TRETING THE ALL-ON-4 BRIDGE CARRIER PERIIMPLANTITIS – CASE REPORT

Davor Katanec Robert Ćelić Tomislav Katanec Dragana Gabrić

Koncept imedijatne implanto-protetske rehabilitacije bezube celjusti fiksnim mostom na cetri implantata (All on 4) osmislio je Paulo Malό. Bazira se na ugradnji anguliranih distalnih implantata dužine 15 mm u premolarnoj regiji i dva implantata u interkaninom sektoru koji su imedijatno optereceni fiksnom konstrukcijom. Ovim postupkom osigurava se stabilnost fiksnog nadomjestka bez kirurskih zahvata koji prethode konvencionalnoj implanto-protetskoj terapiji bezube celjusti, kao sto su augmentacija grebena ili podizanje dna maksilarnog sinusa. Mnogi implantoloski sustavi prilagodili su ovaj koncept dizajnu svojih implantata tako da ga susrecemo skoro kod svih implantoloskih sustava. Koncept je zbog jednostavnosti primjene i niže cijene kostanja nasao siroku primjenu u modernoj implantologiji, to je i uzrok sve vece incidencije ranih i kasnih komplikacija koje iziskuju dodatno kirursko ili konzervativno lijecenje. U ovom slucaju pokazati cemo mogucnost uspjesnog lijecenja periimplantitisa anguliranog implantata u regiji 15, distalnom nosa- cu fiksnog mosta na cetiri implantata. Pacijentici staroj 69 god. bez ozbiljnijih sistemskih bolesti, pusac sa pocetnim KOPB-om i progresivnom parodontopatijom u gornjoj celjusti koja je godinama lijecena flap kiretažama, GBR i GTR tehnikama ekstrahirani su preostali zubi i napravljena GTP. Nezadovoljna mobilnim nadomjestkom želi fiksni most. Klinicki i rtg nalaz (CBCT) pokažu reducirani alveolarni grebe s opsežnom pneumatizacijom oba alveolarna recesusa maksilarnog sinusa. Godine 2011. ugrađena su cetiri implantata po sistemu 4 on ICX (angulirani u reg. 15, 25 ᴓ 3, 5/15 i ravni u reg. 13, 23 ᴓ 3, 5/10) na koje je imedijatno postavljen privremeni akrilatni most ojacan metalom. Tri mjeseca nakon ugradnje dijagnosticiran je periimplantitis na anguliranom implantatu reg. 15. Ucini se eksplantacija implantata, odstrani se svo patoloski promjenjeno tkivo te antimikrobna fotodinamska terapija alveole niskoenergetskim laserom (Laser HF, Hager Werken, GmbH). U istom posjetu ucini se augmentacija kostanog defekta ksenogenim kostanim nadomjestkom (Cerabon 05-1mm, Botis dental GmbH, Germany) i ugradnja sireg ICX implantata ᴓ 4, 5/15. Postojeci most imedijatno se fiksira na preostala tri implantata, a ugrađeni implantat prepusti cijeljenju s odgođenim opterecenjem tijekom 8 mjeseci. Nakon razdoblja cijeljenja ucini se kontrolni CBCT koji pokaže urednu oseointegraciju implantata te se privremeni most zamijeni trajnim titan-zirkon mostom. Pracenje tijekom 4 godine pokaže odlicnu oseointegraciju svih implantata, a pacijentica je jako zadovoljna postojecim rjesenjem u estetskom i funkcijskom smislu.

Dentin particulate autograft for alveolar ridge augmentation – a pilot clinical study

Clinical Oral Implants Research (2020)

