Lava Cos, Digital Impressions And Work Flows
Intraoral scanners are currently popping up in many dental practices. It has become obvious through the manufacturing of thousands of restorations from digital impressions, that there are many advantages when compared to the analog approach. One of the more significant advantages of digital impression systems is that they will provide laboratories and doctors with innovative and integrated digital work flow solutions. In addition, many outstanding materials require digital manufacturing. Thus, digital impressions are the gateway to the digital work flow.
The digital workflow can begin by the taking a digital impression. The electronic file travels to the lab, where a technician uses software to perform virtual model and die work. This includes, setting the bite plane, cutting out the dies and defining the margins. Next, the electronic file goes through some digital post processing and subsequent model and die fabrication. Model manufacturing is currently performed by the milling of models from a block as well as the additive process known as SLA, sterolathography (no more conventional M&D fabrication). Once the virtual modes have been post processed, simultaneous manufacturing of the final restoration can begin. A laboratory can complete CAD CAM process immediately. CAD design and automated manufacturing does not require the initial completion of models and dies. Once the models and other digital crown parts are fabricated, all parts are merged, finalized and put through quality control processes. Please keep in mind, digital impressions also support all conventional analog approaches for crown fabrication.
In conclusion, a digital workflow is a seamless, more efficient, less labor intense manufacturing process for both dentists and labs. Restorations become more consistent, with improved quality. There is no question; digital work flows reduce cost resulting in greater profits for dentist and laboratory owners alike; ultimately providing higher quality care with greater ease.
Why are Digital Impressions more accurate?
Digital impressions have proven to be far more accurate than the conventional analog approach. The primary reason for this is the elimination of many potential problems that occur during the analog impression procedure. Some of the errors that are routinely found in conventional method and are a nonfactor when taking a digital impression are as follows:
- Movement of tray
- Tearing of impression material
- Inadequate adaptation of the impression material to the dental anatomy
- Bubbles & voids
- Distortion from patient movement
- Disinfection of non-PVS materials
- Deflection of the tray
- Inadequate Adhesive
- Lack of tray support (overhanging material)
In addition to eliminating all of the very common problems above, digital impressions also eliminate some chemical based processes. All analog impressions are a chemical based procedure. When impressions set, there is an expansion of the material. The chemical based process of pouring a stone model also contains inaccuracies as the stone has a measurable setting expansion as well. When taking a digital impression all of this is eliminated.
Data acquired by 3M on the Lava COS confirms a dramatic increase in accuracy when using the Lava COS. Historically, dental labs report 3-4% of the work they produce results in a remake. When using the Lava COS, this number is reduced to less than .5%. In addition, dentists report an average of 41% reduction in chair time for the insertion appointment. The digital impressions and models are routinely far more accurate than the conventional approach.
The Lava COS also obtains a centric occlusion record. Historically, dentists would place material between the patient’s teeth and have them close. The objective was to obtain a record of maximum intercuspation. From a logical point of view, why would we want material between maxillary and mandibular teeth if we are attempting to record maximum intercuspation? When going digital, there is a simple scan of the labial surfaces of a patients teeth while they are closed and in centric occlusion. There is no need for any material between the teeth. This is a contributing factor to reduced chair time at insertion appointments. Dentists are reporting crowns that require considerably less chair side adjustment. In conclusion, the Lava COS is a great advancement in dental impression procedures.

Landscape ideas for the patio covered with moss?
I have a section of my backyard is mostly dirt does not get any sun and tends to moss. Should I reseeding to get the grass growing back there? Or should I consider establishing small stones or red lava rocks back there? Drainage not is good at this stuff, but I'm not looking to make any major drainage work, just something quick that will make the moss out and write something that looks good. Thanks for your suggestions. I like red lava rock and white pebbles.
try ferns, hostas, astilbe, and let the moss grow on and around it. All in the shade over product and moisture conditions. I always recommend working with the conditions they have instead of trying to spend a small fortune to change things. Grass will never do well in acid soil and shade all. Hope this helps.
