Importance of an Evaluation Phase When Increasing the Occlusal Vertical Dimension: A Systematic Review.

Objective: To assess whether an evaluation period is necessary for patient and clinical success when increasing the occlusal vertical dimension (OVD) for a full mouth rehabilitation.

Materials And Methods: A systematic search was conducted in six databases: MEDLINE, Web of Science, Scopus, CENTRAL, VHL, and EMBASE. The eligibility criteria of this systematic review used the PICO framework to address the following research question: "In dentate adults requiring an increase in occlusal vertical dimension (OVD) (P), is an evaluation period of the new OVD (I) superior to no evaluation period (C) in terms of success (O)?" Study characteristics, survival, and success rates were extracted from each article.

[Influencing Hard and Soft Tissue Changes Following Tooth Extraction].

Influencing Hard and Soft Tissue Changes Following Tooth Extraction Influencing Hard and Soft Tissue Changes Following Tooth Extraction The loss of a tooth leads to the initiation of resorption processes and thus to the remodeling of the tissues of the alveolar process. At the hard tissue level, this resorption mainly affects the bundle bone at the buccal side of the extracted tooth and occurs most rapidly in the first weeks and months after extraction. Tissue changes occur not only at the level of the hard tissue (bone), but also at the level of the soft tissue.
