CLASSIFICATIONS OF MANDIBULAR FRACTURES-REVIEW
Hristina Mihailova
Department of Maxillo-facial radiology and oral diagnostic, Faculty of Stomatology,
Medical University - Sofia, Bulgaria
ABSTRACT:
The author makes a brief review of the most familiar classifications of mandibular fractures. It shows that the base of these classifications are the categories connected with anatomical localization of the fractures.
It is point out the necessity of a classification which includes very well defined categories. These categories should be visualized radiologically and should be used easily by doctors with different specialties. The classification of mandibular fractures should be handy for the daily work in Emergency Departments.
Key words: mandibular fracture, classification

CYSTIC LESION OF THE MAXILLA - CASE REPORT
Hristina Mihailova, Br. Kirilov*
Department of Maxillo-facial radiology and oral diagnostic, *Department
of Maxillo-facial surgery, Faculty of Stomatology,
Medical University-Sofia, Bulgaria.
ABSTRACT:
The authors submit a theme concerning a radiolucent lesion of the maxilla. They emphasize on the fact that the clinical and radiological features are difficult to differentiate extensive cyst lesion from those of other odontogenic or non odontogenic benign tumor arising in the upper jaw. The correct diagnose is very difficult and is possible only after histological examination.
They present a case with a large cystic lesion of the maxilla hystologically proved as keratocyst.
Key words: keratocyst, radiolucency, maxilla

SUMMARY:
The use of contemporary composite materials for shaping and restoring of the teeth combined with orthodontic treatment gives great possibilities for dental treatment.
The aim is to present authors’ clinical experience of esthetic reconstruction of distances between the teeth after orthodontic treatment with brackets,
by correcting the form and size of these teeth.
Application of direct composite restorations (light-curing hybrid material
Gradia Direct Anterior, GC) according suitably chosen four clinical cases
after orthodontic treatment, has been demonstrated. Color photos were
taken before and after reconstruction of the tooth form and outlines.
Closing distances between teeth by enlarging tooth size is suitable only
when an esthetic shape and size of the reconstructed teeth is expected.
This way of reconstruction has the following advantages: the esthetic
results are excellent, it preserves the Class I ratio of the canines and
particular height and inclination of the upper incisors in treatment with
premolar extraction only in maxilla and prevents prosthetic treatment
in the anterior teeth.

OUR EXPERIENCE WITH GRADIA DIRECT IN THE RESTORATION OF ANTERIOR TEETH
Snezhanka Topalova-Pirinska, R. Pirinska
Department of conservative dentistry, Faculty of Stomatology,
Medical University, Sofia, Bulgaria
SUMMARY:
One of the greatest challenges in restorative dentistry is creation of well balanced harmony of the natural teeth.
The aim is reconstruction of the integrity and esthetics of the anterior teeth with Gradia Direct Anterior, GS.
Reconstructive treatment of dental erosions, cervical caries and restricted fracture of the incisor edges of permanent anterior teeth was made using composite material Gradia Direct Anterior, GC and multi shade layering technique or just single shade technique. The patients drink Coca-Cola and fruit juices too much. Colour photos before and after restoration were made.
Often the pathological changes in the visible tooth structures cause esthetic, psychological and social discomfort and the appearance of the teeth must be improved. By balanced scientific achievements and improvement of the practical precision the smiles on the face of our patients will be returned.

SUMMARY:
This article describes certain changes that take place during hardening of several kinds of cements and their influence upon vital teeth and the expected reactions of the patients during treatment. It also reveals the probable reason for failure after fixing crowns and bridges. This study shows that unexpectedly “old- fashioned“ cements reveal to certain extent better properties than some of the “up-to-date“ ones.
Key words: vital teeth, crowns and bridges

THE EFFECT OF RELINING ON THE FIT AND STABILITY OF COMPLETE DENTURES -AN IN VITRO AND IN VIVO STUDY
Ilian Hristov, Boyan Pavlov, Daniela Ivanova, Stilian Hristov
Department of Prosthetic Dentistry,
Medical University – Plovdiv, Bulgaria.
SUMMARY:
A technique for estemating in vitro the accuracy of denture bases , using a low-viscosity impression material for determing the space between the die and the dentures upon it was developed.
The measurements showed that relining denture bases with autopolymerizing acrylic resin improved their adaptation to the ridges.
The in vivo study showed no statistically significant change in stability after relining , but the trend was toward increased stability with the relined dentures.
Key words: relining, denture base

Department of Oral Surgery, Faculty of Dentistry,
Medical University – Plovdiv, Bulgaria
ABSTRACT:
The author focuses on the connection between chronic foci of odontogenic origin and their role in the occurrence of non-specific infecto-allergic arthritis, for the time being of uncertain etiology.
It is pointed out that a proper radical treatment of stomatogenic foci is required, so that recurrence of arthritic diseases can be avoided.
Key words: stomatogenic foci, diseases of the joints

