BACKGROUND: Single-tooth replacement often requires a prefabricated dental implant and a customized crown. The benefits of individualization of the abutment remain unclear. PURPOSE: This randomized controlled clinical trial aims to study potential benefits of individualization of zirconia implant abutments with respect to preservation of marginal bone level and several clinical and patient-based outcome measures. MATERIAL AND METHODS: Fifty participants with a missing premolar were included and randomly assigned to standard (ZirDesign, DentsplySirona Implants, Mölndal, Sweden) or computer aided design/computer aided manufacturing (CAD/CAM) customized (Atlantis, DentsplySirona Implants, Mölndal, Sweden) zirconia abutment therapy...

The prosthetic restoration of implants to obtain an esthetically balanced outcome is an extremely complex process--especially in terms of effective soft-tissue management. So-called hybrid abutment crowns, which can be made from polymer milling blocks in an uncomplicated process and used for immediate provisional restoration, represent an advance in the efficient production of superstructures.

Parallel use of implant treatment planning software and cone-beam computed tomography (CBCT) can, using certain criteria, consolidate steps and streamline tooth replacement strategies. The authors describe such a case in the esthetic zone whereby flapless extraction and immediate implant placement using CT-guided surgery were performed simultaneously, with placement of a computer-aided design/computer-aided manufactured (CAD/CAM) patient-specific abutment and non-occlusal function provisional in a single visit (supporting the "one-abutment, one-time" concept)...

STATEMENT OF PROBLEM: Computer-aided design and computer-aided manufacturing (CAD/CAM) generated restorations are gaining popularity. However, limited clinical evidence is available for single-unit posterior CAD/CAM restorations fabricated with established and newer crown materials. PURPOSE: The purpose of this clinical study was to assess the restoration quality of and gingival response to CAD/CAM fabricated posterior single-tooth restorations with different processing technologies...

The role and function of provisional restorations has changed significantly in recent years. The reasons include the improvement of material properties and the CAD/CAM production option using polymer blanks, which are offered by various manufacturers. Besides their classic indications in crown and bridge prosthodontics, provisional restorations are now used for soft-tissue management, preparation and adaptation in complex restorations that include changes in vertical relations, and as mock-ups in esthetic dentistry...

Well-placed dental implants are a prerequisite of functional and esthetically successful dental implant-supported crowns. The presence of soft tissue is essential for excellent esthetics because the dental implant or titanium abutment may become visible if the soft-tissue contour is not acceptable. This clinical report describes the use of a custom ceramic implant abutment designed with computer-aided design and computer-aided manufacturing (CAD/CAM) technology by milling a zirconia framework that was cemented extraorally to a prefabricated titanium abutment with a reduced diameter...

In order to use CAD CAM (Computer Aided Design, Computer Aided Manufacturing) technology as an assessment tool when evaluating the preclinical performance of dental students, it is imperative that one has confidence in the reliability of the process. In this study, a variety of alignment methods were compared to determine both the consistency and accuracy of each method. Although the "Tooth Dots Diagonal" method exhibited the best precision (coefficient of variation=5.4 percent), it also represented the least accurate method when compared to the other methods tested...

PURPOSE: To introduce a method applied in computer aided design and computer aided manufacture (CAD-CAM) of template for crown lengthening. METHODS: Point cloud data of dental stone model of the patient in the plan of crown lengthening surgery was obtained by laser scanning. The following processes were carried out, constructing 3-D curve of the gingiva, drawing template outline on the triangle mesh model, shelling it for 3-D model of template, and transferring the data to rapid prototyping equipment for manufacture...

OBJECTIVE: Even with beautifully done restorations, an unattractive gingival zenith position, can negatively affect the smile of a person. In this short communication we describe the treatment of a rotated maxillary right central incisor using a digital photographic approach instead of the conventional approach. BACKGROUND: The conjecture literature on prosthodontic considerations and gingival zenith position in cases of rotated maxillary central incisors is sparse...

The aesthetic rehabilitation of patients with functionally compromised dentition frequently involves a multidisciplinary approach. A correct aesthetic diagnosis, treatment plan, and careful material selection are critical factors in successful restoration. A team approach that includes the clinicians, the laboratory technician, and the patient is essential to achieve the desired result. The following case presentation demonstrates a successful multidisciplinary approach used to recreate an aesthetic smile in a young patient with functionally and aesthetically compromised anterior maxillary dentition...

PURPOSE: Adhesive cementation reduces the need for macroretentive preparation for crowns. This study investigated the survival and clinical rating of monolithic computer-aided design/manufacturing (CAD/CAM) ceramic crowns bonded to preparations with reduced macroretention, hypothesizing that adhesion would compensate for reduced retention geometry. MATERIALS AND METHODS: Two-hundred eight posterior CAD/CAM-generated crowns from feldspar block ceramic were adhesively bonded in 136 patients in three preparation groups: classic (100% stump height, n = 70); reduced (reduced stump height or irregular stump, n = 52); and endo (absent stump but pulp chamber retention cavity, n = 86)...
