Surgery is usually recommended for displaced glenoid fractures, with open reduction and internal fixation as the standard operative treatment. Three approaches have been recommended in the reduction of glenoid fractures: Anterior, posterior and combined; however, a traditional approach may be difficult due to a high position or a comminuted Ideberg type III fracture. The combined approach resul...

BACKGROUND Multiple risk factors have been identified for traumatic dental injuries, including crown fractures, in various age groups and various populations. The objective of this study was to determine the prevalence, risk factors and family related factors for crown trauma among 8 to 16 year-old children in a suburban population, Nigeria. METHODS This is a secondary analysis of a data of 2...

STATEMENT OF PROBLEM Cast posts require sufficient length for prosthesis retention and root strength. For prefabricated metal and fiber posts, the effects of different post lengths on the strength and internal stress of the surrounding root need evaluation. PURPOSE The purpose of this study was to examine, using both experimental and finite element (FE) approaches, the influence of post mater...

No studies are available that evaluate the retention of disilicate crowns according to different cementation procedures. The purpose of this study was to measure the retention of lithium disilicate crowns cemented using two different cementation systems. Twenty extracted mandibular premolars were prepared. Anatomic crowns were waxed and hot pressed using lithium disilicate ceramic. Teeth were d...

Early restoration of the masticatory function, phonatory and aesthetics is some of the current goals of the therapy based on endosseous implants. Facing the classic protocols of implant insertion, which recommend a period of several months between extraction and implant placement, alternatives have been developed that demonstrate that immediate implant placement after tooth extraction permits a...

An abutment for a fixed partial denture may not contain enough tooth structure, such that the abutment does not provide an adequate 'ferrule effect'. A crown or bridge dental prosthesis that is cemented onto such an abutment/s may undergo biomechanical failure. Here, the tooth, core, and post complex, on which the crown is cemented, may fracture off from the abutment, causing the crown to separ...

Simultaneous bilateral posterior dislocation of the shoulder complicated with a fracture (fracture-dislocation) is an extremely rare condition and the relevant literature contains very few published case reports. Besides its rarity, this complicated condition may cause delays in diagnosis because of the physicians’ tendency to use plain radiography which is known to have low sensitivity in dete...
