Sound preparation design enhances longevity for majority of the restorations. Dentistry has come a long way from an empirical art to a well-developed sophisticated science with a background. This has been made possible with the understanding of biomechanical principles. A prosthesis is a mechanical device which has to be accommodated harmoniously in a biological environment i.e. the oral cavity and the associated structures of the stomatognathic system. A thorough understanding of the biomechanical principles facilitates any treatment. This text is an effort to uplift the scientific basis for...

Self Compacting Concrete(SCC), one of the latest innovations in concrete technology, offers a number of benefits over Normally Vibrated Concrete(NVC). Because of its inherent advantages, SCC is gradually replacing most of the NVC currently produced and generated tremendous interest amongst the researchers, engineers and concrete technologists. The title presents an investigation conducted to study the flexural fatigue characteristics of Self Compacting Concrete (SCC) and Steel Fibre Reinforced Self Compacting Concrete (SFRSCC).An extensive experimental programme was planned to obtain flexural...

Dental implants are valuable devices for restoring lost teeth.Implants are available in man shapes, sizes and lengths using a variety of materials with different surface properties.Among the most desired characteristics of an implant are those that ensure that the tissue-implant interface will be established quickly and then will be firmly maintained.It is especially difficult to assess whether the various modifications in the latest implants deliver improved performance.Thus far, metanalysis of randomized clinical trials finds no evidence of any particular type of implant having better...

Sleep apnea is one of the common upper respiratory disease.It is of 3 types- central, mixed, obstructive. The main symptoms are tiredness, lack of concentration, anxiety, snoring etc which can further lead to following consequences; road traffic accidents, hypertension, cardiovascular diseases and death.Diagnosis can be done by both general practitioner as well as dentist.The treatment modality include change in life style, oxygen and drug therapy, mechanical ventilation by Continuous positive airway pressure therapy Surgeries like hyoid suspension surgery and dental management by appliances...
