Background: Implant-prosthodontic rehabilitation improves oral health related quality of life (OHRQoL), but the presence of systemic diseases can also affect the well-being of an individual. The study was carried out to determine the relationship between systemic diseases and OHRQoL after implant-prosthodontic rehabilitation on the basis of psychometric testing by a standardized questionnaire ≫Oral Health Impact Profile« (OHIP). Methods: 130 patients, who received one to eight AnkylosR implants (on average 2.6 } 1.8) were included in this retrospective study in which all aspects of the OHRQoL construct were evaluated with a Slovenian version of the OHIP questionnaire. Data on all present systemic diseases were obtained from the existing health records. Dental status and dental restorations were identified on the basis of orthopantomographic images. Results: The majority of subjects had a cardiovascular disease (N = 37; 28.5 %), followed by a headache (N = 15, 11.5 %), allergies and asthma (n = 13, 10 %), and a rheumatic disease (N = 11, 8.5 %). Only osteoporosis was statistically significantly related to OHRQoL after implant-prosthodontic rehabilitation (p = 0.024). The best multiple linear regression model for the summary score for the questionnaire ≫Oral Health Impact Profile≪ for Slovenia (OHIP), and taking into account gender and age as confounding factors, included the number of remaining teeth and the presence of osteoporosis (p = 0.003, adjusted R2 = 0.104). Conclusions: The total number of remaining teeth in the oral cavity (p = 0.031), the presence of osteoporosis (p = 0.024), and taking into account the subject’s gender and age, are the most important clinical factors that affect the functioning of the SGS as well as psychosocial behavior of the patients after an implant-prosthodontic rehabilitation (adjusted R2 = 0.104). Other systemic diseases (cardiovascular disease, headache, allergies and asthma, rheumatic disease, obesity, gastritis, diabetes, thyroid disease) did not statistically significantly correlate with the OHRQoL concept.

COBISS.SI-ID: 1660844Introduction: Implant-prosthodontic treatment for restoring a single missing tooth, partial edentulism and complete edentulism is a predictive and successful method in terms of both the survival rate of implants and the different parameters which determine the success rate of the treatment. The purpose of this study was to evaluate the 10-year survival and success rates of dental implants, analyze the causes of early and late complications, and assess the type and number of prosthodontic complications. Patients and methods: In 51 patients, 113 titanium dental implants were inserted by one surgeon using a two-stage surgical protocol. The prosthodontic treatment included fixed or removable treatment options. Implant survival and success were evaluated 10 years after the completion of prosthodontic treatment. The evaluation comprised history, clinical examination with assessment of success parameters (prosthesis functionality, peri-implant tissue status), and x-ray assessment of bone loss. Results: Two implants were lost before and two 10 years after the prosthodontic treatment. The survival rate of implants was 96.4 % on the average, 100 % in the lower jaw, and 92.5 % in the upper jaw. Peri-implantitis was diagnosed in 4.5 % of all implants. The success rate was thus 95.5 %. Technical complications occurred in 2.8 % of fixed prostheses and 19 % of removable prostheses. Conclusion: The long-term survival and success rates of dental implants are high. Proper implant prosthodontic treatment planning is crucial to achieving high survival and success rates of implant treatment. Bone quality has to be taken into account when implant treatment is performed. Peri-implantitis is rarely observed, and prosthodontic complications are uncommon. On completion of the surgical and prosthetic phases of treatment, patients must be followed at regular intervals to ensure timely management of complications.

COBISS.SI-ID: 1188012Background: Ectodermal dysplasia (ED) is a group of hereditary diseases with disorders in the development of two or more ectodermal structures, such as hair, teeth, nails and sweat glands. The symptoms of craniofacial anomalies express themselves with a larger number of unerupted teeth - oligodontia. Facial characteristics appear because of disorders in the growth of facial bones due to congenitally missing teeth related to underdeveloped alveolar ridge. Treatment planning in these patients requires interdisciplinary approach, and should include various possibilities of substitution of congenitally absent teeth, orthodontic treatment, orthognatic surgery, skeletal augmentation, surgical insertion of dental implants, prosthetic rehabilitation and genetic counseling. Case presentation: In a patient with ectodermal dysplasia, clinical examination and analysis of panoramic x-ray revealed 17 congenitally absent permanent teeth with extensive atrophy of the alveolar ridge, hypotrichosis, narrow face, prominently expressed chin with speech and mastication difficulties. Rehabilitation planning included an extensive interdisciplinary approach with orthodontically guided three-dimensional correction of the upper and lower jaw relationship that was followed by a surgical open lift of the sinus floor on the right side and insertion of four dental implants. In the mandibular arch, the missing teeth were replaced with a metal-porcelain bridge on the supporting teeth and with two bridges supported on the dental implants in the maxillary arch. After 12 years of interdisciplinary treatment the patient was successfully rehabilitated. Conclusion: Treatment of patients with ectodermal dysplasia andoligodontia is individual and must be targeted mainly at prevention, for itis necessary to conserve the patientʼs own teeth and at the same time replace (the) missing tissues and teeth, and correct the facial structures.

COBISS.SI-ID: 821420Background. The aim of our study was to evaluate the influence of the surgery and radiotherapy of the advanced oral squamous cell carcinoma on the complete blood count, body mass index (BMI), acute inflammatory response, liver enzymes and expression of the CD64 index on leukocytes in the peripheral blood. Patients and method. Venous blood was obtained from 16 patients with advanced oral squamous cell carcinomas treated with radical surgery and external beam radiotherapy. Blood samples were collected prior to surgery (T1), after surgery (T2) and after radiotherapy (T3). Blood samples were analyzed for whole blood count, immunoglobulin G levels, liver enzymes (transaminases (ALT and AST) and gamma-glutamyl trasferase (γ-GT)), inflammatory response markers (C-reactive protein, erythrocyte sedimentation rate, albumin, white blood count, leukocyte count and CD64 expression on leukocytes). Assessment of nutrition was done by calculating the body mass index. Results. Surgery caused anaemia, trombocytosis, leukocytosis, lymphopenia, rise in acute phase proteins, elevation of CD64 expression on monocytes and neutrophyls, elevation of liver transaminases and lowering of γ-GT, albumin, protein and bilirubin levels. After radiotherapy haemoglobin, leukocytes, C-reactive protein, erythrocyte sedimentation rate, liver transferases, albumin, bilirubin and proteins returned almost to T1 levels, levels of lymphocytes, γ-GT and body mass index lowered. IgG levels remained almost unchanged at T2 and T3. Levels of the CD64 expression on monocytes and neutrophyls also elevated after radiotherapy. Conclusions. Surgery caused a significantly larger acute phase response than radiotherapy, while radiotherapy worsened the already present lymphopenia.
