Intrabony periodontal defects are a frequent complication of periodontitis and, if left untreated, may negatively affect long-term tooth prognosis. The optimal outcome of treatment in intrabony defects is considered to be the absence of bleeding on probing, the presence of shallow pockets associated with periodontal regeneration (i.e. formation of new root cementum with functionally orientated ...

Comparative study of two plastic materials, i.e. frozen cortical allobone and demineralized perforated (perfoost) was performed. Testing the samples from same part tibia carried out using Zwick 1464 apparatus. It showed that firmness perfoost lower than allobone: during compression - by 33%, switching 66%, bending 46% for metaphyseal sample 70% diaphyseal one. Perfoost possesses rigidity allows...

Background: Different sources of cultured cells combined with different scaffolds (allogenic, xenogeneic, alloplastic or composite materials) have been tested extensively in vitro and in preclinical animal studies, but there have been only a few clinical trials involving humans. Aim: This study reviewed all of the English language literature published between January 1990 and December 2015 to a...

The importance of operative correction of congenital and acquired defects of the diaphragm has been well demonstrated by the numerous articles published on this subject over the past 30 years. The site and size of the diaphragmatic defect will seldom prevent primary closure; when it does, different methods of plastic repair can be employed (Gross, 1911; Sauerbruch, 1928; Rehn, 1919; Rives and B...

Temporomandibular joint reconstruction (TMJR) is often necessary for patients with severe and/or refractory TMJ disease who have failed conservative treatment. TMJR aids to improve masticatory function and is associated with improved quality of life outcomes. Currently, alloplastic reconstruction is considered as the treatment of choice in most severe TMJ disorders due to its many advantages in...
