Transcrestal sinus lift and implant placementusing the sinus balloon technique

Objective: A description is made of transcrestal sinus lift using the sinus balloon technique, evaluating the bone height achieved and implant success one year after prosthetic loading. Material and method: Between January and July 2007, transcrestal sinus lift using the sinus balloon technique for dental implant placement was carried out in 6 patients. A panoramic X-ray study and maxillary computed tomography scan were carried out before the operation, in order to discard possible sinus pathology. During the intervention, the integrity of the sinus membrane was evaluated using a Medi Pack Pal endoscope (Farol Store and Co., Tuttlingen, Germany), and the intraoperative complications were analyzed. The dental implants were placed in the same surgical step in the presence of 3 mm or more of residual bone. Following the operation, panoramic X-rays were used to assess the bone height gained. One year after prosthetic loading, the implant success rate was determined based on the criteria of Buser. Results: One patient was excluded due to Schneider’s membrane perforation as confirmed by endoscopy. Transcrestalsinus lift was carried out in 5 males with a mean age of 41.6 years (range 27-51), without antecedents of sinus disease. There were no intraoperative complications. In four patients the implants were placed simultaneous to sinus lift, while in another case implant placement was postponed due to insufficient remaining bone height. The mean gain in height after the operation was 8.7 mm. One year after prosthetic loading, the implant success rate was 100% (AU)

The mean gain in height after the operation was 8.7 mm. One year after prosthetic loading, the implant success rate was 100%. CONCLUSIONS: Transcrestal sinus lift using the sinus balloon technique is a minimally invasive procedure. In 5 patients the bone height gained proved sufficient to allow implant placement even in the presence of 3 mm of residual bone.

Hemodynamic and ventilatory changes during implant surgerywith intravenous conscious sedation

Purpose: This study was conducted to determine the hemodynamic and ventilatory changes during implant surgerywith intravenous conscious sedation, and whether preoperative anxiety, gender or age influence these parameters.Patients and Methods: A prospective study carried out between May 2004 and February 2007, on 102 patientstreated with dental implants under local anesthesia and conscious intravenous sedation. Patients completed aquestionnaire prior to surgery to evaluate preoperative dental anxiety using Corah’s scale. The hemodynamic andventilatory changes were evaluated by monitoring systolic pressure (SP), diastolic pressure (DP), heart rate (HR)and oxygen saturation (SaO2). These values were collected at 5 points during surgery; before commencing theoperation (baseline value), during local anesthetic injection, at the moment of incision and raising of a mucoperiostealflap, during implant placement, and finally at suturing. Intravenous conscious sedation was administeredbetween baseline value and injection of the local anesthetic.Results: The highest SP and DP were recorded at baseline and at suturing. The highest HR was recorded at themoment of incision and raising of the mucoperiosteal flap; the lowest SaO2 was recorded at local anesthetic injection.There was no relationship between hemodynamic and ventilatory values and preoperative anxiety or gender.A greater age was associated with higher SP and lower SaO2, these differences being statistically significant.Conclusions: Most of the cardiovascular and ventilatory changes induced by the implant surgery with intravenousconscious sedation were within normal ranges. The results indicate that midazolam with fentanyl do not produceimportant hemodynamic and ventilatory changes, being a good association for intravenous conscious sedation indental implant surgery (AU)
