Evaluation of marginal fit of CAD/CAM restorations fabricated through cone beam computerized tomography and laboratory scanner data.

Statement Of Problem: Whether cone beam computed tomography (CBCT) images can be used for the fabrication of computer-aided design/computer-aided manufacturing (CAD/CAM) restorations is unknown.

Purpose: The purpose of this in vitro study was to evaluate the marginal fit of CAD/CAM restorations fabricated by using data from CBCT scans with 3 different voxels and laser scanner images.

Material And Methods: A crown preparation was made on an extracted premolar tooth according to ceramic crown preparation guidelines.

Stabilization of a computer-aided implant surgical guide using existing dental implants with conversion of an overdenture to a fixed prosthesis.

This clinical report describes a technique to stabilize a computer-aided dental implant surgical guide to existing implants. A patient requested conversion of her existing mandibular implant-assisted overdenture into a fixed complete denture. The surgical procedure was planned virtually, and the two existing dental implants were integrated into the surgical plan as a means to fixate the surgical guide.

Flapped or flapless surgery for narrow-diameter implant placement for overdentures: advantages, disadvantages, indications, and clinical rationale.

Narrow-diameter implants for overdenture applications have gained in popularity due to their ability to be placed with simplified and less traumatic surgical protocols in limited-width alveolar ridges. The decision of whether to use a flapped or flapless procedure must be guided by a thorough evaluation and evidence-based diagnosis. This article reviews current principles relating to the use of narrow-diameter implants, along with the advantages and disadvantages of current surgical protocols.

A technique for fabricating a hinged mandibular complete dental prosthesis with swing lock for a patient with microstomia.

Microstomia is defined as an acquired or congenital condition involving a reduction of the oral aperture severe enough to compromise esthetics, nutrition, and quality of life. This clinical report describes a technique for fabricating a mandibular swing-lock complete denture with a hinge for a patient with muscular dystrophy. A hinge in the midline allowed the denture to collapse.
