    Efectos de los analgésicos antiinflamatorios no esteroideos en la oseointegración de los implantes dentales. Revisión de Alcance
    (2019) Paula C. Baralt Bracho; Silvio J. Saba Salami; C S Ruthmary Parra
    The purpose of this Scoping Review of the literature was to determine whether the postoperative or chronic administration of non-steroidal anti-inflammatory analgesics drugs (NSAIDs) decreases the osseointegration of dental implants. An electronic literature review was made using the Medline (PubMed) and Science Direct databases, selecting articles between January 2006 and January 2018. The keywords used were: nonsteroidal anti-inflammatory drugs (NSAIDs), osseointegration, dental im- plants. The inclusion criteria included research on the effects of NSAIDs on the osseointegration of dental implants in animals, in humans and retrospective studies. The search yielded 868 articles of which 11 were selected. The retrospective studies showed discrepancies since they showed an association between the preoperative ingestion of NSAIDs and the failure of osseointegration as well a tendency to increase the bone crest around an implant with the consumption of NSAIDs. The studies in animals showed that the activity of cyclooxygenase 2 (COX-2) plays an essential role in osseointegration, so the specific inhibitors of COX-2 could be avoided preoperatively and postoperatively. The administration of ibuprofen did not affect the healing of dental implants and could be administered as postoperative medication in doses of 600 mg, 4 times a day for a week. It was also shown that the administration of aspirin produced no adverse effects and could increase the osseointe- gration rate. However, NSAIDs administered chronically could cause a negative effect on osseointegration.

    Registros intermaxilares en pacientes edéntulos bimaxilares con técnicas convencional y digital. Serie de casos
    (2020) Silvio J. Saba Salami; N Cova; R Lorena Bustillos
    In prosthetic rehabilitation of the bimaxillary edentulous patient, the recording of intermaxillary relationships determines a critical stage in the success of the treatment and influences the aesthetics and functioning of total prostheses. To obtain the intermaxillary records, bite wax rims are usually used (conventional TC technique), and for total prostheses made with CAD-CAM technology the intermaxillary records are obtained with trays equipped with an intrabuccal tracer (TD digital technique). The objective of this research is to compare conventional and digital techniques in the taking of intermaxillary records by means of Ricketts’ cephalometric analysis. The study is a series of cases, consisting of five totally edentulous patients aged between 61 and 90 years. Two intermaxillary records were made for each patient, one for conventional technique and another for digital technique, accompanied by a lateral cephalic radiography with each one of the registers placed in the buccal cavity, to obtain the lower facial height (AFI) and the facial convexity (CF) of Ricketts. The results obtained showed that there is little variation between the methods used. The mean CF was -0.4 mm ± 2.88 on the CT and -1.0 mm ± 2.55 on the TD, while the mean of AFI was 41.6 ° ± 4.45 on the CT and of 41.4 ° ± 5.59 on the TD, by which both can be used reliably in the dental practice.
