Impressions for implant restorative dentistry is divided into two main methods for the restoring of fixed prosthodontic restorations i.e. indirect, which utilize various types of transfer copings with laboratory analogs and direct, which utilize standard crown and bridge methods that are used with natural teeth. Users of the Tatum implant system, which uses the direct approach, are familiar with the many advantages the system offers our patients such as no subgingival microgap, no set screws to loosen, and one of the strongest implant/post connections. In addition to these advantages the Tatum implant system offers the restorative dentist the opportunity to complete these implant cases very much like any other tooth borne restorative case. No transfer pins, abutments and separate sets of temporary restorations are required. Producing high quality master models that replicate the soft tissues, surrounding teeth and implants has been standard fare with dentists for many years. However, producing master models with implants do offer some unique challenges for the dentist and laboratory technician. Stone models while accurate are known to be brittle and often require multiple pours during the fabrication of a complete case. Poured epoxy or other resin models produce stronger models but often tend to introduce polymerization shrinkage inaccuracies adding complexity to long span or multi-unit cases. Problems with model breakage can be a big source of additional chairtime when multiple try-ins must be made to insure the accuracy of fit for complex restorations. During the past 18 to 20 months, I have had the opportunity to restore both natural teeth and implants with the Cadent iTero digital impression system. The iTero system actually is more than a different impression method in that it combines an opposing arch impression and digital bite registration at the same time. Models for individual restorations, multiple splinted units and long span bridges are all within the unit’s capabilities. The entire model (base and dies) is made of a durable and dimensionally stable resin material that resists fracture and wear, an especially desirable attribute for the often narrow and long implant preparations. The use of the iTero impression system can be demonstrated with the following Tatum implant case for the replacement of several missing and non-restorable lower molars.

The patient needed both lower second molars removed with implants to replace teeth in the #19, #30 and #31 place. Upon sectioning of the existing fixed bridges and the second molar removals, an immediate implant place-ment was to be utilized in the extraction socket of #31 with simultaneous placements in the previously healed pontic areas of #30 and #19. Tatum Tapered Implants of 5mm X 17mm was chosen for the first molars and a Tatum Tapered 6mm X14mm was chosen for the second molar. The extraction socket was degranulated and decorticated and all implant sites prepared with the Tatum Step Drills. Socket voids were filled with demineralized bone matrix in the more apical areas and surgical plaster was placed around the more superficial area adjacent to the smooth collar. All implants were placed following the usual procedures for positioning and torque forces.

Following three months of healing radiographs were taken, abutments cemented and prepared. Full mouth digital impressions were made of the implants, surrounding teeth and opposing arch. Digitally a centric bite registration was also made. The iTero system does not require any powder or additional contrast medial to be placed on the areas to be scanned. This is a very significant factor in choosing an impression method for implants. The ability to successfully capture marginal detail well below the soft tissue crest is vital when restoring implants. Standard impression cord techniques have proven themselves with this system. After preparation each abutment post is lightly blasted with an intra-oral microetcher to aid in cement retention and provide a matte surface to reduce any shiny glare that might interfere with scanning.

Individual dies produced are solid and fit in the computer created “socket” very snuggly. The pin-like extension is solely for ease of die removal as the dies are actually pinless owing their snug fit and orientation to the outline and minor taper of their bases. The overall effect is to have a base and pins so rigid as to give the laboratory technician a model to work with that feels much like a “solid model” that has no removable dies with all the advantages of removable dies. The resin ma-terial that the dies and base are made of offer a wear resistant, smooth finish. The overall net effect is that the completed res-torations require fewer proxi-mal and occlusal intraoral ad-justments at final delivery.

Various views are allowed to outline margin placement for the restorations. These screen shots have the “marginal ditching” turned on to further enhance or accentuate the marginal outline. Models produced from the oral scans:

Overall, the use of CAD/CAM generated models for fixed prosthodontics have made it easier to provide nice final restorations because of the following advantages:

» Easier impressions. No remakes for slight marginal areas missed. Simply take additional scans of the area until all the desired detail is captured. » More stable removable dies. » Greater wear resistance and die brittleness. » The ability to work with only one model. No removable die model and another solid model. » Accurate centric occlusion bite registrations.

Whenever more complex c a s e s t h a t i n v o l v e re-establishing anterior guidance or the use of study models for developing more complex occlusal needs the iTero models can be easily placed on semi or fully adjustable articulators as needed.
