PROVISIONAL RESTORATIONS IN RESTORATIVE DENTISTRY

Provisional restorations are of a great significance in fixed prosthodontic rehabilitation, particularly in case long-term treatment is needed before final prosthetics. The restorations are also important from the point of view of diagnosis and treatment plan assessment so they should be similar to the final constructions in their shape and function. Provisional restorations quite often need alterations and adjustment to the new requirements, so it’s important to comprehend the compositional properties of the base and repair materials to make a reliable bond between them. Thus, interim treatment should meet a number of requirements such as biocompatibility, marginal adaptation, strength and longevity. The purpose of this review is to discuss fabrication technology of provisional restorations, possible failure and complications, the ways to correct them as well as the aspects of relining provisional restoration.Provisional restorations are of a great significance in fixed prosthodontic rehabilitation, particularly in case long-term treatment is needed before final prosthetics.

CEMENT SELECTION IN DENTAL PRACTICE

The cementation procedure is considered to be the most important stage of fixed prosthodontics, while the correct selection of cement is the guarantee of successful restoration which is conditioned by the its durability. Over the recent years, numerous cementing substances have been introduced to the dental practice that differ greatly from conventional cements with their properties and application methods and that is why even experienced dentists often have certain difficulties in the variety of cements to choose the one that is right for each clinical case. The selection of cement depends on a number of factors, such as the type of resorption substance, the shape of prepared tooth, the possibility to isolate the area, subject to cementation in the oral cavity as well as the patient’s aesthetic requirements. Thus, the objective of the article is to analyze currently used dental cements in order to help the dentists make the right selection of cement for different clinical cases.The cementation procedure is considered to be the most important stage of fixed prosthodontics, while the correct selection of cement is the guarantee of successful restoration which is conditioned by the its durability.
