Cílem článku je podělit se o naše zkušenosti se zhotovováním 3D modelů autotransplantovaných zubů a jejich vlastním použitím při výkonu. Zhotovení 3D repliky zubu pro chirurgické využití má tři fáze: tvorba virtuálního modelu repliky, výroba pomocí 3D tiskárny a sterilizace. Na naše oddělení byla doporučena 37letá zdravá pacientka k návrhu řešení stavu zubů ve II. kvadrantu. Po posouzení klinického stavu, zhodnocení CBCT (cone beam computed tomography) a po domluvě s pacientkou jsme se rozhodli pro extrakce zubů 26, 27 a následně autotransplantaci zubu 28 do místa 26. Na základě dat z CBCT jsme vytvořili dva 3D modely autotransplantovaného zubu a provedli jejich sterilizaci. Po extrakci zubů 26 a 27 jsme extrakční ránu 26 upravili za pomoci vytvořených 3D modelů a provedli autotransplantaci, přičemž extraalveorální čas zubu 28 byl pouze 21 vteřin. Hojení proběhlo bez komplikací a pacientka je s výsledkem spokojená. Autotransplantace je jednou z možností volby při řešení ageneze nebo ztráty zubu. Využití 3D modelu při operačním zákroku vede k výraznému zkrácení extraalveolárního času autotransplantátu a ke snížení nebezpečí poškození buněk periodontálního ligamenta opakovaným vkládáním autotransplantátu do připravované štoly.
The aim of this study is to show the experience with autotransplanted 3D model development and its use during surgery. The development of a 3D model has undergone three phases: building the virtual model, 3D printing and finally sterilisation. A 37-year-old female patient was recommended to our department for treatment of the 2nd quadrant. After planning the extraction of 26, 27 and consequently autotransplantation of tooth 28 was decided. According to CBCT data, two 3D models of the autotransplanted tooth were built and plasma sterilisation was done. After extraction of 26 and 27, a tooth cavity was prepared for the 3D model phantom and the autotransplantation was finished; extra alveolar time of tooth 28 was only 21 seconds. Healing period had no adverse problems and the patient was very satisfied with the result. Autotransplantation is one of the possible choices when treating malformation or tooth loss. The use of a 3D phantom during surgery leads to shortening of surgery time, thus lowering the risk of periodontal tissue damage by repeated testing of the right size of the tooth position and size.

Na pracovišti ambulance bolesti v Českých Budějovicích se v posledních dvou letech věnujeme ošetřování akutní progrese chronických bolestí hlavy intranazální aplikací lidokainu. Jedná se o ambulantní, minimálně invazivní a pacienty dobře snášenou metodu. V poloze vleže podáváme malé množství 4% lidokainového gelu opakovaně po 3–5 minutách celkem 3–5krát nosní dírkou na postižené bolestivé polovině hlavy. Aplikátor zavádíme po znecitlivění vstupu do nosu šetrně až do kontaktu se zadní stěnou nosohltanu, pod jehož sliznicí se nachází trigeminální ganglion. Cílem ošetření je ovlivnit lokálním anestetikem ganglion sphenopalatinum a snížit vedení bolesti v povodí trigeminálního nervu z postižené poloviny hlavy a obličeje. Zákrok provádíme opakovaně třikrát týdně. Výkon často kombinujeme s podáním antineuropatické infuze. Metodu jsme vyzkoušeli u pacientů s postherpetickými bolestmi obličeje, při atakách bolestí hlavy u pacientů s roztroušenou sklerózou, u pacientů čekajících na intervenční zákrok při neuralgiích trigeminu na podkladě neurovaskulárního konfliktu. Dobrý efekt byl pozorován i u akutních postpunkčních bolestí hlavy a u migrény. Úlevu od bolesti lze pozorovat po 1–2 hodinách a trvání efektu léčby je velmi individuální: 2 dny až 4 týdny. Opakování zákroku obden a současná aplikace antineuropatické infuze nebo myorelaxační infuze potencují analgetický účinek. Ošetření bývá pacienty dobře snášeno. Při zavádění aplikátoru může dojít k poranění nosní sliznice, během aplikace je patrné slzení, necitlivost a pocit chladu pod okem a v okolí jařmového oblouku ošetřované strany. Občas se vyskytne pálení v oblasti nosohltanu ze zatékajícího lidokainového gelu, což se dá ovlivnit množstvím aplikované látky. Ze zájmu pacientů o opakování aplikace lze usuzovat na pozitivní efekt metody.
