Awake Bruxism-Single-Point Self-Report versus Ecological Momentary Assessment.

J Clin Med 2021 Apr 15;10(8). Epub 2021 Apr 15.

Department of Oral Rehabilitation, The Maurice and Gabriella School of Dental Medicine, Tel Aviv University, Tel Aviv 6139001, Israel.

Assessment of awake bruxism (AB) is problematic due to the inability to use continuous recordings during daytime activities. Recently, a new semi-instrumental approach was suggested, namely, ecological momentary assessment (EMA), via the use of a smartphone application. With the application, subjects are requested to report, at least 12 times per day, the status of their masticatory muscle activity (relaxed muscles, muscle bracing without tooth contact, teeth contact, teeth clenching, or teeth grinding).

Ji-Young Song

J Korean Assoc Oral Maxillofac Surg 2021 Apr;47(2):149-150

Department of Dentistry, School of Medicine, Jeju National University, Jeju, Korea.

Bruxism is defined as a parafunctional activity during sleep or while awake that includes locking and grinding of teeth and clenching. It generates excessive occlusal force that may lead to implant failure. Therefore, diagnosis of bruxism and providing specific protocols such as occlusal splint and/or injection of botulinum toxin before implant installation are important to prevent increases the risk of implant failure in bruxism patients.

Short-term effects of NTI-tss and Michigan splint on nocturnal jaw muscle activity: A pilot study.

Clin Exp Dent Res 2020 Dec 25. Epub 2020 Dec 25.

Clinic of Masticatory Disorders, Center of Dental Medicine, University of Zurich, Zurich, Switzerland.

Objectives: Sleep bruxism is mostly assessed by reporting of tooth-grinding or clenching during sleep and by clinical signs (tooth wear, cracks, or fractures). Parafunctional tooth damage is usually prevented by employing occlusal appliances mainly of the full arch covering type (Michigan splint) and of the partial type covering only central incisors (NTI-tss). To date, the effects of occlusal appliances on sleep bruxism or jaw muscle activity during sleep are still controversial. Read More

Influence of CAD/CAM milling, sintering and surface treatments on the fatigue behavior of lithium disilicate glass ceramic.

J Mech Behav Biomed Mater 2021 01 7;113:104133. Epub 2020 Oct 7.

School of Mechanical Engineering, The University of Adelaide, Adelaide, SA, 5005, Australia. Electronic address:

This paper reports on the process-fatigue relation of lithium disilicate glass ceramic (LDGC) using low-cycle, high-load Hertzian indentations with a rigid indenter to simulate teeth grinding/clenching of LDGC restorations with different surface asperities obtained in CAD/CAM milling, sintering, polishing and glazing. The maximum contact stresses were evaluated as functions of the number of load cycles and surface treatments using the Hertzian model. Indentation-induced surface damage was viewed using scanning electron microscopy (SEM) to understand the relationships among microstructures, surface asperities, crack morphology and propagation.

In silico study of cuspid' periodontal ligament damage under parafunctional and traumatic conditions of whole-mouth occlusions. A patient-specific evaluation.

Comput Methods Programs Biomed 2020 Feb 4;184:105107. Epub 2019 Oct 4.

Group of Biomaterials, Aragon Institute of Engineering Research (I3A), University of Zaragoza, Zaragoza, Spain.

Background And Objective: Although traumatic loading has been associated with periodontal ligament (PDL) damage and therefore with several oral disorders, the damage phenomena and the traumatic loads involved are still unclear. The complex composition and extremely thin size of the PDL make experimentation difficult, requiring computational studies that consider the macroscopic loading conditions, the microscopic composition and fine detailed geometry of the tissue. In this study, a new methodology to analyse the damage phenomena in the collagen network and the extracellular matrix of the PDL caused by parafunctional and traumatic occlusal forces was proposed.
