The effect of biologically oriented and subgingival horizontal preparation techniques on periodontal health: A double-blind randomized controlled clinical trial

“…In contrast, the Biologically Oriented Preparation Technique (BOPT), introduced by Loi and Di Felice (2013) , is considered less invasive, more aesthetic, and promotes a stable soft tissue profile near the prosthesis/tissue interface. Several studies support the influence of SHPT on periodontal health, while the vertical BOPT technique is considered more conservative and facilitates impression-taking due to its finish area rather than a defined finishing line, which improves marginal fit ( Patroni et al, 2010 , Poggio et al, 2012 , Schmitz et al, 2017 ). However, there is a lack of sufficient scientific evidence to fully support the BOPT technique, highlighting the need for longitudinal clinical trials ( Patroni et al, 2010 , Poggio et al, 2012 , Schmitz et al, 2017 ).…”

To address this gap, a prospective randomized clinical trial was conducted at the Qassim Regional Dental Centre to investigate the influence of SHPT and BOPT techniques.…”

Effect of Pre-Crystallization on Lithium Disilicate Glass-Ceramics Fabricated by Different Processes

“…Due to the increasing demand for more aesthetic appearances, all-ceramic restorations have become very popular over the last decade because they can fulfill biomechanical requirements and the enhanced esthetics demand [1][2][3][4][5] . One all-ceramic system is lithium disilicate glass ceramic (Li 2 Si 2 O 5 ), currently used for dental restorations for mainly dental crowns, bridges and veneers because of its excellent mechanical properties, longevity and esthetic characteristics [4][5][6][7][8][9][10][11] .…”

Lithium disilicate glass ceramic has superior optical properties by itself.…”

“…Two main technologies extensively used to fabricate lithium disilicate glass ceramic were a computer-aided design/computer-aided manufacturing (CAD/CAM) technology and a hot pressing process. The CAD/CAM technology is quite practical for producing customized dental applications for patients from simply shaped blocks of materials 4,15 . The CAD/CAM restorations are better-fitting, more durable and more natural looking (multi-colored and translucent, similar to natural teeth) than previously machined restorations.…”
