  • Purpose: The aim of this study is to evaluate the flexural strength of flexible resins and the flexibility of different resin splint (RS) systems in comparison with resin wire splint (RWS) system. Materials and methods: Three different resin materials (G-aenial flo, GA, GC; Superbond, SB, Sun medical; G-fix, GF, GC) were tested flexural strength test in accordance with ISO-4049:2000. For the flexibility test of splint systems, a artificial model with resin teeth was used to evaluate three types of resin splint systems (GA, SB, and GF) and one resin wire splint system. The left central incisor was simulated 'injured teeth' with third degree mobility. Three consecutively repeated measurements of periotest value were taken in horizontal direction, before and after splinting to access tooth mobility. The splinting effect was calculated through the periotest value. Differences were evaluated through One-way Anova and Tukey HDS post-hoc tests for pair-wise comparison (${\alpha}=.05$). Results: Although GA group showed significant higher flexural strength than SB and GF groups, all of three different resin splint systems produced a significantly higher and rigid splinting effect compared with 016" resin-wire splint system (P < .05). Conclusion: Within the limits of an in vitro study, it can be stated that resin splint systems are too rigid and may not be acceptable to treat tooth avulsion.

  • Traumatic injuries to the primary dentition are commonly encountered problems in dental practice. It is found that 30% of the children had injuries to the primary dentition and 22% to the permanent dentition. The greatest incidence of trauma to the primary dentition occurs at the ages of 2 and 3 as children start to learn motor coordination. Because teeth and alveolar bone are traumatized simultaneously, alveolar bone fractures are likely to occur when multiple teeth are involved in injuries. Dental splints are indicated for the management of maxillofacial fractures. They enable anatomic reduction of fractured segments and help immobilization and maintenance of the fragments after reduction. They also act as a stabilizer during rehabilitation. Various types of dental splints are available. In this case, routine resin-wire splint technique could not be applied because of the child's uncooperative behavior. Oral sedation was not indicated because N.P.O. had not been preceded. Therefore, we decided to use open-cap acrylic splint instead. Stabilization using open cap acrylic splint requires minimum chair time with reduced discomfort to both patient and dentist. It is an effective means of splint for uncooperative children and especially useful when other means of fixation have been failed. Because trauma on the primary dentition can affect the underlying permanent tooth germ, it is important to monitor eruption process of the permanent dentition.

  • Reposition and splinting has been widely recommended when clinicians treat traumatically dislocated tooth. This case represents stabilization of traumatized tooth in a cerebral palsy patient who failed resin wire splint because of parafunctional oral habit and lack of cooperation. Clinically, mobility of traumatized tooth decreased due to stabilization using vacuum-formed splint with posterior occlusal block in 2 weeks. Vacuum-formed splint may be a simple and effective stabilization technique for traumatized tooth in a cerebral palsy patient.

  • One of the many dilemmas that the clinical restorative dentist must face is treating young adolescent patient who prematurely loses his permanent teeth. Temporary prosthetic replacement can be achieved with removable denture, orthodontic band-wire fixed denture, adhesion bridge, composite resin splint with reinforcing material until the patients go through growth and development. But, all of these have limitations. Advances in restorative materials and reinforcement materials have made possible new techniques which are as much esthetic, conservative and more economic and stronger than adhesion brides. Two cases are being presented where gas-plasma treated, woven polyethylene fabric to reinforce composite resin was used to fabricate a temporary prosthetic restoration to replace a missing maxillary central incisor. This relatively noninvasive and basically reversible procedure allows the patient to decide the final restoration as he or she goes thorough maturation of the hard and soft tissues.

  • A five-month-old toy poodle was referred for treatment of bilateral mandibular fractures. Preoperative skull and dental radiographs showed rostral mandibular fractures and permanent teeth that had not yet erupted. In addition to providing stability for the healing of fractures, it is very important to focus on restoring normal occlusion. The mandibular fractures were repaired using interdental wiring in a dentate area where the deciduous canines and fourth premolars were stable and could be used to anchor the interdental fixation. In the absence of an erupted permanent mandibular first molar, the modified Risdon wiring was performed using the deciduous mandibular fourth premolars as anchor teeth. An intraoral splint was placed on the mandibular teeth using self-curing composite resin. Five months after surgery, the patient had experienced no complications, and the permanent teeth had erupted normally. In this case, which involves a small-breed puppy with deciduous dentition, treatment with a wire-reinforced interdental splint using intact deciduous fourth premolar teeth as anchor teeth can be considered as a suitable method for rostral mandibular fracture restoration.

