Accuracy of a flapless protocol for computer-guided zygomatic implant placement in human cadavers: expectations and reality.

Background: This work evaluated the accuracy and safety of a protocol for minimally-invasive flapless zygomatic implant placement that uses computer-guided stereolithographic mucosa-supported surgical templates.

Methods: A total of six zygomatic implants were placed in three formalin-fixed human cadaver heads, with edentulous and severely atrophic posterior maxillae. CT scans of each cadaver head were performed after zygomatic implant placement, to evaluate the lateral error (LE) at implant tip and base, and the angular error (AE) of the implant body.

Zygomatic implant placement with flapless computer-guided surgery: a proposed clinical protocol.

Purpose: The aim of the present report is to describe a procedure for zygomatic implant placement using image-guided implant surgery. This is an innovative technique and includes a new clinical approach to provide the direction to guide drilling.

Materials And Methods: The ethical committee of the University of Genoa approved the study.

Accuracy of computer-aided oral implant surgery: a clinical and radiographic study.

Purpose: Computer-aided oral implant surgery offers several advantages over the traditional approach. The purpose of this study was to evaluate the in vivo accuracy of computer-aided, template-guided oral implant surgery by comparing the three-dimensional positions of planned and placed implants.

Materials And Methods: Oral implant therapy was performed in two treatment centers on eligible patients using computerized tomography (CT)-based software planning and computer-aided design/computer-assisted manufacture stereolithographic templates.

Maxillary single-tooth replacement utilizing a novel ceramic restorative system: results to 30 months.

This study reports on the first longitudinal results of an alumina (70%)-zirconia (30%) ceramic restorative system for implant-supported, single-tooth replacement in the anterior maxillary jaw. Eighteen patients (9 men, 9 women, mean age = 42.4 years) were treated with 22 implants placed into 19 extraction sockets and 3 residual ridges.

Single-tooth implant restorations in the esthetic zone with PureForm ceramic crowns: 3 case reports.

The anterior maxillary jaw is frequently called the "esthetic zone" because of its high visibility and influence on facial appearance. Implant placement and single-tooth restoration in this region can present some esthetic challenges for the clinician. The underlying titanium abutment, for example, can diminish porcelain translucency and result in a darkened prosthesis.

Immediate tooth extraction, placement of a Tapered Screw-Vent implant, and provisionalization in the esthetic zone: a case report.

Purpose: This clinical report describes an immediate tooth extraction, followed by placement and provisional restoration of a dental implant in the prepared socket of a right maxillary central incisor.

Materials And Methods: The tooth was extracted with minimal hard and soft tissue trauma and without flap reflection. A flapless, transmucosal surgical approach was used to prepare the socket and insert a tapered implant.