At the pain clinic in Budweis, we have been treating the acute progression of chronic headaches using intranasal lidocaine for the past two years. It is an outpatient, minimally invasive method that is well tolerated by patients. In the supine position, we administer a small amount of 4 % lidocaine gel repeatedly after 3-5 minutes a total of 3-5 times through the nostril on the affected painful half of the head. After anesthetizing the entrance to the nose, the applicator is gently inserted until it comes into contact with the back wall of the nasopharynx, under the mucosa of which the trigeminal ganglion is located. The aim of the treatment is to affect the sphenopalatine ganglion with a local anesthetic and to reduce the conduction of pain in the basin of the trigeminal nerve from the affected half of the head and face. We perform the procedure repeatedly 3 times a week. We often combine the procedure with the administration of an antineuropathic infusion. We tried the method in patients with post-herpetic facial pain, in headache attacks in patients with multiple sclerosis, in patients waiting for intervention for trigeminal neuralgia based on neurovascular conflict. A good effect was also observed in acute postpuncture headaches and migraines. The effect can be observed after 1-2 hours and the duration is very individual from 2 days to 4 weeks. Repeating the procedure every other day and simultaneous application of antineuropathic infusion or myorelaxant infusion potentiate the analgesic effect. Treatment is usually well tolerated by patients. When inserting the applicator, the nasal mucosa may be injured, during the application there is steamy lacrimation, numbness and a feeling of coldness under the eye and around the zygomatic arch of the treated side. Sometimes there is a burning sensation in the nasopharynx area from leaking lidocaine gel, which can be influenced by the amount of applied substance. The positive effect of the method can be inferred from the patients‘ interest in repeating the application.

BACKGROUND: This 20-year retrospective study aimed to evaluate the treatment methods used in patients with impacted maxillary permanent canines and to determine the occurrence of ankylotic and resorptive processes and their association with potential risk factors. METHODS: The cohort consisted of 351 consecutive Caucasian patients (120 males and 231 females, mean age 18.4 and 19.9 years, respectively) with 420 impacted maxillary permanent canines. CT and CBCT findings were subsequently confirmed during surgery. Statistical analyses were performed by the generalized linear models, Pearson x2 and Fisher exact tests using the statistical programs R and Statistica v. 14. RESULTS: A total of 273 (65.0%) impacted canines were aligned in the dental arch by orthodontic traction after surgical exposure, this treatment was predominant in patients under 20 years of age. Surgical extraction was performed in 115 (27.2%) impacted canines and was more common in older patients. Ankylotic changes were recorded in 61 (14.5%) impacted canines. The probability of ankylosis increased with age, particularly after the patient's 20th year of life (p < 0.001). Patients were 1.2% likely to develop ankylosis at age 15 years, 4.3% at age 20 years, 14.1% at age 25 years, and 96.8% at age 45 years. Invasive cervical root resorption (ICRR) was found in 8 (1.9%) canines. In 4 canines (1.0%), root ankylosis in addition to ICRR was observed. In contrast to ankylosis, whose frequency of occurrence increased with age, the occurrence of ICRR resulting from PDL damage during surgery was more typical in younger patients. Canines in a high position above the root apices of the adjacent teeth, with a horizontal inclination of the longitudinal axis, with the crown located deep in the center of the alveolar bone and with labiopalatal position, should be considered critically impacted canines with a high risk to failure of orthodontic traction. CONCLUSION: In conclusion, the treatment of impacted canines depends mainly on the age of the patient, and the position and inclination of the longitudinal axis of the impacted tooth. To select an adequate treatment method, we recommend CBCT examination, which allows a precise analysis of the position of impacted canines.

AIM: The objective of this paper is to describe and discuss the most commonly occurring limits in care provision between a dentist and a child, i.e. provider and recipient. METHODS: The study was conducted online in the form of an anonymous questionnaire survey. We were looking for dentists to answer two basic modeled situations during the treatment of deciduous teeth (filling and extraction) in 4-year-old and 8-year-old children. Each modeled situation had 9 possible clinical scenarios. The age was chosen to factor the cooperation of a preschool- and a school-age child. CONCLUSION: The experience gained through clinical practice and the number of treated children show to be fundamental for the treatment of child's deciduous teeth and for the selection of a treatment method. Dentists acquire sufficient knowledge through their education in the faculties of medicine. The limit is the child itself, therefore it is desirable to build specialised centres for their treatment.