  • Neuroblastoma is a common malignant tumor of the sympathetic nervous system in childhood, arises from embryonic neural crest cells. The period of tooth development is matched with peak times of diagnosis and treatment of neuroblastoma. The intensive multimodality treatment including radiotherapy and chemotherapy is used in patients with neuroblastoma has been shown to have late adverse effects and disturbances in dental development like tooth agenesis, microdontia, enamel hypoplasia and short roots. A 8-year old girl had been on medication and radiotherapy for neuroblastoma since she was 15 months old at Department Pediatrics, Chonnam National University Hospital. Oligodontia, microdontia, and short root formation was notable in clinical and radiological examination. Mobility of lower permanent incisor was detected and measured at about degree 2. Resin wire splint using mini-screw implantation on buccal alveolar bone was conducted for maintenance of mandibular incisors and alveolar bone. Excessive mobility has been eliminated and maintained well so far. Further treatment is planned for re-evaluation of mobility, preventing dental caries and regular oral hygiene management. Although we need further evaluation, this treatment could be one of alternative therapy for those who have similar dental anomalies.

  • Patients with cerebral palsy have higher risk of traumatic dental injuries because of clinical characteristics, such as, ataxia, large overjet and lip incompetency. Especially, intrusive luxation has rare occurrence but higher incidence of complications. It can be treated by expecting re-eruption, orthodontic reposition, and surgical reposition. Clinicians should be aware of management and follow-up in dealing with cerebral palsy patients who are exposed by intrusive luxation, due to their involuntary movement. This case report describes a 9-year-old male patient with cerebral palsy and epilepsy who experienced intrusion of maxillary permanent central incisor. After one-month follow-up, waiting for spontaneous eruption, pulp necrosis on maxillary permanent central incisor had proceeded. Therefore, surgical reposition with resin wire splint and apexification was performed under conscious sedation with midazolam. After two months, removal of resin wire splint was done. Gutta percha filling and composite resin restoration were performed after sixteen months. During five-year follow-up ankylosis and partial root resorption were observed. But there was no significant complications.

  • In an intra-alveolar root fracture (IARF) of a primary tooth with severe mobility and displacement, extraction and periodic-follow-up is the choice of recommended treatments because of the fear of aspiration of the mobile tooth and the possibility of damage in the permanent succeeding tooth. However, repositioning and splinting are presented as a fresh proposal recently. In case of extracting a primary incisor, many problems occur; esthetic problems; functional problems such as pronunciation and mastication; space loss; and psychological and social problems. Therefore, the best treatment is conservation of the primary tooth. The aim of this report was to suggest the conservative treatment of an Intra-alveolar root fracture of the primary central incisors with severe mobility and displacement based on two cases that describe the diagnoses, treatments and follow-ups (mean period: 27-month). All cases have been treated by reduction and immobilization by resin wire splint (RWS) (mean period: 6-week). Both cases were followed up until the successors were erupted. There have been no complications such as pain, pulp necrosis, periapical lesion, displacement of permanent tooth germ, eruption disturbance and etc.

  • Objective: To analyze the fatigue resistance, debonding force, and failure type of fiber-reinforced composite, polyethylene ribbon-reinforced, and braided stainless steel wire lingual retainers in vitro. Methods: Roots of human mandibular central incisors were covered with silicone, mimicking the periodontal ligament, and embedded in polymethylmethacrylate. The specimens (N = 50), with two teeth each, were randomly divided into five groups (n = 10/group) according to the retainer materials: (1) Interlig (E-glass), (2) everStick Ortho (E-glass), (3) DentaPreg Splint (S2-glass), (4) Ribbond (polyethylene), and (5) Quad Cat wire (stainless steel). After the recommended adhesive procedures, the retainers were bonded to the teeth by using flowable composite resin (Tetric Flow). The teeth were subjected to 10,00,000 cyclic loads (8 Hz, 3 - 100 N, $45^{\circ}$ angle, under $37{\pm}3^{\circ}C$ water) at their incisoproximal contact, and debonding forces were measured with a universal testing machine (1 mm/min crosshead speed). Failure sites were examined under a stereomicroscope (${\times}40$ magnification). Data were analyzed by one-way analysis of variance. Results: All the specimens survived the cyclic loading. Their mean debonding forces were not significantly different (p > 0.05). The DentaPreg Splint group (80%) showed the highest incidence of complete adhesive debonding, followed by the Interlig group (60%). The everStick Ortho group (80%) presented predominantly partial adhesive debonding. The Quad Cat wire group (50%) presented overlying composite detachment. Conclusions: Cyclic loading did not cause debonding. The retainers presented similar debonding forces but different failure types. Braided stainless steel wire retainers presented the most repairable failure type.

  • A 8-year-old patient presented with a crown-root fracture of the maxillary right central incisor with an oblique subgingival fracture line. A multidisciplinary treatment approach including endodontic treatment, surgical extraction and intraalveolar repositioning was used to gain sufficient crown length of the fractured maxillary incisor. The coronally repositioned maxillary right central incisor was stabilized by a resin wire splint. Apexification using MTA was performed. Resin core and direct resin restoration(Cl IV) on fractured teeth was built up. Clinical and radiographic follow-up of the maxillary right central incisor after 36 months showed no signs of root resorption or pathology and acceptable aesthetics and functions were maintained. Surgical extrusion can be considered as a good treatment modality for young patients.