Hrizdana Hadjieva, Mariana Dimova, S. Todorov
Department of Prosthetic Dentistry, Faculty of Stomatology,
Medical University - Sofia, Bulgaria.
ABSTRACT:
Introduction.The prosthetic stomatitis is a multietiological condition. The clinical manifestation could be the same nevertheless what is the etiology and at the same time one and the same reason could result in different clinical manifestation.
The purpose of this investigation is to establish the frequency of denture stomatitis, its etiology, diagnosis and treatment.
Materials and methods. The authors have investigated 300 patients with removable complete and partial dentures. The patients with denture stomatitis were 54. All of these 54 patients were subjected to microbiologic tests and tests for allergy to pink and clear polymethylmethacrylate. The quality of the prosthetic treatment was checked: the extension of the borders, the vertical occlusal distance, the occlusion and the dentures’ fir to the underlying mucosa.
Results: From all 300 patients 54 (18%) were diagnosed with prosthetic stomatitis. By 18 patients (6%) we established oral candidosis, and by 12 patients( 4%) we observed positive allergic tests. By 18 patients( 6%) the reason for the inflammation was due to trauma from the prostheses. By 27 patients(9%) the denture and oral hygiene were unsatisfactory.
Summary: Denture stomatitis is not a rare condition. Its treatment will be successful if only the etiologic factor or factors are established.
Key words: denture stomatitis, allergic stomatitis, trauma from dentures, Candida associated denture stomatitis

TOTAL PROSTHETICS IN FUNCTION
Mariana Dimova, Hrizdana Hadjieva
Department of Prosthetic Dentistry, Faculty of Stomatology,
Medical University - Sofia, Bulgaria
ABSTRACT:
Introduction. Biologic, physioliogic and mechanical principles need to be considered and carefully coordinated in the establishment of the total denture design and occlusion.
The aim of the authors is to share their experience with total denture treatment by patients, edentulous more than 6 years, using the method of intraoral registration of the position of the lower jaw by Gerber and arranging the artificial teeth by Korholz.
Material and methods. Fourteen patients, six men and eight women, mean age 61 years, edentulous more than 6 years were treated. After all the requirements of a functional impressions and determining of the vertical jaw relation are kept, the central position of the lower jaw was fixed by intraoral registration by Gerber, using the face bow "Kavo" and transferring plates. The models were mounted into an articulator "Protar" IV and the artificial teeth (Ivoclar-ortotype) were arranged by the method of Korholz.
Results and discussion. The patients were asked about their experience and comfort with the new dentures and subjective tests for estimation of dentures' stability were applied. The quick and full adaptation to the dentures and the scarce need of corrections allow us to recommend this method of treatment by patients, edentulous from seven years and with advanced atrophy of the jaws.
Conclusions: Using the intraoral graphic registration of the central position is a substantial step towards denture accuracy and stability. The arrangement of the teeth by Körholz is a prime factor to this goal.

CHANGES IN CORRELATIONS BETWEEN CERVICAL CROWN EDGE AND MARGINAL GINGIVA IN FIXED PROSTHODONTICS
Mariana Dimova, Velichka Doseva
Department of Prosthetic Dentistry and Department of Periodontology, Faculty of Stomatology,
Medical University - Sofia, Bulgaria.
ABSTRACT:
Gingival adaptation of fixed prosthodontics and periodontal tissue’s assessment place the main role in prosthodontics long term results.
The aim of this study was to assess changes in correlations between cervical crown edge and marginal gingiva in patiens with fixed prosthodontics.
Material and methods: 54 patients: 31 women and 23 men, aged from 32 to 71 years (middle age- 52 years) were examined. Patients were with different fixed constructions: full metal, metal-ceramic, acrylic and PFM crowns and bridges with 2 to 25 years longevity (middle duration of presence- 14 years).
Clinical periodontal examinations included: hygiene index, gingival bleeding (PBI), the distance between cervical crown edge and marginal gingiva, probing pocket depth, clinical attachment level, gingival overgrowth, tooth mobility.
Results: Clinical examination indicated little inflammation of the gingival tissues of crowned teeth with margins at the gingival and minor clinical signs of inflammation in cases with supragingivally location of the crown margin. Higher average of PBI was observed when the crown margins were located subgingivally. In summary- crowns and fixed prosthodontics increased the incidence of advanced gingival inflammation adjacent to restorations, particularly if they had intracrevicular finish line placement, poor marginal adaptation, and rough surfaces.
Conclusion: The main factors to realize periodontal prophylactic role of fixed prostodontics and to preserve periodontal health are exact adaptation of crowns and retainers toward gingival preparation limits, maximum release of the interdental spaces, correct contour of the crowns, good polishing, motivation and instruction for mouth hygiene of the patient.
