Stratégie des réhabilitations orales concomitantes à une chirurgie orthognatique : prise en charge implanto-prothétique

De nouveaux concepts de planification permettent d’augmenter la prédictibilité du traitement global alliant l’orthodontie, la chirurgie orthognatique et la prothèse. Les processus de chirurgie maxillo-faciale guidée (simulation des déplacements maxillaires), de set up virtuel (anticipation des mouvements orthodontiques) et de planification implanto-prothétique (projet prothétique et chirurgie implantaire guidée) sont nés des nouvelles technologies informatiques et industrielles (empreintes optiques, modèles stéréolitographiques) permettant d’élargir le champ des indications. Le flux numérique, outil de communication, intègre le projet esthétique et fonctionnel global du patient, en facilitant le dialogue transversal. Il met en commun les objectifs thérapeutiques en optimisant le protocole interdisciplinaire et permet de déterminer un calendrier thérapeutique

Strategy for oral rehabilitation concomitant to orthognathic surgery: implantoprosthetic treatment

New planning concepts can increase the predictability of overall treatment combining orthodontics, orthognatic surgery, and prosthetics. Issued from new computer and industrial technology, the process of guided maxillofacial surgery (simulation of orthodontic movements) and implant-prosthetic planning (prothetic projet and guided implant surgery) allow for indications to be expanded. The digital stream, our communication tool, integrates the patient’s overall aesthetic project, facilitates dialogue, pools therapeutic objectives by optimizing interdisciplinary protocol and determines a therapeutic schedule

Vitamin C in Home Parenteral Nutrition: A Need for Monitoring

International audienceTo date, there are no recommendations about screening plasma vitamin C concentration and adjust its supplementation in patients on long-term home parenteral nutrition (HPN). The aim of this study was to evaluate vitamin C status and determine if a commercial multivitamin preparation (CMVP) containing 125 mg of vitamin C is sufficient in stable patients on HPN. All clinically stable patients receiving HPN or an intravenous fluid infusion at least two times per week for at least 6 months, hospitalized for nutritional assessment, were retrospectively included, for a total of 186 patients. We found that 29% of the patients had vitamin C insufficiency (i.e., \textless25 µmol/L). In univariate analysis, C-reactive protein (CRP) (p = 0.002) and intake of only 125 mg of vitamin C (p = 0.001) were negatively associated with vitamin C levels, and duration of follow-up in our referral center (p = 0.009) was positively associated with vitamin C levels. In multivariate analysis, only CRP (p = 0.001) and intake of 125 mg of vitamin C (p \textless 0.0001) were independently associated with low plasma vitamin C concentration. Patients receiving only CMVP with a low plasma vitamin C level significantly received personal compounded HPN (p = 0.008) and presented an inflammatory syndrome (p = 0.002). Vitamin C insufficiency is frequent in individuals undergoing home parenteral nutrition; therefore, there is a need to monitor plasma vitamin C levels, especially in patients on HPN with an inflammatory syndrome and only on CMVP
