placing implants at the beginning of treatment in a position that is compatible with the final position. The implants serve as absolute anchorage for dental motions during the orthodontic step; it is also used to support the final prosthesis. The treatment is thus optimized and its prognosis is improved. Finally, the reversed surgical sequences shorten the treatment thus promoting the compliance of patients.

[Unconventional transradicular implant placement to avoid invasive surgeries: toward a potential paradigm shift]. / Protocole non conventionnel de mise en place d'implants transradiculaires. Esquisse d'un changement de paradigme.

The authors had for aim to present a new minimally-invasive protocol to rehabilitate anterior maxillary edentulism due to an impacted tooth. The implant is placed without removing the impacted tooth, which intercepts the implant trajectory. The inclusion/exclusion criteria have not been defined yet but this protocol goes against the consensual concept that no implant surface other than implant-bone interface should be tolerated. New implant-tissue interfaces are created in addition to the usual one, but this does not seem to jeopardize the prognosis of implants. The risk analysis shows that there is a growing corpus of reliable clinical and histological data to support this unconventional protocol. The overall follow-up covers from a 6-month to an 8-year period. This protocol should be more broadly documented before it can be used routinely; nevertheless it suggests that some of the leading concepts in dental implantology may be revisited.

[Computer-assisted implantology]. / Implantologie assistée par ordinateur.

We had for aim to present the three applications of computer-assisted implantology: preoperative exploration of the surgery site, guided surgery, and preparation of the temporization prosthesis before surgery. Cases are presented for each indication and their clinical relevance is discussed.
