CAD/CAM Anterior and Posterior Implant Restorations - Ceramics, Abutments and Design CAD/CAM Anterior and Posterior Implant Restorations - Ceramics, Abutments and Design

Summary:

Fabrication and design of implant abutments has been previously published. Using CAD/CAM software to design the final abutments has also increased precision of designs and decrease in laboratory fabrication times. The specific design programs require information from the clinician to better understand each specific tooth emergence for each site. Using radiographs, tissue bio-types and algorithmic equations, the design technician together with the clinician can better design the final contours and emergence that is necessary for ideal tissue support and long term tissue stability. The use of intra-oral digital acquisition units can also help the fabrication of CAD/CAM restorations that follow the emergence from the abutment to the final restoration. Using a coded healing abutment such as Encode® (Biomet 3I, Palm Beach Gardens, FL.) can further facilitate the transfer of digital information from the clinical environment to the laboratory, in a matter of minutes. In addition, the digital scan of the occlusal relationships are more precise and accurate than any stone casts. The use of in-office CAD/CAM techniques will be highlighted to fabricate implant posterior and anterior implant crowns. The new monolithic and feldspathic ceramic blocks can be utilized to fabricate life-like color and translucency as well as fit and marginal integrity. Computerized and CAD/CAM prosthodontic care of our patients can be more efficient, more predictable and save chair time for our patients.

The “Scalloped Guide”: A Proof-of-Concept Technique for a Digitally Streamlined, Pink-Free Full-Arch Implant Protocol
Inadequate restorative space can result in mechanical, biologic, and esthetic complications with full-arch fixed implant-supported prosthetics. As such, clinicians often reduce bone to create clearance. The aim of this paper was to present a protocol using stacking computer-aided design/computerassisted manufacturing (CAD/CAM) guides to minimize and accurately obtain the desired bone reduction, immediately place prosthetically guided implants, and load a provisional that replicates predetermined tissue contour. This protocol can help clinicians minimize bone reduction and place the implants in an ideal position that allows them to emerge from the soft tissue interface with a natural, pink-free zirconia fixed dental prostheses.

Treating Two Adjacent Missing Teeth in the Esthetic Zone - Part 1: The Pink Hybrid Restoration & the Unilateral Versus Bilateral Defect Concept
This article, the first of a planned three-part series, outlines a new surgical & prosthetic approach for treating cases involving two missing adjacent teeth in the esthetic zone. These type of cases, particularly when combined with a three-dimensional ridge deficiency, represent one of esthetic dentistry's most challenging dilemmas. A Clear understanding of the unilateral and bilateral defect concept is necessary to properly evaluate each particular case, understand surgical limitations, perform a better risk assessment, establish an esthetic prognosis, develop the best clinical-laboratory strategy, and adjust patients' expectations. While not recommended for every case, represents a useful, economical, and predictable alternative that decreases the umber and complexity of interventions.
