Infected Silicone Chin Implant After Implant-Supported Jaw Rehabilitation: Case Report and Literature Review.

This paper reports on an infected silicone chin implant due to the nonideal placement of dental implants, in a female patient aged 67 years old. A patient unsatisfied with her facial profile had received a silicone chin implant 25 years ago and had recently undergone surgery for placement of dental implants in a region close to the silicone implant. The nonideal positioning of dental implants and close contact with the silicone implant led to the absence of osseointegration, with consequent mobility and infection of both.

Oral Rehabilitation With Dental Implants and the Importance of a Preventive Evaluation for Osteonecrosis of the Jaws Associated With Medications.

Osteonecrosis of the jaw is a possible oral complication resulting from antiresorptive therapies, such as bisphosphonates (Bfs). Although the etiology is not entirely clear, it has been shown to be dependent on several factors, with the traumatic stimulation caused by the placement of teeth implants indicated as one of the predisposing factors to this pathology. The indications and preventive methods for performing these procedures have been questioned, making it essential to determine the proper protocols.

Osteopromotion Capacity of Bovine Cortical Membranes in Critical Defects of Rat Calvaria: Histological and Immunohistochemical Analysis.

Membranes that aid the guided bone regeneration (GBR) process have been the subject of studies of compatible biomaterials that contribute to this repair process. The present study compared different membranes used in critical-size defects of rat calvaria by assessing GBR as well as histological, histomorphometric, and immunohistochemical reactions. Forty-eight male albino Wistar rats were randomly allocated into four groups ( = 12 each), namely, C: membrane-free control group (only blood clot, negative control group); BG: porcine collagen membrane group (Bio-Gide®, positive control group); GD: bovine cortical membrane group (first experimental group); and GDF: thicker bovine cortical membrane group (second experimental group).

Use of osseointegrated implants in the intermaxillary suture in a patient with microstomia: Case report with a 2-year follow-up.

Aim: To report the rehabilitation of a female patient, 40 years old, with a microstomia.

Case Report: The Z-plasty surgery was performed in the region of the labial commissure to increase the mouth opening. In the mandible, two implants were installed in the interforaminal region and an overdenture with bar/clip attachment system was made.

Assessment of Valeriana officinalis l. (Valerian) for Conscious Sedation of Patients During the Extraction of Impacted Mandibular Third Molars: A Randomized, Split-Mouth, Double-Blind, Crossover Study.

Purpose: The objective of the present study was to evaluate the effectiveness of an herbal drug (valerian) to control anxiety during mandibular third molar extraction compared with a reference benzodiazepine drug commonly used in dental procedures (midazolam).

Materials And Methods: Twenty anxious patients with an indication for bilateral extraction of mandibular third molars were selected. The patients received capsules containing valerian 100 mg or midazolam 15 mg orally 60 minutes before the procedures in a randomized, split-mouth, crossover design.
