Meanwhile, its effect on the marginal fit and compressive strength of the restoration is not fully understood.
Purpose: This study aimed to evaluate the effect of sintering temperature on the marginal fit and compressive strength of monolithic zirconia crowns.
Objective: The aim of this study was to evaluate the accuracy of shade matching using two spectrophotometric devices.
Materials And Methods: Thirteen patients who require a full coverage restoration for one of their maxillary central incisors were selected while the adjacent central incisor was intact. 3 same frameworks were constructed for each tooth using computer-aided design and computer-aided manufacturing technology.
Background: Socket preservation after tooth extraction is one of the indications of bone grafting to enhance preorthodontic condition. The aim of this study is to determine the effects of socket preservation on the immediate tooth movement, alveolar ridge height preservation and orthodontic root resorption.
Materials And Methods: In a split-mouth technique, twelve sites in three dogs were investigated as an experimental study.
