Risk assessment, biological contamination and the PDCA cycle

29 May 2023

Biological risk in the workplace, with a few exceptions that might include healthcare settings or diagnostic and research laboratories, is undeniably attributed less importance than other occupational risks, and it can be little known or overlooked, especially for outdoor work activities. Yet no workplace can be considered exempt from this risk, since biological agents are […]

The importance of study models in treatment planning

29 May 2023

Dental models are positive reproductions of a patient’s intraoral situation. (1) They can be fabricated using either the conventional technique, by casting gypsum inside an impression, or a CAD/CAM digital technique, by milling or 3D printing. (2) Depending on how they are used, Models can be divided into two families (1, 3, 4): Let’s focus […]

Impressions for functional orthodontic appliances

8 May 2023

Dental impressions are negative reproductions of the teeth and adjacent structures. (1) The more adjacent structures an impression records, the greater the extent of the impression will be. The extent of an impression is therefore a physical-anatomical-volumetric characteristic.

The advantages of automatic mixing for alginate preparation

3 February 2023

Alginate is the most commonly-used impression material in dental practices [1]. Its uses range from the fabrication of study and antagonist models to the fabrication of work models for orthodontics [2]. Alginate, which has been developed since the 1930s, is a material belonging to the irreversible hydrocolloid category. Its main advantages are its low cost, […]

Alginates for orthodontics: the characteristics that cannot be missed

Let’s take a look at them. h2. Background: the purpose impressions serve in orthodontics In orthodontics, impressions are usually taken for two reasons: Impressions are used to […]

Custom-made endodontic posts, impressions and fabrication techniques

3 February 2023

Devitalised teeth are generally teeth that have lost much of their coronal structure as a result of decay processes, fractures or the magnitude of the endodontic access cavity. In these cases, in order to restore structural integrity, a number of different root canal retention systems or endodontic posts have been used with success. (1) Endodontic […]
