Unintentional hypotension from lidocaine infiltration during orthognathic surgery and general anaesthesia.

Background: A probable causal relationship between submucosal infiltration of lidocaine, with adrenaline 12.5 microg x mL(-1), and untoward arterial hypotension during general anaesthesia for orthognathic surgery was investigated in two parts.

Methods: The first part of the study was open and non-randomised.

Bone grafting to the maxillary sinus from the lateral side of the mandible.

Patients who were unable to have an implant of the maxilla without a bone graft were operated on by a modified sinus lift method, under local anaesthesia. Cortical bone grafts, harvested from the lateral side of the mandible, were forced horizontally into a slot, made in the lateral sinus wall after a mucosal sinus lift. The immediate stabilization of the graft permitted the dense packing of the space below the horizontal graft with bone chips, which probably contributed to the fast healing of the bone.

Placement of posterior mandibular and maxillary implants in patients with severe bone deficiency: a clinical report of procedure.

The purpose of this investigation was to modify the method for implant placement in the posterior parts of the arches for fixed implant-supported prostheses using minimally invasive surgery. Eighty-six implants were placed posterior to the mental foramina in patients with severely resorbed mandibles, and 75 implants were placed in the posterior severely resorbed maxilla. Bone grafting from the mandible to the maxillary sinus was performed in 9 patients with severely atrophic maxillae.

Tilting of posterior mandibular and maxillary implants for improved prosthesis support.

Rehabilitation of atrophied edentulous arches with endosseous implants in the posterior regions is often associated with anatomic problems such as jaw shape and location of the mental loop, mandibular canal, and maxillary sinuses. The purpose of this investigation was to modify the method for implant placement in the posterior part of the jaws to extend fixed implant-connected prostheses further distally, and to reduce the length of cantilevers in complete-arch prostheses without transpositioning the mandibular nerve or performing bone grafting in the maxilla. Forty-seven consecutive patients were treated with implants (25 patients/36 mandibular implants, 22 patients/30 maxillary implants) placed in tilted positions.

Effects and adverse events of a dental appliance for treatment of obstructive sleep apnoea.

In a prospective study, 95 patients with mild to moderate obstructive sleep apnoea (OSA) were randomised to receive either surgical treatment, uvulopalatopharyngoplasty, (4-6 patients) or treatment with a nocturnal dental appliance for mandibular advancement (49 patients). Of the 49 dental appliance patients, 37 completed the 12-month follow-up. The aim of this study was to evaluate the effects and adverse events of dental appliance treatment from a one-year perspective.