INTRODUCTION: Risk factors for developing osteoradionecrosis (ORN) are well known, but less is known about factors influencing the interval between radiotherapy and the onset of ORN. Also, it is unknown whether there is any specific period post-radiotherapy with a reduced probability of ORN when irradiated teeth require extraction. PURPOSE: The primary aim of this study was to identify factors influencing the interval in developing ORN in the following subgroups of patients: (1) patients who spontaneously developed ORN, (2) surgical-intervention-related ORN with a particular focus on patients after mandibulectomy. The secondary aim was to attempt to identify a possible time for safer dental intervention after primary treatment. MATERIALS AND METHODS: The authors retrospectively analysed 1608 head and neck cancer (HNC) patients treated in a single centre. Time intervals were measured from the end of radiotherapy to the development of ORN and further analysed in the subgroups listed above. RESULTS: In all, 141 patients (8.8%) developed intra-oral ORN. Median time from radiotherapy to ORN development in the whole cohort was 9 months. Median interval for spontaneous ORN was 8 months, 6.5 months for intervention-related ORN, and 15 months for patients post-mandibulectomy. In patients who required dental extraction preradiotherapy, median interval of ORN onset was 5 months. CONCLUSION: In our study, a slightly higher proportion of patients with intervention developed ORN earlier in comparison with spontaneous ORN. The period from 12-18 months after radiotherapy was identified as having the highest probability of developing ORN in patients after mandibulectomy. A time for safer dental intervention after primary treatment was not identified.

Úvod a cíl: Předkládaná kazuistika dokumentuje průběh diagnostiky a léčby neoplazie plazmatických buněk dolní čelisti 79leté pacientky. Cílem je upozornit na možnost manifestace plazmocytomů v diferenciální diagnostice lézí čelistních kostí a zároveň zdůraznit důležitost mezioborové spolupráce, v tomto případě dentoalveolárního/maxilofaciálního chirurga a hematoonkologa. Popis případu: Pacientka byla na našem pracovišti poprvé vyšetřena v listopadu 2023 na žádost praktického zubního lékaře z důvodu opakujících se obtíží po extrakci stálého dolního druhého moláru vpravo (zub č. 47), která byla provedena o dva měsíce dříve. Pacientka byla v roce 2021 operována pro karcinom vaječníků, netrpěla diabetem, krvácivými projevy, dušností ani jinými chorobami. Neužívala léky ovlivňující kostní metabolismus. Na základě klinického obrazu, délky trvání příznaků, OPG zobrazujícího neostře ohraničené projasnění těla mandibuly v oblasti chybějících zubů a laboratorního vyšetření byla stanovena pracovní diagnóza osteomyelitida těla dolní čelisti vpravo. Neprodleně byla zahájena empirická léčba perorálními širokospektrými antibiotiky penicilinové řady, která přinesla klinické zlepšení. CBCT zhotovené dva dny po prvním vyšetření odhalilo nejasně ohraničené osteolytické ložisko způsobující resorpci lingvální stěny těla mandibuly dosahující spodní hrany dolní čelisti v oblasti molárů vpravo dole. Tento rentgenologický nález vedl k podezření na zhoubný novotvar dolní čelisti. Následné vyšetření pomocí CT s kontrastní látkou potvrdilo infiltraci měkkých tkání a výše popsaný charakter osteolytické léze. Na základě těchto nálezů byla indikována a provedena diagnostická biopsie části patologické tkáně, která odhalila plazmocytární neoplazii. V diferenciální diagnostice bylo nutné rozlišit, zda se jedná o solitární kostní plazmocytom s extraoseální propagací, nebo infiltraci mnohočetným myelomem. Pacientka byla odeslána na hematologické vyšetření na specializované pracoviště, kde byla definitivně stanovena diagnóza mnohočetného myelomu. Zde byla pacientka léčena trojkombinací bortezomidu, lenalidomidu a dexametazonu. Již první cyklus této léčby vedl k úplné regresi intraorální léze a zhojení extrakční rány v místě zubu 47. Závěr: Tato kazuistika upozorňuje na méně častý, avšak možný výskyt plazmocytomů v dutině ústní a zdůrazňuje důležitost mezioborové spolupráce.