Luka Marković Igor Smojver Marko Vuletić Tomislav Katanec Ivica Pelivan

Background: A human periodontal ligament fibroblast cell line showed a very promising growth reaction to the mineralized dentin. The mineral and organic matrix compositions of a tooth, dentin, and cementum are almost identical to membranous bone, although, compared to bone, teeth contain more mineral. This feature may be beneficial for volume maintenance since at the remodeling stage dentin graft is resorbed slowly. As a supplement of bone graft material, dentin particulate autograft could be beneficial. Aim/Hypothesis: The aim of this pilot clinical study was to assess efficacy and predictability of dentin particulate autograft as regenerative treatment for alveolar ridge augmentation and two stage implant placement using CBCT radiographic analysis. Materials and Methods: The sample of presented study consisted of 8 patients, with insufficient width of alveolar ridge in lateral lower jaw. After surgical removal of third molar or periodontally compromised tooth, a dentin autograft was prepared according to manufacturer recommendations. Clean extracted teeth were dried and ground in a sterile chamber of the Smart Dentin GrINDIAr® unit (KometaBio Inc., Cresskill, USA). The particulate teeth were immersed in a basic alcohol cleanser to dissolve all organic remnants and bacteria and dehydrated. The particles were rinsed twice with sterile phosphate-buffered saline solution. The platelet-rich fibrin (PRF) membranes were prepared. Graft material was used for ridge augmentation and covered with PRF membranes. After 5 months of healing CBCT scan were made. During implants placement homogeneous integration of dentin particulate was found. Dental implants (BEGO Semados® SC BEGO, Germany) were inserted and restored by titanium abutment and zirconia crown. Results: Clinical re-entry, prior to dental implants placement confirmed a homogeneous integration of dentin autograft and bone-like appearance in former grafted area. Six months after implants placement CBCT scans were obtained as part of the standard procedure. The radiographic images of the target areas revealed no grafted bone resorption around the implants. All patients were followed for 6 months after loading through clinical follow-ups and control CBCT scans. No resorption of the autograft around inserted implants were found. Conclusions and Clinical Implications: Within its limitation, the present pilot clinical study revealed that autologous dentin particulate autograft may serve as an alternative autologous bone substitute to support alveolar ridge augmentation and two-stage implant placement. Keywords: dentin graft, alveolar ridge augmentation, dental implants, bone substitutes, cbct analysis

Dubravka Negovetić Vranić Martina Majstorović Tomislav Katanec

Objective: A combined effect of a new toothpaste containing active ingredients potassium nitrate (5, 00%) and zinc citrate (0, 50%) was tested among a randomly selected group of 80 participants who attended the dental clinic of the School of Dental Medicine in Zagreb (Croatia). Materials and Methods: Participants were aged 16-55 years and equally divided by genders. Inclusion criteria were: hypersensitivity to thermal, chemical and mechanical stimulations due to accumulated plaque and gingival retraction. The toothpaste had previously been clinically tested and had been producedaccording to ISO 9001/14001 integrated quality normatives. Soft toothbrushes were used and provided by the same supplier.Plaque index (Aproximal Silness & Loe Index) and gingival bleeding (Probing Bleeding Index after Saxer & Muhlemann) were clinically evaluated at the initial visit and again at 2 and 4week check-up intervals. Data was analyzed by using analysis of variance (ANOVA), t-test and the Mann-Whitney U test. new toothpaste on reducing gingival bledding and inflammation due to accumulated plaqueand can be recommended in preventing periodontal diseases. Plaque index significantly decreased among participants who used the toothpaste with active ingredients potassium nitrate andzinc citrate (15.4%) vs. participants who used the toothpaste without active ingredients (5.8%). Gingival bleeding significantly reduced among participants who used the toothpaste with active ingredients potassium nitrate and zinc citrate (10.9 %) vs. participants who used the toothpaste without active ingredients (2.5%) .

Maxillary mesiodens in late medieval age archaeological skeletal remains from Rudina, Croatia

Acta stomatologica Naissi (2022)

Luka Banjšak Vlasta Viroubal Tomislav Katanec Ante Miličević

Introduction: The occurrence of mesiodens is somewhat rare, but amongpatients with any kind of supernumerary teeth, it is rather common. From an anthropological point of view, it is interesting to confirm the development of mesiodens in various historical ages. Case report analyses a mesiodens and the surrounding skeletal remains dating from the late medieval ages (13th -16th centuries) which confirms the incidence of the mesiodens and presents the conclusion that historically, mesiodens, as a form of supernumerary teeth has been present throughout history. Conclusion finding of a mesiodens in an archaeological context proves that the occurrence of this type of accessory teeth has been present for at least half a millennium.

Atypical Peripheral Ossifying Fibroma of the Mandible

Dentistry Journal (2022)

Tomislav Katanec Lea Budak Davor Brajdić Dragana Gabrić

Peripheral ossifying fibroma (POF) is a benign localized lesion originating from gingival and alveolar oral mucosa. Its origin can be cells of periodontal ligament. The lesions usually develop in women in their twenties. POF is a complex clinical and histological diagnosis due to its shared characteristics with many other conditions. In this paper, we presented a case of an atypical peripheral ossifying fibroma (POF) in the left lateral part of the mandible in a 70-year-old male patient who had two semicircular bridges supported on four implants in the upper and lower jaws. A review of CBCT and orthopedic imaging showed no visible intraosseous changes. Histological analysis revealed the diagnosis of POF. The case in question is interesting, as elaborated on in the discussion section of this paper because POF is usually found in female patients aged between 20 and 30 years.
