RESUMO
A 57-year-old man presented with mesial inclination of the lower right first molar caused by untreated loss of the second premolar. The occlusal relationship was restored by dental implant treatment following improvement of the intraoral environment by orthodontic therapy. At his initial visit, the interdental spacing in the molar-premolar region was inadequate, as the first molar had mesially inclined into the extraction space of the second premolar. The patient had also lost the second molar and complained of masticatory problems on the right side. It was considered necessary to restore the second molar and improve the occlusal relationship with the first molar to recover occlusal function on the right side. After orthodontic therapy to correct the position of the mesially inclined tooth, occlusal restoration was carried out by dental implant treatment. The patient's clinical condition has remained excellent at over 5 years 2 months post-surgically and the patient is satisfied with the treatment outcome. The combination of dental implant treatment and orthodontic therapy were effective in improving the intraoral environment in this patient, indicating the efficacy of interdisciplinary treatment planning and practice.

PATIENT: A 67-year-old female with root fracture of the maxillary central incisor underwent implant placement immediately after extraction, with the goal of shortening the treatment period. The superstructure was placed on the implant after a 4-month healing period. Review 5 years after implant loading revealed no clinical problems. DISCUSSION AND CONCLUSION: The treatment time was shortened effectively by the flapless immediate post-extraction placement procedure. Immediate post-extraction implant placement based on proper examination and diagnosis would reduce the patient burden.

PURPOSE: The purpose of the present study was to determine whether intravenous sedation during dental implant surgery contributed to stabilization of hemodynamics. MATERIALS AND METHODS: Two hundred fifty-five consecutive patients treated with dental implants were randomly assigned to receive either intravenous sedation with local anesthesia (sedation group, n = 123) or local anesthesia only (nonsedation group, n = 132). Midazolam and propofol were used synergistically as sedative agents. Systolic blood pressure, diastolic blood pressure, and pulse rate were measured every 2.5 minutes during dental implant surgery. On the basis of these data, the coefficient of variation, percentage of change, maximum values, and incidences of a larger increase were analyzed and expressed as cardiovascular changes. RESULTS: A comparison of percentages of change, maximum values, and incidences of a greater increase showed that systolic and/or diastolic blood pressure were significantly higher in the nonsedation group than in the sedation group. The combination of midazolam and propofol sedation prevented excessive increases in blood pressure. The circulatory suppression induced by the intravenous sedation regimen not only reduced mental stress arising from the state of sedation but also exerted a pharmacologic effect. The application of this intravenous sedation regimen stabilized hemodynamics and contributed to the safety of the patient in dental implant surgery. CONCLUSION: The application of intravenous sedation had a beneficial effect for hemodynamic changes during dental implant surgery.

A 60-year-old man with missing maxillary molar teeth received dental implant therapy for reconstruction of occlusion. Sinus floor elevation with autogenous bone graft consisting of iliac bone block and particulate cancellous bone and marrow (PCBM) was performed in the bilateral maxillary sinuses for implant placement. On the right side, bone height in the molar region was less than 2mm. Therefore, a delayed protocol was applied, and 2 implants were placed 4 months after bone grafting. Bone graft resorption occurred during the healing period of 4 months. On the left side, 3 implants were placed simultaneously with sinus floor elevation, as bone height in the molar region was more than 4-5mm. The bone graft was carried out at the same time as implant placement. After implant placement, resorption of the bone graft stopped, and the superstructures were delivered on both sides. The tissues around the implants were clinically healthy at one year after examination. Sinus floor elevation with autogenous bone graft is an acceptable option for implant treatment in the maxillary molar region where there is adequate height of existing bone. In postoperative care, it is important to undertake adequate follow-up to ascertain occurrence of bone graft resorption.