Introduction and aim: The presented case study documents the course of diagnosis and treatment of plasma cell neoplasia of the lower jaw in a 79-years-old female patient. The aim is to highlight the possibility of plasmacytoma manifestation in the differential diagnosis of jawbone lesions and to emphasize the importance of interdisciplinary cooperation, in this case between the dentoalveolar/maxillofacial surgeon and the haematooncologist. Case description: The patient was first examined at our facility in November 2023 upon the request of a general dental practitioner due to recurrent difficulties following extraction of the right permanent lower second molar (tooth #47), which had been performed two months earlier. In 2021, the patient underwent surgery for ovarian carcinoma and had no history of diabetes, bleeding disorders, shortness of breath, or other illnesses. She was not using any medications affecting bone metabolism. Based on the clinical findings, duration of symptoms, OPG image showing noticeable poorly defined radiolucency of the mandibular body in the area of missing teeth, and laboratory tests, a working diagnosis of osteomyelitis of the mandibular body on the right side was established. Empirical treatment with oral broad-spectrum antibiotics of the penicillin class was initiated promptly and resulted in clinical improvement. Cone-beam computed tomography (CBCT) performed two days after the initial examination revealed osteolytic indistinctly demarcated changes causing lingual wall resorption of the mandibular body reaching to the lower edge of the mandible in the region of the molars on the lower right side. This radiological finding raised suspicion of malignant neoplasm of the lower jaw. Subsequent CT scan with contrast confirmed soft tissue infiltration and the osteolytic nature of the lesion described above. Based on these findings, a diagnostic biopsy of the pathological tissue was indicated and performed, revealing plasma cell neoplasia. In the differential diagnosis, it was necessary to distinguish whether it was a solitary bone plasmacytoma with extraosseous propagation or multiple myeloma infiltration. The patient was referred for haematological examination to a specialized clinic where a definitive diagnosis of multiple myeloma was established. There the patient was treated with a triple combination of bortezomide, lenalidomide, and dexamethasone. The first cycle of this treatment resulted in complete regression of the intraoral lesion and healing of the extraction socket at the site of tooth #47. Conclusion: This case study highlights the rare but possible occurrence of oral plasmacytomas and emphasizes the importance of interdisciplinary collaboration.

BACKGROUND: Previous studies have assessed different aspects concerning the applications of i-PRF in the oral cavity. However, nothing is known regarding patients' perceptions of the injection of autologous platelet-rich fibrin (i-PRF). OBJECTIVES: To investigate patients' perceptions after injecting platelet-rich fibrin (i-PRF) in the course of retracting upper canines. METHODS: Twenty-one patients, whose treatments required extractions of both upper first premolars, were recruited. Extraction side was randomly allocated to the intervention or control sides. After the alignment phase, i-PRF was injected twice with a one-month interval on the buccal and palatal aspects of the extraction sites (intervention side). Patients' perceptions were evaluated with two questionnaires: the first was used to assess the level of pain, discomfort, swelling, eating and swallowing difficulties as well as jaw movement restriction after 1 h (T1), 2 h (T2), 6 h (T3), 24 h (T4) and 48 h (T5) of the second injection; the second questionnaire was used to assess the acceptance of the i-PRF injection and overall satisfaction with this technique at the end of canine retraction phase. Visual Analogue Scale (VAS) was adopted for this purpose. Wilcoxon Signed Rank Test was used to compare between both sides at all time points while Friedman's Test was the selected test for detecting variables' changes over time. Post-hoc Wilcoxon Matched-Pairs Signed-Rank Tests were applied when any of the results were significant. As to the multiplicity of tests, Bonferroni Correction was implemented. RESULTS: Pain and swelling levels were significantly higher on the experimental compared to the control sides at T1, T2, and T3 (P < 0.05), whereas they declined sharply and went back to almost normal values at T4 (after 24 h). At T5 they were 0. Discomfort and difficulty in mastication on intervention sides were significant only at T1 and T2. Pain, swelling, and chewing difficulties were significant (P < 0.001) during the 4 assessed time points. The increase was insignificant regarding swallowing difficulties and jaw movement limitations at all time intervals. CONCLUSIONS: Injecting autologous (i-PRF) during orthodontic canine retraction is a well-perceived and well-tolerated method due to the limited discomfort which significantly diminishes 24 h afterwards.
