Bone augmentation may be sometimes required prior to fixture placement in implant therapy. Bone autograft, allograft or xenograft can be used for augmentation as well as its bone substitute. Many authors recommend to admix platelet-rich plasma (PRP) prepared from various amount of whole patient's blood by centrifugation. As a main reason growth factors stimulating bone regeneration are mentioned which are released from considerable amount of platelets included in PRP. In this review publications were divided into three groups whether authors have evaluated PRP positively or have used PRP without evaluation or have not found benefit.

Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(3): 48-53
The study compares four different procedures of selective preparation of hard dental tissues: ablation by Er:YAG laser radiation (with long and short pulses), preparation by an ultrasound extension with a ball and a classical dental drill. In the long pulses the authors employed interaction energy of 40mJ, duration of the pulse 200 μs and interaction intensity 62kW/cm2; in short pulses the energy was 20mJ, pulse duration 100ns and interaction energy 62kW/cm2. The laser methods were compared with the ultrasound preparation (Sonixflex cariex TV, D - Sonicsys micro) and with the classical preparation. The longitudinal sections...
Dental Materials and Its Prospective Influence on Oral Mucosa
S. Kaprálová, H. Adámková, M. Eber, D. Ditrichová, J. Dobešová
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(3): 54-57
In view of the growing number and technological complexity of new dental materials it has become necessary to evaluate irritation and allergy potential of compound used in dentistry. The authors present a review of possible side effects of dental materials or some of their components.
Clinical Evaluation of Facet Materials in Fixed Prosthodontics (Part.1)
A. Boldaji, E. Cimbura
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(3): 58-60
The aim and purpose of this study was to evaluate the long-term stability of facet crowns, the changes of facet surface, marginal adaptation, cracks or breakage of material, change of shape and colour as well as gingival status and finally the search for the ideal facet restorative material.
The Comparison of Effect of β-tricalciumphosphate and Deproteinized Bovine Bone in Sinus Lift Operation Comparative Histological and Histomorphometrical Study
A. Šimůnek, A. Kohout, D. Kopecká
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(3): 67-71
The aim of this prospective study is to evaluate the quality of ß-tricalciumphosphate (Cerasorb, Curasan Pharma) and deproteinized bovine bone (Bio-Oss, Geistlich) used as augmentation materials for the sinus lift operation.Histomorphometry was carried out from biopsies obtained after nine months of the consolidation of materials. When considering the histomorphometrically assessed volume of the new bone and the residua of foreign material, no statistically significant difference was found between both investigated materials. The addition of a small amount (1:8 to 1:5) of autogenous bone chips harvested from the maxillary tuber did not significantly...
Nanostructured Titan - a New Material for Dental Implants
J. Petruželka, L. Dluhoš, D. Hrušák, J. Sochová
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(3): 72-77
New materials have been developed for dental substitutions, in order to better suit to the demands made from the medical point of view. A prospect material for such purposes is the nanostructured titan (nTi). The paper compares its qualities with those of other materials being used for the same purpose. nTi is, in the same way as the commercially pure titan (cpTi), inert, does not contain any, even only potentially toxic or allergenic ingredients and its specific stability is higher than in any other kinds of materials used for dental implants. nTi has been used to produce screw implants Nanoimplant® of the 2.4mm diameter and the length...
Cognitive-behavioral approach in Psychotherapy of Children with Specific Isolated Phobias (F40.2) - Fear from Stomatological Treatment
Z. Kolařík, K. Nováková, P. Němečková
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(3): 78-83
The aim of the authors was to draw attention to the possibility of treating non-collaborating children, especially if the problem behavior is an isolated phobia from stomatological treatment, using the team collaboration of a stomatologist, psychologist and pediatric psychiatrist. The presented individual psychotherapeutic approach - cognitive behavioral psychotherapy - is more acceptable for the child, safer, more considerate, without side effects, frequently also with a long-lasting effect and less frustrating for the parents. The patients with dental phobia are frequently taken care of in general anesthesia.The stress from stomatological treatment...
Reaction of Dental Pulp after Fracture of a Clinical Crown of Permanent Teeth
H. Hecová, V. Merglová, J. Stehlíková
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(3): 84-87
Fractures of the tooth crown of permanent teeth belong to the most frequent dental injuries. The injury often affects hard dental tissues in complicated fractures, where the fracture line reached into dental pulp, affects dental pulp at well. The aim of this retrospective study was to analyze a group of patients, who were treated for a fracture of dental cap of permanent teeth at the Stomatological Clinic of the Faculty Hospital at Medical Faculty, Charles Unviersity in Plzen (Pilsen). The authors outline possible post-traumatic consequences of this kind of dental injury.
The Knowledge of the First Aid Problems in Tooth Luxation in Primary School Teachers
V. Tzigkounakis, K. Zikmundová, V. Merglová
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(3): 88-92
The aim of the study was to evaluate the knowledge of teachers at Primary Schools in Pilsen about the problem of providing first aid care in most serious injuries of permanent teeth - luxation (avulsion) of the tooth from the alveolus. We elaborated a questionnaire for this investigation consisting of 9 questions and a letter of information about aims of the study. In their answers the teachers could make choice from two of 7 possibilities and mark even more answers. We selected 9 primary schools in Pilsen at random and delivered 300 questionnaires there. Two hundred and twenty three filled-out questionnaires returned (74.3%). Seventy percent of the...
The Use of Occlusion Relaxation Splint during Therapy of Temporomandibular Joint Diseases
V. Machoň
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2006; 106(3): 93-97
The author deals with the evaluation of successfulness in the therapy of dysfunction of temporomendibular joint with the application of occlusion relaxation splint. The described study applied a splint made from a thermoplastic foil by a vacuum technique, treating the lowed dental arch in all cases. The therapy lasted three months.In the evaluation of six months from the beginning of the treatment with the occlusion splint, the therapy was most successful in extracapsular diseases (100%), whereas the works effect was observed in intracapsular diseases (dislocation of the disc with reposition - 31%, disc dislocation without reposition - 55%. It...
