Full and partial dentures are still a popular way to restore wholly or partially edentulous patients who do not wish to have dental implants or who are unsuitable for treatment. An accurate denture impression can ensure your restoration will achieve three critical factors:
Excellent margins are essential for achieving a well-fitting restoration requiring minimal chair-side adjustments. It is crucial to ensure the margins are designed and prepped correctly, and afterward, it is best to polish your prep. Your choice of margin preparation depends on the type of crown selected for the patient. The types of margins and when to use them are outlined below.
The number of Zirconia crowns fabricated annually now exceeds PFM crowns. With this trend likely to continue, it is crucial to know how best to place zirconia crowns. Often, the fit and appearance of a crown can be enhanced by making a few simple changes.
Surgical guides allow doctors to plan an implant virtually and then accurately place an implant in the most safe, predictable, and efficient manner. In addition to increased accuracy, patients will also save chair time.
The total edentulous population worldwide is approximately 6-10%. The demand for implant-supported prostheses is anticipated to expand considerably over the coming years for several reasons, including the aging baby boomer population.
An excellent quality dental impression is critical, because without it the dental lab cannot fabricate accurate, well-fitting restorations. Ideally, potential dental impression errors should be identified before the impression is sent to the lab. Otherwise, work may be delayed if the impression is rejected.

It isn’t unusual for clinicians to regularly see patients who have clinical failures or complications related to poor occlusion. Complications can cause pain, compromise masticatory function and affect patients’ phonetics and appearance.
Shade matching is subjective and influenced by many different factors. An inaccurate shade is a common cause of remakes, as even the slightest difference between an actual shade and its perceived color makes a huge difference in the mouth and is unacceptable to the patient and clinician. Being aware of issues that can affect your perception of color, and knowing how to reduce their influence, allows you to take more accurate shades.
